Heatstroke in Dogs: Signs, First Steps, and Prevention
Heatstroke in Dogs: Signs, First Steps, and Prevention
Every summer, dogs die from heatstroke, often in just a few minutes, and it's usually preventable. Unlike us, dogs don’t sweat; they regulate their temperature almost solely by panting. When it gets too hot, this system can quickly become overwhelmed. Here’s how to recognize the urgency, react, and most importantly, prevent it.
⚠️ Heatstroke is a life-threatening emergency. If in doubt, contact a veterinarian immediately.
Recognizing the Signs of Heatstroke
The first signs appear quickly and can escalate fast:
- Intense, loud panting, with a very droopy tongue
- Excessive drooling, thick saliva
- Gums that are bright red, then more seriously, bluish or pale
- Restlessness followed by lethargy, staggering gait
- Vomiting or diarrhea
- Body temperature above 40 °C (normal is 38–39 °C)
- In severe cases: trembling, seizures, loss of consciousness
Emergency Steps That Save Lives
If you suspect heatstroke, act immediately, every minute counts:
- Move your dog to the shade, to a cool and ventilated area.
- Cool them down gradually with cool (not icy) water: wet their belly, the insides of their thighs, their paw pads, and neck. Ice-cold water can cause shock and constrict blood vessels, slowing down cooling.
- Offer them water at room temperature, without forcing them to drink.
- Fan them (with a fan or your hand).
- Contact a veterinarian right away, even if they seem to be improving: internal complications (kidney, neurological) can arise in the following hours.
Never give human medication and don’t wait to see if “it passes.”
Dogs Most at Risk
Some dogs are particularly vulnerable:
- Brachycephalic breeds (flat-faced): French bulldogs, pugs, boxers… Their breathing is less effective.
- Older dogs, overweight dogs, or those with heart or respiratory issues.
- Puppies and dogs with very thick fur.
How to Prevent Heatstroke
Prevention is simple and incredibly effective:
- Never leave a dog alone in a car, even for a few minutes, even in the shade, even with the windows cracked. The inside can exceed 50 °C in just 10 minutes.
- Walk during cooler hours (early morning, late evening) and avoid hot pavement for their paws.
- Always have cool water available.
- No intense exercise during extreme heat.
- Provide them with a shady spot and, why not, a cooling mat.
In Summary
Heatstroke can kill quickly, but it's almost always preventable. Know the signs, keep emergency steps in mind, and adopt the right reflexes as soon as the heat kicks in. For more on daily well-being, check out our tips on how long to walk your dog.
