Stop at the bottom and top of stairs until told to proceed
Bring the handler to elevator buttons
Lie quietly when the handler is sitting down
Help the handler to board and move around buses, subways and other forms of public Vehicles
Obey a number of verbal commands
Additionally, a guide dog must know to disobey any command that would put the handler in danger. This ability, called selective disobedience, is perhaps the most amazing thing about guide dogs that they can balance obedience with their own assessment of the situation.
This capacity is extremely important at crosswalks, where the handler and dog must work very closely together to navigate the situation safely. Dogs cannot distinguish the color of traffic lights, so the handler must make the decision of when it is safe to proceed across the road. The handler listens to the flow of traffic to figure out when the light has changed and then gives the command forward. If there is no danger, the dog proceeds across the road in a straight line. If there are cars approaching, the dog waits until the danger is gone and then follows the forward command.
On the Job and After Hours
Guide dogs enjoy their work immensely, and they get a lot of satisfaction from a job well done, but there is no room for typical dog fun during the work day. Games, treats and praise cannot distract the dog from helping its handler navigate the course. Even when the handler doesnt need assistance, a guide dog on the job is trained to ignore distractions and keep still. This is because a guide dog must be able to come to the handlers workplace or be in public places without creating a disturbance.
