Guide dogs play an important role in preserving the independence of the visually impaired. There are over 11 million visually impaired people in the US, but only about 10,000 use guide dogs. Guide dogs allow many to live independently. The document provides 5 rules for interacting with guide dogs: do not distract working guide dogs, never feed a guide dog, it's okay to ask for identification proving a dog is a certified service animal, do not try to steer a blind person with a guide dog, and help out by opening doors or reading menus.
