We see a working dog a beggars dog a shepherds dog and a milkmans dog The working dog is locked inside a large wire wheel the dog runs inside the wheel turning it to run a machine The beggars dog pulls its legless master whos sitting on a low cart down the street The shepherds dog keeps a flock of at least 20 sheep in a tight circle The milkmans dog pulls a cart on which is mounted a large cylinder of milk A lad leads the dog to a house with a Dutch door the top half of the door opens and the lady of the house hands out a pitcher that the boy fills as the dog waits
