Heathcliff and the Catillac Cats - Season 1 - Eps 17: Spike's Cousin
Spike's cousin, Bull, is a ferocious looking guard dog who sports a bone out of his mouth the way a tough guy might use a cigar. He convinces Spike that he no longer should take guff from Heathcliff and proceeds to teach him to defend himself but to no avail. After Bull has harassed everyone in the neighborhood, he challenges Heathcliff to a fight in the vacant lot on Elm Street and guess who wins? Who else, Heathcliff!

Synopsis
Heathcliff knows he is the best cat around! Never have we seen such self-confidence topped off with a heavy dose of vanity, cunning, ruthlessness, and a mischievous love of gags. He cruises and struts down the street and watch out any person, cat, or dog who gets in his way! Although he may terrorize the neighborhood, let an outsider try to push anyone around and he is a veritable tiger of defense. On the other side of town are The Catillac Cats, which typically revolve around leader Riff-Raff's get-rich-quick schemes or searches for food.
