Peritonitis in horses — inflammation of the abdominal cavity — is a severe, often life-threatening condition requiring emergency diagnosis and intensive treatment with significant welfare implications.
Equine peritonitis causes extreme pain from peritoneal inflammation and rapidly progressing sepsis. The welfare burden is severe, with affected horses experiencing profound physiological distress and acute pain. Early aggressive pain management, intensive fluid therapy, and prompt antimicrobial treatment are essential welfare priorities alongside diagnostic investigation. Regular pain scoring using validated equine scales guides analgesic adjustments. Where the prognosis is grave and suffering cannot be adequately controlled, timely euthanasia is the most welfare-positive decision.
