Many people like keeping animals as pets. But it is not easy to do. It takes you lots of time and money.

Animals are very helpful. For example, police dog can help the police to catch some bad men. And rescue dog can save people. The Seeing Eye dog can help blind people. What a clever and brave dog! What about pet dogs? They are cute. They can make us happy. Some old people have no relatives, so if they have pets, they will not feel lonely.

I think animals are all friendly. We must protect them, because they are our friends.
