RIGHTS & RESPONSIBILITIES
There are only two questions a staffperson can ask you when it's not clear what service the animal provides:
(1) is the dog a service animal required because of a disability
[my answer is "yes"], and
(2) what work or task has the dog been trained to perform
[my answer is "medical alert and assistance"].
[I carry cards to hand out to people with these questions and answers so I don't have to discuss any medical history with a stranger if questioned, though I have not yet been questioned.]
Staff cannot ask about the person’s disability, require medical documentation, require a special identification card or training documentation for the dog, or ask that the dog demonstrate its ability to perform the work or task.
A person with a disability cannot be asked to remove his service animal from the premises unless:
(1) the dog is out of control and the handler does not take effective action to control it or
(2) the dog is not housebroken.
When there is a legitimate reason to ask that a service animal be removed, staff must offer the person with the disability the opportunity to obtain goods or services without the animal’s presence.
Establishments that sell or prepare food must allow service animals in public areas even if state or local health codes prohibit animals on the premises.
NOTE: Providing Food and Water
It might be obvious, but you are responsible for the care and feeding of your dog.Bring water and food with you and remember to provide water often. I've found foldable bowls to be a godsend.
