Summer is a fantastic time to enjoy the outdoors with your pets, but the heat can pose serious risks to their health. High temperatures can lead to dehydration, heat stroke, and even burns from hot surfaces. Here are some essential tips to help you keep your furry friends safe and comfortable during the scorching summer months.

1. Hydration Is Key

Ensure your pets always have access to fresh, cool water. Consider placing multiple water bowls around your home and yard and check them frequently to make sure they are full. Cats usually prefer running water, so consider purchasing a water fountain. For outdoor activities, bring a portable water bottle and bowl so your pet can drink on the go.

2. Avoid the Heat of the Day

Plan your walks and outdoor playtime for early morning or late evening when temperatures are cooler. The midday sun can be intense and dangerous, increasing the risk of heat stroke and burned paw pads from hot pavement.

3. Provide Shade and Ventilation

If your pet spends time outside, make sure they have access to shaded areas. Trees, tarps, or umbrellas can provide relief from direct sunlight. For pets kept indoors, ensure your home is well-ventilated and consider using fans or air conditioning to keep the environment cool.

4. Never Leave Pets in a Parked Car

Even with the windows cracked, temperatures inside a parked car can soar to dangerous levels within minutes. Leaving your pet in a hot car can lead to severe heat stroke or death. If you need to run errands, leave your pet at home in a cool, safe environment.

5. Watch for Signs of Heat Stroke

Heat stroke is a serious condition that requires immediate attention. Symptoms include excessive panting, drooling, lethargy, vomiting, diarrhea, and collapse. If you suspect your pet is suffering from heat stroke, move them to a cool area, offer small amounts of water, and seek immediate veterinary attention.

6. Grooming and Coat Care

Regular grooming can help keep your pet’s coat free of mats and tangles, which can trap heat. However, be cautious with shaving; a pet’s coat provides protection against sunburn and helps regulate their body temperature. Consult your vet or a professional groomer for advice on the best grooming practices for your pet’s breed.

7. Cool Treats and Activities

Help your pet beat the heat with frozen treats and toys. You can make simple ice treats by freezing their favorite snacks in water or broth. Kiddie pools and sprinklers can also provide a fun way for pets to cool off while playing outdoors.
Pro tip: As always, make sure to clean the ears with a veterinary-approved ear cleaner after any water interactions to help prevent ear infections.

8. Mind Hot Surfaces

Pavement, sand, and even artificial grass can become extremely hot and burn your pet’s paws. Before taking your pet for a walk, test the surface with your hand. If it’s too hot for you to touch, it’s too hot for your pet’s paws. Stick to grassy areas or wait until the ground cools down.

9. Regular Health Check-ups

Ensure your pet is up to date with their health check-ups and vaccinations. Some conditions can make pets more vulnerable to heat, and a healthy pet is better equipped to handle the stress of hot weather.

10. Tick and Flea Prevention

Summer is the peak season for ticks and fleas, which can pose serious health risks to your pets. Use veterinarian-recommended tick and flea preventatives regularly. Check your pet’s fur and skin after outdoor activities, especially in wooded or grassy areas. Remove any ticks promptly using tweezers and consult your vet if you notice any signs of flea infestations, such as excessive scratching, red bumps, or hair loss.

By taking these precautions, you can help your pets stay safe, healthy, and happy during the summer heat. Enjoy the sunny season with your furry friends, knowing you’ve done your part to protect them from the dangers of high temperatures.

Stay cool and have a wonderful summer!

Cómo Proteger a tus Mascotas del Calor este Verano

Read in English

El verano es un momento fantástico para disfrutar del aire libre con tus mascotas, pero el calor puede representar serios riesgos para su salud. Las altas temperaturas pueden provocar deshidratación, golpes de calor e incluso quemaduras por superficies calientes. Aquí tienes algunos consejos esenciales para ayudar a mantener a tus amigos peludos seguros y cómodos durante los calurosos meses de verano.

1. La Hidratación es Clave

Asegúrate de que tus mascotas siempre tengan acceso a agua fresca y fría. Considera colocar varios tazones de agua alrededor de tu hogar y jardín y revisarlos con frecuencia para asegurarte de que estén llenos. Los gatos suelen preferir el agua corriente, así que considera comprar una fuente de agua. Para las actividades al aire libre, lleva una botella de agua portátil y un tazón para que tu mascota pueda beber en el camino.

2. Evita el Calor del Día

Planifica tus paseos y el tiempo de juego al aire libre para temprano en la mañana o tarde en la noche cuando las temperaturas son más frescas. El sol del mediodía puede ser intenso y peligroso, aumentando el riesgo de golpes de calor y quemaduras en las patas por el pavimento caliente.

3. Proporciona Sombra y Ventilación

Si tu mascota pasa tiempo afuera, asegúrate de que tenga acceso a áreas sombreadas. Los árboles, lonas o sombrillas pueden proporcionar alivio del sol directo. Para las mascotas que se quedan en el interior, asegúrate de que tu hogar esté bien ventilado y considera usar ventiladores o aire acondicionado para mantener el ambiente fresco.

4. Nunca Dejes a las Mascotas en un Auto Estacionado

Incluso con las ventanas entreabiertas, las temperaturas dentro de un coche estacionado pueden elevarse a niveles peligrosos en minutos. Dejar a tu mascota en un coche caliente puede llevar a un golpe de calor severo o la muerte. Si necesitas hacer mandados, deja a tu mascota en casa en un entorno fresco y seguro.

5. Observa los Signos de Golpe de Calor

El golpe de calor es una condición seria que requiere atención inmediata. Los síntomas incluyen jadeo excesivo, salivación, letargo, vómitos, diarrea y colapso. Si sospechas que tu mascota está sufriendo un golpe de calor, muévela a un área fresca, ofrécele pequeñas cantidades de agua y busca atención veterinaria inmediata.

6. Cuidado y Mantenimiento del Pelaje

El aseo regular puede ayudar a mantener el pelaje de tu mascota libre de nudos y enredos, que pueden atrapar el calor. Sin embargo, ten cuidado al rasurar; el pelaje de una mascota proporciona protección contra las quemaduras solares y ayuda a regular su temperatura corporal. Consulta a tu veterinario o a un peluquero profesional para obtener consejos sobre las mejores prácticas de aseo para la raza de tu mascota.

7. Golosinas y Actividades Refrescantes

Ayuda a tu mascota a combatir el calor con golosinas y juguetes congelados. Puedes hacer golosinas sencillas congelando sus snacks favoritos en agua o caldo. Las piscinas para niños y los aspersores también pueden proporcionar una forma divertida para que las mascotas se refresquen mientras juegan al aire libre. Consejo: Como siempre, asegúrate de limpiar las orejas con un limpiador de orejas aprobado por un veterinario después de cualquier interacción con el agua para ayudar a prevenir infecciones de oído.

8. Cuidado con las Superficies Calientes

El pavimento, la arena e incluso el césped artificial pueden volverse extremadamente calientes y quemar las patas de tu mascota. Antes de sacar a tu mascota a pasear, prueba la superficie con tu mano. Si está demasiado caliente para tocarla, está demasiado caliente para las patas de tu mascota. Quédate en áreas con césped o espera hasta que el suelo se enfríe.

9. Prevención de Garrapatas y Pulgas

El verano es la temporada alta para las garrapatas y las pulgas, que pueden representar serios riesgos para la salud de tus mascotas. Usa preventivos contra garrapatas y pulgas recomendados por el veterinario regularmente. Revisa el pelaje y la piel de tu mascota después de actividades al aire libre, especialmente en áreas boscosas o con hierba. Elimina cualquier garrapata rápidamente usando pinzas finas y consulta a tu veterinario si notas cualquier signo de infestación de pulgas, como rascado excesivo, bultos rojos o pérdida de pelo.

10. Revisiones de Salud Regulares

Asegúrate de que tu mascota esté al día con sus chequeos de salud y vacunas. Algunas condiciones pueden hacer que las mascotas sean más vulnerables al calor, y una mascota saludable está mejor equipada para manejar el estrés del clima caluroso.

Tomando estas precauciones, puedes ayudar a tus mascotas a mantenerse seguras, saludables y felices durante el calor del verano. Disfruta de la temporada soleada con tus amigos peludos, sabiendo que has hecho tu parte para protegerlos de los peligros de las altas temperaturas.

¡Mantente fresco y ten un maravilloso verano!

Ovariohysterectomy (Spay)

Did you know that 25% of female dogs that are not spayed develop mammary tumors? Mammary tumors are commonly diagnosed in older intact female dogs, and the incidence of the development of mammary tumors in dogs is even higher than in humans.

A spay surgery, also called an ovariohysterectomy, involves the removal of the ovaries and uterus in a female dog. Although it is an invasive surgery, it is one of the most common surgeries performed in a general practice veterinary clinic.

There are many benefits to spaying your pet, and the earlier your pet is spayed the better. Complications that may arise during a female dog’s life if she is not spayed include mammary tumors/cancer and pyometra (infection of the uterus).

Additionally, spaying a dog or cat helps reduce pet overpopulation.

Mammary Cancer Risks

As previously mentioned, during a spay the uterus and both ovaries are removed. Ovaries are the female gonads that are responsible for the production of eggs and the female sex hormones, estrogen and progesterone.

Spaying a female dog reduces her risk of developing mammary cancer. If spayed before her first heat cycle, there is almost no risk that she will develop mammary cancer. After she experiences one heat cycle, the risk goes up to 7%. And after more than one heat cycle, the risk goes up to 25%.

Most mammary tumors in dogs are diagnosed between the ages of 9 and 11 years old. Risk of this tumor type is not associated with a specific breed. Small breed dogs, however, appear to be more affected. This suggests a possible genetic component, although one has not yet been identified.

According to information from Cornell University’s Richard P. Riney Canine Health Center, 50% of mammary tumors are malignant. The only way to determine if a tumor is malignant is to remove it and send it to a histopathology laboratory for interpretation.

Mammary Cancer Signs and Diagnostics

Clinical signs of mammary tumors include swollen glands, a painful abdomen, discharge from glands, ulcers near the mammary chain, and lethargy. An easy test that can be performed at most primary care veterinary clinics is called a fine-needle aspirate. This is a non-invasive test that extracts cells from the growth so that a histopathology laboratory can determine if they are cancerous.

A biopsy is a test that is more invasive than a fine-needle aspirate but less invasive than surgical mass removal.

Surgical removal is recommended if mammary cancer is suspected. Diagnostic tests performed before surgery include blood work and chest radiographs to see if the cancer has spread. Treatment ultimately depends on the type of tumor and its behavior.

If you notice any of the clinical signs for mammary cancer in your female dog, please contact your veterinarian.

Pyometra in Dogs

A pyometra is a life-threatening bacterial infection of the uterus that is caused by hormonal changes in an intact female dog. A pyometra is most common in older intact females, but an unspayed dog of any age could get a pyometra. It can occur 1 to 2 months after a heat cycle.

There are two forms of pyometra, closed and open. An open pyometra—the most common form—is when the cervix is open and infection/discharge drains from the vulva. Clinical signs include malodorous discharge from the vulva, lack of appetite, lethargy, vomiting, and drinking an excessive amount of water. Sometimes there are no clinical signs in an open pyometra. Even so, dogs can decline rapidly if not diagnosed early.

With a closed pyometra, the cervix is closed, and the discharge/infection remains inside the uterus. The uterus can rupture in a closed pyometra, and the pet can become septic. This is a medical emergency. Pyometra can be life threatening and the treatment is an emergency spay. Pyometra can be 100% prevented if a female dog is spayed early in life.

Pyometra in Cats

Cats also get pyometra. One major difference in cats, however, is that they rarely appear sick until the very late stages of pyometra. Their abdomen can appear larger and distended due to the size of the discharge-filled uterus. Cats are seasonally polyestrous, meaning that they go into more heat cycles than dogs do, which makes them especially susceptible to getting a pyometra.

As mentioned, an ovariohysterectomy (spay) is a routine procedure performed by many general practice veterinarians. If your female cat or dog is not spayed, please reach out to your local veterinarian to discuss spaying your pet.

Castration (Neuter)

A neuter, also called a castration, involves removing both testicles in a male dog. Testes produce sperm and the male sex hormone testosterone, which is essential for the function of the prostate.

Problems that can arise if a male dog is not neutered include benign prostatic hyperplasia (BPH), prostatitis (infection of the prostate), and testicular cancer. Various studies have shown that neutering a male dog can also help with mounting behavior, inappropriate elimination, and aggression.

Like a spay, a neuter is also a routine procedure and can be performed by most primary care veterinarians. Cats are often neutered under just sedation; the procedure can take less than 5 minutes in cats.

It is highly recommended to neuter your pet after 6 months of age. There is, however, controversy in regard to large breed dogs and bone growth/development. Neutering a large breed dog early has been shown to affect bone growth and lead to joint issues in the future. In a shelter setting, pets are usually neutered at an earlier age to make them more adoptable.

If your male dog/cat is not neutered, please reach out to your local veterinarian to discuss surgery.

Benign Prostatic Hyperplasia (BPH)

Over the course of an intact male dog’s life, the prostate gland gradually enlarges due to the constant hormonal secretion. As an intact male dog ages, the prostate continues to enlarge and that can lead to discomfort/pain. This condition, called BPH, can ultimately interfere with defecation and urination.

Clinical signs of BPH include blood in the urine, difficulty urinating/defecating, and incontinence. An enlarged prostate can often be detected during a rectal exam. These signs however are very nonspecific and can resemble other medical conditions, such as a urinary tract infection, bladder stones, bladder crystals, or bladder tumor.

Neutering a male dog causes the prostate to shrink due to decreased hormonal secretion, which resolves BPH. If a dog has BPH, he will likely need anti-inflammatories and pain medications until surgical removal of the testicles. Ultimately, removing the testicles (neutering) is the treatment of choice.

Testicular Cancer

Testicular tumors are the most common genital tumors found in intact male dogs. Most testicular tumors are malignant, which means they have the potential to spread to other parts of the body.

Testicular tumors usually occur in older dogs, with an average age of 10 years old. The tumors can grow on one or both testicles. Clinical signs include asymmetric testicles, pain near groin, testicular swelling, and visibly larger testicle/testicles. Other signs include poor appetite, weight loss, and lethargy.

Treatment of choice is neutering the pet. Depending on the type of cancer, further treatment such as radiation or chemotherapy might be needed. Diagnostics, including blood work and chest radiographs to check for cancer spread, are performed before surgery.

Neutering your pet eliminates the risk of testicular cancer. If your male dog is intact and you would like to schedule a neuter surgery, please reach out to your veterinarian.

Cystine Crystals/Stones

The amino acid cystine can be excreted in the urine and can lead to the formation of bladder and kidney stones. Although cystine crystals and stones are rare, they are influenced by the presence of sex hormones. These types of crystals and stones are common in intact male dogs and require surgical removal.

Clinical signs may include straining to urinate, blood in the urine, and frequent urination episodes. Due to the anatomical difference in males and females, urinary obstruction is more common in males and it is a medical emergency.

Please reach out to your local veterinarian to further discuss spaying and neutering your pet, as there are many great benefits and various complications can be avoided if performed at an early age.

Por qué deberías esterilizar y castrar a tu perro/gato?

Read in English

Ovariohisterectomía (esterilización)

Sabías que el 25% de las perras que no están esterilizadas desarrollan tumores mamarios? Los tumores mamarios se diagnostican comúnmente en perras mayores intactas y la incidencia del desarrollo de tumores mamarios en perros es incluso mayor que en humanos.

Una cirugía de esterilización, también llamada ovariohisterectomía, consiste en la extirpación de los ovarios y el útero de una perra. Aunque se trata de una cirugía invasiva, se realiza con mucha frecuencia y es una de las cirugías más comunes que se realizan en una clínica veterinaria de medicina general. Hay muchos grandes beneficios de esterilizar a su mascota y cuanto antes se esterilice a su mascota, mejor. Pueden surgir varias complicaciones a lo largo de la vida de una perra si no está esterilizada. Esto incluye tumores/cáncer mamario, piometra (infección del útero) y sobrepoblación de perros/gatos si se crían y producen descendencia, especialmente en la comunidad de animales callejeros.

Cáncer de mama

Como se mencionó anteriormente, durante una esterilización se extirpan el útero y ambos ovarios. Los ovarios son las gónadas femeninas que se encargan de la producción de óvulos y de las hormonas sexuales femeninas (estrógeno y progesterona). Esterilizar a una perra puede ayudar en gran medida a reducir la posibilidad de desarrollar cáncer de mama, independientemente de la edad. Sin embargo, hay varios factores a tener en cuenta. Si una perra es esterilizada antes de su primer ciclo de celo, la probabilidad de que desarrolle cáncer de mama es de casi el 0%. Después de experimentar un ciclo de celo, ese número sube al 7%. Si una perra experimenta más de un ciclo de celo, el número sube al 25%. La mayoría de los tumores mamarios se diagnostican entre los 9 y los 11 años de edad. No hay predilección por la raza, sin embargo, los perros de razas pequeñas parecen estar más afectados, lo que sugiere un posible componente genético. Sin embargo, aún no se ha identificado una mutación genética. Según el Centro de Salud Canina Richard P. Riney de Cornell, el 50% de los tumores mamarios son malignos y la única forma de determinar si un tumor es maligno es extirparlo y enviarlo para su interpretación histopatológica.

Los signos clínicos de los tumores mamarios incluyen glándulas inflamadas, abdomen doloroso, secreción de glándulas, úlceras cerca de la cadena mamaria y letargo. Una prueba fácil que se puede realizar en la mayoría de las clínicas veterinarias de atención primaria se llama aspirado con aguja fina. Se trata de una prueba no invasiva que se realiza habitualmente para evaluar el tipo de células presentes en el crecimiento. Estas muestras se envían para su interpretación histopatológica para evaluar si el crecimiento es canceroso. Otra prueba que se puede realizar es una biopsia, que es más invasiva que un aspirado con aguja fina, pero menos invasiva que la extirpación quirúrgica de masas. La extirpación quirúrgica es la recomendación de elección si se sospecha cáncer de mama. Se realizan varios diagnósticos antes de la cirugía; Estos incluyen análisis de sangre básicos, así como radiografías de tórax para evaluar la metástasis (diseminación). El tratamiento depende, en última instancia, del tipo de tumor y de su comportamiento.  Si se observa alguno de los signos clínicos mencionados anteriormente en su perra intacta, comuníquese con su veterinario local para que se realicen los siguientes pasos apropiados.

Piometra

Una piometra es una infección bacteriana del útero potencialmente mortal causada por cambios hormonales en una perra intacta. Esto es más común en hembras mayores intactas debido a los diversos ciclos de celo de que han pasado, sin embargo, una perra intacta de cualquier edad es susceptible de contraer una piometra. Esto puede ocurrir de 1 a 2 meses después de un ciclo de celo y los signos clínicos incluyen secreción maloliente de la vulva, falta de apetito, letargo, vómitos y beber una cantidad excesiva de agua. Hay dos formas de piometra, cerrada y abierta. A veces, no hay signos clínicos en una piometra abierta, sin embargo, las perras pueden decaer rápidamente si no se diagnostican a tiempo. Una piometra abierta es cuando el cuello uterino está abierto y la infección/secreción drena fuera del cuerpo fuera de la vulva. Esta es la forma más común.  Con una piometra cerrada, el cuello uterino se cierra y la secreción/infección permanece dentro del cuerpo en el útero. De esta forma, el útero puede romperse y la mascota puede volverse séptica. Esto es una emergencia médica. Una piometra puede poner en peligro la vida y el tratamiento para esto es una esterilización de emergencia. Esto se puede prevenir al 100% si una perra es esterilizada a una edad temprana.

Lo mismo se aplica a las gatas, sin embargo, una diferencia importante en las gatas es que rara vez parecen enfermas hasta las últimas etapas de la piometra. Su abdomen puede parecer más grande y distendido debido al tamaño del útero lleno de secreción. Las gatas son estacionalmente poliestroles, lo que significa que entran en más ciclos de celo que las perras, lo que los hace especialmente susceptibles a contraer una piometra.

Como se mencionó, una ovariohisterectomía (esterilización) es un procedimiento de rutina realizado por muchos veterinarios de práctica general. Si tu gata o perra no está esterilizada, comunícate con tu veterinario local para hablar sobre la esterilización de tu mascota.

Castración

Una castración consiste en extirpar ambos testículos en un perro macho. Los testículos producen espermatozoides y las hormonas sexuales masculinas (testosterona), que son esenciales para la función de la próstata. Pueden surgir varios problemas si un perro macho no está castrado. Esto incluye la hiperplasia prostática benigna (HPB), la prostatitis (infección de la próstata) y el cáncer testicular. Se han realizado varios estudios que muestran que la castración de un perro macho también puede ayudar con el comportamiento de montaje, la eliminación inapropiada y la agresión. Al igual que una esterilización, una castración también es un procedimiento de rutina y puede ser realizado por la mayoría de los veterinarios de atención primaria. Los gatos a menudo son castrados bajo sedación y el procedimiento real puede tomar tan solo menos de 5 minutos en gatos.  Se recomienda encarecidamente castrar a su mascota después de los 6 meses de edad, sin embargo, existe controversia con respecto a los perros de razas grandes y el crecimiento/desarrollo óseo. Se ha demostrado que la castración temprana de un perro de raza grande afecta el crecimiento óseo y provoca problemas en las articulaciones en el futuro. En un refugio, las mascotas suelen ser castradas a una edad más temprana debido a fines de adopción.

HPB (Hiperplasia Prostática Benigna)

A lo largo de la vida de un perro macho intacto, la glándula prostática se agranda gradualmente debido a la constante secreción hormonal.  A medida que un perro macho intacto envejece, la próstata continúa agrandándose y eso puede provocar molestias o dolor. Esto se denomina HPB (hiperplasia prostática benigna) y, en última instancia, puede interferir con la defecación y el orine a medida que la próstata continúa agrandándose.

Los signos clínicos de la HPB incluyen sangre en la orina, dificultad para orinar/defecar e incontinencia. Sin embargo, estos signos son muy inespecíficos y pueden parecerse a otras afecciones médicas como una infección del tracto urinario, cálculos en la vejiga, cristales en la vejiga o tumor en la vejiga. La castración de un perro macho hace que la próstata se encoja debido a la disminución de la secreción hormonal cuando se extirpan los testículos, lo que en última instancia previene la HPB. Si un perro tiene HPB, es probable que necesite antiinflamatorios y analgésicos. La extirpación total de los testículos (castración) es el tratamiento de elección.

Cáncer testicular

Los tumores testiculares son los tumores genitales más comunes que se encuentran en perros machos intactos. La mayoría de los tumores testiculares son malignos, lo que significa que tienen el potencial de propagarse a otras partes del cuerpo.  Los tumores testiculares suelen aparecer en perros mayores con una edad media de 10 años. Pueden crecer en uno o ambos testículos y los signos clínicos incluyen testículos asimétricos, dolor cerca de la ingle, hinchazón testicular y un testículo o testículos visiblemente más grandes. Otros signos incluyen falta de apetito, pérdida de peso y letargo.

El tratamiento de elección es la castración de la mascota. Dependiendo del tipo de cáncer, es posible que se necesite un tratamiento adicional como radiación o quimioterapia. Se realizan varios diagnósticos antes de la cirugía, como radiografías de tórax para evaluar la metástasis (diseminación) y análisis de sangre. Castrar a tu mascota eliminará el riesgo de cáncer testicular. Si tu perro macho está intacto y deseas programar una cirugía de castración, comunícate con tu veterinario.

Cristales de cistina

El aminoácido cistina puede excretarse en la orina y provocar la formación de cálculos en la vejiga y los riñones. Aunque los cristales y cálculos de cistina son raros, están influenciados por la presencia de hormonas sexuales. Este tipo de cristales y piedras son comunes en los perros machos intactos y requieren cirugía.

Los signos clínicos pueden incluir esfuerzo para orinar, sangre en la orina y episodios frecuentes de micción. Debido a la diferencia anatómica en machos y hembras, la obstrucción urinaria es más común en los machos y se trata de una emergencia médica.

Comunícate con tu veterinario local para hablar más sobre la esterilización y castración de tu mascota, ya que hay muchos beneficios y se pueden evitar varias complicaciones si se realiza a una edad temprana.

Fear of the Unknown, or Fear of Saying ‘I Don’t Know’?

Originally, I was planning to write this blog about the current “mystery illness” that is popping up in random places around the United States. But when I sat down to research what I could, I kept getting stuck on the word “unknown.” It made me think about all that I haven’t figured out myself yet.

“I don’t know” is a phrase that you are likely to hear from me as your pet’s veterinarian. It is a phrase that I used to be terrified of saying when I first started practicing medicine over a decade ago.

I spent a lot of time (most of my 20s) and money (over six figures) learning everything about biology, chemistry, pharmacology, virology, physiology, anatomy (of multiple species, mind you!), really any animal-related “-ology” so I could avoid that very phrase.

Why I Say ‘I Don’t Know’

Now, with years of experience in the field, I frequently say “I don’t know” because I am so acutely aware that figuring out why an animal is sick (we call this a differential diagnosis) is often much harder than just making an animal feel better (we call this empiric therapy).

There are a few reasons why this is so:

1. Answers often cost money. Even the best veterinarians can go only so far on a physical exam and asking good questions. Eventually we need test results, but this costs money—your money—and sometimes we don’t need an answer to find the treatment. We want to put your resources to the best use. If we use up the available budget to find answers, that may mean we have fewer resources to provide the care your pet needs.
2. Answers often aren’t easy. One of the worst things that has ever happened to any medical professional is the show CSI. They always find the answer in a convenient hour (or 40 minutes if you’re paying for premium streaming). This is just not reality. Yes, sometimes tests to give you a precise answer, but a lot of times testing provides information and clues. Then I use my expensive degree to put all the pieces of the puzzle together.
3. Answers often aren’t universal. This is what I mean when I say a pet “hasn’t read the textbook.” The same problem does not always manifest in the same way in every pet. (Not to put all the blame on cats, but it’s usually cats who haven’t read the textbook!) That can mean that even if we think we know what’s going on, we can get curveballs.

I know this may not instill a lot of confidence in what I and my colleagues do, but I say this because I want you to know that getting an answer isn’t my only goal. I want to help you and your pet in the best way possible. Often these goals are at odds with each other.

We Still Don’t Have an Answer

This brings me to the current “crisis” going on in veterinary medicine right now: the mystery respiratory illness that is affecting dogs. We still don’t have an answer as to what it is. It won’t be easy or cheap to figure out, but there are people working on it. As soon as we have verified information, we will let you know.

For now, we’re left with the general guidance of trying to keep your dog away from crowded canine events as much as possible (I will be boarding my own dog over the Christmas because that’s our only option), keeping them away from unhealthy dogs, and keeping up with the recommended respiratory vaccines like distemper, bordetella, and parainfluenza, and, for some dogs, influenza.

It’s hard accepting “we don’t know,” but to tell you anything more than that would be foolish. In all my years of practice, I would much rather say “I don’t know” than “I was wrong.”

—Dr. Alyssa Kritzman

Diabetes mellitus is a condition in which the body cannot properly produce or respond to the hormone insulin. Insulin regulates the amount of glucose (sugar) in the bloodstream and delivers glucose to the tissues of the body to use as energy. Diabetes results in elevated levels of glucose in the blood. The most common form of diabetes in cats is type 2 diabetes. In type 2 diabetes, glucose levels are high because cells in the body do not respond appropriately to insulin.

Diabetes is the second most common endocrine disease in cats. (The body’s endocrine system consists of several glands—in the case of diabetes, that gland is the pancreas—that make hormones, which are chemical messengers to control organs throughout the body.)

Cats are typically diagnosed with diabetes between the ages of 10 and 13 years. More cats are acquiring diabetes as the number of overweight or obese cats grows. The average cat that weighs 13 pounds or more has about four times the risk of developing diabetes as a smaller cat. Signs of diabetes can include increased thirst, increased urination, weight loss, and increased appetite.

Diagnosis

When a cat is suspected of having diabetes, a veterinarian will perform blood and urine testing. Diabetes is indicated if blood testing shows an elevated glucose level (hyperglycemia) and urine testing shows evidence of glucose in the urine (glucosuria).

Because stress in cats can lead to both hyperglycemia and glucosuria, another confirmation test called fructosamine is usually done. Fructosamine concentration reflects the average glucose concentration for the past 1 to 2 weeks and is not impacted by stress. If this test comes back as elevated, the diagnosis of diabetes is confirmed.

Treatment

Insulin is the treatment of choice for cats with diabetes. This typically requires twice daily administration. In addition, dietary management can be an important component of managing diabetes in cats. A high-protein/low-carbohydrate diet is recommended. Weight loss is also an important component of diabetic management in overweight cats. Weight loss, if attempted, should ideally be gradual, one-half percent to 1% of total body weight lost per week.

The goals of treatment are to maintain a healthy blood glucose, stop or control unintended weight loss, stop or control increased thirst and urination, and avoid hypoglycemia (low blood glucose).

Unlike dogs, cats can reach diabetic remission; these cats have near-normal blood glucose levels without receiving insulin or other blood-sugar–lowering medication. However, cats in diabetic remission require close monitoring to ensure that they do not relapse. Remission is not achievable in every diabetic cat.

Monitoring

Blood glucose curves are used to monitor response to insulin dosing. If a blood glucose curve is performed at home, pet owners measure the first blood glucose reading before the insulin injection. Then, they test every 2 to 4 hours until the next dose of insulin, depending on the type of insulin used. Performing curves at home eliminates the stress of coming to the clinic, which can affect the accuracy of the testing. Owners may need to perform a blood glucose curve several times to find the right dose for their cat.

One method of measuring glucose is by using a glucose meter calibrated for feline blood, such as a AlphaTRAK3. Another way is by using a continuous glucose monitor, such as a FreeStyle Libre. These monitors can be picked up at a human pharmacy and installed by a veterinarian or veterinary technician. Other important monitoring tests include serial bloodwork and urine testing. Your veterinarian will help determine the frequency at which these tests should be performed.

Monitoring your cat’s level of thirst and urination, weight, and appetite are important throughout treatment. These measures can give clues as to how well the diabetes is being managed. Unfortunately, monitoring response to treatment in diabetic cats can be frequent and expensive. 

Complications of Diabetes

One complication of diabetes is diabetic ketoacidosis (DKA). This problem occurs when there is not enough insulin in the body to control the amount of glucose in the blood. DKA happens in uncontrolled diabetics. Without the proper amount of insulin in the body, glucose cannot be used as an energy source. Instead, the body breaks down fat, which produces ketone bodies. With high levels of ketones, the body becomes more acidic, which disrupts fluid and electrolyte balance. Left untreated, the resulting abnormal electrolyte balance may lead to abnormal heart rhythms and muscle function and death. Signs of DKA can include increased thirst or urination, lethargy, weakness, vomiting, increased respiratory rate, decreased appetite, and weight loss.

The other complication is hypoglycemia, or low blood sugar, which may arise when insulin therapy lowers the blood sugar significantly. Signs of hypoglycemia include weakness, lethargy, vomiting, lack of coordination, seizures, and coma. Hypoglycemia can be fatal if left untreated. A diabetic cat that shows any of these signs should be offered its regular food immediately. If the cat does not eat voluntarily, it should be given oral glucose in the form of honey, corn syrup, or dextrose gels and brought to a veterinarian immediately. However, if a cat is seizing or comatose, oral glucose methods should not be attempted. 

If you’ve noticed changes to your cat’s eating and drinking habits as well as weight, please have them seen by a veterinarian for additional testing to be done as soon as possible.

With Chicago’s changing weather, who knows what season we’re currently in right now? And with the season change comes … seasonal allergies, or just allergies in general.

That’s the tricky part that we veterinarians face. We have to investigate and determine what type of allergies your pet is experiencing, and if it is truly allergies versus something else.

As many of you may know, just like people get allergies, so do pets. The signs, however, can be a little different. Many times your pet will show signs of scratching, biting, chewing, and rubbing certain areas of their bodies. You can even see redness, inflammation, fur loss, and, in severe cases, open, infected wounds.

There are many components to allergies, and getting a detailed history from you during the initial vet visit is very important. So although it may seem like an interrogation in the exam room, this is when we are putting all of the puzzle pieces together in our head and thinking of the best diagnostic tests and treatment options for your pet. Each pet is different, and treatment varies on a case-by-case basis.

Flea Allergy

“My cat doesn’t go outside.” “My dog isn’t around other dogs.” “I’ve never seen any fleas on my pet.”

Just because you don’t see them, doesn’t mean they’re not there. Did you know that 1 female flea can lay between 20 and 50 eggs a day?

At times, the only evidence we have to suspect that there are fleas present is flea dirt, which is basically flea feces. Areas that can be affected by fleas include the tail base, neck region, and belly, although fleas can be found anywhere on the body.

A flea allergy is caused by the saliva of the flea itself. All it takes is a few bites to see clinical signs. Fleas can survive at a wide range of temperatures, so it is important to have your pet on flea and tick preventatives year-round to avoid flea allergy dermatitis. Read more about fleas.

Food Allergy

Pets can also have hypersensitivities to certain foods. Although potential allergens can include the food dye, carbohydrates, or preservatives, often it’s the protein source that is the culprit. A food allergy is diagnosed based on a detailed history and, most importantly, a strict food trial.

A food trial consists of feeding your pet a hydrolyzed diet or novel protein for a minimum of 8 weeks. This diet is very strict, and it is important that you only feed the novel protein or hydrolyzed diet. You must not feed any additional foods or treats. Keep in mind that many medications and monthly preventatives can be flavored so you must monitor closely what you are feeding and giving your pet. If after the trial period your pet is symptom free, a food challenge is performed. This consists of introducing the previously fed diet and watching for signs of itching or scratching. More details regarding a food trial can be discussed with your veterinarian. Read more about food allergies.

Seasonal vs Environmental Allergies

These can get tricky and hard to diagnose so, as previously mentioned, a thorough history becomes very important. We must investigate if there is any pattern to the clinical signs. Are the signs happening when it is warmer out vs colder? Do the signs show up after walks or after visiting certain areas, like a park or forest preserve? Every detail matters, so it is important to reach out to your veterinarian when your pet starts experiencing signs of excessive itching, scratching, licking, fur thinning, etc.

Treatment for Allergies

Treatment varies on a case-by-case basis. Ultimately, we want to control your pet’s clinical signs but also make your pet comfortable and clear of any secondary infections. Contact your local veterinarian when you start seeing any of the previously mentioned clinical signs.

There are several allergy medications to try. Each pet is different, and sometimes it can take some trial and error to find what works best for your pet, whether that is a single medication or a combination of medications. Allergy medications come in oral, injectable, and topical formats. Your veterinarian will determine which one suits you and your pet’s lifestyle.

Is It Even Allergies?

Although fur loss, fur thinning, over-grooming, and biting can be signs of allergies, these can also be signs of stress, especially in cats. Fur thinning and fur loss can even be signs of endocrine diseases, such as hyperthyroidism or hypothyroidism.

If your pet is experiencing any of the clinical signs mentioned throughout this post, please reach out to your veterinarian so they can determine the best diagnostic test and treatment options for your pet. You and your veterinarian form a team that wants the best for your pet.

Comezón de la mascota

Read the blog in English.

Con el clima cambiante de Chicago, quién sabe en qué temporada estamos ahora. Y con el cambio de clima llegan… las alergias. Esa es la parte difícil a la que nos enfrentamos los veterinarios. Tenemos que investigar y determinar qué tipo de alergias está teniendo su mascota y si realmente se trata de alergias o de otra cosa.

Como muchos de ustedes saben, al igual que nosotros podemos tener alergias, las mascotas también pueden hacerlo. Sin embargo, nuestros signos pueden ser un poco diferentes. Muchas veces su mascota puede mostrar signos de rascarse, morderse, y masticar ciertas áreas de su cuerpo. Incluso se puede ver enrojecimiento, inflamación, pérdida de pelo y, en casos graves, heridas abiertas infectadas.

Las alergias tienen muchos componentes y es muy importante obtener un historial detallado durante la visita inicial al veterinario. Entonces, aunque pueda parecer un interrogatorio en la sala de examen, al mismo tiempo estamos juntando todas las piezas del rompecabezas en nuestra cabeza y pensando en las mejores pruebas de diagnóstico y opciones de tratamiento para su mascota, ya que cada mascota es diferente y puede variar según el caso.

Alergia a las pulgas

“Mi gato no sale”, “Mi perro no está con otros perros”, “Nunca he visto pulgas en mi mascota”. Que no los veas no significa que no estén ahí. ¿Sabías que una pulga hembra puede poner aproximadamente de 20 a 50 huevos por día? A veces, la única evidencia que tenemos para sospechar que hay pulgas presentes es la suciedad de pulgas, que es básicamente heces de pulgas. Las áreas que pueden verse afectadas por las pulgas incluyen la base de la cola, la región del cuello y el vientre; aunque se pueden encontrar en cualquier parte del cuerpo. Una alergia a las pulgas es causada por la saliva de la pulga y nada más se necesita algunas picaduras para ver los signos clínicos. Las pulgas pueden sobrevivir en un amplio rango de temperaturas, por lo que es importante que su mascota tome medicamentos preventivos contra pulgas y garrapatas durante todo el año para evitar la dermatitis alérgica por pulgas. Leer más sobre pulgas.

Alergia a la comida

Las mascotas también pueden tener hipersensibilidad a ciertos alimentos. Aunque los alérgenos potenciales pueden incluir colorantes alimentarios, carbohidratos o conservantes; lo más común es la proteína que es la culpable. Una alergia alimentaria se diagnostica en base a un historial detallado y una prueba alimentaria estricta. Una prueba de alimentación consiste en alimentar a tu mascota con una dieta hidrolizada o proteína novedosa durante un mínimo de 8 semanas. Esta dieta es muy estricta y es importante que solo le des la dieta proteica o hidrolizada novedosa. No debe alimentar con alimentos adicionales. Tenga en cuenta que muchos medicamentos y preventivos mensuales pueden tener sabor, por lo que debe controlar de cerca lo que alimenta y le da a su mascota. Si tu mascota está asintomática, se realiza un reto alimentario que consiste en introducir la dieta alimentada previamente y vigilar si presenta signos de picor o rascado. Se pueden discutir más detalles sobre una prueba de alimentos con su veterinario. Leer más sobre alergias alimentarias.

Alergias Estacionales y Ambientales

Estos pueden volverse complicados y difíciles de diagnosticar, por lo que como se mencionó anteriormente, un historial completo y detallado se vuelve muy importante. Debemos investigar si existe algún patrón en los signos clínicos. ¿Están ocurriendo los signos cuando hace más calor que cuando hace más frío? ¿Aparecen los signos después de caminatas o después de visitar ciertas áreas como un parque o una reserva forestal? Cada detalle es importante por lo que es importante comunicarse con su veterinario cuando su mascota comience a enseñar signos de picazón excesiva, rascado, lamido, adelgazamiento del pelaje, etc.

Tratamiento para Alergias

El tratamiento varía según el caso. Queremos controlar los signos clínicos de sus mascotas, pero también hacer que su mascota se sienta cómoda y libre de infecciones secundarias. Esto significa comunicarse con su veterinario local cuando comience a ver cualquiera de los signos clínicos mencionados anteriormente. Hay varios medicamentos para la alergia para probar, sin embargo, cada mascota es diferente y, a veces, puede tomar un poco de prueba y error para finalmente encontrar lo que funciona mejor para su mascota. Qué puede significar un solo medicamento o una combinación de diferentes medicamentos. En cuanto a los medicamentos, hay varias opciones orales para probar, así como opciones inyectables y opciones tópicas. Su veterinario determinará cuál se adapta mejor a usted y al estilo de vida de su mascota.

¿Es incluso alergias?

Aunque la pérdida de pelaje, el adelgazamiento del pelaje, el aseo excesivo y las mordeduras pueden ser signos de alergias; estos también pueden ser signos de estrés, principalmente en gatos. El adelgazamiento y la pérdida de pelo pueden incluso ser signos de varias enfermedades endocrinas como el hipertiroidismo o el hipotiroidismo.

Si su mascota enseña alguno de los signos clínicos mencionados en esta publicación, comuníquese con su veterinario para que pueda determinar las mejores opciones de prueba de diagnóstico y tratamiento para su mascota. Somos un equipo y queremos lo mejor para tu mascota.

Osteoarthritis in pets is often thought of as a geriatric pet disease that warrants treatment when our pets are obviously painful and experiencing lameness. However, osteoarthritis often starts younger than you might expect, and pain may be present even before lameness is apparent.

Let’s start with what osteoarthritis is: it’s the most common form of arthritis and it is characterized by painful inflammation and degeneration of one or more joints. Over time, it can lead to bone-on-bone contact.

Many factors contribute to the disease process, including overweight or obesity, abnormal joint development, past injury or orthopedic surgery, and how a pet is built.

In dogs, early signs of this disease can include:

• restlessness or irritability,
• frequent position changes during rest,
• not as fast getting up or sitting down,
• weight shifting while standing,
• less interest in activity or play, and
• hesitation before walking, sitting, or climbing stairs.

Eventually, a dog may begin to limp, to experience stiffness when walking, and to have difficulty going up or down stairs and jumping up or down.

In cats, osteoarthritis may look like a reduction in play, grooming, socializing, and appetite, with increases in hiding and sleeping and changes in urination/defecation habits. Cats can also have trouble jumping up/down, climbing up or down stairs, running, and chasing objects.

Because this disease is painful and progressive, early diagnosis and treatment are important for long-term pain management and slowing the progression of the disease. Treatment includes a combination of pain medication, weight loss or maintenance, dietary changes, environmental modification, and exercise. 

If you feel your pet may be showing signs of osteoarthritis, our clinic can share additional resources on how to know if your pet has this disease and talk with you about treatment options.

After two long years of this pandemic, we still do not know much about pets and SARS-CoV-2 (COVID-19), but over the last few months I have learned a lot. I am writing this blog as I am isolated in my basement with COVID-19. I am thankful for the protection I have received from vaccines as I am only experiencing very mild signs.

Transmission

We believe that transmission to pets is from contact with a positive human within the household. Transmission from pets to humans is considered extremely low. Due to the risk of transmission to pets, the CDC recommend avoiding close contact with pets if you are ill. The occurrence of severe illness in pets is rare, but transmission is possible. Pets presumed positive should remain isolated from other pets until clinical signs have resolved.

Clinical Signs

It is important to remember this is a human pandemic. We know that by comparing the large number of human cases of COVID 19 and the very few cases documented in pets.

I truly believe that most pets do not acquire the virus. If they do, they are typically asymptomatic or have very mild symptoms. The clinical signs I observed in these presumptive positive cases were upper respiratory signs: nasal congestion, sneezing, reverse sneezing, and gag-like cough. These signs were odd and did not fit with classic tracheobronchitis (canine cough). When I examined these dogs, they did not cough when I touched their neck to palpate their trachea, which is the typical response during a physical exam when the patient has classic canine cough.

We have seen patients with clinical signs suspected to be secondary to SARS-CoV-2 in the past 2 to 4 weeks.

Treatment

Unfortunately, there is no approved or documented treatment for COVID in dogs or cats, but in most cases, they do not need treatment. For those pets with more severe clinical signs, I have found that corticosteroids seem to provide the most relief. The brachycephalic breeds seem to have more nasal congestion and difficulty breathing. In these pets, I have started anti-inflammatory doses of steroids and they seem to respond well.

In a few of these cases, chronic rhinitis (irritation/swelling of the mucous membrane in the nose) and sneezing has lasted for weeks to months. Home care for pets is similar to home care for most human COVID-19 cases. The virus needs to run its course. Be sure your pets continue to eat and drink. You can also put the pets in the bathroom with the shower running; the warm humid air can be soothing for the upper airway.

Testing

SARS-CoV-2 testing is not widely available for dogs or cats, but most large veterinary laboratories are offering PCR testing. Antibody testing is not widely available at present. If you feel you dog or cat has signs of SARS-CoV-2 after exposure to an infected person, I recommend contacting your veterinarian.

If you are a client at Medical District Veterinary Clinic, feel free to reach out to me and I may be able to assist in testing as I am collaborating with Dr. Ying Fang, a virologist, at the University of Illinois College of Veterinary Medicine.

For many people, the doctor’s office can be a scary place. So it is no surprise that many pets view going to the vet with a similar fear.

Our clinic truly believes in Fear Free practices. Our goal is to limit your pet’s stress and fear and make visits with us as pleasant as possible. There are various ways that we do this, which I would like to share with you.

Treats, Teats, and More Treats!

During your pet’s visit you will notice that we like to offer treats. We have biscuits, cheese, peanut butter – like a candy store for dogs and cats! This is not only because we think your pet is adorable and we want to spoil them, but this is also a main way we like to bond with them.

Imagine if you are at the doctor and you are anxiously waiting, and then the doctor walks in and immediately offers you your favorite treat (for me, that would be some delicious baked goods) and socializes with you. You would likely feel much calmer and connected to them. This is the equivalent of what we do with your pets.

Although we have lots of treats, if you have a dog or cat that is pickier with food, please feel free to bring whatever your pet likes best. This is not uncommon, as I have seen many patients that would eat only one food.

We encourage owners to offer treats as well during visits to help make the entire experience as positive as possible. We joke that visits go best when our patients come hungry, so you may want to consider bringing your pet to see us with an empty stomach so there is plenty of space for treats!

Getting on Their Level

We want our patients to feel comfortable, so we often will sit on the ground with them. We hope that by sitting on their level they feel less intimidated and fearful, and that they see us as their “friend.” I have noticed that when I sit on the ground and spend time in the room before even beginning my exam, my patients generally seem more at ease.

Please do not feel obligated to sit with us, but if you would like to you are totally welcome!

Limit Stress from Other Pets

Many cats never leave the home except to go to the vet. They may be stressed by traveling before they even arrive.

The smells and sounds of dogs can be very scary for them, too, which is why we recently created a separate feline waiting room and exam rooms. We use all separate supplies, have tasty treats and fun toys, and have nice feline-friendly smells. In the months since we have started using this new space, I have noticed that cats overall seem much calmer and happier. 

Dogs can be become upset from other pets as well. Some of the sweetest and most affectionate dogs that I have met do not get along well with other dogs. Being around other dogs is stressful for them. I personally have a dog-reactive dog, and while she loves people, other dogs make her highly anxious.

To reduce this anxiety, we have multiple tactics, such as choosing specific exam rooms and trying to limit time in the clinic and exam room, when other pets are a trigger for the patient. We also perform exams outside in an isolated area if needed.

Fear Free for Your Pet

Please let us know if your pet is reactive with other pets, or there are any other behavioral concerns, and we will work with you to formulate a plan for their visits.

I hope you can see how much we at Medical District Veterinary Clinic truly care about our amazing patients! We look forward to continuing to make their time with us as fun and enjoyable and fear free as possible!

Well, it’s been 17 months of a global pandemic and it’s the middle of a hot (UN Climate report) summer. Though much has changed since March of 2018, dogs’ anal sac health dramatically has not. Partly because I’m tired, and partly because I answer questions about this about 20 times a day, I wanted to re-run a classic of yesteryear that takes us back to times more innocent, when a postage stamp only cost 50 cents and kids couldn’t get enough of this “texting” craze. Enjoy.

Most of us in the veterinary field face a horrible dilemma. The majority of our days are filled with details and particulars that are deemed rather unfit for discussion at the dinner table, any social gathering, and anywhere outside the professional confines of the clinic. It’s always fun to talk puppies and kittens, but a great deal of what we do during the day revolve around bodily fluids (blood, feces, urine, vomit), wounds, parasites, and the selected greatest and grossest hits of infection and disease.

Anything interesting happen at work today? Yes. Most of it was gross.

So, I’d like to discuss the grossest of all things for one moment. Please feel free to put away your chocolate custard, beef stew, and bean soup, for one moment, while we explore dog and cat anal sac disease.

Cats and dogs have anal sacs located near the periphery of the anus. These sacs excrete a liquid, often when animals defecate, that mixes into their stool and gives forth a particular and specific smell akin to a garbage bag filled with a rotting animal that has been soaked in plague juice.

At times, though, the ducts that excrete the anal sac fluid can become blocked, forcing the sacs to become enlarged, uncomfortable, swollen, and irritated. Sometimes these sacs can become so blocked that they burst forth with a mixture of all of the aforementioned dinner-party unmentionables in one fell swoop. Other times they slowly leak out at convenient times and places such as Sunday morning at 5:13 a.m. on your pillow next to your head. Often, they don’t do anything but get bigger and more uncomfortable. There are times when severe stress and discomfort can cause animals to release their anal sacs all over (seemingly) everywhere in the world.

Owners complain about their dogs and cats “scooting” their back ends over the ground or that their pets are licking their back end obsessively. The clinical signs may be more vague and scary, especially for older animals who have not ever had this problem. We may find out animals straining to defecate (as the sacs block the exit of the anus), walking stiffly, uncomfortable, not interested in eating, and, in extreme cases, vomiting. I’ve seen some dogs become so affected that they scream in pain when touched and refuse to move. I’ve seen some cats stop eating or moving and refuse to go into the litter box.

Why does this happen? you ask (while not at the dinner table). There are a few common reasons:

• Anatomical irregularities that are uncontrollable: Some dogs and cats, for whatever reason, just don’t seem to have anal sacs or anal sac ducts in the right position to allow for easy release. We have seen puppies whose anal sacs fill up monthly and need help.

• An extended period when the animal’s feces are soft and unable to naturally press on the sacs to express them: When animals have parasites (such as Giardia) or chronic diarrhea due to dietary issues or underlying illnesses, we often are not thinking that during the whole of this period, their anal sacs are (metaphorically) laughing with power as they grow bigger.

• Infiltrative disease (such as cancer): This is not very common, though it can occur. The anal sacs become diseased and cancerous. It can happen in any dog, but one tends to see this more in spaniel breeds. It does not have a good prognosis, but this condition is rare. Very rare.

• Animals, especially as they get older, learn different postures to deal with changes in the body. I have seen so many cats and dogs with untreated back pain that have to posture differently to defecate, and because of this, do not seem to express their anal sacs with the same proud efficiency that they once did. As the anal sacs get worse, they become even more uncomfortable, the animals defecate less, develop chronic soft stool, and this glorious cycle continues until you have a cat or dog that is constipated and has horribly painful anal sacs.

What can you do about it?

First, express the anal sacs. This is not something one should just try at home. I am speaking for all citizens of earth, in general, by saying that you should not do this in your kitchen before the family wakes up. Partly, because the smells of putrid sub-par day-old fish byproduct mixed with armpits and feces will probably wake them up, but also I wonder if this aspect of your relationship with your pet is one you really want to explore. While some people do learn to do this at home with their animals, I personally will not do it at home on my animals. But it is possible.

Alternatively, we can express your animal’s anal sacs so you don’t have to watch, smell, see, and, in some tragic cases, taste. We have safe zones in the clinic where no one walks for fear of spraying anal sacs. Some groomers do this for you, but few do them to completion. Ask your groomer before you assume, and talk with us about how soon you should come back for a recheck. Sometimes the anal sacs can be so full and painful that sedation may be required.

Second, animals may need additional treatment, such as antibiotics or anti-inflammatories. Most bad cases of anal sacculits, anal sac impaction, or anal sac abscesses need medication and aggressive rechecks before they are not painful or affected. It’s not generally the case that medications alone will work.

Third, we must remove the cause. Are allergies causing chronic licking, which is causing the anal sacs to be inflamed? Is your animal’s diet not allowing for a normal stool texture? Do you need to add fiber to the diet? Is your dog anxious, and this anxiety manifests in back-end licking? Are there intestinal parasites present? Is there infiltrative disease? Is there a chronic infection? Is there another animal in the house that is over-grooming the affected animal? We need to fix this.

Fourth, sometimes the anal sacs need to be removed. It’s not a cheap therapy, and it is surgery. But sometimes after coming into the clinic every two weeks and having anal sac disease a constant part of their lives, some owners elect to remove them.

As a final note, most dog owners know or have heard of anal sac issues, but most cat people are thinking that this is not applicable. This problem affects many mammals. So I’m sorry to say that even the sweetest of felines has the foulest of anal sac scents. I’ve had a run, lately, of seemingly ill cats who magically became “new” cats after their anal sacs were expressed. And, for those who play with the skunks, beavers, and opossums of your neighborhood, though I’m sure you have more on your mind, also be aware. Humans have them too, but I will let you and your loved ones google that on your own on your non-work computer.

Read things from Canada, do anything related to Canada, enjoy the summer weather noticed when opening the windows after the scent of your animal’s anal sacs permeate the walls of your Chicago apartment.
