Getting Mad at my Dad

My dad gives me what he eats, and always gives me attention when I want it from him. But when he doesn't I pee on his side of the bed. He gets mad at me and I get in trouble for it. So he tries to give me more attention and food so I don't get mad. Just the other night he was playing his guitar and I tried to lay in the guitar case, and he got me out. After he left the room I peed on the bed and I got in trouble. What should I do about this and can anyone help me?
