Heat Stroke in Dogs

As the hot days of summer are upon us, the heat can affect our pets as much as it affects us. Heat stroke, also known as HYPERthermia, becomes a concern for dogs on very hot or humid days. It can happen quite quickly – exposure to the heat does not have to be prolonged if the temperature outside is hot enough.

Dogs are unable to deal with heat the same way humans do – they do not have sweat glands (except in their paws) so their body’s main way of cooling is through panting. When panting is not enough, their body temperature can increase rapidly to above 40C. If not treated, heat stroke can even lead to death. Dogs that are brachycephalic (have short noses), are over weight, or have thick fur are at increased risk.

Signs to watch for which tell us that our canine companions are struggling in the heat include excessive panting, bright red gums and tongue, weakness, or even collapse. The dog should be immediately taken to a cooler environment and attempts should be made to lower their body temperature by cooling them with fans, water, or ice. If they have collapsed or are showing signs of weakness, they should be taken to a veterinarian immediately.

Avoid heat stroke by keeping your dog inside on very hot days, avoid taking them for walks or participating in outside activities such as throwing the ball, or wait until the evening when outside temperatures are cool enough to do these things.
