When Dudley the dog wishes he could eat all of the cakes in the kitchen, he mysteriously switches bodies with his ten-year-old owner, Danny. Danny is now the one who needs to be on his best behaviour, while Dudley is free! But tragedy strikes when Danny and Dudley compete at the local dog show against cruel dog trainer Rex Power and his beautiful pup, Princess Fenella... Danny, the boy stuck in a dog's body, and Dudley, the poor dog who is awful at being human, star in the second canine bodyswap escapade.
