One day, a wolf felt very hungry. He wandered here and there in search of food but he could not find anything to eat. At last, he saw a flock of sheep grazing in pasture. He wanted to eat one but they were guarded by a hound. the shepherd's son was also tending the flock vigilantly. The wolf found himself helpless. At last, he hit upon a plan. He hid himself in the skin of a sheep and safely went into the flock. The hounds could not find out the wolf in disguise. He killed the sheep and ate it without being caught. In this way, he ate up many sheep and their numbers began to fall every day. The shepherd was greatly worried but could not find out the thief.
