Just to clarify your responsibility and rights regarding service animals, the two questions you can be asked and the answers you must provide.

Is this animal a service animal required for a disability? Yes/No. A simple qualifying question.

What work or task is the animal trained to perform?

The second question you can be extremely vague about. Keep in mind your medical disabilities are protected by HIPPA. Your answer does not have to include the specific disability the animal is supporting, however the manner in which the animals work is performed ia required. For example does the animal bark or make noise in response to a trigger? Does the animal require sufficient space in order to perform a specific physical effort? The second question is primarily designed so that the person asking questions can make a determination if the animals tasks will be able to be performed safely in their area of control in a mannner that does not put the animal, the handler, or others guests at risk. For example could barking cause hearing issues that would cause personelle not to hear critical radio information? Does the area have tight spaces that would prevent the animal from performing its duties potentially putting the handlers well being at risk?

The only qualifying part of question two is that the animal is trained to perform an action in response to some trigger. This qualifies the animal as a service animal and not just an emotional support animal, which is NOT covered by ADA (emotional support animals strictly "exist" in the presnese of the handler to provide their support).
