Description:  The "Heathcliff and Marmaduke" cartoon features two distinct animated characters: Heathcliff, a mischievous orange cat from a comic strip, and Marmaduke, a large, clumsy Great Dane from a different comic strip. The two characters have separate adventures, though they sometimes team up. Heathcliff's cartoons often involve him outsmarting neighborhood bullies and causing trouble, while Marmaduke's episodes tend to feature him causing mayhem through his size and clumsiness.

Heathcliff: A cunning orange cat known for getting into trouble and outsmarting bullies in the neighborhood.

Marmaduke: A very large and clumsy Great Dane whose antics often lead to humorous situations.

Structure: The show originally featured two separate cartoon segments, one for each character, in each episode.

Themes: The episodes explore themes like friendship and overcoming challenges. While Heathcliff resorts to a "slapstick" level of violence to deal with bullies, he doesn't initiate it.
