Different people keep different pets.Someone likes catys,someone prefers birds.But my favorite anmial is a dog.I have a black dog,He looks small and like a wolf cub.I like him very much.I have great fun playing with him.And I often take him out for a walk after my school.He is so clever that he can even return home by himself after we play for a long time.Bones and meat are his favorite food.He is also clean and strong because he always runs to the river to swim and take a bath in summer.He is my best friend.
