A tough wanders down the street, spits on a brick, splitting it and kicks Fido. His master, Bobby Bumps, demands to know what's going on and gets thrown out of the frame for his trouble. Determining on justice, Bobby goes into training.
Bray's Bobby Bumps was one of the longer-running of the early Bray series and this cartoon shows up in the British Pathe archives from 1922, listed as a "Pen and Inkling".... apparently Pathe's cartoon series. It's adequately produced for 1918, but lacks much in the way of interest. Bobby is simply a middle-class boy and despite an encounter with a black cat by Fido, it doesn't age well.
