Most pages on this subject give you the same four facts: two questions, no registration, dogs only, out-of-control dogs can be removed. All true, all worth knowing, and all available in about ninety seconds on ada.gov.
This page is about the rest of it — the provisions that are in the regulation and almost never quoted, the places where the law says something different from what people believe, and the fifty-state layer sitting on top that changes the answer depending on where you’re standing.
Starting with the one I get asked about most.
Two layers, and they only stack one way
Before anything else, this. It resolves most of the confusion people have about service dog law, and almost nobody states it plainly.
The ADA is a floor, not a ceiling. From the statute itself, 42 U.S.C. § 12201(b):
“Nothing in this chapter shall be construed to invalidate or limit the remedies, rights, and procedures of any Federal law or law of any State or political subdivision of any State or jurisdiction that provides greater or equal protection for the rights of individuals with disabilities than are afforded by this chapter.”
Your state can give you more than the ADA. It cannot give you less.
That single sentence answers a whole category of arguments. A city ordinance that would restrict you further doesn’t win — it offers less protection, so it doesn’t override federal law. A state statute that gives you more — criminal penalties for someone interfering with your dog, access rights for a dog still in training — you get that on top of your ADA rights, not instead of them.
Assistance Dogs International reduces it to a working rule: “check your state’s law and follow the law that offers the most protection.”
Everything below is the federal floor. The state layer comes at the end.
The leash question, and what the regulation really says
This is the one people get wrong most often, including people who are trying hard to get it right.
Here is 28 CFR 35.136(d), in full:
“A service animal shall be under the control of its handler. A service animal shall have a harness, leash, or other tether, unless either the handler is unable because of a disability to use a harness, leash, or other tether, or the use of a harness, leash, or other tether would interfere with the service animal’s safe, effective performance of work or tasks, in which case the service animal must be otherwise under the handler’s control.”
Read the order of those two sentences, because it’s the whole thing.
The first sentence is the requirement. The second is the usual method. Control is what the law demands. A leash is how most teams satisfy it — not what’s being asked for.
And there are two written exceptions, either one of which is enough on its own:
1. The handler can’t use one because of a disability. Someone with no functional grip. Someone whose balance depends on having both hands free or on a rigid mobility handle. The regulation doesn’t ask you to prove hardship — it says unable because of a disability.
2. A leash would interfere with the dog’s safe, effective performance of work or tasks. A dog that has to leave you to do its job can’t do it on a six-foot lead. Retrieving from another room. Fetching a person. Bringing a phone after a fall. Getting between you and a hazard.
In either case the dog must be “otherwise under the handler’s control” — voice, hand signal, or other effective means.
So: is a leash required? Usually yes, by default. But it is not the standard, and stating it as a flat rule — which nearly every page online does — quietly writes the exceptions out of existence for the people who most need them. It’s covered in more depth in is a leash necessary for service dogs.
Where the local leash ordinance comes in
Here’s where the two-layer rule earns its keep.
Almost every town has a leash ordinance. It applies to pet dogs. It does not override a federal exception for a service dog whose handler qualifies for one, because a rule that restricts you further offers less protection, not more — and §12201(b) only preserves state and local law that goes the other way.
That doesn’t mean an animal control officer knows it. It means you’re right, which is a different thing from it being easy.
What I actually do, which is not what the law requires
I’ve been questioned over leashing. So this next part is honest rather than tidy.
Mr. Big worked on a leash, and not because I needed it for control. His obedience and his recall are on point to this day. I very seldom used his harness as a means of control either. I used the leash for a reason that has nothing to do with the ADA:
Public perception. He’s a pit bull cross in their eyes.
A broad-headed dog off-lead in a store is a different animal to the people watching than the same dog on a lead, doing the same work, to the same standard. So I carry the leash. I comply well past what the law asks of me, because the alternative is spending my day in a conversation about my dog’s head shape instead of doing whatever I came out to do.
I’m not telling you that’s the right call. I’m telling you the gap between what the law permits and what a handler actually does is often filled by other people’s assumptions, and pretending otherwise doesn’t help anyone. If you want the legal position on that, it’s in can a pit bull be a service dog.
What “under control” means
Less than people think, and the DOJ has said so.
A dog barking repeatedly in a quiet venue may well be out of control. But per ADA.gov, “if a dog barks just once, or barks because someone has provoked it, this would not mean that the dog is out of control.”
One bark is not a removal. Reacting to being provoked is not a removal. Control means the handler is managing the dog and the dog is responding.
Removal: two grounds, and the half nobody quotes
A business or public entity can require your dog to be removed for exactly two reasons:
- The dog is out of control and the handler does not take effective action to control it
- The dog is not housebroken
That’s the list. Not allergies. Not another customer’s fear. Not a health inspector’s opinion. Not company policy.
And here’s the sentence almost nobody knows exists. If the dog is properly excluded, staff “must still offer their goods or services to the person without the animal present.”
Being told the dog has to go is not the same as being told you have to go. If you’re removed along with your dog, that’s a separate violation on top of the first one. Worth knowing before it happens, because it’s covered in what to do if your service dog is denied access.
The provisions nobody quotes
All straight from 28 CFR 35.136 and the DOJ’s own FAQ. None of them are obscure. They just don’t make it onto the average page.
No surcharge. Ever. A business may not charge you a fee for the dog “even if people accompanied by pets are required to pay fees.” A hotel with a $75 pet fee cannot charge you $75. It can charge you for damage — but only if it charges other guests for damage too.
Nobody else is responsible for your dog. “A public entity is not responsible for the care or supervision of a service animal.” Staff don’t have to walk it, feed it, or hold it. This cuts both ways and it’s worth knowing which way.
Everywhere the public can go. You’re permitted “in all areas” where members of the public are allowed. Not a designated section. Not the patio. Not a back table.
Allergies and fear of dogs are not grounds for exclusion. The remedy is to put the two people in different parts of the room — not to remove the dog.
Religious organizations are exempt from Title III entirely. Churches, and the schools and day care centers they operate. That surprises people, and it’s almost never written down. State law may still apply, which is exactly the sort of thing the state layer is for.
Hospitals: the dog comes to patient rooms, exam rooms and public areas. Operating rooms and sterile units are the limit. If you’re too unwell to supervise the dog, the hospital may arrange boarding — but has to give you a chance to arrange care yourself first.
Restaurants: the dog is allowed. It doesn’t go on a seat or at the table, and it isn’t fed there.
Miniature horses have their own provision, with a different test: type, size and weight against what the facility can accommodate; whether the handler has it under control; whether it’s housebroken; and whether it compromises legitimate safety requirements. Rare, real, and worth knowing it exists.
The registration question, which comes up constantly
I’ve been asked many times for registration papers or a registration number.
There is no such thing in the United States. No federal registry. No national database. No number to give anyone. The regulation is explicit that a covered entity “shall not require documentation, such as proof that the animal has been certified, trained, or licensed as a service animal.”
The two questions are the entire permitted inquiry:
- Is the dog a service animal required because of a disability?
- What work or task has the dog been trained to perform?
That’s it. Not what your disability is. Not for a demonstration of the task. Not for papers. And if the work is obvious — a guide dog in harness leading a blind handler — they aren’t supposed to ask at all.
So most of the time the honest answer to “can I see his registration?” is that you’re now doing unpaid public education. Which is tiring, and is also most of the job.
Worth naming why the confusion exists. Search for service dog law and the first screen of results is thick with sites selling registrations, certificates and ID cards. A business that sells registration has no commercial reason to tell you clearly that registration doesn’t exist — so it says it quietly, once, next to a button that says Register Your Dog. Staff who’ve seen those sites reasonably assume there’s a registry, because a hundred pages implied there was one.
The free version is better, every time. The regulation is at ecfr.gov. The DOJ’s FAQ is at ada.gov. The fifty-state comparison is published free by a university law school. None of them want your card details.
Work is a different world
This one matters and it catches people out badly.
A service dog at your job is not a public access question. Employment runs under ADA Title I, and the rules are not the same.
Per the Great Plains ADA Center, a federally funded ADA National Network center at the University of Missouri:
“Unlike Title II and Title III of the ADA, there are no specific requirements regarding service animals in the ADA employment guidelines.”
Which means:
- The two-question rule does not apply at work. That’s Title II and Title III. It is not employment law.
- Your employer may ask for documentation. “Employers may request documentation to show why the service animal is needed and what it does for the employee” — unless the need is obvious.
- It’s a reasonable accommodation request, assessed case by case, and it can be refused for undue hardship or fundamental alteration.
Why this is worth getting right. A handler who has learned the two questions from twenty websites walks into HR, recites them, and refuses to say more. It doesn’t apply, they look obstructive, and they’ve turned a request that would probably have been granted into a fight.
What worked for me. I told them before I ever considered filling out an application — that I had a service dog, and would that be all right in the workplace. They asked questions, which was reasonable, and I answered them. Big came to work with me. The company liked him so much they issued him his own employee ID card, which I put on his vest.
Asking first is not weakness and it isn’t giving up a right. Employment is a negotiation the law expects you to have. This deserves a page of its own and it’s getting one.
The state layer
Now the part that changes by where you’re standing.
The free, complete, trustworthy source is the Table of State Assistance Animal Laws from the Animal Legal & Historical Center at Michigan State University College of Law. All fifty states, seven categories, nothing for sale.
| Category | What varies | Roughly |
|---|---|---|
| Definitions | Some states define service animal more broadly than the ADA | All 50 |
| Service dogs in training | Public access the ADA does not grant | 49 of 50 |
| Public accommodation | State access statutes layered over the ADA | All 50 |
| Criminal interference or harassment | Penalties for harming or obstructing a working dog | Nearly all |
| Driver duties (white cane laws) | Obligations toward disabled pedestrians | Most |
| Licensing fee exemptions | Waived dog licence fees | About half |
| Fraud and misrepresentation | Penalties for faking a service animal | More than half |
The biggest gap between federal and state law
The ADA gives service dogs in training nothing at all. No public access right, at any stage.
Forty-nine states give them something anyway. Per Michigan State’s table, only Hawaii lacks training-animal protection under its public accommodation law.
If you’ve been told dogs in training have no access rights, that’s true federally and wrong almost everywhere you actually live. The detail is in can service dogs in training go anywhere, which covers what your state actually grants, and to whom
Where the friction actually is
In practice the two state-level things that cause real trouble are leash ordinances and breed laws.
Both are usually municipal rather than state, both are enforced by people who are certain they’re right, and both are situations where the federal position favors you and the person in front of you hasn’t read it. Breed bans, in particular, must make an exception for a service animal — the Justice Department has said so in writing.
The hard part isn’t the law. It’s that being correct and being treated as correct are two different things, and some people would rather defend their rightness than get to correctness. Knowing which paragraph to cite doesn’t always end it. It does mean you’re not the one who’s confused.
Reading your own state’s law without paying anyone
- Start at the Michigan State table and find your state’s row
- Follow it through to your state’s actual statute text, which every state publishes free
- Check your city or county ordinances separately — leash and breed rules usually live there
- Apply the rule: whichever law gives you more protection is the one that governs
If a page wants money before it will tell you what your state’s law says, close it. Your legislature published that statute for free.
And the ADA stops at the border
Worth saying plainly because people are caught out by it. The ADA does not travel. Cross into Canada and your team is assessed under that province’s law, not federal US law — and that is entirely proper, even when it’s inconvenient. Land crossings are usually straightforward, but “usually” is doing work in that sentence. Does the ADA apply in other countries covers what to expect.
Frequently asked questions
Does the ADA require a service dog to be on a leash?
Not exactly. The regulation says a service animal must be under the handler’s control, and that it shall have a harness, leash or other tether unless the handler is unable to use one because of a disability, or the device would interfere with the dog’s safe, effective performance of its work or tasks. In either case the dog must be under control by voice, signal or other effective means. Control is the requirement; a leash is the usual way of meeting it.
Can a business ask for my service dog’s registration or papers?
No. There is no service dog registry in the United States and no federal certification. Staff may ask only two questions: whether the dog is required because of a disability, and what work or task it has been trained to perform. They may not require documentation, proof of certification, an ID card or a vest, and they may not ask what your disability is.
What are the only two reasons a service dog can be removed?
The dog is out of control and the handler does not take effective action to control it, or the dog is not housebroken. Nothing else qualifies. And if a dog is properly excluded, staff must still offer their goods and services to the handler without the dog present.
Can a local leash law override the ADA?
No. Under 42 U.S.C. 12201(b), state and local laws stand only where they give equal or greater protection to people with disabilities. A municipal leash ordinance that would restrict a handler further offers less protection, so it cannot be used to defeat the federal exception. State laws that give you more — such as access for dogs in training — do apply on top of your ADA rights.
Do the ADA’s two questions apply at work?
No. The two-question rule comes from Titles II and III, which cover public entities and public accommodations. Employment is Title I, which has no specific service animal regulations at all. A service dog at work is a reasonable accommodation request, your employer may ask for documentation showing why the animal is needed and what it does, and the request is assessed case by case.
Do service dogs in training have public access rights?
Not under federal law — the ADA grants them nothing. But 49 of 50 states extend some public access protection to dogs in training under their own public accommodation laws, with Hawaii the exception. This is the widest gap between the federal floor and state law, so the answer depends entirely on where you are standing.
Can a business charge a fee for a service dog?
No. A covered entity may not require a surcharge for a service animal even where it charges pet fees. It may charge for damage the dog causes, but only if it charges other customers for damage as well.
Are churches covered by the ADA?
Religious organizations are specifically exempt from Title III of the ADA, including the schools and day care centers they operate. State or local accessibility law may still apply, which is one of the clearest examples of why the state layer is worth checking.
I’m a service dog handler of twelve years, not a lawyer, and nothing here is legal advice. Every legal statement on this page comes from the regulation at 28 CFR 35.136, the ADA statute at 42 U.S.C. 12201, the Department of Justice’s own service animal guidance, the Great Plains ADA Center, or the Animal Legal & Historical Center at Michigan State University College of Law — all linked above, all free to read, and none of them selling anything. If something here is wrong, or if your state does something I’ve missed, tell me and I’ll fix it and note that I did.
