Mobility Assistance: Mobility Assistance Dogs perform a variety of tasks for their human partners, like bumping the button on automatic doors, retrieving dropped items, and bringing out-of-reach objects to hand, such as a ringing phone. For dogs that will work with someone in a wheelchair, the animal can assist with pulling a wheelchair up a ramp if necessary. Other dogs may serve as a brace for people who are ambulatory but suffer from balance and strength issues. With a properly retrofitted home, a Mobility Assistance Dog can tug open doors, close them again, turn lights on and off, and summon help by finding another person in the house. In public, the Mobility Assistance Dog is an invaluable helper, quietly serving its partner with tasks that would be difficult or impossible to do on their own. In some instances, these dogs are trained for Laser Designated Retrieval work so the handler can point a laser pen at an item and thereby cue the dog to retrieve that item.
