So you get dog bugger snot when it's on it's way out, and doggy skids when it's closing the door! How sweet is that?? Too cool! You should video it!<quoted text>
My son once had a dog that when he told it they were going for a walk, it would go get it's own leash. When I let mine out I leave the door cracked and he pushes it open to get back in and then closes it back. He has learned to back up and bump the door with his butt.
