"The Dog Who Saved Christmas": The Bannister family's new addition, Zeus (voiced by Mario Lopez), a former K-9 police hero, is a less than dependable guard dog; however, when two burglars (led by Dean Cain) aim to break into the family's home while they're away for Christmas Eve, Zeus seizes his chance to be a hero again, proving every dog - even this one - has his day. "The Dog Who Saved Christmas Vacation": Zeus and the Bannister family are back for the holidays! This time, the family must deal with a surprise visit from Uncle Randy (Casper Van Dien), his foxy poodle Bella (voiced by Paris Hilton) and a familiar pair of jewel thieves. Can Zeus solve a crime and save Bella, all in time for Christmas Day? Gary Valentine ("King of Queens") and Elisa Donovan ("Sabrina the Teenage Witch" and "Clueless") co-star in this four-legged family adventure sequel.
