Heat Warning for Dog Owners

Dogs do not actually sweat. They exchange heat through panting and to a minor degree, through their feet pads. Additionally, our canine friends do not tolerate high environmental temperatures as well as humans do.

Risk groups

The risk groups are much the same as humans: old, obese, suffer from medical conditions or take medicine. Certain breeds are more susceptible to heat emergencies than other breeds. These breeds with a broad, short skull: Boxers, Bulldogs, Pugs, etc.

Causes of heat emergency in dogs

• Strenuous exercise in hot, humid weather
• Elevated temperatures from atmospheric temps and hot surface contact
