Pet Spotlight    dots    Dogs and Heat Stroke




Dogs are more susceptible to heat stroke than humans are. Never, ever leave a dog in a parked car or in the sun or without water! Read on for signs, prevention and more.

Contrary to what most people believe, dogs overheat more quickly than humans do. They wear their fur coat all year long and they do not sweat. They cool their bodies by panting, or blowing out heat, which is much less effective than sweating. Even if you are comfortable, your dog may be too hot!


Heat stroke happens when heat gain exceeds the body's ability to dissipate heat. High temperatures cause chemical reactions that break down body cells which lead to dehydration andblood thickening. This puts extreme strain on the heart and causes blood clotting and subsequent death to tissue. Liver, brain and intestinal cells are usually the first to be affected and this can occur quickly. Normal body temperature for a dog is about 101 F to 102 F. If his temperature reaches 106 F, he is in danger of brain damage, vital organ failure and death. Reducing body temp quickly is imperative. A dog who recovers can still have organ damage and lifelong health problems. Temperatures above 106 F are extremely dangerous.
