My favorte animal

My favorite animal is a dog because there is one verb that says." dogs are humans best friends." I like them very much.
Dog can make us have fun, it's also very useful in our daily life.There are many kinds of dogs, such as rescue dogs, guide dogs and Police dogs.Rescue dogs are used to help fireman to find alive people in ruins.Guide dogs are used to help blind people find their way.Police dogs are used to help Police catch bad people.
