Bosco

Bosco is the main antagonist in the movie Marmaduke and the former alpha male.

Bio
Bosco first warns Marmaduke in a mean way that he cannot talk, look, or even go near his girlfriend Jezebel. While he is drinking from a fountain he says that Marmaduke is such a Gargantuan Spaz. Marmaduke later that night, comes to the party and accidentally runs into Jezebel which makes Bosco super mad. He then tells him that every pedigree has a unique talent, and mocks that he is only good at sitting and lying down. Then he wanted to fight him, but Jezebel stopped him by saying that he was being a bully.

By accident, even though Bosco is the all-time surf champ Marmaduke bumps into him. For his award not getting earned he got even madder. But Marmaduke uses self-defense and Bosco acts innocent to get him into trouble. Later on, he crashes the party at Marmaduke's house by introducing the cat that lives with Marmaduke. But in the end, Marmaduke becomes the alpha dog and lets everyone (including mutts) sit on the rock. Then a bee lands on his nose, making him terrified for the first time.
