One day I was walking on the road, I met a dog. The dog barked for 3 hours. I bark back at the dog. It chase me, intending to bite me. And I bit it. At first I was a little scared and then I came calm and looked directly at it. It bark again and I asked for help from other people. Finally the dog's owner appeared and took it back to her house. On the second day when I was walking in another street, I saw this dog lying on the road with a lot of injures. I came closer. It recognised me and bark a lot. However, because of bad condition, it could only say some word. I decided to take it to doctor's and it was treated well. The day after when I came back, the dog came straight to me and be friendly to me. I was so happy to have saved it.
