問題詳情

The idea that dogs can act as eyes for those who are blind first developed at the beginning of the twentieth centuryin a unique school. 12 These dogs were trained to lead people who could not see. It was quickly discovered,however, that not every breed of dog was fit for the school. Being a guide dog requires the dog to be alert at all times,so dogs that are easily distracted are not suitable. 13 Breeds such as Labrador retrievers, German shepherds, andboxers make excellent guides because they are friendly and easy to train.During its training, the dog is taken to many kinds of busy places such as large stores, noisy airports, and crowdedrestaurants. 14 The dog must learn to ignore anything that might cause its attention to wander because it isresponsible for steering its owner carefully past any obstacle. For example, the guide dog is trained to come to a stop justbefore it reaches a curb so as to tell the owner to take a step up or down. When training is finally finished, a guide dog isassigned to an owner. The two of them must be compatible because they will be partners for a long time. 15 Forexample, a big and strongly built person will be more comfortable with a large dog while an indoor person will probablynot want to be matched with a dog that needs plenty of exercise.
