Dogs are very lovely animals. They are friendly and honest to people. They are people's good friends. They often help people do many things and people are proud of them.

Dog's bark maybe tells something to people or other animals, and may be a friendly way to say "Hi", Sometimes dogs' bark seems to tell their owners that they have seen some strange people. They will show their teeth when they are sad. They will wag their tails when they are happy.

In one word, they can do all kinds of things to show their friendship. Don't you think they are lovely?
