How To Recognize a High Fever in Dogs

How To Recognize a High Fever in Dogs

The symptoms of fever in dogs can be difficult to diagnose which can cause a delay in treatment for the underlying cause. Here, our internal medicine vets in Alpharetta share some of the signs of a high fever in dogs, what the causes are and how you can help care for your dog.

Internal Temperature: What Is Considered Normal For My Dog?

A dog’s normal body temperature ranges from 101° to 102.5° Fahrenheit, which is significantly higher than humans whose body temperature ranges from 97.6° to 99.6° F. 

A temperature of more than 103° F is considered a dog fever. When temperatures reach 106° F, serious and fatal complications can occur. 

What Steps Should I Follow to Take my Dog's Temperature? 

It can be difficult to detect fevers in dogs because their body temperatures can also increase when they are very excited or stressed. Also, a dog’s temperature can vary throughout the day and sometimes at night.  Therefore, it is important to understand your dog’s healthy temperature. You can determine this by noting your dog's temperature at various times of the day, for several days.

Some people believe that if you feel your dog’s nose and if it’s wet and cold your dog’s temperature is fine, and if it is hot and dry it means a fever.  However, this is not an accurate indicator that your dog has a fever.  

The best way to check your dog’s temperature is to use a digital thermometer for rectal use, some pet stores carry thermometers made just for pets.  It is recommended that you keep a separate thermometer just for your dog and store it where you keep your dog’s supplies. 

Start by lubricating the tip of the thermometer with petroleum or water-soluble lubricant. Then lift your dog’s tail up and to the side and carefully insert the thermometer about 1 inch into your dog’s rectum. If possible, have a second person assist you by holding under the dog’s hind legs to prevent your dog from sitting. Once the thermometer temperature has registered you can carefully remove the thermometer.  

What Are Some Causes of Fever in Dogs? 

A variety of illnesses and internal medicine conditions may cause a fever in your dog. These include:

  • A bacterial, fungal, or viral infection
  • An ear infection
  • An infected bite, scratch, or cut 
  • Tooth infection or abscess
  • Urinary tract infection 
  • Ingestion of poisonous materials, such as toxic plants, human medications, or human foods that are toxic to dogs

In some cases, a dog’s fever cannot be readily determined, this is often referred to as a fever of unknown origin or FUO. In these cases, a fever could be caused by underlying disorders of the immune system, bone marrow problems, or cancer so proper examination and testing by a vet internist is necessary.

What Are the Signs of a Fever in Dogs?

If you notice a significant change in your dog’s behavior this will be your first sign that your dog is not well. You should keep a careful eye on your dog and take note of your dog's symptoms. Any combination of the following symptoms is a good indication that you should check your dog’s temperature and potentially bring them in for veterinary internal medicine in Alpharetta.  

The most common symptoms of a fever in dogs are: 

  • Red or glassy-looking eyes
  • Warm ears and/or nose 
  • Shivering
  • Panting 
  • Runny nose 
  • Decreased energy 
  • Loss of appetite
  • Coughing 
  • Vomiting

Caring For a Dog That Has a High Fever

If your dog’s fever is 106° F or higher immediately take your dog to a local veterinary emergency clinic

If your dog has a fever, of 103° F or more, you can help to cool your dog’s body temperature by applying cool water with a soaked towel or cloth to your dog's ears and paws and running a fan near your dog.  Stop applying the water when your dog’s temperature drops below 103° F.  Continue to monitor your dog closely to ensure that the fever doesn’t return and contact our internal medicine vets in Alpharetta if it does.  

While you should try to get your dog to drink as much water as possible you should never force your dog to drink.

It is important to never give your dog human medications, such as acetaminophen or ibuprofen. These medications are poisonous and may be potentially fatal for your dog.

If your dog exhibits any other symptoms, such as shivering, panting, and vomiting you should have them seen as soon as possible by our internal medicine vets in Alpharetta.
