I give my 12 years GH, Harry, who has Arthritis, a glucosamine/msm and Qi Ye Lian (Herb med, 2-3 tablets twice day) instead of asprin or rimadyl. My holistic vet gave to my bridge GH, Easy, when she had a problem to go to stairs and any kind of pains. It is easy on their GI. You can order from amazon
Good Luck.
Soon, Harry and Cassy
