The Americans With Disabilities Act allows the staff to ask just two questions: Is the dog a service animal, required because of the owner’s disability?

Studies of the potential benefits of animal interactions often take a holistic approach, comparing people's mood or hormone levels before and after spending time with a service animal.

The 4-year-old Brodie is a service animal who is trained to behave well in any circumstances.

If it’s a service animal, the answer is yes.

The owner or handler of the animal is also not required have any kind of identification proving it is a service animal, according to the ADA National Network.
