anhidrosis

Horses can lose several gallons of sweat per hour during intense exercise, making electrolyte replacement important after hard work.

Anhidrosis, the inability to sweat, is a condition that sometimes affects horses living in hot, humid climates.

Without the ability to cool through evaporation, affected horses are at serious risk of overheating.

Horses can develop allergies to pollens, molds, dust, and certain feeds.
