The story of Dede, a famous performing circus dog whose ego is even bigger than her fame. While her circus is moving locations Dede gets left behind and her performing partner (Porter), the Pony in the act, leaves her abandoned to try and steal her limelight for himself.

Billy, a lonely city boy who's just moved to a nearby ranch, discovers her and adopts the vain and arrogant dog. Will she get along with the farm's eccentric critters, including a sleep-deprived rooster, a gassy cow and a hypochondriac horse? And can Dede outwit the bumbling thieves from a rival circus who are plotting to kidnap the priceless pooch?
