S02E20: In The Doghouse

Bitzer's kennel is accidentally destroyed by the farmer's tractor crashing into it and the canny canine hopes the farmer will replace it with a new deluxe model. But when he sees his master's clumsy attempt to build a new kennel, Bitzer is so horrified that he packs his bags and leaves home. Shaun, however, hopes to tempt Bitzer to return with the kennel of his dreams. At the first scene, the flock are having a party at the chicken coop.
