Heatstroke is a serious condition that can be potentially fatal for dogs, so owners need to know how to prevent and recognize it. Here, our Arlington vets discuss the heatstroke symptoms in dogs, how to prevent it and when it is a veterinary emergency.
What is heatstroke in dogs?
Heatstroke, a.k.a. heat exhaustion, is a serious and potentially fatal dog issue. Hyperthermia can occur when a dog’s body temperature is above a normal range (101.5°F).
A 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.
What 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 contribute to heatstroke. Flat-faced or short-nosed dogs tend to be more vulnerable to breathing issues and more likely to get heatstroke. Dogs sporting thick coats can also have more issues with overheating.
Each dog requires close supervision, especially on days when the mercury is rising.
Signs & Symptoms of Heatstroke in Dogs
When it comes to heatstroke in dogs, you will need to watch for the symptoms closely, especially during summer. This can include any combination of the following symptoms:
- Collapsing or loss of consciousness
- Diarrhea
- Mental 'dullness' or flatness
- Red gums
- Excessive panting
- Signs of discomfort
- Unable or unwilling to move (or uncoordinated movement)
- Vomiting
If your dog displays any 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 dog displaying any of the symptoms listed above, immediately take it to a cooler place with good air circulation. If symptoms do not improve quickly, contact your vet immediately for advice and to bring them in for an exam if needed.
Take your dog’s temperature if you have access to a rectal thermometer.
If your dog's temperature is above 104°F, it is an emergency, and you will need to take it to the 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 immediately, whether you can reduce their temperature.
How to Prevent Heatstroke in Dogs
To prevent 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. It still gets way too hot in the car for your dog.
Ensure your dog has shade to retreat to and easy access to cool water.
