My GSD is ten years old and has Hip Dysplasia and arthritis. She would walk for only a few yards and turn round to go home. My vet put her on NSAIDs which worked, but I wanted to find a safe alternative, and I have. I do not work or have friends or relatives in this company. I just want to pass on something that really does work. Apparently it is the number one seller in America for canine arthritis. DogGonePain is utterly amazing. My sweet dog is now going for walks and enjoying every minute. I just wish there was a human version.
