Bitzer

Bitzer is one of the main protagonists (sometimes antagonist) in Shaun the Sheep and the secondary deuteragonist in the movie.

Information
the brown, long-suffering sheepdog, only wants a quiet life - but this is the last thing he is going to get when Shaun The Sheep is around. He is obviously on the same side as Shaun and the flock, but even though he is also very loyal to The Farmer, he will never let him know about the animals' intelligence. He somewhat bears a resemblence to Gromit. On "Off the Baa!", he acted referee for the football game, so he probably knows a little football. Bitzer also lets Shaun have the chart and whistle and be in charge if the farmer is sick or something.

Trivia

 * Bitzer can be considered as an antagonist and anti-hero in some episodes.
 * Bitzer's design is very similar to Gromit.
