Colleen (voiced by Tress Mac Neille) is a fictional anthropomorphic dog from the action/comedy cartoon Road Rovers that premiered in September 1996 on Kids' WB. She is a rough collie from the United Kingdom and the only female in the group. She was a street dog prior to joining the Road Rovers, which serves as a good explanation for her fighting skills, as she is an accomplished martial artist in her humanoid form and, as seen in the first episode, uses a similar fighting style as an ordinary dog.
