How to Treat Arthritis in Dogs: Glucosamine, Chondroitin Sulfate, NSAIDs, and More
Glucosamine, chondroitin sulfate, and other nutritional supplements are widely used to treat dogs with arthritis. The reason is simple: Arthritis will afflict most dogs as they age. Unfortunately, dog owners and veterinarians rarely notice the early warning signs of arthritis because dogs tend to hide soreness and discomfort until the arthritic changes in joints have become severe.
But before we discuss glucosamine and chondroitin sulfate and their effect on arthritis, it is important to note that no nutritional supplement will correct structural damage to a dog's joints (this is true in humans as well). If there are calcium deposits, scar tissue, missing or torn cartilage, or changes to the bones at the joint surface, these abnormalities will remain present and will continue to affect the animal regardless of nutritional intake.
