以My Pet Dog为题写一篇短文

My Pet Dog I am Li Xiaoming.One day a friend of mine gave me a dog.It is black and from America I love it very much.When it came to my house,it was very small.Now it is bigger.I often play with it and it often follows me everywhere in the house.Sometimes when it sees a stranger come into my house,it will bark out.Sometimes it will wait for me to return.In the evening it will run to wards.It is good to have such a good dog.Now I think it is my friend.
