Some of the worst dogs in Britain come face to face with three trainers, who will attempt to knock the dogs and their owners into shape with a strong dose of tough love and hard discipline. Alfie is a border collie cross who's a charmer with the ladies but picks a fight with any man he can; Chicho is a Bracco Italiano who can't stop stealing other people's balls; and Dennis and Megan are border terriers who love to attack rabbits.
