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.
Generally, a public accommodation may not make these inquiries about a service animal when it is readily apparent that an animal is trained to do work or
perform tasks for an individual with a disability (e.g., the
dog is observed guiding an individual who is blind or has low vision, pulling a person's wheelchair, or providing
assistance with stability or balance to an individual with an observable
mobility disability).
