How Do You Know if Your Dog Has a Fever?

As a responsible pet owner, it is important to be aware of the signs and symptoms of illness in your dog. One common ailment that can affect dogs is a fever. Just like humans, dogs can experience an increase in body temperature as a result of an infection or illness. But how do you know if your dog has a fever? Here are some signs to look out for:

1. Changes in behavior: A dog with a fever may appear lethargic, less active, and show a lack of interest in activities they usually enjoy.

2. Loss of appetite: When a dog has a fever, they may lose their appetite and have little or no interest in food.

3. Increased thirst: Dogs with a fever may drink more water than usual as their body tries to cool down.

4. Warm ears and nose: While not always accurate, warm ears and nose can be a sign of a fever in dogs.

5. Shivering or trembling: Some dogs may experience chills and shivering when they have a fever.

6. Coughing or sneezing: A fever can often be accompanied by other respiratory symptoms such as coughing or sneezing.

7. Vomiting or diarrhea: In some cases, a fever can cause gastrointestinal distress, leading to vomiting or diarrhea.

If you suspect your dog has a fever, it is important to take their temperature using a rectal thermometer. A normal temperature for dogs ranges between 99.5°F and 102.5°F. Anything above this range may indicate a fever, and you should consult your veterinarian for further guidance.
