Lady and the Tramp (1955)

Continuity mistake: After Tramp gets his breakfast bone from Tony's Restaurant, he carries it behind a wooden fence and starts chewing. Pretty soon a horse drawn dog pound wagon rolls by, and a worker gets out to nail an impound notice four boards away from him. But when Tramp walks over to read what the notice has to say, it's now nailed six boards from where he was just a moment ago.
