Most trains allow dogs, but the rules depend on the railroad and your dog's size
You can bring a dog on most passenger trains in the United States, but each railroad sets its own rules about size, crates, and where your dog can sit. Some trains allow small dogs in your lap or at your feet for free. Others require dogs to travel in a carrier, charge a fee, or restrict dogs to certain cars. A few trains do not allow dogs at all except service animals.
The best first step is to contact the specific railroad you plan to use—Amtrak, a commuter rail system in your area, or a regional carrier—and ask about their current dog policy. Policies change, and what works on one line may not work on another. Have your dog's size and whether you have a carrier ready when you call, because the answer often depends on those details.
Key Takeaways
- Amtrak allows dogs on most routes if they stay in a carrier, cost $25 per dog per trip, and cannot travel in dining or sleeping cars.
- Many commuter rail systems allow small dogs for free if they are leashed or in a carrier, but policies vary by region and route.
- Service animals are allowed on all trains without a carrier or fee, regardless of size.
- You must call the railroad directly to confirm the policy for your specific route, because rules differ between lines and sometimes between individual trains on the same line.
- Arriving early and keeping your dog calm in a quiet spot reduces stress for your dog and other passengers.
Amtrak's dog policy and fees
Amtrak allows dogs on most of its routes if the dog travels in a carrier that fits under the seat in front of you. The fee is $25 per dog per trip, and you pay it when you book your ticket or at the station. Dogs cannot travel in the dining car, the lounge car, or sleeping cars, so you must stay in your assigned coach seat with your dog.
The carrier must be small enough to fit in the space under a standard train seat—roughly 18 inches wide, 14 inches deep, and 8 inches tall. Soft-sided carriers work better than hard plastic ones because they compress slightly. If your dog is too large for a carrier, Amtrak does not have an alternative; your dog cannot travel on that route.
Amtrak's website lists which routes allow dogs. Before you book, search for your route and look for the dog icon or check the route details. If you do not see it listed, call Amtrak at 1-800-872-7245 to confirm whether dogs are allowed on that specific train, because the policy can vary by route and season.
Commuter rail and regional train policies
Commuter rail systems—such as those in the Northeast Corridor, the San Francisco Bay Area, Chicago, and other cities—usually allow small dogs for free if they are leashed or in a carrier. Most do not charge a fee. However, the exact rules differ by system and sometimes by individual line within a system.
For example, the Long Island Rail Road allows dogs in carriers on all trains, while the Metro-North Railroad (serving New York and Connecticut) allows leashed dogs in designated cars during off-peak hours. The BART system in the San Francisco Bay Area allows dogs in carriers only. Your local transit agency's website should list the dog policy, but calling ahead is safer because policies update and not all websites are current.
Regional trains that are not part of Amtrak—such as the Downeaster in Maine or the Cascades in the Pacific Northwest—each set their own rules. Contact the railroad directly by phone or email before you book. Have your dog's weight and the dimensions of your carrier ready, because size limits are the most common reason a dog cannot travel.
Service animals and emotional support animals
Service animals are allowed on all trains without a carrier, without a fee, and in all areas of the train, including dining and sleeping cars. A service animal is a dog (or in some cases a miniature horse) that is individually trained to perform a task or do work for a person with a disability. The task must be directly related to the person's disability—for example, guiding a blind passenger, alerting a deaf passenger to sounds, or retrieving items for a person in a wheelchair.
Emotional support animals, comfort animals, and therapy animals are not the same as service animals and do not have the same rights on trains. They are subject to the same carrier and fee rules as any other pet. A letter from a doctor or therapist does not change this. If you have an emotional support animal, treat it as a regular dog when booking train travel.
How to prepare your dog for train travel
Before your trip, take your dog on a short practice ride if possible—even a single commuter rail stop—so your dog becomes used to the noise, motion, and crowded space. Dogs that have never been on a train often become anxious, and a stressed dog makes the trip harder for you and other passengers.
Exercise your dog before boarding so it is calm and tired. A dog that has run or walked for 30 to 45 minutes is much more likely to sleep through the trip than one that is full of energy. Bring water and a collapsible bowl, because trains can be dry and your dog may get thirsty. Do not rely on the train's water fountains.
Pack a small blanket or mat for the carrier or the floor space near your seat. Familiar smells help your dog feel find. Bring waste bags and plan to take your dog outside during stops if the trip is longer than two hours. Some trains have designated pet relief areas at stations; ask the conductor when you board.
What to bring and what to avoid
Bring your dog's leash, collar with ID tags, and a recent photo of your dog in case it gets lost. Pack any medications your dog takes, along with written instructions. Bring treats and a favorite toy to keep your dog occupied, but avoid anything that makes noise or smells strong, because other passengers will notice.
Do not bring a dog that is sick, injured, or showing signs of aggression. Do not let your dog roam the train or approach other passengers without permission. Keep your dog in the carrier or on a short leash at all times. Do not leave your dog unattended, even for a few minutes. If your dog has an accident in the carrier, clean it up when ready and notify the conductor so they can help with the seat.
Avoid peak travel times if you can, because trains are more crowded and your dog will have less space and more stress. Early morning or mid-afternoon trips are usually quieter than rush hour or evening trains.
Booking your ticket and what to expect at the station
When you book your ticket, mention that you are traveling with a dog. If you are booking online, look for a field to add a pet or call the railroad after you book to add your dog to the reservation. Some railroads require you to book by phone if you have a dog, so check the website first.
Arrive at the station at least 30 minutes early. Tell the ticket agent or conductor that you have a dog so they know where to direct you. Some trains have designated pet cars or areas; the conductor can tell you where to sit. Keep your dog calm and quiet while waiting for boarding. Do not let it sniff or interact with other passengers' luggage.
Once on the train, settle into your seat quickly and keep your dog in the carrier or on a short leash. If your dog is anxious, stay calm yourself—dogs pick up on your stress. If your dog becomes disruptive, the conductor may ask you to move to a different car or, in rare cases, to leave the train at the next stop.
Frequently Asked Questions
Can I take my large dog on a train if it is not in a carrier?
On Amtrak, no—dogs must fit in a carrier that goes under the seat. On some commuter rail systems, large dogs may be allowed if they are leashed and well-behaved, but you must check with that specific railroad. Call ahead with your dog's weight and breed to find out whether it can travel without a carrier.
What happens if my dog has an accident on the train?
Clean it up when ready with supplies you bring. Tell the conductor right away so they can note it and help you clean the seat if needed. You may be charged a cleaning fee, though most railroads do not charge if you handle it quickly. Bring extra waste bags and paper towels to be prepared.
Can my dog travel in the sleeping car on Amtrak?
No. Amtrak does not allow dogs in sleeping cars, dining cars, or lounge cars. Your dog must stay in your assigned coach seat in a carrier. If you need a sleeping car, you cannot bring a pet dog on that trip.
Do I need a health certificate or vaccination records for my dog to travel by train?
Most railroads do not require health certificates or proof of vaccination for dogs traveling within the United States. However, if you are traveling across state lines or internationally, some states or countries may have requirements. Check the regulations for your destination state before you travel.
What if the train is full and there is no room for my dog's carrier?
Call the railroad when you book and ask about the expected capacity. If the train is overbooked, the railroad may ask you to take a different train or may not allow your dog on that specific trip. Booking early and calling ahead reduces this risk.
