Service Dog Public Access Rules: What Businesses Can Ask

Under the ADA, a service dog may go anywhere the public may go. If it is not obvious what the dog does, staff may ask only two questions: is the dog required because of a disability, and what task is it trained to perform. They may not ask for documentation, and may remove the dog only if it is out of control or not housebroken.
Most access disputes come down to a staff member who does not know the two-question rule. This guide sets out exactly what a business may ask, what it may not, the narrow grounds for exclusion, and how to handle a refusal without escalating.
Where service dogs may go
Any place of public accommodation: shops, restaurants, cafes, bars, hotels, theatres, museums, gyms, hospitals and clinics, government offices, taxis, buses and trains. The dog goes where the handler goes, including areas where pets are prohibited, such as food service areas and hotel rooms.
The dog may not be confined to a particular section, kept away from other customers, or required to wait outside. The handler may not be charged extra or asked to sit in a designated area.
The two questions
When it is not obvious what service the dog provides, staff may ask: Is the dog a service animal required because of a disability? What work or task has the dog been trained to perform?
Those are the only permitted questions. Staff may not ask about the nature or severity of the disability, may not request documentation, certification or proof of training, may not require a special ID or vest, and may not ask the dog to demonstrate the task.
A handler may answer briefly. 'Yes. He is trained to alert me to low blood sugar.' No further explanation is owed.
What staff may not do
Ask for papers. No documentation exists under the ADA and none may be demanded. Charge a fee. Cleaning fees, pet fees, deposits or surcharges may not be applied to a service dog. Actual damage may be charged, as for any customer. Segregate. Handlers may not be seated separately or steered to particular areas. Refuse on allergy or fear grounds. Another customer's allergy or fear of dogs is not a basis for exclusion. The business should accommodate both people, for instance by seating them apart. Handle the dog. Staff may not take the lead or interact with the dog without the handler's consent.When a dog may be excluded
The ADA gives two grounds. The dog is out of control and the handler does not take effective action, or the dog is not housebroken. Out of control means repeated barking in a quiet setting, lunging, jumping on people, or ignoring the handler. A dog that growls once at a sudden noise and is immediately corrected is not out of control.
If a dog is excluded on these grounds, the business must still serve the handler without the dog.
A third ground applies in narrow settings: where the dog's presence would fundamentally alter the service or pose a direct threat. Operating theatres and some zoo enclosures are the standard examples. Ordinary retail and dining do not qualify.
Handling a refusal
State calmly that the dog is a service animal under the ADA and answer the two questions if asked. Request a manager if the staff member persists; managers are more likely to know the rule. Do not argue about documentation, because there is none to produce.
If refused, leave without escalating and record the business, date, time and staff name. Complaints go to the Department of Justice, and many states have their own service animal access laws with local enforcement. Some cities have civil rights offices that act quickly on access complaints.
Misrepresentation
Presenting a pet or an ESA as a service dog to gain access is a misdemeanour in over thirty states, with fines and in some cases community service. It also harms real handlers, because every untrained dog that misbehaves in a shop makes the next refusal more likely. If a dog is not task-trained, it is not a service dog, and no purchased vest or card changes that.
