If you live in a city and own a small dog or cat, you've probably wondered: can I actually take my pet on the subway? The short answer is yes — but there's a catch. Almost every US transit system requires your pet to be fully enclosed in a carrier. No loose dogs, no heads poking out of backpacks, no exceptions (unless your pet is a service animal).
Here's the complete breakdown of pet rules for every major US subway system in 2026, plus what to look for in a carrier that makes city travel actually enjoyable for both of you.
NYC Subway (MTA) — Most Flexible Policy
New York City has the most famous (and most relaxed) subway pet policy in the country. The MTA rule is simple: your pet must be in a carrier or container that prevents it from being a nuisance to other riders.
What makes NYC unique is that the MTA doesn't specify a size limit for the carrier or even the dog — which is why New Yorkers famously stuff large dogs into IKEA bags just to meet the technical requirement. In practice, most enforcement is casual, and small dogs and cats in soft-sided tote carriers sail through with zero issues.
NYC MTA rules at a glance:
- Pet must be fully enclosed in a carrier or container
- No size limit for dog or carrier specified
- Carrier must be manageable by one person
- Pet must not disturb other riders
- Service animals are always exempt
- No additional fee
Chicago (CTA) — Small Pets in Closed Carriers
The Chicago Transit Authority permits small pets on buses and trains, but is more specific than the MTA: your carrier must be closed, designed for pet travel, and fit under a seat or on your lap. The emphasis on fitting on your lap or under the seat means compact, well-designed carriers are the way to go.
CTA rules at a glance:
- Small pets only in a closed protective carrier
- Carrier must fit under seat or on lap
- Must be carried by one person
- No fee
San Francisco BART — Enclosed Carrier Required
BART (Bay Area Rapid Transit) follows a clear rule: all pets — including emotional support animals — must travel in a secure, enclosed carrier they cannot escape from. Unlike NYC, ESAs receive no exception here and must be bagged like any other pet.
BART rules at a glance:
- Secure enclosed carrier required for all non-service pets
- ESAs are not exempt
- Pet must not disturb other passengers
Washington DC Metro (WMATA) — Carrier Required
The DC Metro allows pets in carriers on Metrorail and Metrobus. The key requirement: your pet must be in a container it cannot escape from. Soft-sided canvas carriers with a drawstring closure or secure top button are perfectly acceptable here.
DC Metro rules at a glance:
- Secure carrier required — pet must not be able to escape
- Applies to both Metrorail and Metrobus
- Must not disturb other riders
Los Angeles Metro — Hard Carrier Preferred
LA Metro is the strictest of the bunch. While pets are allowed on all bus and rail lines at no charge, the official policy specifies a hard carrier that passengers must be able to carry at all times. If you're traveling in LA, a sturdy structured carrier is the safest bet to avoid any issues.
LA Metro rules at a glance:
- Hard carrier preferred per official policy
- Must be carried at all times — no rolling carriers left on the floor
- No additional fee
What Every City Has in Common
Regardless of where you are, US transit systems all agree on a few things:
- Your pet must be contained. No exceptions for leashed walking pets on platforms or trains.
- Your carrier must be manageable. One person, one carrier, one hand free to swipe your MetroCard.
- Your pet must not bother other riders. Barking, jumping, or escaping will get you removed.
- Service animals are always welcome. No carrier required for a working service dog.
What Makes a Good Subway Pet Carrier?
Not all carriers are created equal when it comes to city transit. Here's what actually matters:
Secure closure — no escape artists
The single most important feature. Your carrier needs a top that stays shut even if your pet pushes against it. A drawstring top combined with a button closure gives you two layers of security — and keeps your pet's head safely inside when the train jolts.
A peek opening for curious pets
Pets who can see what's happening around them are significantly calmer than pets in fully sealed carriers. A controlled peek opening — one your pet can look through but not escape from — makes the whole experience less stressful for both of you. It's also, let's be honest, unbearably cute, which makes your commute more enjoyable too.
Shoulder or crossbody carry
Subway life means turnstiles, stairs, and standing in crowded cars. A carrier you can wear across your body keeps your hands free, distributes the weight, and keeps your pet close to you. Handheld carriers get tiring fast on longer commutes.
Breathable fabric
Subway platforms in summer can hit 100°F. Canvas is your best friend here — it's lightweight, breathable, and doesn't trap heat the way synthetic materials can. Your pet stays comfortable even during long platform waits.
Built-in safety tether
Even if your carrier closes perfectly, a safety clip that attaches to your pet's collar inside the bag gives you peace of mind. If the bag shifts or opens unexpectedly, your pet isn't going anywhere.
The GraviPaw Canvas Pet Shoulder Tote: Built for the Subway
The GraviPaw Canvas Pet Shoulder Tote checks every single box on that list. Designed specifically with subway travel in mind, it features:
- A peek-head opening with adjustable drawstring — your pet can look out, but can't get out
- A top button closure for double security
- A built-in safety buckle that clips to your pet's collar
- Both shoulder and crossbody carry options, so you can switch based on platform vs. train
- Breathable canvas construction that stays cool and lightweight

It comes in two sizes: L (38×38 cm, suitable for pets up to 3 kg dogs / 4 kg cats) and XL (45×45 cm, for pets up to 6 kg dogs / 8 kg cats). That covers the vast majority of subway-friendly small breeds and cats.
Whether you're hopping the R train in Brooklyn, catching the Red Line in Chicago, or riding BART through the Bay, this carrier meets the enclosed pet requirements of every major US transit system — and looks good doing it.
Tips for a Stress-Free Subway Ride with Your Pet
Practice at home first. Let your pet spend time in the carrier at home before your first subway trip. Feed them treats inside it. Make it their safe space before it becomes their transit space.
Travel off-peak when possible. Crowded rush-hour trains are overwhelming for pets. If you can take the 10am train instead of the 8am, your pet (and everyone around you) will thank you.
Bring a familiar scent. A small blanket or toy from home tucked into the carrier helps keep anxious pets calm. Familiar smells reduce stress significantly in new environments.
Keep the peek opening at your pet's level. Position the carrier so your pet can actually see out at a comfortable height. Pets that can observe their surroundings generally stay calmer than those in complete darkness.
Check the rules before you go. Transit policies do occasionally update. Always check the official transit website for the city you're in before your trip — especially if you're visiting rather than a local.
