About the title
A great dane named Marmaduke, charming yet utterly lacking any sense of boundaries, lives happily with his family, unaware that because of him the adults get no peace day or night. While Marmaduke happily poses for nine-year-old Billy, appears in his videos, and hunts the local animals, his owners spend all their free time undoing the damage. But one day they can't take it anymore and send their pet off to be retrained. How will he return to his owners?
