Monitor your pup when he isn't in the crate. If you are playing with him on the floor and he starts to look for a place to potty, pick him up without hesitation and take him outside. Don't scold; he'll associate scolding with eliminating, complicating your training. For the first week, keep the crate in your bedroom for nighttime sleeping. A young puppy may need to go out a couple of times during the night. Don't play with him during these events. Let him do his business, then praise him and take him back to his crate. If he has trouble sleeping during those first nights, wrap a wind-up clock in a towel and place it in the crate with him.
