Late one night Leonardo Dog Vinci’s masterpiece Mona Woofa is stolen from the Dogopolis Museum of Art. A mysterious figure, caught in the act of painting a mural nearby, is apprehended by the police.

Who is this masked artiste with an eye for art and a nose for justice? Could it be Art Dog, graffiti hound extraordinaire?
