Cliff is one of the show's main antagonists and the macho yet dimwitted commander of the Greaser Dogs. He'll pound you with his cinder-block-like bulldog paw if you look at him improperly. Even if you look him in the eyes, he could pound you. Cliff, on the other hand, has the mental capacity of a box of dog biscuits, which makes him easily outwitted. He is obsessed with thrashing CatDog. Eddie the Squirrel, who desires to be a greaser dog like him, annoys the character constantly. He adores thrashing people and will nearly always succeed in inflicting agony Late episodes show Cliff's gentler aspects, such as his love of ballet and cashmere. Even though he is easily sidetracked, he typically gets his way. Winslow, on the other side, occasionally joins forces with the Greasers to torment CatDog. He received a taste of his own medicine when Eddie became plastered to his jacket, transforming them into "Squirrel Dog." Shriek and Lube booted him out of the Greasers after this happened since he was now a two-headed monster. Cliff experienced the agony of being an outsider, as well as what CatDog went suffered. When he was free of Eddie, he reverted to his old bullying habits and rejoined the Greasers. Cliff even has a niece and nephew, despite siblings never being mentioned.
