I hope to get Stella into the vet on Monday when I call. She is now limping with every step she takes, even on her front legs. Some think she has arthritis. Feeling her stomach I fear she also has a tumor. I have been giving her this supplement for years for her hips. I could see a major difference when I started but now wonder if it makes any difference at all. Her smiles are normal, she wags her tail, her appetite is normal and water intake. One day in the backyard grass she even tried trotting a short distance. One of the vets at the new place I plan on taking all of my dogs, specializes in older dogs with these types of issues and treating with alternative methods. I don't want her to spend the rest of her life living on prednisone.
