Ming our dog, after he's had his setback with his blood count being down, had a limp for about a year, after his blood count came back up. We tried quite a few things to ease his limp. Nothing seemed to help. I came across a pet food, called, far more. It comes frozen, and you have to thaw it, It's got real meat, and vitamines in it, and they said it will make an unwell dog, well. We fed it to him for a month, and his limp is allmost gone. He doesn't like it all that much, so, It takes a fair amount of canniving, to get him to eat it. Go figure.
