In order to ensure your animal does not end up needing pet medication for heatstroke, it is important to keep them cool, a charity has said.
The RSPCA has urged owners to be aware of the dangers of hot weather following the recent bout of sunshine.
Some dogs are more prone to suffer from heatstroke, with old, young, overweight and heavily muscled dogs more at risk.
Short-nosed and long-haired dogs are also more likely to be affected by it.
Symptoms of heatstroke include excessive panting and profuse salivation. If dogs show these signs, it is important to put pets somewhere cooler and contact a vet for advice.
It is also important not to leave pets in hot cars, the charity said.
David Bowles, RSPCA director of communications, said: "I think [people] just don't think anything bad will happen to their pets, particularly if they're just leaving them for a few minutes.
"What people need to realise is that the next animal to die in a hot car, conservatory or outbuilding could be their pet - that's how serious this is."
