History of Present Illness

A 5-month-old male Quarter horse kept on pasture is brought to the clinic due to an acute colic episode. The colt had been noticed straining to defecate with increased frequency over the past 6 weeks. As recommended, the owner had been soaking the colt's hay after a veterinarian administered mineral oil by nasogastric tube 1 week prior. The owner had also administered commercial enemas per rectum that had not been recommended by the veterinarian.
