Colic is the leading cause of death in horses and causes significant acute suffering. Rapid recognition and appropriate veterinary intervention are critical for minimizing welfare impacts.
Equine colic welfare is determined by the severity of pain involved, the speed of diagnosis and treatment, and the outcomes achieved. Mild spasmodic colic causes temporary pain that resolves rapidly. Severe surgical colic involving displacement or volvulus causes extreme acute pain that ranks among the most severe conditions in veterinary medicine. Horses with severe colic show rolling, looking at their flanks, kicking at their abdomen, and other signs of intense distress. Rapid veterinary assessment is essential — delaying treatment worsens outcomes and extends suffering. Post-surgical recovery has its own welfare challenges. Euthanasia is sometimes the most welfare-appropriate outcome for severe cases where prognosis is poor or financial constraints prevent surgery.
