Public access · ADA
Two questions. That’s the entire allowed inquiry.
Under the Americans with Disabilities Act, a service dog can go almost anywhere a member of the public can go: restaurants, hotels, stores, hospitals, government offices, taxis, rideshares, gyms. A business is allowed to ask exactly two questions to figure out whether the dog qualifies. After that, they’re done.
Since 1995 we’ve helped tens of thousands of handlers navigate public-access disputes — restaurants, airlines, retailers, rideshares. The recurring pattern: a business that doesn’t understand the rule is the one that creates the friction. We’re going to make sure you understand it cold.
The two questions
A business may ask only these, and only when it’s not obvious that the dog is a service dog:
Question 1
“Is the dog a service animal required because of a disability?”
Yes/no answer. The handler isn’t required to disclose the disability itself.
Question 2
“What work or task has the dog been trained to perform?”
Short answer about a specific task — e.g., “He alerts me to oncoming seizures” or “She interrupts panic attacks.” The handler isn’t required to demonstrate the task.
“Staff are not allowed to request any documentation for the dog, require that the dog demonstrate its task, or inquire about the nature of the person’s disability.”
— DOJ ADA Service Animal FAQ, A6
In plain English:two questions, yes/no answers. No paperwork. No registry lookup. No demo. If a business demands more than that, they’re violating the ADA — and they know it (the rule is on every DOJ technical-assistance document for businesses).
What counts as a “task”
The ADA defines task work as something the dog has beentrainedto do that’s directly tied to the handler’s disability. Comfort and emotional support by themselves don’t count — that’s the line between an ESA and a service dog.
Task examples that do count, by category:
Psychiatric (PSD)
Interrupt panic spirals · Deep-pressure therapy · Medication reminders · Room search before entering · Wake handler from nightmares
Mobility
Brace work · Counterbalance · Retrieve dropped items · Open doors · Turn lights on/off
Guide (low/no vision)
Navigation around obstacles · Targeted destination work · Curb stops · Intelligent disobedience
Seizure (alert + response)
Alert handler before a seizure (predictive) · Stay during event · Fetch help · Position to protect the head
Hearing
Alert to alarms, doorbells, name being called, vehicles approaching, baby crying
Medical assist (catch-all)
Diabetic alert · Cardiac alert · Allergen detection · Narcolepsy response · Autism support
Each category has a full self-training walkthrough at /training/tasks.
When a business can remove a service dog
The ADA isn’t absolute. A business can ask a handler to remove the dog in two specific circumstances:
1. The dog is out of control and the handler cannot regain control.
Out of control means barking repeatedly without cause, lunging at people, jumping on counters, eliminating in the store. A single bark to alert the handler isn’t out-of-control behavior.
2. The dog is not house-broken.
Self-explanatory. A working service dog should never have accidents in public spaces.
Even when the dog is removed, the handler must still be allowed to receive the goods or services. That’s an important detail businesses sometimes miss.
What handlers should know
- Vests, IDs, registries are not required. A business can’t demand any of those. That said, a visible identifier and a verifiable registration like NSAR quietly defuses 90% of pushback before it starts.
- You don’t have to disclose your diagnosis. Just answer the two questions truthfully and move on.
- Cleanliness + behavior matter.A working dog earns the public-access rights every day. Foundational manners (no jumping, no sniffing food, neutral around other animals) are the floor — not extra credit.
- Document violations. If a business refuses you, get a manager name + date + time. The ADA enforcement process starts with a written complaint to ADA.gov.
For business owners + staff
Your staff almost certainly aren’t trying to be jerks about service dogs — they’re trying to be careful about a topic with a lot of misinformation. Here’s the short version, written so a new hire can read it once and get it right:
- Service dogs are allowed in. Default yes — no paperwork, no questions if the work is obvious.
- If you have to ask, ask only the two questions: “Is the dog a service animal because of a disability?” and “What task has it been trained to perform?”
- You cannot ask about the disability, ask for documentation, or ask the dog to demonstrate the task.
- You can ask the handler to remove a dog that’s out of control or not house-broken.
- Allergies and other animals’ fear are not legal grounds to refuse a service dog. (Asthma and similar medical issues for staff are addressed with workplace accommodation, not by removing the customer’s dog.)
