The Only Two Questions a Business Can Legally Ask About Your Service Dog

When you walk into a store, restaurant, or hotel with your service dog, the business staff may not know what they can and cannot ask you. The ADA is very specific about this — and the answer is simpler than most people realize.

The Two Questions

When it is not obvious that a dog is a service animal, a business may ask:

1. "Is this a service animal required because of a disability?"
2. "What work or task has the dog been trained to perform?"

That's it. Those are the only two questions permitted under the ADA. A simple yes to the first question and a brief description of the task to the second is all you're required to provide.

Why Only Two Questions?

The ADA's limits on questioning reflect a careful balance. On one hand, businesses have a legitimate interest in knowing whether an animal is a service dog (so they can comply with the law). On the other, people with disabilities have privacy interests — they shouldn't have to disclose their medical conditions to every business they enter.

The two questions are designed to answer the business's legitimate question (is this dog actually trained to perform tasks?) without requiring disclosure of the underlying disability.

What Businesses Cannot Ask or Require

• Cannot ask: What disability do you have? What is your diagnosis?
• Cannot require: Documentation, ID cards, a vest, certification papers, or a "letter" of any kind
• Cannot require: The dog to demonstrate its task
• Cannot ask: Where did you get the dog? Who trained the dog?
• Cannot charge: Any additional fee because of the service dog's presence

What to Say — Prepare Your Two Answers Before You Need Them

The single most important preparation a service dog handler can do is rehearse a one-sentence answer to each of the two questions, ahead of time, until both come out automatically under stress. Handlers who can answer these two questions calmly and concisely almost never get challenged twice — but in the moment, fumbling for words signals uncertainty that uninformed staff often interpret as evasion.

When asked "Is this a service animal required because of a disability?" — a simple "Yes" is sufficient. You don't owe any further explanation.

When asked "What work or task has the dog been trained to perform?" — be honest and specific. You don't need to disclose your disability. Examples:

• "She's trained to alert me before a seizure"
• "He performs deep pressure therapy when I'm having a panic attack"
• "She guides me — I have low vision"
• "He retrieves dropped items and braces for me when I stand"

If the business asks follow-up questions that go beyond these two, you are within your rights to say: "Under the ADA, those are the only two questions you may ask me."

PawPassRx members get a wallet-sized cheat sheet of these two questions and recommended response phrasing in their account dashboard — designed as a private prep tool to help handlers rehearse a clear, confident response, not something to hand over to challengers.

When a Business Can Remove Your Service Dog

Even a legitimate service animal can be asked to leave if:

• The dog is out of control and the handler doesn't take effective action to control it
• The dog is not housebroken

The business must still give the handler the opportunity to return without the animal.

What This Means for Documentation

Notice: documentation is not on this list of permitted questions. A business cannot require you to show any documentation, ID, or certification for your service dog.

This is why we're clear that our registration and ID products are convenience items — not legal requirements. Many service dog handlers find that having a professional-looking ID card significantly reduces the number of interactions where these questions even come up. But carrying one is your choice, not a legal obligation.

For a deeper read on registration specifically — what it does, what it doesn't, and when it's worth it — see our guide on whether you need to register your service dog. For PSD handlers needing in-cabin air travel rights, the PSD letter is what unlocks ACAA accommodations. For housing accommodations, the ESA letter triggers Fair Housing Act protections.
