Sorry I know I'm always posting. Advice on dogs and food please. He's always begging. And steal some if he gets the chance. He's recently started to love his cage. Doesn't even whine if he's shut in. Until food comes out and he cries and cries. Tried ignoring him in/out of the cage. No difference. When baby is in highchair he knows if he jumps up he goes out of the room for a few minutes. He tries when my back is turned. Any advice?
