The players sit in a semicircle facing one child who is the puppy. The puppy is blindfolded and the 'bone' is on the floor in front of them. A 'thief' is chosen by pointing so as not to let the puppy know which direction the thief is coming from to steal it's 'bone'. The thief tries to steal the bone from the puppy without the puppy hearing the thief. The puppy listens, and points in the direction of the thief and barks, if they hear anything. If they catch the thief by pointing at them, the thief has failed and has to go back into the semi-circle. If the thief succeeds in stealing the 'bone' then they become the puppy.
