Glucosamine and chondroitin, as well as MSM and Boswellia, are commonly used to treat arthritis (degenerative joint disease) and related pain in dogs and cats with worn cartilage. But be careful! Our recent tests revealed that one popular pet supplement contained only about three-quarters of its listed glucosamine and chondroitin. Another had so little glucosamine and chondroitin as to possibly have no benefit. Fortunately, we also discovered higher quality products that delivered what they claimed — significant doses of potentially beneficial ingredients. Among these, those providing the best value were selected as our Top Picks for dogs and cats.
