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. In the present day storyline of Pound Puppies and the Legend of Big Paw, he is an adult and shares his past story to his niece and nephew about his story as a child. Voiced by B.J. Ward in both the TV Series and Pound Puppies and The Legend of Big Paw.
