Dr Joseph J. Bertone presented “Sleep Disorders in Horses: A Review and Classification of 420 Cases” at the June forum of the American College of Veterinary Internal Medicine in Denver. Afterward, he spoke with JAVMA News.
He saw his first case three decades ago when he was a resident working toward becoming an ACVIM diplomate in large animal internal medicine. A horse with severe weight loss came in for a workup and kept collapsing in the stall. The veterinarians found and removed a staple that had migrated from the colon into the diaphragm and two enteroliths. The horse was in good condition at a recheck three months later.
