Laurent Couëtil, DVM, PhD, professor of large animal internal medicine, director of Purdue University's Equine Sports Medicine Center, has spent majority of his career treating and researching equine asthma. "Milder equine asthma has been difficult to detect because horses don't necessarily show many signs besides the fact they're not performing well," says Dr. Couëtil.
