Their only appearance in the film is after Lady runs away after being muzzled by Aunt Sarah. She ends up in the trainyard alley where they reside. The three suddenly emerge, begin chasing, and viciously barking at her. However, Tramp notices what is going on and rushes after the dogs. The strays corner Lady in a dead-end alleyway, but Tramp intervenes and manages to distract and fight off all three of them before they could attack Lady.
