What is heat stroke?

Heat stroke occurs when body temperature becomes elevated to a point where tissue damage occurs. Normally, the body combats elevated temperature through several mechanisms (i.e. panting). In cases of heat stoke, these mechanisms are overwhelmed.

What causes heat stroke?

Heat stroke is more common in dogs than cats. Dogs with underlying conditions may be more susceptible. This includes obesity, respiratory or heart disease and brachycephalic (short-nosed) breeds such as Boston Terriers, Pugs, Pekingese and English Bulldogs. The most common cause of heat stroke is leaving a dog in a car with inadequate ventilation. On a hot day, heat stroke can occur within minutes. Exercise on a hot, humid day can also results in heat stroke. Even an inactive pet left without access to shade is susceptible.

What are the signs of heat stroke?

Pets may pant vigorously and salivate excessively. They may seem restless or, in severe cases, be unable to stand or respond to stimulation.

How is heat stroke treated?

Immediately move the pet to a shaded area with adequate ventilation. Cool the body if possible with cool (not cold or ice) water. Transport the pet to a veterinarian as soon as possible. Some of the results of heat stroke may not be immediately or outwardly visible but can result in life threatening damage.
