I would let him do it, but not for long periods of time. It seems to make them so happy when they do their little "yorkie dance". My Shadow has LP in both back legs. I'm not sure what grade he is, since the vet only "felt" for it, but as of now, it only bothers him on occassion. I try not to let him jump off the couch/bed, and I bought him those doggie stairs. Also, you could supliment with glucosimine. It's good for the joints. |
