Fever In Dogs And Cats

Fever in dogs and cats is a common sign of inflammation or infection. It serves as a defense mechanism, indicating that the body is fighting off an underlying issue. In this blog, we will explore the causes, symptoms, diagnosis, treatment, and prevention of fever in our beloved pets.

Causes of Fever in Cats & Dogs

Fever can be triggered by various factors such as infections, inflammation, immune system disorders, trauma, heat stroke, tumors, allergic reactions, seizures, pain, stress, exertion from exercise, and even certain medications and vaccines. It’s important to identify the root cause of the fever to provide appropriate treatment.

Symptoms of Fever in Dogs & Cats

Keep an eye out for the following signs that may indicate your pet has a fever:

  • Dullness and lack of energy.
  • Anxiety or nervous behaviors.
  • Increased rate of breathing.
  • Reduction in appetite.
  • Increased thirst.
  • Trembling or shaking.
  • Gums that are redder or pinker than usual.
  • Increased heart rate.

If your pet exhibits these symptoms along with an elevated temperature, it’s crucial to seek advice from your veterinarian. A temperature above 104ºF (40ºC) requires urgent medical attention.

Diagnosing Fevers in Cats & Dogs

To accurately determine if your pet has a fever, it’s best to take a rectal temperature. Other methods like checking the ears, nose, tongue, or paws are not reliable indicators. Remember that the resting temperature for a healthy pet is about 100ºF (38ºC). Taking your pet’s temperature using Mella underarm thermometer can help establish their normal temperature range.

Treating Fevers in Pets

If your pet has a mild temperature increase (below 102ºF/39.2ºC) and is otherwise fine, you can monitor them closely for any other concerning symptoms. Contact your primary veterinarian for advice on whether a visit is necessary. In the meantime, ensure your pet gets ample rest, and access to water (avoid forcing them), and has a healthy appetite.

In cases where the fever persists, worsens, or is accompanied by other signs of infection or illness, your veterinarian may recommend a thorough examination. Diagnostic tests such as blood samples, X-rays, or ultrasounds may be performed to identify the underlying issue. Treatment will depend on the cause, and in some cases, hospitalization with intravenous fluid therapy might be necessary.

Preventing Infections in Dogs & Cats

While it’s challenging to prevent all infections, you can take proactive measures to protect your pets. Ensure they are up to date on vaccinations and protected from parasites that can cause serious diseases. Monitoring your pet’s behavior and recognizing abnormal symptoms will help you identify illness early. If your pet is unwell, keep their toys, food, and water bowls separate from those of healthy pets to prevent the spread of infections.

When to Contact A Veterinarian

If your pet has a high temperature and appears unwell, or if you notice any concerning symptoms, reach out to your veterinarian for professional advice. For temperatures exceeding 104ºF (40ºC), contact an urgent care veterinary hospital immediately.


Fever in dogs and cats is a significant indicator of an underlying issue that requires attention. By recognizing the symptoms, seeking appropriate veterinary care, and taking preventive measures, we can ensure the well-being and health of our beloved furry companions. Remember, your veterinarian is the best resource for guidance when it comes to your pet’s health.
