Heat Stroke
Dogs and cats do not sweat as people do, therefore, the combination of high temperatures, high humidity, and poor ventilation can be fatal.  They must rely on the radiation of heat from the skin surface and panting as their main means of controlling their body temperature.  When the air temperature and humidity are high and the air circulation is reduced, the animals cooling mechanisms simply are inadequate.
If the animal’s body temperature rises dramatically, they may collapse or go into severe shock.  They may die if not promptly treated.  Dogs with short pushed-in noses such as Pugs, Bulldogs, Pekingese, and Boxers are especially susceptible because their restricted breathing prevents the air exchange needed for rapid heat loss.
Treatment consists of reducing the body temperature and administering medication for shock.  Some cases may require hospitalization.
Prevention of heat stroke means providing your pet protection from the sun, adequate ventilation, fresh water at all times, and restricted activity during hot, humid whether.
PLEASE DO NOT LEAVE YOUR PET IN A CLOSED AUTOMOBILE OR TRUCK – IT MAY LEAD TO TRAGIC CONSEQUENCES!!!
