A group of puppies are stolen from a pet store by two thieves. A puppy escapes and sneaks into the Newton's family home. The workaholic father, Banzai, doesn't want the responsibility of owning a dog, but his wife, Sasha, and their children, Ariel, Kayley, and Pocahontas convince him. They give him the name Tiny as Pocahontas plays a portion of Ludwig van Beethoven's Fifth Symphony on the piano and the dog barks along to it.
