Every dog owner knows that summer temperatures can be dangerous to their pet, especially when a dog is left in a hot car. What you may not know is that some dogs are much more susceptible to the heat than others.
Reporting on a British study, The New York Times recently indicated that "Big dogs, older dogs, dogs with flat faces and certain breeds are all at higher risk of illness or death in hot weather. ... Nine breeds were at significantly higher risk than others, and five of them have flat faces: Bulldogs, French bulldogs, dogues de Bordeaux, chow chows and pugs. Greyhounds, English springer spaniels, Cavalier King Charles spaniels and golden retrievers were also at higher risk."
Care should also be taken with dogs older than twelve, since they have a 75 percent higher risk for illnesses caused by excessive heat. Dogs that weigh over 110 pounds are also at higher risk. And for all you mixed breed/shelter dog owners, you'll be happy to know that purebred dogs have an 85 percent higher risk than mixed breeds.
