When Beethoven's lack of social graces gets to be too much for the Newtons, the kids secretly enroll him in an obedience school. A Beethoven-style twist on the tale of the Prince and the Paw-per is unleashed, when during a walk in the park, Beethoven gets loose only to find himself mixed up with Michelangelo, a perfectly-trained dog who looks just like him! While the Newtons can't believe how well-behaved their dog has suddenly become, the real Beethoven wreaks havoc in the home of the rich and snooty Sedgwick family.
