Horse Colic: Emergency Recognition and Welfare

Colic is the leading cause of death in horses and causes significant suffering. Rapid owner recognition and appropriate emergency response saves lives.

Key Facts

Colic refers to abdominal pain in horses from any cause — from gas accumulation to life-threatening bowel displacement
Clinical signs include pawing, looking at flanks, repeated lying down, sweating, and reluctance to move
Simple impaction colic resolves with medical treatment in most cases; surgical colic requires rapid referral
The decision to refer for surgery must be made quickly — delay reduces survival and increases suffering
Large colon displacement and small intestinal strangulation are life-threatening surgical emergencies
Pain assessment and monitoring are critical to distinguish medical from surgical cases

Welfare Considerations

Colic is one of the most painful conditions horses experience. The visceral pain from intestinal distension, ischemia, or displacement causes extreme distress that is clearly visible in the horse's behavior. Without pain relief, a horse with severe surgical colic suffers intensely. The welfare imperative is rapid veterinary assessment and analgesia, followed by honest decision-making about medical versus surgical management and, ultimately, euthanasia if surgery is not pursued or fails.

What You Can Do

Call your vet immediately at the first signs of colic — do not wait to see if it resolves
Do not administer oral medications without veterinary guidance as they may mask diagnostic signs
Note the time signs began, any changes in behavior, and whether the horse has defecated
Walk the horse gently if it is trying to lie down and roll — gentle movement reduces gas accumulation
Follow your vet's advice on referral — delaying surgery for financial reasons causes suffering
Discuss your decision-making framework for colic (including financial limits and surgery thresholds) with your vet before an emergency occurs
