27、Welcome to the Guide Dogs Training Center，children．Let me tell you something about guide dogs．（导盲犬）

    In 1918, a doctor and his pet dog walked with a soldier who was blind．l he doctor went in the hospital for a short time．When he came out．he saw his pet had guided the soldier on the other side of the hospital yard safely．So he began to teach a dog to guide people and it worked out well．Germany started a program to train dogs to be guides．

  Dorothy，an American woman，went to Germany to find out about the guide dogs．When she came back to the United States she wrote about it for a magazine．Soon more people knew the guide dogs．The best dogs for the job are clever and fit．It takes more than two years to train a little dog to be a guide dog．When the dog is 14 months old，it learns many instructions，then the owner and the dog meet，and they practice for four weeks．
