Whopper (Golden retriever) - Whopper is the youngest of the Pound Puppies. He is often fantasizing and imagining nearly impossible situations, and telling little white lies. He wears a diaper even though he is officially a "kid". Whopper also has a brother-sister relationship with Bright Eyes, as they often share opinions, come to agreements, and experience things together. He also dresses up in many different outfits as alter-egos during a heroic or otherwise serious situation, which is used for comic-relief. Voiced by B.J. Ward.
