When Phil and Debbie Winslow relocate from their native Kansas to the sunny climes of Orange County, their big-hearted, havoc-wreaking Great Dane gets a taste of the dog's life, California-style.

Great Dane Marmaduke epitomizes the overgrown lapdog, with an irascible streak and a penchant for mischief that is tempered with a deep sense of love and responsibility for his human family, the Winslows. The new animation is set in the world of elite dog shows, rife divas, rivalries and slapstick comedy.
