Dr. Earl Gaughan said he feels horses manage pain differently depending on the cause of the pain.

In Episode 41 of the Disease Du Jour podcast, we talk about acute vs. chronic pain management in horses for a veterinary audience with Earl Gaughan, DVM, DACVS, an equine professional veterinary services team member at Merck Animal Health. Gaughan graduated from the University of Georgia’s College of Veterinary Medicine and completed his residency in large animal surgery at Cornell University. Gaughan has worked in private equine practice in Maryland and Colorado.

EquiManagement’s Disease Du Jour podcast is focused on equine research and current best practices. Disease Du Jour is brought to you in 2020 by Merck Animal Health.

"I think horses manage pain in two rather distinctly different ways depending on whether pain originates from musculoskeletal tissues and when pain originates from visceral tissues—which I would include ophthalmic tissues in that," said Gaughan. "They seem to manage this pain demonstration quite differently depending on its origin. These are things veterinarians are quite familiar with."
