Hi Karen- Personally I disagree with Anonymously on that advice. While its nice that foods contain glucosamine and chondroitin, they don’t contain a theraputic amount. Especially if you have a senior dog that is showing signs of stiff joints. The only time I’ve ever heard of additional supplements causing any of the problems that Anonymously mentioned is when they were overfed. You can certainly still double check with your vet, but most of these supplements are safe to feed along with a food that contains glucosamine and chondroitin.
