养狗好处多，你家里养狗了吗？
Dogs are people’s best friends. They are great for any family. When you have a dog, you need to walk them every day. This gives you some exercise. If you have kids, a dog can help teach them to be more responsible (负责任的). A dog also keeps your home safe. They often sleep by the door and make loud noise if things are wrong.
