Yes, you can bring a dog on the New York City subway, but only inside a bag or other container. The MTA pets guide says pets on the subway and buses must be "in a bag or other container and carried in a way that doesn't annoy other riders." There is no leash option, however calm your dog is. That one sentence explains the photos of big dogs riding in duffel bags and IKEA totes that keep going around online.
The rule changes as soon as you leave the subway. Metro-North lets a pet ride on a secure leash. The Long Island Rail Road wants a container that fits on your lap. NJ Transit and PATH both expect a carrier, and NYC Ferry now takes dogs on a short leash. If your trip crosses two systems, the stricter rule is the one you need to plan around.
This guide covers all six, using each operator's own wording as we read it in November 2026. We also say where an official page is silent, because a lot of what gets repeated about New York transit and dogs comes from blogs and forum posts, not from the agencies.

The NYC subway rule, and what "container" means
The MTA does not publish a size or weight limit for dogs on the subway, and it does not say what counts as a container beyond "a bag or other container." So there is no 20 pound cutoff, even though you may read one elsewhere. The test in the rule is practical: the dog has to be in something, and you have to carry it in a way that doesn't annoy other riders.
In practice that makes a soft shoulder carrier or a dog backpack the obvious choice for small and medium dogs. Our review of the best dog backpack carriers covers options with proper ventilation and a stiff base. A carrier built for pets is safer than a shopping bag, because your dog can't climb out on a stairway and the bag won't tear under the weight.
What about large dogs? Owners do carry them in big bags, as City and State reported, and enforcement has long been uneven. That doesn't make it a good plan. You have to lift the dog through stations with long staircases and elevators that may be out of service, and a frightened 60 pound dog in a tote is a fall risk for both of you. A loose dog on a platform is worse. If your dog is too big to carry comfortably for several flights of stairs, take a car instead.
MTA buses
The MTA treats buses and the subway the same way, under the same sentence in its guide. Keep the carrier on your lap or at your feet, out of the aisle, and be ready for a crowded bus to get in the way. A driver dealing with a full bus and a barking dog is unlikely to be sympathetic, so try to avoid rush hour.
Long Island Rail Road
The LIRR rule is tighter than the subway's on size. The MTA says your pet "must be in a container that can fit on your lap and be carried in a way that doesn't annoy other riders." A lap-sized container effectively rules out medium and large dogs, which is a real problem for anyone heading out to the Hamptons or Montauk with a bigger dog.
The MTA guide does not list a peak-hour exception, a pet fare or a carrier dimension for the LIRR. If your dog won't fit, the realistic options are driving or a pet taxi. We cover how to pick one in our guide to ground pet transport.
Metro-North: the one with a leash option
Metro-North is the friendliest rail system in the region for bigger dogs. The MTA says your pet must be "carried in a kennel or similar container or securely controlled on a leash throughout the journey" and must not be offensive to other riders.
You will see a claim online that medium and large dogs can only ride off-peak. The MTA guide we read doesn't say that, so we can't confirm it. Even so, off-peak is the sensible choice. A packed rush-hour train from Grand Central leaves no floor space for a large dog, and a dog that bothers other riders breaks the rule. Keep the leash short and your dog on the floor, not on a seat, and keep your dog clear of the doors at stations.
One trap: Grand Central connects to the subway. If you plan to ride Metro-North in with a leashed dog and then hop on the 4, 5 or 6, the subway rule applies the moment you go through the turnstile, so bring a carrier or plan a car for the last leg.
NJ Transit
NJ Transit has the shortest rule of the group, and it covers everything the agency runs. Its FAQ says only service animals with customers with disabilities or their trainers, police dogs, and "small pets in carry-on travel cages" are allowed on its trains, buses and light rail vehicles.
The agency doesn't define "small" there or publish carrier dimensions on that page. Third-party sites list specific measurements and a minimum age, but we couldn't confirm those with NJ Transit, so we aren't repeating them. The FAQ gives no leash option on any of its services. If your dog can't ride in a carry-on sized cage, NJ Transit is not an option.
PATH
The PATH trains between New Jersey and Manhattan run under their own rulebook. The PATH rules and regulations bar anyone from entering with an animal that is not properly confined for shipment. The exceptions are on-duty police and authorized employees, and a person with a disability accompanied by an assistance animal.
The rule doesn't give a size limit. Read it as a closed carrier rule, and don't expect a leash to pass. The version we found lists an effective date of December 20, 2015, so check with PATH if you have a borderline case.
NYC Ferry
NYC Ferry is the exception for dog owners, and its rules have loosened. The current NYC Ferry pet policy allows dogs onboard and at landings if they are well behaved and not disruptive. Keep your dog on a short leash, generally within two feet of you. Dogs must be house-trained and can't sit on seats or block aisles. Other pets need a fully enclosed carrier that fits on your lap or under your seat. Crew can refuse boarding or ask you to leave if these conditions aren't met.
Older pages on the same site still say dogs must be in a carrier or muzzled, so you may see that repeated. We are going by the updated policy page. On a busy summer weekend sailing, ask the crew where they want you to stand before you board.
We could not find a pet rule for the Staten Island Ferry on the official NYC DOT page we checked, so ask staff at the terminal before you plan around it.
Service dogs are different
None of the carrier rules above apply to a trained service animal. The MTA says different policies apply to service animals than to pets, and NJ Transit and PATH both write in exceptions. A dog that only provides comfort is not a service animal under federal law, and an emotional support letter won't get a dog out of a carrier on these systems. Our guide to service dogs, emotional support animals and therapy dogs explains the difference.
Making the ride easier on your dog
Subway noise and crowds are hard on many dogs, so start small. Let your dog eat a meal inside the open carrier at home for a week or so, then carry it around the block, then try one or two stops at a quiet hour. Pick a station with an elevator if you can, and check that it's working before you leave. If your dog pants heavily, trembles or tries to claw out, stop the training and go back a step. Our guides to transporting an anxious dog and crate training for travel have more detail.
Summer needs extra care. Subway platforms get hot, and a closed bag holds heat, so skip the trip on very hot days, or carry water and open the top of the bag once you are seated, keeping your dog secured inside. Go before a meal rather than right after one if your dog tends to get carsick.
A few extras help in any season. Attach a short leash to your dog's harness inside the bag so a sudden jump can't turn into an escape. Carry waste bags and a small towel, and take your dog for a toilet break before you enter the station, since there is nowhere to go once you are inside. Make sure the carrier closes fully and that your dog can breathe easily with it shut. Allow extra time on your first few trips, and be ready to get off a stop early if your dog is struggling.
When transit won't work
Plenty of New York dogs simply don't fit these rules. Your options are a car service that accepts pets, a pet taxi, or a rideshare with a driver who agrees in advance. See our guide to bringing a dog in an Uber or Lyft. For longer trips out of the city, our Amtrak pet policy guide covers the rules on intercity trains. If you are moving rather than making a day trip, a door-to-door pet transporter is usually less stressful than several transfers with a dog in a bag.
Which trip works for which dog
A few common New York trips show how these rules play out. Going from Westchester or Connecticut into Manhattan, a leashed 60 pound dog can legally ride Metro-North to Grand Central. The problem starts at the end of the line, because the subway needs a container. Plan on walking or a pet-friendly car from the station.
Going from Long Island into the city with anything bigger than a lap dog is harder, because the LIRR has no leash option. Most owners of larger dogs drive or book a car. From New Jersey into Manhattan, both NJ Transit and PATH need a carrier, so a large dog is shut out of both. Moving along the East River between Brooklyn, Queens and Manhattan, NYC Ferry is often the best choice for a medium or large dog, since it's the only one of the three systems with a straightforward leash rule for dogs.
If you make a trip like this often, try it once at a quiet time on a weekend before you depend on it. Check the elevators at your stations too, since a heavy carrier on long stairs is the part most owners underestimate.
What happens if you break the rule
Enforcement varies by system and by the day. On the subway, many riders report never being stopped, and others report being told to leave or being given a ticket by police. We couldn't verify a current fine amount from an official MTA source, so we won't quote one. On NYC Ferry, the policy says crew can refuse boarding or ask you to get off. On a commuter train, you are relying on the judgment of the conductor.
The practical point is that being stopped can leave you stranded partway through a trip, with a dog, far from your car. It's not worth the gamble if you have a train to catch or a vet appointment to get to. Cats and other small pets are easier, since all of these systems accept a pet in a closed carrier that fits on your lap.
