Every night, a pack of wolves prowled round a field of fat, juicy sheep, licking their hopefully. But every night the farmer's dogs barked to warn their master. One night a wolf crept up to the dogs and said : "This is silly. You're like us, with long noses and tails. The only difference is that you wear collars and obey your master. That's very old- fashioned. Join us, and we can divide these nice fat sheep between us." The dogs scratched their heads thoughtfully, and said " That is a good idea. We'd like some juicy lamb chops." So they let the wolves into the field. The wolves immediately killed all the dogs and then took the sheep for themselves.
