What is a common sign of Anhidrosis in horses?

Anhidrosis is a condition that affects a horse's ability to sweat properly, leading to a reduced or complete lack of sweating, particularly in warm weather or after exercise. Therefore, the absence of sweating is a primary and defining characteristic of this condition. Horses with anhidrosis often struggle to regulate their body temperature through normal sweating mechanisms, which can lead to overheating and other health issues.

In contrast, excessive sweating is typically indicative of other conditions or responses, normal sweating is the expected behavior of a healthy horse, and increased thirst may occur for various reasons, but it does not specifically indicate anhidrosis. Understanding the signs of anhidrosis, particularly the absence of sweating, is crucial for the proper management and care of affected horses in both competitive and recreational settings.
