As he walked miserably down the deserted street, he heard a dog whimpering quietly. John stopped and looked behind a smelly rubbish bin. He couldn't believe his eyes. Among the rubbish was a small brown and white dog. He looked at the dog's tag to see where it lived. John realised that the house was not far away so he decided to take the dog back to its home. He called the dog and it happily followed him. John soon found the right house and he knocked on the door.
