Heatstroke is a problem for dogs during summer, especially in hot, humid areas. Dogs that have the greatest problem often have short noses, such as Boston Terriers, Boxers, French Bulldogs, and Pugs. These are called brachycephalic dogs. Brachycephalic dogs have noses so short the air doesn’t have a chance to cool before it hits the lungs and transfers heat to the blood. About half the dogs sick enough to be taken to veterinary hospitals for heatstroke will die.
Dogs with any of the following characteristics or engaged in the following activities are candidates for heatstroke:
- short noses and flat faces (brachycephalic dogs)
- large bodies,
- long-hair,
- overweight, or
- strenuously working or playing.
Dogs that have had a previous episode of heatstroke are more likely to have another episode than dogs that have never had the problem.
