According to a study, heatstroke in pets is anticipated to increase as a result of climate change.
Pet owners have been advised that they may need to evaluate their animals' habitat to avoid heatstroke during the summer months.
A five-year research at Nottingham Trent University (NTU) looked at data from a network of UK veterinarians.
Dogs were found to be the most common victims of heatstroke, but cats, guinea pigs, rabbits, and ferrets were also affected.
Researchers predicted that cases would continue to climb as the world warms as a result of climate change.
The Small Animal Veterinary Surveillance Network provided the study with data from participating veterinary offices.
There had been 146 occurrences of heatstroke in dogs, according to the Nottingham team.
Bulldogs and other brachycephalic dog breeds, which have flat features, were particularly vulnerable.
The data also revealed that 16 cats, eight guinea pigs, three rabbits, and a pet ferret were all treated for heatstroke.
Dr. Anne Carter, an NTU researcher, said: Heatstroke in pets is often misunderstood to be limited to dogs in hot cars.
Not only for dogs, but for the entire pet population, we need to do more to promote awareness of risk factors.
Owners of small animals like rabbits, ferrets, and guinea pigs may need to assess their pet's housing and take precautions to keep their creatures cool throughout the summer.
The overall estimates for heatstroke are likely to be far higher, according to the researchers, who say that many cases go unnoticed by owners.
Abnormal breathing, lethargy, collapse, and gastrointestinal difficulties, such as diarrhoea, were the most common symptoms in all of the animals.
Heat-related disease can affect all pets and is likely to become increasingly widespread as global temperatures rise, said researcher and veterinarian Emily Hall.
