Dehydration is a serious problem in competing and working horses, especially during hot weather. Horses are very sweaty animals and can quickly become dehydrated.
Horses competing in endurance racing or engaging in sustained heavy exercise are at the highest risk of dehydration.
Dehydration occurs when your horse loses excessive fluids from sweat, urine, feces, and respiration. If your horse does not drink enough to offset the fluid loss, she can become dehydrated.
The most common signs of dehydration are poor performance, loss of skin elasticity, weakness and increased respiratory rate. Dehydration also increases the risk of heat stroke, tying-up and slow exercise recovery.
Knowing the signs of dehydration and how to help keep your horse hydrated is important for every horse owner.
