Tips on how to prevent heat stroke in horses, and the signs to watch out for.

Heat stroke (also known as heat exhaustion or hyperthermia) is very dangerous in animals, and in some severe cases can be fatal. When horses are performing excessive amounts of work in very hot or humid weather, the horse is unable to lose body heat causing its body temperature to go up rapidly.

Not only can a horse get heat stroke when doing exercise, but on very hot days a horse’s body temperature can rise when in the field or stable. Stables are usually made from wood and so can heat up very quickly. Although it may seem like the best idea to get the horse out of the sun, it can be far hotter in a stable, giving the horse no way of escaping the heat. The ideal situation would be to turn the horse out in a field with lots of shelter, i.e. trees or a field shelter. This will allow the horse to access the shade to get out of the sun.

Below is a list of symptoms, treatments and tips to prevent heat stroke in your horse/pony.

Symptoms:

• Restlessness/lethargy
• Panicky/manic
• Increased sweating
• Heavy breathing/Rapid pulse

Treatment:

As quickly as possible:

• Cold water to the skin/poured over the horse’s body
• Add ice to water in severe cases of heat stroke
• Fan the horse and take to a shady area

Prevention:

• Avoid prolonged or intense periods of exercise
• Avoid the hottest times of the day
• Remove all tack as quickly as possible
• Wet the whole horse with plenty of cold water
• Walk your horse lightly whilst cooling to aid circulation
