Dogs like living with people. They are very friendly. They can do many things for people. Some dogs help people to look after sheep, other dogs help them to find the lost children. And some of the dogs can help the blind. They are the Seeing Eye Dogs.
Now we can see this kind of dogs all over the world. They work for the blind.
The Seeing Eye dog is strong and easy to train(训练). He helps the blind to walk from place to place. Before a dog becomes a Seeing Eye dog, it 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 take his trainer across busy streets. The dog has many things to learn. At the end of the training school, he must take tests(测试). When it passes the test, it can become the Seeing Eye dog.
The new master(主人) 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.
