Have you ever seen a person walking along the street with a Seeing Eye dog? It seems that these dogs know what to do. But they certainly do know what they're doing. They do it so well that they people they are with trust them completely. They trust the dogs with their lives. Dogs do more for people than see. There are also dogs that help people hear. People who are deaf can have a dog that is trained to help them. These dogs are trained to hear certain types of noises, like telephones, doorbells, and their owner's name. When they hear these sounds, they go to their owners and lead them to the sound. When they hear a fire alarm, however, they do something quite different. They get their owner's attention and then lie down immediately. This tells the owner that it is time to get out quickly! Dogs are also used to help children with spine injuries and other types of illness. These children, who are usually in wheelchairs, rely on their dogs for many things. The dogs are trained to open and close doors. They can ring doorbells. They can pick up things that the child drops ----- even coins! They can pull the wheelchair, and can go and get help.
It is well known that animals can have a great positive influence on their owners. They make people feel calm and help them live healthier lives. Dogs are used in some hospital environments to help people get better. The dogs make people feel good. They are good friends. There is no doubt that the friendship developed between the working dog and its owner is one of the biggest benefits of all!
