I think dogs have been most helpful animal for human being

I think dogs have been most helpful animal for human being also. If we care about them, they obey and they are faithful. When I was small, I had a dog, whenever I had come home, he ran in to me. One day he was injured because he had fought with other dogs, he was not able to move but he walked along with dragging feet and run to me. Dogs are adorable and helpful.

They are very helpful for people who are blind or sometimes they work for police and catch thieves. When disaster strikes, dogs help people from debris.
