Osteoarthritis is a chronic, non-infectious, progressive disorder affecting the joints of both younger and older dogs and cats. But the clinical signs, including reluctance to perform tasks or activities, are similar regardless of the pet’s age. If left untreated, osteoarthritis can produce an irritable, reclusive, and uncomfortable pet, so it’s important for owners to be aware of its signs, as well as ways to prevent it—or, at least, minimize their pet’s risk–and treat their beloved pets if they do develop the disorder. Dr. William Fortney, assistant professor of diagnostic medicine and pathobiology at the Kansas State University College of Veterinary Medicine, talks about managing arthritis in dogs and cats.
