My Chrissy was suffering from severe arthritis. I tried a bunch of different products and she would not eat them. I went to my Vet and he recommended "Arthogen". He gave me some samples and she ate them like treats. They are a beef and cheese flavor that she likes. I have seen such a turn around in her. She can jump up on the bed and gets up and down the stairs now. (She turns 16 next month!!!) You can find the Arthogen at www.BestPetSupplements.com. They answered all my questions and sent the pills quickly and were cheaper than at the vets office. I hope this helps!
