The U.S. Food and Drug Administration (FDA) has approved QUEST® PLUS Gel from Zoetis for use in breeding, pregnant and lactating mares.
Anhidrosis is the scientific name for a dysfunction in the ability to sweat. Equine anhidrosis has been recognized for many years, but it’s exact cause is still not known. There does not seem to be any predilection for a particular horse breed, age or coat color, and both male and female horses are affected. Some horses may not be able to sweat at all, and others only sweat in some locations.
