I assume from your post you are crating him while you are out? How long time period is that for then? Personally I hate crates and have never had a reason for using them but if it's the way you are going with your pup you have to restrict the length for time he's shut in it and make sure the time he's out of it he's stimulated mentally and physically. I think for a young dog 2 hours is more than enough time locked in a cage. Is there a reason he cannot have free run in one room of your house? Just imagine yourself being enclosed in a small area for a length of time, and then when you are released told off for being full of energy? He can't be blamed for being glad of being free?
