Dog heatstroke: when to act immediately

A day does not need record temperatures for a dog to overheat. Exercise and enclosed cars can be dangerous, especially for flat-faced, overweight or older dogs.

Recognise an emergency

Unusually heavy panting, lots of drool, weakness, staggering, vomiting, diarrhoea, abnormal gum colour, confusion or collapse are warning signs. If breathing is difficult or your dog collapses, do not wait to finish reading or measure a temperature.

Start cooling and call a vet

Move into shade or a cooler room. Gently pour cold tap water over the body, keeping it away from the nose and mouth to prevent inhalation. A fan or air conditioning can help while the coat is wet. Do not wrap the dog in a wet towel that traps heat, and do not force water into their mouth. Offer drinking water only if they are alert and able to swallow.

Improvement still needs a check

Call the nearest emergency vet immediately and arrange transport while cooling begins. Use ventilation or air conditioning, and continue safe cooling where possible. Looking better does not rule out internal damage.

Reduce the risk

Walk in cooler hours, bring water, allow breaks and avoid hot ground. Never leave a pet in a car, even with a window partly open. Ask your vet about safe exercise for pets with health problems. These first-aid steps do not replace emergency treatment.
