Mr. Spacely assigns George to be the judge for the annual Spacely Space Sprockets Space Dog Show. But this leads to a very stressful situation for him as his family wants him to make Astro the winner, as well as the boss wanting him to insure his wife's poodle comes out on top, and even a mobster named Mangler Mars gets into the act by making George choose his bulldog, Starbite, as the top dog. What choice will George make? In the end, Mrs. Spacely's pooch gets taken away to give birth to puppies; Starbite is revealed to be a stolen dog which gets the mobsters arrested; and Astro wins, with a stray dog winning a consolation prize: dog food.
