If the pup is doing it in the kennel I would put a bak collar on it, My pup was horrible in the kennel until I did this and it hasnt affected her on the trail at all, some dogs may be differnt though. I just went to a local pet store and got one for 25 bucks it has held up on my girlfriends dog since mine used it a week and now is quiet in the kennel.
