"Tuffy loves Tim. And Tim loves Tuffy. But Tim also loves Ultra Dog. He watches Ultra Dog on TV. He reads Ultra Dog books. He even has an Ultra Dog cape, sleeps in a bed made with Ultra Dog sheets and wears Ultra Dog underwear. So when Tuffy's next door neighbor, a trouble-making cat named Bosworth, suggests to Tuffy that maybe he should be worried that Ultra Dog is stealing his boy, Tuffy is worried that he might be right -- especially when Tim gets a personal invitation from Ultra Dog inviting him to Ultra Land. So, what's a dog to do?? Fight back, of course! Tuffy decides that if he can't beat Ultra Dog at being a superhero, then he'll have to find another way-like being the best, most obedient dog ever! Or by doing the most chores of any dog, including Ultra Dog. Or by beating Ultra Dog at flying--after all, if Ultra Dog can fly high with one Ultra Dog cape, shouldn't Tuffy be able to fly three times as high if he wears three capes???? But all is well in the end when Tuffy discovers that the invitation to Ultra Land includes him too. To the Dog Star and Beyond!"-- Provided by publisher.
