Bang, Bang is a cute trick and is easy to teach if your baby already knows down. While they are in the down position, move the treat from the side of the head to the rear and slightly over their back. You are trying to get them to roll over. When the roll over, say "Bang, Bang", and point your finger like a gun. Give them the treat while they are on their backs. Maggie likes this game. She would rather play Bang, Bang than any other trick. I too think you should wait until after Puppy School to continue tricks. You wouldn't want your baby to be the Class Clown, and get suspended.
