My name is Cane!

On Sept 18, I rescued a 18 month old Pitbull after his owners split up. I had a fenced back yard and dog experience. In two months I have learned he did not have regular meals, was allowed to relieve himself inside and had no medical care. I got him seen by my vet, vaccinated and licensed. In two months he has gained 6 pounds weighing 66 lbs now. However, he is always hungry, has learned to go outside but not ask to go out to pee. His exuberance causes him to flail his front legs and scratch or bruise my arms, hand and legs even though I try to block him and give commands to stop jumping. He has had inflammation of his skin twice and is currently on antibiotics and steroids. He is sweet and wants held which I can’t do.
He needs a younger, more active and Pitbull-experienced owner to work with him. I have upcoming surgery which will not be performed if I have unhealed scratches and wounds. He deserves a good life. Neutering is scheduled in December. Help me to help him. I am 76.
