Notice how Robert rewards the pup, he draws him in a different direction away from the cheese he dropped and treats from the hand. Once the leave it command is solid you can use it for multiple applications, ie; anything you don't want him getting into. My young Mal picked up on it rather quickly, as we have a cat and cats seem like prey to him. It still isn't as solid as I would like but he does direct away from the cat when I tell him leave it.
