Animal friends

Now a lot of people like to have some pets. They think pets can bring them fun, but it's not easy to have pets, because it needs lots of time and money to live with a pet. You need to take care of it, and you need to feed it, to play with it and so on.

Some kinds of animals are helpful, such as the police dogs, the guide dogs, the rescue dogs and the pet dogs. The guide dogs can help blind people to find their way, and the rescue dogs can help people to find the people need the help, but the police dogs can help the policemen to find the bad guy who wants to hurt people. Usually the pet dogs are cute, they can let their owner feel happy.
