McDuff, a white Westie dog, befriends a new dog in town, a beautiful French Scottie named Marie-Antoinette. When McDuff and Marie-Antoinette attend obedience school together, McDuff worries that he will embarrass himself because his owners, Fred and Ethel, never practice his lessons with him. Determined to prove himself a star pupil (and hoping to impress Marie-Antoinette in the process), McDuff finds a clever way to learn his lessons without Fred and Ethel`s help.
