Heat-related illness can develop quickly. The safest approach is to prevent exposure, recognise early warning signs and act immediately if a dog is struggling.
1. Prevent heat exposure
Move walks to the coolest part of the day and shorten or cancel them when conditions are unsuitable. A missed walk is safer than asking a dog to exercise on hot ground or in humid air.
Never leave a dog in a parked vehicle. Provide constant access to fresh water and shade, and remember that puppies, older dogs, flat-faced breeds, overweight dogs and those with heart or breathing conditions may be affected sooner.
- Test the surface with the back of your hand before walking.
- Choose shaded routes and avoid strenuous games.
- Carry water, but do not rely on water to make unsafe exercise safe.
2. Recognise danger signs
Heavy panting that does not settle, excessive drooling, weakness, confusion, vomiting, bright-red or very pale gums, collapse and seizures can indicate a medical emergency. Do not wait for every sign to appear.
A dog that suddenly slows down, seeks shade or refuses to continue is already communicating that conditions are too much.
3. Act immediately
Move the dog into shade or a cooler area, offer small amounts of water and begin cooling with cool—not ice-cold—water. Wet the body, especially the underside, and use airflow if available while arranging urgent veterinary advice.
Continue cooling during transport if the veterinary team advises it. Delayed treatment can allow organ damage to progress even when the dog appears to improve.
- Stop exercise and move the dog out of the heat.
- Cool gradually with cool water and airflow.
- Telephone a veterinary practice immediately.
