Heatstroke in Dogs: Symptoms, Causes & What to Do

Heatstroke in dogs is a serious and potentially fatal condition, but it is preventable. In this article, our vets in Redmond will outline the symptoms to watch for and the actions to take if you suspect your dog is suffering from this condition. They will also provide prevention tips.

Heatstroke in Dogs

As you and your dog enjoy the warmer months, it's important to be aware of the risk of heatstroke (or heat exhaustion). Heatstroke can be serious and even fatal for dogs when their body temperature exceeds the normal range of 101.5°F. This condition, known as hyperthermia, occurs when a dog's body can't handle excessive heat.

Once a dog's body temperature goes past 104°F, they are in the danger zone, and if it goes above 105°F, it indicates heatstroke. Therefore, keeping your dog cool and comfortable during the summer is crucial.

What are the signs and symptoms of heatstroke in dogs?

During spring and summer, watch your canine companion closely. Heatstroke often triggers the following signs and symptoms in dogs:

  • Your dog being unable or unwilling to move (or uncoordinated movement)
  • Appearing mentally dull or flat
  • Excessive panting
  • Drooling
  • Diarrhea
  • Vomiting
  • Red gums
  • Signs of discomfort 
  • Collapsing or loss of consciousness

What causes heatstroke in dogs?

During hot summer days, the temperature inside your vehicle can quickly become dangerous for your dog. Even if it doesn't feel too hot for you inside the car, remember that your dog's fur coat makes it much more difficult for them. Leaving your dog home while shopping is best to keep them safe.

Certain dog breeds are more susceptible to heatstroke, especially those with short noses and flat faces, as they are prone to breathing problems. Dogs with thick coats can also get very uncomfortable in the heat. All dogs, even those who love being outdoors, need supervision, particularly on the hottest days.

What should I do if I suspect my dog is suffering from heatstroke?

Heatstroke in dogs can be reversed if detected early. If you notice your dog displaying any of the above symptoms, immediately take him to a cooler place with good air circulation. If symptoms do not improve quickly and you cannot take your dog’s temperature, contact your vet immediately for advice. 

If you can access a rectal thermometer, take your dog’s temperature. If it's less than 105°F, this qualifies as an emergency, and your dog must see a vet. If the temperature is above 105°F, hose or sponge your dog’s body with cool (not cold) water.

Please pay special attention to his stomach. A fan may also be helpful. After a few minutes, retake his temperature until it gets down to 103°F. Do not reduce the temperature below 103°F, as this can also lead to problems. Take your dog to a veterinarian immediately, whether you can reduce his temperature or not.

How can I prevent heatstroke?

It's crucial to be careful about how much time your furry friend spends outside or in the sun during the summer. Don't expose your dog to heat and humidity, especially those with short faces as their bodies cannot handle it.

Never leave your dog in a car with closed windows, even if you park in the shade. Make sure your dog has access to plenty of shade and cool water. A well-ventilated dog crate or a specially designed seat belt may also work well.
