Dog Health: Heat Stroke

Dog | Heat Stroke

An Introduction to Heat Stroke

As the temperatures warm up over spring and summer, many of us are keen to get outdoors and enjoy the better weather with our dogs.  However, it’s important to be aware that dogs can easily suffer from heat stroke during the warmer months.

Heat stroke occurs when a dog becomes so overheated that his/her bodily tissues become damaged. This is obviously a more serious condition than just getting too warm (eg.  Increased panting, wanting to rest, feeling thirsty).  However, it doesn’t take long for a dog to progress from being a little too warm, to experiencing heat stroke.  Heat stroke can result in very serious organ damage that may or may not be reversible with treatment.  Heat stroke can also result in death.

It doesn’t take very long at all, for a dog to heat stroke – for example, a dog can die within minutes if left in a hot car without shade and adequate ventilation.  On a warm day, a closed up car can act like an oven!
