Heatstroke in Dogs

Heatstroke in dogs can be a very serious condition if not treated right away. Today, our Fountain Valley vets discuss the causes, signs, treatment, and prevention of heatstroke in dogs.

Heatstroke in Dogs

Heatstroke (a.k.a. heat exhaustion) is a serious and potentially fatal concern for dogs. When a dog’s body temperature is elevated above a normal range (101.5°F), hyperthermia can occur.

Heatstroke is a form of hyperthermia. It happens when your dog’s body is overwhelmed by excessive heat and can't regulate back to a normal temperature. When your dog's body temperature rises past 104°F, they are in danger. If body temperature is above 105°F, this indicates heatstroke.

Causes of Heatstroke in Dogs

A sadly common cause of heatstroke in dogs is people leaving their dogs in the car. On summer days, a vehicle's temperature can quickly exceed dangerous levels. 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.

Your dog's breed could also be a contributing factor when it comes to heatstroke. If your dog is flat-faced or short-nosed they tend to be more vulnerable to breathing issues and more likely to get heatstroke. If your dog is sporting a thick coat they can have more issues with overheating.

Each dog requires close supervision, especially on days when the mercury is rising.

Signs of Heatstroke in Dogs

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

If your dog 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. Immediately take them to a cooler place with good air circulation if you notice your dog displaying any symptoms listed above. If symptoms do not improve quickly, 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. Contact your vet or your nearest emergency vet for further instructions.

Take your dog to a vet right away whether you can reduce their temperature or not.

Preventing Heatstroke in Dogs

To help prevent your dog from getting heatstroke, be very cautious about how much time your dog spends outside or in the sun during the summer. 

Never leave your dog in a car with closed windows, even if you park in the shade.

Don't leave your dog in the car with the windows open a little bit. It still gets way too hot in the car for your dog.

Make sure your dog has shade to retreat to and easy access to cool water.
