Last winter I was very busy with my lessons and came home very late every day.However，no matter how late I went home，my dog used to stand at a comer near my school waiting for me. When I passed there，he barked two or three times then ran towards me. It seemed that he was calling me.
　　My dog not only，took good care of me，but also was respoasible at home. When strangers came to my house，he barked at them but not hurt them. What a lovely dog he is！
