Crate Training

Q: My puppy loves being in his puppy pen in the TV room, which is one of those foldable metal fences, open on the top. He hates his actual crate, which is a metal cage for dogs, quite large, with plenty of room. I can get him to go quietly into it if I give him a wildly desirable treat. But once the treat is gone, so is his patience for the crate. I try to go in to release him only when he is being quiet, and I'm trying to work up the time he spends in the crate. Also I try to put him in the crate at "sleepy" times. But the crate training is so hard to do emotionally...he yowls! He is lonely and bewildered...he can't be loose in the house, because he chews and eliminates. So we are working on the house-breaking and chew-toy training. He is a whiz at clicker training though, and only 8 weeks old!
