Bandit is the name of Jonny's pet, a small white dog. He has been so named because his eyes have a black, mask-like coloration around them. This coloration is occasionally instrumental in foiling antagonists. He is unique among his fellow Hanna-Barbera dogs (such as Scooby-Doo, Huckleberry Hound, and Hong Kong Phooey), as he is a regular non-anthropomorphic dog. Though, he seems uncannily able to understand human speech and is capable of complex facial expressions. Don Messick provided Bandit's vocal effects, which were combined with an archived clip of an actual dog barking.
