 Arthritis type things. I don't have any arthritis at all. And my little dog, Tater, who had some real joint problems and what we both do. Judy does this too. Judy does have a little arthritis, but she does some glucosamine as well. But I do it big time. I take a lot every day. I give Tater and Nellie, my two dogs, I give them more glucosamine than is recommended.
