How to Detect a Fever in Dogs

Fever in a dog is typically a sign that the body is fighting infection. The most accurate way to detect a fever is by taking your dog's rectal temperature, although other symptoms may be apparent. A normal temperature for a dog is 100.5 to 102.5 degrees Fahrenheit. Call your veterinarian if your dog's temperature is above 103 degrees.

      Take your dog's temperature with a rectal thermometer designed for dogs. Use a digital thermometer, which you can purchase from a pet store or online.

      Watch how he acts. If your usually happy and hyper puppy is acting lethargic, he may have a fever.

    • 3

      Follow your dog around after he eats. Vomiting or diarrhea may be a sign that he is not well and suffering from a fever.

    • 4

      Shivering, loss of appetite, coughing and general bad mood can all be signs or symptoms of a fever in your dog.
