Well if you have the time and desire, Clean Run: Crate Games for Self-Control & Motivation DVD is great. But honestly, I pick puppy up, place them in the crate and shut the door.... no emotion. Some of them throw fits for a while, but the more you fuss over that, the longer it'll last. I would caution against giving edibles at night as you're asking for a potty break or accident in the night.
