Colic means abdominal pain and ranges from mild to immediately life-threatening. A horse that merely becomes quiet and stops eating may need help as urgently as one that rolls. Call your vet as soon as you suspect colic.
Recognise changes
Look for reduced appetite or droppings, flank-watching, pawing, repeated lying down, sweating, altered breathing or an unusual posture. Report when signs started, the last feed and manure, and recent changes in food, medication, exercise or housing.
While waiting
Follow veterinary instructions. Do not give oil, laxatives or human medication. Gentle walking is only appropriate when advised and safe; do not exhaust the horse. Prevent injury without putting yourself between a distressed horse and a wall.
