In general, most at risk are dogs that weigh more than 110 pounds, and also breeds with flat faces — such as pugs and French bulldogs — according to the study in Scientific Reports. The breeds identified at highest risk of heatstroke were: Chow chow, Bulldog, French bulldog, Dogue de Bordeaux, Greyhound, Cavalier King Charles spaniel, Pug, Golden retriever, Springer spaniel. Chow chows, for example, were 16 times more likely to develop heat stroke compared to Labradors. Flat-faced breeds, such as bulldogs, are especially vulnerable because their breathing is compromised by the shape of their skulls, Hall explained. Dogs with shorter muzzles (brachycephalic breeds) have less area to allow heat loss. These dogs also tend to have narrowed airways, which means the dog has to work harder to pant, she said.

Akitas have a low tolerance for heat due to their thick double coat and heavy build. The Alaskan Malamute was bred to pull heavy loads in freezing Alaskan temperatures, making them one of the worst for hot climates. Boston Terriers are brachycephalic, meaning they have a short muzzle that makes it difficult for these dogs to cool themselves off by panting. Boxers are brachycephalic and have high energy levels, they tend to overheat easily. Chow Chows are not well suited for hot weather due to their thick double coat and heavy build. The flat face of an English Bulldog makes this breed prone to overheating. French Bulldogs cannot effectively cool down through panting, and because dogs don’t sweat like humans do, this can be dangerous. Pekingese can’t tolerate hot weather because they have a long, thick coat and because they’re brachycephalic. Pugs don’t do well in hot weather because of their flat face. Saint Bernards can struggle in hot and humid climates thanks to the thick coat that protects them in the mountain snow.
