Heatstroke in Dogs

Here, our Corpus Christi vets define heatstroke in dogs and provide a list of symptoms that you should watch out for as the temperature rises. We also share recommendations on how to prevent heatstroke and what to do if you think that your dog is suffering from this serious condition.

What is heatstroke in dogs?

As hot weather arrives, heatstroke (also known as heat exhaustion) is a serious — potentially fatal — danger for dogs. When a dog’s body temperature is elevated above a normal range (101.5°F), hyperthermia (fever) can occur.

Hyperthermia takes the form of heatstroke. It takes place when your dog's body's natural systems for dissipating heat are overpowered. Your dog enters the danger zone when their body temperature exceeds 104°F. Heatstroke is indicated if the body temperature is greater than 105°F.

That’s why we need to ensure our dogs stay as cool and comfortable as possible during the summer months.

Causes of Heatstroke in Dogs

On summer days, a vehicle's temperature can quickly exceed dangerous levels (even when the inside of our vehicles do not seem “that hot” to us, remember that your dog has a fur coat on). Leave the dog at home while you shop.

A lack of access to water and shade in your backyard or at the beach can also spell trouble. Shade and water are vital on warm weather days, especially for dogs with medical conditions such as obesity, and senior dogs.

The breed of your dog may also play a role in the development of heatstroke; flat-faced, short-nosed puppies are more prone to breathing problems. As you might imagine, wearing thick coats is uncomfortable after a while. Every dog needs close supervision, even those who enjoy spending time outdoors engaging in activities, especially on days when the temperature is rising.

Heatstroke Symptoms in Dogs

During spring and summer, watch carefully for signs of heatstroke in dogs, including any combination of the following symptoms:

  • Mental “dullness” or flatness
  • Red gums
  • Excessive panting
  • Drooling
  • Signs of discomfort
  • Unable or unwilling to move (or uncoordinated movement)
  • Diarrhea
  • Vomiting
  • Collapsing or loss of consciousness

If your pooch is displaying any of the above heatstroke symptoms it's time to take action.

What To Do If Your Dog Shows Signs of Heatstroke

Fortunately, heatstroke in dogs can be reversed if detected early. If you notice your pup displaying any symptoms listed above, immediately take them to a cooler place with good air circulation. If symptoms do not improve quickly and you are not able to take your dog’s temperature, contact your vet immediately for advice. 

Take your dog’s temperature if you have access to a rectal thermometer. If their temperature is above 104°F, this qualifies as an emergency and your dog will need to see a vet. If this temperature is above 105°F, immediately hose or sponge your dog’s body with cool (not cold) water. Pay special attention to their stomach. A fan may also be useful. Contact your vet or your nearest emergency vet for further instructions.

Heatstroke is a very serious condition. Take your dog to a vet right away whether you are able to reduce their temperature or not.

How to Help Prevent Your Dog From Getting Heatstroke

Be extremely cautious about how much time your dog spends outdoors or in the sun during the summer to help prevent heatstroke in your canine companion. Your dog's body can't handle heat and humidity, especially if they have short faces. Avoid exposing them to these conditions.

NEVER leave your dog in a car with closed windows - even if you park in the shade. Provide your pooch with lots of shade to retreat to and easy access to cool water. A well-ventilated dog crate or specially designed seat belt for dogs may also work well.
