Preventing heatstroke means limiting heat exposure and exertion before your dog starts to struggle. Keep fresh water, shade and a cool, ventilated resting place available; exercise during cooler hours; avoid hot ground and strenuous activity in warm or humid conditions; and never leave a dog in a hot enclosed space. If you suspect heatstroke, start cooling your dog and contact a veterinarian urgently.
Make your dog’s surroundings safer
Provide water, shade and a cool place to rest
Keep fresh water available at home and bring water for outings. Make sure your dog can get out of direct sun and rest somewhere cool with good airflow. Shade matters during walks and time outdoors, not just in the yard.
A portable water dispenser can make it easier to offer water away from home, but it cannot make a hot, strenuous outing safe by itself.
Keep dogs out of hot enclosed spaces
Never leave a dog in a parked car, even in the shade or with the windows cracked. A conservatory, caravan or outbuilding can also become dangerously hot. Take your dog along only when you can keep it in a cool, ventilated environment; otherwise, leave it at home.

Choose safer times and routes for exercise
Walk during cooler hours
Schedule walks, runs and hikes for cooler mornings or evenings. Avoid the hottest part of the day, and skip strenuous activity when conditions are particularly warm or humid. Take breaks and bring enough water. If the weather is hot, shorten the outing or choose a quieter, cooler activity instead.

Heat-related illness is not only a risk in cars. The RSPCA says dogs are 10 times more likely to suffer heat-related illness from exercising in hot weather than from overheating in cars. The page does not state the underlying study’s year or methodology, so treat this as an RSPCA-attributed comparison rather than a newly verified primary-study result: RSPCA advice on walking dogs in hot weather.
Avoid hot ground
Choose cool ground, such as grass, and avoid sun-heated asphalt, pavement and sand. Hot surfaces can contribute to your dog’s heat load, especially if it cannot move into shade or onto cooler ground. Let your dog rest somewhere shaded rather than pressing on across exposed surfaces.

Give higher-risk dogs extra protection
Some dogs may have more difficulty coping with heat and need more conservative plans. Take particular care with:
- Flat-faced or short-muzzled dogs.
- Dogs with heart, respiratory or other relevant health conditions.
- Dogs that are overweight, unfit or have thick coats.
- Very young dogs and older dogs.
Ask your veterinarian for advice tailored to your dog’s health, age and build. Do not assume that a dog accustomed to walks is safe to exercise in hot or humid weather.

Recognize heatstroke and respond urgently
Warning signs
Signs of heatstroke can include excessive or persistent panting, noisy or difficult breathing, heavy drooling, restlessness, weakness or lethargy, unsteadiness, confusion, abnormal gum or tongue color, vomiting, diarrhea, muscle tremors, seizures or collapse. Do not wait for every sign to appear: breathing difficulty, weakness, confusion, seizures or collapse require urgent veterinary attention.
What to do if you suspect heatstroke
- Stop activity and get your dog out of the heat. Move to shade or a cool environment with airflow.
- Begin cooling with water and airflow. Use water cooler than your dog’s body temperature and fan or otherwise provide airflow. The RSPCA advises that cold water rarely causes shock in an overheated dog and says dousing or immersing the dog in cold water is vital to recovery: RSPCA heatstroke guidance.
- Call a veterinarian promptly. Arrange urgent veterinary assessment; cooling at home is not a substitute for professional care.
- Transport in a cool, ventilated vehicle. Continue cooling as appropriate while travelling and follow the veterinarian’s instructions.
Do not drape a damp towel over an overheated dog: the RSPCA warns that it can trap heat. Its separate summer-care guidance suggests a damp towel for a dog to lie on if it is re-wetted frequently. If you use that method, keep the towel under the dog, re-wet it often, and do not delay veterinary help.
