Dandy is a former street dog, a grown-up rascal and the 'half' member of the team. But he can add some special skills to the group: he can sniff and track, and he can sense danger! He's as intelligent as any human being and he's happy to have the kids look after him because they feed him. He's Fred's best friend and loves him the most, but he would do anything for any of them – even Charly. However, he doesn't like to be commanded and does not obey orders. Well, maybe from Fred.
