Yesterday I was returning from school alone. On the way I saw a group of boys around a dog. The dog seemed to be mad, and the boys were throwing stones at it. This made the dog angry and frightened. The dog began to bark angrily. The boys found this very funny and they hit the dog with a stick. I was standing nearby quietly. Suddenly the dog rushed at me and bit me. I shouted to the boys to help me. But they ran away. The dog was so angry that it would not let go of my leg. Finally three men from a nearby shop came out and chased the dog away.
