A dog’s body temperature is controlled by her mind. When there are increases in temperatures that are outside or there is a dog excited, stressed, or has been exercising, her entire body receives a signal from her brain. In humans, this results in sweating.

Dogs do have some sweat glands, but they are much fewer than in humans and their skin is covered in fur, so this reduces the amount of cooling the sweat can provide.

The most sweat glands in a puppy are around her paw pads. You may see damp footprints from your dog walking on a hard surface in the summertime.

Panting is the way dogs need to cool themselves. It works by allowing heat from the hottest aspect of the body, the thorax, to escape moisture produced by the mucous membranes of the tongue, mouth, and throat. The puppy exhales the air that is moist, and the process of evaporation cools the dog.

Blood vessels in the skin of ears and the face can also help a dog to cool down by bringing hot blood closer to the surface of the body.

If these processes cannot be achieved or the body is overwhelmed and can’t cool itself enough, death and heat stroke may occur.

What Can Make A Dog Too Hot?
True fever
Excitement and stress
Warm air temperatures
Lying near warm objects (heater, another animal, electric blanket, campfire)
Exercise
Being trapped in a car or home that’s too hot
Lack of water or other way to cool off
Lack of shade in warm weather
Does My Dog Have a Fever or Is She Just Hot?

A temperature consistently over 102.8˚ F is cause for concern in dogs. Signs of fever include reluctance to proceed, increased frequency of breathing, depression, anorexia, and lethargy or listlessness.

Hyperthermia is simply an increase in body temperature. This may be due to other causes, excitement, exercise or outside temperatures and isn’t a true fever.

Break her for 20 minutes, then check the temperatures, if you are uncertain whether your dog has a fever. Chances are it is hyperthermia rather than a fever if your dog is behaving normal other than panting and with an increased fever.

What Increases Heat Stroke Risk in Dogs?
Heart or lung disease
Any illness
Brachycephalic breeds, such as pugs or bulldogs
Being overweight
Puppies
Geriatric
Heavy fur such as in sheepdogs
Why Does My Dog Have an Temperature?

Body temperature may be increased due to many things, as mentioned above. Fever increases the body’s set temperature point (the normal temperature range of 100-102.5° F) to help the immune system by activating immune cells to attack the foreign invader, such as a bacterial infection. With increased environmental temperatures and other causes of hyperthermia, the set temperature stage of the body isn’t increased. 1 The body temperature is temporarily increased but can cool off within a short time period as long as cooling mechanisms are not overwhelmed by too much extreme heat.

Emergency Measures for Heat Stroke in Dogs

If your dog is not acting normal or seems to be overheated, contact your veterinarian immediately. Heat stroke can be deadly and is possible in dogs. Death, brain swelling, blood clotting disorders, or organ failure may occur with heat stroke. For an extremely hot dog, she will be cooled by using cool water to the groin, armpits, and the front part of the neck down. Provide fresh water to drink, and contact your veterinarian. Your veterinarian hospitalize your dog for monitoring and further treatments and may give IV fluids.

Thinking and common sense beforehand will permit you to avoid complications from overheating on your dog. If you’re hot, your dog is hot. Dogs are not people–they have their own unique methods for staying cool.
