Thanks All
Comic is a chubby boy because he was born with out a hip socket and so one leg is held by the muscle only when his tendon snapped 3 years ago. He is also 13 1/2 years old.
He has lost hair on his tail and butt because he drags himself on the carpet sometimes. Still he is always excited to go for a walk and will run after a squirrel if he sees one. We keep him on Rimadyl everyday for pain control. As long as he is still we are happy. Mya has actually been good for him. He seems perky now for an old dog.
