ADA Title II Action Guide for State and Local Governments

What questions can a public entity ask to determine if a dog is a service animal?

In situations where it is not obvious that a dog is a service animal, a public entity may ask two questions: (1) is the dog a service animal required because of a disability? and (2) what work or task has the dog been trained to perform? Staff may not request documentation of training for the dog, require that the dog demonstrate its task, or inquire about the nature of the person's disability.
