The sweltering UK heatwaves have brought a fresh concern to pet owners' minds: the risk of heatstroke in their beloved companions. Unlike previous years, this isn't just about dogs being left unattended in hot cars or walkers ignoring the dangers of midday strolls.
According to Dr. Katharine Nelson, Director of General Practice at the Royal Veterinary College, while public awareness has significantly reduced these common scenarios, a notable increase in heatstroke cases is now occurring under less obvious circumstances. These include dogs overheating when simply lying in sunny gardens or cats experiencing stress during travel in carriers.
Vet Dave Martin, head of welfare at Inspiring Vet Care, echoes these concerns, highlighting that owners are being caught out by less apparent dangers. This includes animals getting trapped in hot greenhouses, rabbits suffering in hutches with insufficient shade, and dogs lying in sunny spots without access to water or shelter.
Dr. Nelson warns that certain breeds and conditions make pets more susceptible to heatstroke. These include flat-faced breeds, animals with thick coats, and those with pre-existing respiratory problems or heart disease, which can be destabilised by the extreme temperatures. Owners should look out for signs of struggling pets, such as heavy panting, confusion, lethargy, and vomiting.
Vets advise owners to take precautions, ensuring their pets always have access to fresh water and considering using fans. For dogs, it's best to skip walks during extreme heat and opt for indoor mental stimulation instead. For cats, postponing stressful activities or travel until temperatures drop is crucial. If travel is unavoidable, use a well-ventilated carrier with a damp towel in an air-conditioned vehicle.
Nearly 66% of the 355 suspected heatstroke incidents reported by Inspiring Vet Care in 2025 occurred during summer, representing a 28% increase from 2024. Owners are urged to take action now and keep their pets cool, just as they would their own homes – by closing curtains during the day, for example.
