I have been giving this formula to Petey, my small gray poodle, a 7-year-old and he is now back to being just a kid again. Before taking your product, it was all he could do to get up and down stairs. Actually, he even fell down a short flight as his front legs and shoulders just couldn’t hold him – too much pain. He is now running up and down the stairs, chasing his ball and having a good doggy time once again. It was so hard for me to see my little best friend doing so poorly. Now he’s wonderful once more. Thank You!
