Friendly reminder that in the United States under ADA service dogs are not legally required to be marked. As a business or organization: to identify a service dog, you can ask the two legal questions (Is this dog a service dog, what tasks does it perform to mitigate your disability)AND if the dog is a disturbance/dangerous you can still request the dog be removed regardless of the answers. You cannot require the dog to be visually labeled as a service dog nor can you legally ask for documentatio
