Dogs like living with people. A dog can be a very good friend. He can do a lot of things for people. Some dogs help people to look after sheep, other dogs help them to find lost children. And some of the dogs can help the blind (盲人) do things.
Many years ago there was a very good dog. His name was Seeing Eye dog. Now we can see this kind of dogs all over the world. They are working for the blind.
The Seeing Eye dog is strong, good and easy to train(训练). He helps the blind to walk from place to place.
Before a dog becomes a Seeing Eye dog, he must go to a training school for about three months. First the dog has to learn to sit or stay when he hears the trainer’s call. In his next lesson the dog learns to make his trainer across busy streets.
The dog has many things to learn. And in every lesson he must learn to do one thing again and again for many times.
At the end of the training school he must take tests. When he passes the tests, the Seeing Eye dog will do the things by himself.
Now he can help blind people. The new master may be a man, a woman, or even a child. It takes the dog and his blind master about a month to learn to work and live together.
