When I got my little boy (6 1/2 years ago) he was 6 months old and not trained at all. I tried to train him but he never caught on, so he is always in belly bands. As long as you keep him clean and dry he should be okay. I do crate him while I am at work and he does not mark while in the crate, but without the belly bands I would have every corner and leg of every piece of furniture belonging to him. I use belly bands from
