It sounds like your dog may be experiencing muscle atrophy (shrinkage). This occurs with disuse, myositis (muscle inflammation), nerve disease, or cancer. This dog needs to be examined by a veterinarian to diagnose this condition.

Thanks. I did that yesterday and that is what they said. Thank for the help
