A service dog must be trained individually, to do specific work assisting his owner, a person with disabilities. His training must have a direct correlation to his handler's disability. The Americans With Disabilities Act specifies that service dogs be allowed to escort their owners in any public place that doesn't allow pets. They are not required to wear an identifying vest, but they must be under their owner's control and on a leash.
Mobility Assistance Dogs
Mobility assistance dogs assist owners who have physical disabilities. They are trained to turn lights off and on, pick up dropped items and pull wheelchairs. They can retrieve items such as remote controllers, phones and medications. Mobility assistance dogs can help their owners get dressed and undressed.
