Service Dog on a Bus or Train: Amtrak, Greyhound and City Bus Rules

A service dog can ride Amtrak, Greyhound and any city bus in the United States, and it rides free. No driver or conductor may demand paperwork for the dog, and none may ask what your disability is. That part is simple.

What is not simple is that buses and trains run on a different rulebook from the one you know. The rules in a shop or restaurant come from the Department of Justice. The rules on a plane come from the Air Carrier Access Act. Buses and trains sit under a third set, written by the Department of Transportation, and it differs from the other two in ways that matter when a driver is standing in the doorway.

Mr. Big and I have ridden city buses a few times and never had a problem with a driver.

I have never taken him on Amtrak or Greyhound, so those sections are built from the carriers’ own published policies and the federal record, not from my trips. Where I am telling you something from experience, I will say so.

The short answer

Which rulebook you are standing in

There is a line in my flying with a large service dog piece that I keep coming back to: knowing which building you are standing in tells you which rule applies. Ground travel is the third building. A cruise ship is a fourth, with its own federal rule, which I cover in taking a service dog on a cruise ship.

In a shop, restaurant, hotel or government office, the rules are the Department of Justice’s, and they are laid out in the ADA service dog laws. A service animal is a dog, with a separate provision for miniature horses.

On a plane, it is the Air Carrier Access Act and 14 CFR Part 382. Dogs only, and the airline may require two Department of Transportation forms.

On a bus or a train, it is the Department of Transportation’s ADA rule, 49 CFR Part 37. One sentence in it covers the city bus, Amtrak and Greyhound alike. Section 37.167 opens with “This section applies to public and private entities,” and paragraph (d) says:

“The entity shall permit service animals to accompany individuals with disabilities in vehicles and facilities.”

That is the whole right, and it applies whether the bus belongs to your city or to a private company.

The Justice Department’s own regulation steps aside here. Its Title II rule for state and local government says that public transportation covered by the transportation part of the ADA is “not subject to the requirements of this part.” So the rule a transit driver answers to is DOT’s, not the one you may have read for shops.

The definition is wider than you expect

In 2010 the Justice Department narrowed its definition of a service animal to dogs. The Department of Transportation did not follow. Its definition, in 49 CFR 37.3, still reads:

“Service animal means any guide dog, signal dog, or other animal individually trained to work or perform tasks for an individual with a disability.”

The Federal Transit Administration told transit agencies plainly at the time: “These changes to DOJ’s regs do not affect the DOT ADA regulations, which cover transportation (both public and privately-operated).” It also told them not to change their policies because of the DOJ rule.

For almost everyone reading this, it changes nothing, because your service animal is a dog. It is worth knowing for one reason: it tells you that the rules on a bus are genuinely a different set, and that a driver quoting you the restaurant rule may simply be quoting the wrong book.

Amtrak and “dogs only”: three documents, three answers

I found one place where this gets muddled, and I am going to show it rather than resolve it.

Amtrak’s own service animal page describes a service animal only by what it does. It names no species. The federal rule says “or other animal.” But the Oregon Department of Transportation’s rider guide for Amtrak Cascades says: “Effective June 2024, Amtrak will no longer accept species other than dogs as service animals.”

That is a mismatch in the framework, and I am going to leave it as one. If your service animal is a dog, none of it touches you.

What a driver or conductor may ask, and what they may not

The Federal Transit Administration’s guidance to transit agencies is short enough to memorize:

“A transit provider may ask if an animal is a service animal or ask what tasks the animal has been trained to perform, but cannot require special ID cards for the animal or ask about the person’s disability.”

Two questions. Is it a service animal. What is it trained to do. That is the same pair you get in a shop, which is the one place the rulebooks line up.

What they may not do:

• Demand a card, a certificate, a vest or a registration. None of those is required by federal law, and the regulator says a transit provider “cannot require special ID cards.”
• Ask what your disability is. Also in that same sentence.
• Charge extra for the dog. 49 CFR 37.5(d): an entity “shall not impose special charges, not authorized by this part, on individuals with disabilities.” Nothing in that part authorizes a charge for a service animal.
• Limit you to one animal. The FTA’s answer to that question starts with “No.”
• Refuse you because another passenger is allergic. The FTA’s answer to riders with allergies is blunt: “Encountering cigarette smoke, service animals, and other potential allergens is a function of going out in public.”

The dog can be excluded in two situations only: it is out of control and you do not take effective action to control it, or it poses a direct threat to someone’s health or safety. A dog lunging at passengers can be put off a bus. A dog lying at your feet cannot. If you want the longer version of what “control” means, it is in is a leash necessary for service dogs.

The card that got a bus driver corrected in writing

In September 2013 a bus operator in Richmond, Virginia, refused to let a passenger board with a diabetic alert dog and demanded “a special card.” When the passenger pushed back, the operator ordered them off and a supervisor backed the operator up.

The passenger complained to the Federal Transit Administration. FTA’s letter, complaint 14-0090, called the treatment “regrettable and inconsistent with DOT ADA regulatory requirements” and stated the rule without any wiggle room:

“Transit agencies cannot require riders to provide documentation for their service animal, but may ask riders whether animals are service animals and what task(s) they perform.”

The agency retrained its staff. That letter is worth more than any card anyone will sell you, because it is the regulator saying out loud that the card is not required. The industry that sells registrations and ID cards is selling an answer to a question drivers are not allowed to ask. More on that in how to identify a fake service dog.

ADA information cards: good to have on hand when it gets difficult

Having just said nobody can demand a card, here is the one card I do think is worth carrying, and the difference matters.

A registration card or an ID claims to prove something about your dog. It proves nothing, and no driver may ask for it. An ADA information card does something else entirely: it puts the law in the other person’s hand. It is a handout, not a credential.

On a bus that difference is practical. You do not get ten minutes to explain federal regulations at the front door with a line of people behind you. You get about thirty seconds. A driver who has been told the wrong thing by a coworker is not going to take your word for it, but is far more likely to read a small card, because then they are not being corrected by you, they are reading the rule. That is when circumstances turn problematic: the driver who is sure dogs are not allowed, the conductor who wants papers, the supervisor who backs them up. That is what the card is for.

Hand it over when the conversation stalls, not as your opening move. Leading with a card invites the idea that you think a card is required, and you do not.

One honest note. The cards quote the Justice Department’s wording, which is the shop-and-restaurant rulebook. On a bus or train the regulator is different, but its guidance says the same two things the card says: two questions, and no paperwork. A driver who reads it will come away with the right answer.

Amtrak: the ride is easy, the relief is the whole problem

Amtrak’s policy is clear and, for the most part, generous. Service animals are “permitted in all areas where passengers are allowed,” and the pets page adds: “Service animals are not considered pets, and are welcome on all Amtrak services.”

What Amtrak says, in its own words:

• Questions: “Amtrak personnel may ask what active task(s) the service animal performs.” No documentation is mentioned anywhere on the page.
• Booking: “Passenger may include their service animal on their reservation during booking by completing the booking questionnaire.” May, not must.
• Where the dog goes: “A service animal must sit under the passenger’s seat or at his or her feet. Service animals are not allowed to sit in the aisle, on seats or on beds.” That “on beds” is the only sleeper-car rule I could find.
• Large dogs: “Contact us at 1-800-USA-RAIL or email for accommodations such as accessible seating space for large service animals, if necessary and available.” If your dog is the size of mine, make that call before you travel, not at the platform.
• Emotional support animals: “An emotional support animal is not a service animal under DOT regulations and is subject to the same requirements as a pet.”

Where does the dog relieve himself on a train?

This is the question that decides whether an Amtrak trip works, and the answer is: at a station, if the schedule allows, and nowhere else.

Amtrak requires a service animal to be housebroken, “trained to wait to relieve themselves at appropriate station stops—and not onboard.” Then it closes the obvious workaround:

“Not permitted: Litter boxes, animal pee pads, diapers, non-waterproof carriers, and other containers, bags, and packs to facilitate animal relief onboard.”

I wrote in the flying piece that Mr. Big is house-trained, not pee-pad trained, and that asking a house-trained dog to go on a tiled floor indoors is asking him to do the one thing you spent years teaching him never to do. On Amtrak you do not even get the option. The dog holds it until a stop.

So the stops are the plan:

• “If you plan to walk your animal during the trip, please notify the conductor when you first board the train.”
• “Conductors can provide information about station stops that provide sufficient time for the handler to walk the animal to a relief area.”
• “If the train schedule permits, you may walk your service animal at station stops provided that you stay within reasonable proximity to the train and re-board promptly when the conductor notifies you that the train is about to depart.”
• “Some routes may have limited or no stops for the duration of your trip, so we encourage you to check schedules before you make your travel plans.”
• And the extreme case: “For the Auto Train, there is only one stop in Florence, SC, which is a service stop that may be used as a station relief stop.”

Amtrak does not publish a list of which stops are long enough, and I am not going to invent one. What I would do is look at the timetable before booking, find the longest scheduled stops on the route, and ask the conductor at boarding which ones will actually give you time. Plan the dog’s food and water around those stops, not around the clock.

If the trip crosses into Canada, the dog’s paperwork for the border is a separate question from Amtrak’s rules. That side of it is in traveling internationally with a service dog.

Greyhound and the other intercity bus lines

Greyhound’s rules page puts it bluntly: “We don’t let animals on board (not even Greyhound puppies). The only exception is legitimate service animals riding together with a disabled person.”

Its disabilities page adds the detail:

“Service animals must remain on the floor within your personal space which is the area around your feet. Service animals may not occupy a seat, sit in a customer’s lap or protrude out into the aisle.”

Greyhound’s definition includes “psychiatric service dog” by name and “other animal individually trained,” which matches the federal rule. Its tariff says a service animal travels “at no additional charge.” For relief, Greyhound says its buses “make frequent scheduled stops,” which on a long route is a real advantage over a train.

FlixBus, which owns Greyhound, says for North America that “no advance notice is required,” that service animals are “transported at no additional charge,” and that “these animals are not required to wear a muzzle.” It allows the dog on your lap or at your feet, but not on a seat.

Megabus has one line worth knowing if you ride express routes: “If you are a disabled customer traveling on a bus without a handicap accessible restroom making an express run of three hours or more without a rest stop, and you are unable to use the inaccessible restroom, you may request an unscheduled rest stop.” It is written about the passenger’s needs rather than the dog’s, but it is worth knowing before a long express run.

One line veterans should read twice

FlixBus’s own support page says: “Emotional Support Animals (ESAs) including therapy, PTSD, comfort animals are also allowed to travel.”

A dog trained to perform tasks for PTSD is a service animal, not an emotional support animal. The difference is training, not diagnosis. I am not suggesting anyone at FlixBus means harm by that sentence, but a driver who reads it may file your dog in the wrong category. If that happens, the answer is the second question: here is the task he is trained to perform. What those tasks actually look like is in what PTSD service dogs do.

When a bus line’s terms ask for more than the rules allow

Most bus lines get this right. A few smaller ones publish terms that go further than federal guidance allows, and I would rather you read them here than at the boarding door.

• Wanda Coach’s terms say: “Passengers must provide legal documentation with a photo to prove that the animal is a service animal.” There is no such document in federal law.
• Coach USA’s ShortLine page says: “Exception: Service animals properly certified will be transported.” There is no federal certification. The same page lists “emotional support animal” inside its definition of a service animal.
• OurBus’s help page says a passenger may have to buy an additional ticket depending on the animal’s size or the space it needs. I could not find any federal rule that allows a charge for a service animal, and the one I quoted above bars special charges.

I am not calling anyone a name. I am putting the carrier’s own sentence beside the regulator’s and letting you read both. If you ride one of these lines, carry the FTA sentence on your phone and the information card in your pocket.

The federal government is already looking at this

On 4 August 2025, the Justice Department opened an investigation into Flix North America, FlixBus and Greyhound under Title III of the ADA. The allegations it named include that the companies “refused to allow service animals to accompany passengers with disabilities or improperly asked for documentation.”

That is an investigation, not a finding. Nothing has been proven, and I could find no outcome posted as of September 2026. But it tells you two things. Refusals on intercity buses are common enough to reach the Justice Department. And the complaint you file is part of the record an investigation is built from.

One passenger’s account made the news the year before. In August 2024, CBS Pittsburgh reported that Steven Gailey, whose dog Neal alerts him to seizures, said Greyhound refused to let him board with Neal, and that he had been questioned about the dog on several trips. In his words, the steward “wanted to know why I had him” and “what he did for me and he wanted to know what was wrong with me.” Asking what the dog does is allowed. Asking what is wrong with you is the question the rules say nobody may ask.

City buses and paratransit

This is the part I can speak to from experience, and my experience is boring, which is the point. Mr. Big and I rode city buses a few times and never had a problem with a driver. We got on, we rode, we got off. Most rides go like that. The refusals are real and they make the news, but they are not the typical day, and I do not want this article to make you afraid to try.

Buses were part of how I got him ready, too: on and off them, along with everything else, for months. As I wrote in the public access test, airports and buses are where public access gets tested hardest, with crowds you cannot leave and noise you cannot control. If your dog is going to ride regularly, practice getting on and off before the day it matters.

What your local agency may add is detail, not permission. The Texas systems show how much they vary:

• DART (Dallas): “No permit is required, but you may be asked to confirm that your animal is a service animal.” The dog “must remain at your feet or on your lap” and “may not sit on a vehicle seat.” DART’s code of conduct also allows an animal “in training to assist a person with a disability.”
• Houston METRO: “Service animals are always welcome on METRO vehicles and in METRO stations during all hours of service. The service animal should be kept out of the aisles as much as possible and under your control at all times.”
• CapMetro (Austin): bans everything that is not a service animal: “pets, emotional support or comfort animals are not allowed.” Its accessibility page says service animals “must ride underneath the seat and shouldn’t block the aisle,” which is not realistic for a large dog. If yours does not fit under a seat, the floor at your feet and out of the aisle is the reasonable reading.

Paratransit: tell them when you book

If you use your city’s paratransit service, the one extra step is at booking. Agencies may ask you to say you are bringing a service animal so the right vehicle and space are sent. Atlanta’s MARTA puts it this way: “On MARTA Mobility riders must inform reservations that they will be traveling with a service animal in order to help ensure adequate space is available for the animal.” That is about space, not permission.

What a refusal at the bus door looks like

In June 2015, Patch reported that Daniel Wright, a combat veteran whose service dog helps him with PTSD, said he was put off an NJ Transit bus in Newark. The driver told him, “You can’t bring dogs on the bus,” and when he said it was a service dog, “I don’t care.” NJ Transit’s response was the right one: “Service animals are permitted on rail, light rail and other vehicles within NJ Transit… There are no exceptions to that rule.”

The rule was never the problem. The driver was. That is the case the information card is for, and the case the complaint process below is for.

Emotional support animals and dogs in training

Emotional support animals are not service animals under the transportation rule. The FTA says transit agencies “are only required to allow service animals.” Beyond that it is the carrier’s choice. Amtrak treats an ESA as a pet (dogs and cats only, a 20-pound limit including the carrier, trips up to seven hours on most routes). Greyhound allows no animals except service animals. Most of the city systems I checked allow a pet or ESA only in a closed carrier, and CapMetro does not allow them at all. The full difference between the two is in emotional support animal vs service dog.

Dogs in training are a patchwork, and I am not going to pretend otherwise. The federal rule covers animals that are “individually trained.” It says nothing about dogs still in training. Amtrak lists “animals in training” among the animals passengers “shall not misrepresent” as service animals, so a dog in training rides under Amtrak’s pet rules, if it fits them at all. DART in Dallas allows dogs in training by name. Your state may give trainers rights of its own. How that works state by state is in can service dogs in training go anywhere.

When it goes wrong: where the complaint goes

The rulebook is different on a bus or train, so the complaint goes somewhere different too. Here is the map.

Before anything else, write it down. The FTA asks for “specifics such as dates, times, and route numbers of incidents.” Get the route, the bus or train number, the time, and the driver’s or conductor’s name or badge number if you can. If it happens more than once, keep a log. The FTA says it gives priority to repeated problems over single incidents, so a pattern carries weight.

City bus, light rail, subway or paratransit

Complain to the transit agency first; every agency is required to have a complaint process. If it does not fix it, go to the Federal Transit Administration: the online civil rights complaint form, (888) 446-4511, or FTA.ADAAssistance@dot.gov. “Complaints should be filed within 180 days of the alleged violation.” Know what FTA is and is not: “We do not represent individual complainants.” It makes the agency fix the problem. The Richmond case above is what that looks like.

Amtrak

Complain to Amtrak, and also to the Federal Railroad Administration’s Office of Civil Rights: civil.rights@dot.gov or 202-493-0669. FRA analyzes the complaint, works with the railroad toward a voluntary fix, and can refer it to the Justice Department. It is honest about its limits: “The FRA cannot order a rail provider to pay monetary damages.”

Greyhound and other private bus lines

Complain to the company. Greyhound’s ADA address is ADA.support@greyhound.com, and it says its ADA compliance specialist “generally completes an investigation within 30 days from the receipt of the complaint.” Then file with the Federal Motor Carrier Safety Administration at 1-888-DOT-SAFT (1-888-368-7238), 8 a.m. to 8 p.m. Eastern, Monday to Friday, or online through its National Consumer Complaint Database. FMCSA says you can file about “any bus company violation of the Americans with Disabilities Act.” And file with the Justice Department at ada.gov/file-a-complaint or 1-800-514-0301 (TTY 1-833-610-1264). That is the office running the FlixBus and Greyhound investigation.

Your state

Federal agencies can make a carrier change. They mostly cannot pay you. Money, where it exists, comes from state law, and most states have their own statute layered over the ADA. Texas is one. Human Resources Code § 121.003(b) says no “common carrier, airplane, railroad train, motor bus, streetcar, boat, or other public conveyance or mode of transportation” may refuse a passenger because of their disability, or charge extra “because of his or her use of a service animal.” What that is worth in practice, and what it is not, I went through in what to do when an Uber driver refuses your service dog, which is the same problem one step earlier, at the curb before the station.

Before you go: a short checklist

• Relief first. On a train, find the long stops on the timetable and tell the conductor at boarding. On a bus, know roughly where the scheduled stops are.
• Big dog? Call Amtrak on 1-800-USA-RAIL about accessible seating space before the trip.
• Paratransit? Say “service animal” when you book.
• Two answers ready. Yes, he is a service dog. And the task, in one sentence.
• An information card in your pocket for the day a driver will not listen.
• The complaint route saved on your phone for the carrier you are riding.

Frequently asked questions

Can a service dog ride Amtrak?

Yes. Amtrak says service animals are permitted in all areas where passengers are allowed, are not pets, and are welcome on all Amtrak services. Staff may ask what task the animal performs. The dog must stay under your seat or at your feet, not on seats, beds or in the aisle, and must wait to relieve itself at station stops, because pee pads and litter boxes are not allowed on board.

Can a service dog ride a Greyhound bus?

Yes. Greyhound bans all animals except service animals, which travel at no additional charge. The dog must stay on the floor in the space around your feet and may not sit on a seat, on your lap or in the aisle. Greyhound’s definition includes psychiatric service dogs by name.

Can a bus driver ask for my service dog’s papers?

No. The Federal Transit Administration says a transit provider may ask whether the animal is a service animal and what tasks it is trained to perform, but cannot require special ID cards or ask about your disability. In a 2014 complaint, FTA told a Virginia transit agency that demanding a card from a rider with a diabetic alert dog was inconsistent with federal rules.

Do I have to pay extra for my service dog on a bus or train?

No. The federal transportation rule, 49 CFR 37.5(d), bars special charges on people with disabilities, and nothing in it authorizes a charge for a service animal. Greyhound and FlixBus both state that service animals ride at no additional charge, and Amtrak lists no charge for them and says they are not pets. If a smaller bus line’s terms say otherwise, I could find no federal rule that allows it.

Are emotional support animals allowed on Amtrak or Greyhound?

Not as service animals. Amtrak treats an emotional support animal as a pet, which means dogs and cats only, a 20-pound limit including the carrier, trips of up to seven hours on most routes, and a fee. Greyhound does not allow any animals other than service animals. City transit systems set their own rules, usually a closed carrier.

Can a service dog in training ride the bus or train?

It depends on the carrier. The federal rule covers animals that are individually trained and does not mention dogs in training. Amtrak treats a dog in training as a pet. Some city systems, including DART in Dallas, allow dogs in training by name. State laws may add rights for trainers, so check your state as well as the carrier.

Where does my service dog sit on a bus or train?

On the floor at your feet, out of the aisle. Amtrak says under your seat or at your feet. Greyhound says the floor in the area around your feet. A few carriers, like FlixBus and DART, also allow a small dog on your lap. None allow the dog on a seat. On Amtrak, ask about accessible seating space for a large dog before you travel.

What if another passenger is allergic to my dog?

Another rider’s allergy is not a reason to refuse your dog. The Federal Transit Administration’s answer to riders with allergies is that encountering cigarette smoke, service animals and other potential allergens is a function of going out in public. A driver may be able to help by seating people apart, but the allergy is not grounds to put you off.

Where do I report a service dog refusal on a bus or train?

For a city bus or train, the transit agency first, then the Federal Transit Administration within 180 days. For Amtrak, Amtrak and the Federal Railroad Administration’s Office of Civil Rights. For Greyhound and other private bus lines, the company, the Federal Motor Carrier Safety Administration and the Justice Department. Your state may also have its own law and agency.

Does the Air Carrier Access Act cover trains and buses?

No. The Air Carrier Access Act covers airlines only. Buses and trains are covered by the Department of Transportation’s ADA rule, 49 CFR Part 37, which has no forms, allows no documentation demands, and still defines a service animal as any animal individually trained to do work or perform tasks for a person with a disability.

Should I carry an ADA information card on a bus or train?

It is not required, and no driver may ask for one. But a small card that quotes the access rules is useful when a driver or conductor will not listen, because they can read the rule instead of arguing with you. Keep it as a handout for when the conversation stalls, not an opening move, and never confuse it with a registration or ID card.

This article is general information from one service dog handler, not legal advice. On buses and trains the rules come from the Department of Transportation’s ADA regulation; shops and restaurants, air travel and housing are governed by different rules, and state protections vary. Carrier policies change, so check the carrier’s own page before you travel. For your situation, contact the ADA Information Line on 800-514-0301 or a disability rights organization in your state.
