Sometimes it is very helpful for some animals to live with people. And let me tell you a story that happened to me.
My neighborhood is very busy, and I 1 in a tall building. There are ten floors in the building and I am in 2 floor. I have a 3. She is grandma Li. Her 4 goes away so she lives alone. She likes 5 very much. She has a cute dog in her house. She loves it very much and the dog is very 6 to her.
I often visit her when I am 7. Sometimes I play with the dog for a long time and take the dog out for a walk.
Last night, when I was asleep, the dog barked a lot outside my door. So I quickly opened the door. Then I realized there was something 8 with grandma Li. I went to her house quickly. There was a big 9 in the house and grandma Li was insensible (无知觉的). I 10 quickly and then the firemen came. They put out the fire soon and grandma Li was saved.
