The dog learns how to move forward and to turn left and right on command. More advanced commands include learning how to stop before crossing a street, leading its blindfolded handler around overhangs or other obstacles safely, and retrieving dropped objects.

Any well trained dog can become a guide dog, although Labrador Retrievers and German Shepherds are the most popular breeds. This is mainly because of their strong instinct to assist their owners. The most important requirement for a guide dog is that it be large enough to be fitted with a harness and a lead. The blind person must be able to reach the lead comfortably.
