Archive Case #80: Equine Anhidrosis

Clinical Clues

1. A performance horse in a hot humid environment is struggling with exercise intolerance.
2. The rider reports the horse overheats quickly but produces very little sweat.
3. Recovery after work is prolonged and the respiratory rate stays elevated.
4. The coat remains dry even during heat stress.
5. No infectious or cardiac cause is found to explain the poor performance.
6. Failure of normal sweating in horses leads to heat intolerance and is known as anhidrosis.

Diagnosis

Equine Anhidrosis

This case is most consistent with Equine Anhidrosis because the horse cannot sweat appropriately and develops heat intolerance with exercise. The most important clues are the hot humid setting and dry coat during overheating, which make simple fitness problems less likely.
