Bitzer is the long-suffering sheepdog who keeps a watchful eye over his wayward flock. He only wants a quiet life, but this is the last thing he is going to get when Shaun is around. He has tolerant attitude to the sheep’s antics, but is ready to step in if things get seriously out of hand. And if there’s something in it for him, he’ll even join in some of Shaun’s crazy schemes – as long as the Farmer never finds out.
He behaves like a factory foreman, checking the sheep into the field on his clipboard and bringing a flask of tea and sandwiches to work. He often relieves the tedium of his job by listening to his walkman or doing the crossword, which gives Shaun ample opportunity to get up to mischief behind his back. Although Shaun is a source of constant exasperation, the relationship between them is essentially friendly. But ultimately Bitzer’s loyalty lies with the Farmer – he is not going to bite the hand that keeps him in dog food!
