Abnormally excessive sweating may be localized or generalized. Causes include pain (colic, laminitis), fever, neurological disease (equine dysautonomia/grass sickness), pheochromocytoma, PPID (Cushing's), hyperthyroidism, toxicosis, and anxiety. Localized sweating may indicate nerve damage (Horner's syndrome causes ipsilateral facial sweating).
Excessive sweating disproportionate to ambient temperature or exercise level; may be patchy or generalized; if associated with grass sickness: sweating with colic signs, dysphagia, muscle tremors; if Horner's syndrome: unilateral facial sweating with miosis and ptosis; persistent sweating at rest warrants veterinary investigation
