If you can, I'd put up a baby gate to block him from the door. Then you have to reprimand him every time he runs out of the door. You can tap him on the nose w/ a bit of news paper. You should also utilise time out. You can put him in a room if he runs out the door. Or it you have a crate that would work too.
Or if all else fails....you can hold him when you open the door. lol. We have to do that sometimes w/ Mr. Biggs, because lately he's taken to walking out the door to "greet" our visitor. lol |
