What is the treatment for heatstroke in dogs?

Heatstroke in dogs isn’t just a summertime nuisance—it’s a life-threatening emergency that can strike even on mild days if conditions align.

Heatstroke in dogs isn’t just a summertime nuisance—it’s a life-threatening emergency that can strike even on mild days if conditions align. Those thick fur coats and limited sweat glands mean our canine companions rely almost entirely on panting to cool down, and when that system fails, their body temperature can spike to dangerous levels in minutes.

Recognizing the signs is the first step. A dog with heatstroke might pant excessively, drool thickly, or become unsteady on their feet. Their gums could turn bright red or purple, and they might vomit or collapse. If you spot these symptoms, acting fast isn’t just smart—it could be legally crucial, too. Many regions have laws requiring pet owners to provide adequate protection from extreme temperatures, and failing to address heatstroke promptly might even lead to investigations.

Start by moving the dog to a shaded or air-conditioned area immediately. Wet their coat with cool (not cold) water—focus on the belly, paws, and groin, where blood vessels are close to the skin. Avoid ice or freezing water, as it can constrict blood vessels and trap heat inside. Offer small sips of cool water, but don’t force them to drink; a stressed dog might inhale water and develop aspiration pneumonia.

Contact your vet right away, even if the dog seems to improve. Internal organs like the kidneys and brain can suffer damage from high temperatures, and professional care might include IV fluids, oxygen therapy, or medications to address inflammation. Keep track of the time since symptoms appeared—this information helps vets assess the severity of the situation.

Prevention is always better than treatment, especially when it comes to heatstroke. Never leave a dog in a parked car, even with the windows cracked—temperatures can rise by 20 degrees in just 10 minutes, and dozens of dogs die this way each year. On hot days, adjust walks to early morning or evening, and test pavement with your hand first; if it’s too hot for you to touch, it’s too hot for their paws.

Knowing how to respond to heatstroke could save your dog’s life. Stay vigilant, act quickly, and remember that keeping your pet safe from extreme heat isn’t just an act of care—it’s often a legal responsibility. With the right knowledge, you can help your furry friend beat the heat and stay healthy all year round.
