Heatstroke in Dogs: Signs, Treatment & Prevention

As mid-summer temperatures soar, heatstroke is an ever-present danger for our four-legged friends. In this post, our Hattiesburg and Wiggins vets list the symptoms of heatstroke in dogs, what to do if you suspect your dog is suffering from this serious condition, and advice on how to prevent heatstroke.

What is heatstroke in dogs?

Heatstroke (also referred to as heat exhaustion) is a serious – potentially fatal – danger for dogs. When a dog's body temperature rises above its normal range (101.5°F), they can develop hyperthermia (fever). 

Heatstroke is a type of hyperthermia. It occurs when heat overwhelms the heat-dissipating mechanisms in your dog's body. When your dog's body temperature climbs past 105°F, this indicates heatstroke. 

For this reason, we need to ensure our four-legged friends stay as comfortable and cool as possible during these hot summer months. 

Causes of Heatstroke in Dogs 

On hot summer days, a vehicle's temperature can quickly surge past dangerous levels (even when the inside of our vehicle does not seem "that hot" to us, keep in mind that your dog has a fur coat on, so they will be feeling much warmer). Leave the dog at home while you run errands. 

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

Your dog's breed can also contribute to their risk for heatstroke; short-nosed, flat-faced pooches tend to be more susceptible to breathing issues. As you might imagine, thick coats quickly become uncomfortable. Every dog (even those who love spending time outside engaging in activities) should be closely supervised, especially on days when the mercury rises by the minute. 

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

To help prevent your pooch from getting heatstroke you should be very cautious about how much time your dog spends outside or in the sun during the summer. Do not expose your dog to heat and humidity - their bodies (especially those with short faces) are unable to handle it.

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.

Symptoms of heatstroke in dogs should never be ignored. If your dog is displaying signs of heatstroke, contact our Hattiesburg and Wiggins vets right away to arrange emergency veterinary care
