Dog Heatstroke: Symptoms and Emergency First Aid
Heatstroke in dogs is a true emergency that can become fatal within minutes. Knowing the early symptoms and the correct first-aid steps - and acting fast - gives your dog the best chance. This is not a substitute for veterinary care; it’s what to do on the way to the vet.
Early warning signs
- Heavy, frantic panting and difficulty breathing
- Excessive drooling, thick saliva
- Bright red, then pale or bluish gums and tongue
- Restlessness, then weakness, stumbling or wobbliness
- Vomiting or diarrhoea (sometimes with blood)
- Glazed eyes, rapid heartbeat, collapse or seizures in severe cases
What to do immediately
If you suspect heatstroke, act now:
- Move your dog to shade or air conditioning right away.
- Cool with water - pour or spray cool (not ice-cold) water over the body, especially the neck, belly, armpits and paws.
- Aim a fan at the wet fur to speed evaporation.
- Offer small sips of cool water if your dog can drink - don’t force it.
- Call your vet and go - heatstroke causes internal damage that isn’t visible, so a dog must be seen even if it seems to recover.
What not to do
- Don’t use ice-cold water or ice baths - they can constrict blood vessels and cause shock.
- Don’t cover your dog with a wet towel and leave it - it traps heat. Keep water moving and evaporating.
- Don’t assume recovery means you can skip the vet.
Which dogs are most vulnerable
Flat-faced breeds, thick or dark-coated dogs, puppies, seniors, overweight dogs and those with heart or airway problems overheat fastest. See which dogs are most at risk in hot weather.
Preventing heatstroke
- Walk in the cool hours and avoid midday exertion
- Never leave a dog in a parked car
- Always provide shade and fresh water
- Check conditions first with the paw safety checker
