You've seen the photos. A massive Alaskan Malamute sitting calmly inside a blue IKEA bag with leg holes cut out. A fluffy Samoyed peering out of a hiking backpack like a confused astronaut. It’s the kind of stuff that goes viral on TikTok every three months because, honestly, it looks ridiculous. But if you live in NYC, the new york subway dog bag isn't a meme. It’s a survival tactic. It’s the difference between getting to the vet in 15 minutes for $2.90 or spending $60 on an Uber Pet that might cancel on you twice.
The MTA’s Section 1050.9 is famously vague. It says "no person may bring any animal on or into any conveyance or facility unless enclosed in a container and carried in a manner which would not annoy other passengers." That’s it. That is the whole rule. It doesn't specify the weight of the dog. It doesn't define what a "container" is. It doesn't say your dog's tail can't be sticking out.
Because the rules are so loose, the "container" has become a canvas for New Yorker creativity.
The Reality of the Enclosed Rule
Most people think there's a 20-pound limit. There isn't. If you can carry a 75-pound Golden Retriever in a specialized duffel bag without hitting anyone, you are technically—according to the letter of the law—within your rights. But "technically" is a dangerous word when you're facing a grumpy NYPD officer at the Bedford Ave station.
I’ve seen people get away with a Chihuahua in a tote bag. I've also seen people get turned away because their Pitbull’s head was poking out of a backpack. The enforcement is wildly inconsistent. It depends on the day, the officer, and how crowded the L train is.
Why the IKEA bag became the gold standard
The blue IKEA FRAKTA bag is the unofficial mascot of the new york subway dog bag movement. It costs about a dollar. It’s nearly indestructible. Most importantly, it’s huge.

Back in 2017, a photo of a dog in an IKEA bag went nuclear on Reddit. It showed the world that "enclosed" is a flexible concept. People started cutting holes in the bottom for legs, allowing the dog to stand naturally while the bag hung from the owner's shoulders. It’s a loophole. It works because the bag technically surrounds the dog’s torso. However, the MTA has occasionally clarified that the animal must be fully contained. If the paws are touching the ground through holes in the bag, you’re looking at a fine. The dog has to be carried.
Choosing the Right Gear for Your Dog’s Size
Small dogs have it easy. You can throw a 10-pound Yorkie into a stylish Wild One carrier or a basic mesh bag from Amazon and nobody blinks. It’s the "big dog" owners who have to do the heavy lifting. Literally.
If you have a dog over 40 pounds, a standard shoulder bag is going to destroy your back. You need a K9 Sport Sack. These are specifically designed backpacks that keep the dog in a vertical, seated position on your back. They have safety straps, cooling mesh, and actual lumbar support.
The weight factor
Don't lie to yourself about your fitness level. Carrying a 50-pound Labrador in a new york subway dog bag while navigating the stairs at Union Square is an Olympic-level feat. The station elevators are notoriously broken. If you can’t deadlift your dog and hold it for a 20-minute standing ride on a shaky 4 train, the bag strategy isn't for you.
- Small Dogs (Under 15 lbs): Any tote with a firm bottom works.
- Medium Dogs (15–35 lbs): Look for cross-body slings or structured backpacks.
- Large Dogs (40+ lbs): The K9 Sport Sack Rover is basically the only safe option.
The Unspoken Social Contract
Living in New York is about not being an annoyance. The "annoy other passengers" part of the MTA rule is the one that actually gets people in trouble. If your dog is in a bag but barking its head off, you’re going to get kicked out. If your dog's tail is whipping a commuter in the face, expect a confrontation.

Training your dog to love the bag is the step everyone skips. You can't just shove a confused animal into a backpack for the first time on a loud, screeching subway platform. That’s a recipe for a panic attack—for both of you.
Start at home. Put the bag on the floor. Toss in some high-value treats (think freeze-dried liver or plain chicken). Let them climb in. Do this for a week before you ever head toward a turnstile. You want your dog to see the new york subway dog bag as a mobile safe space, not a nylon prison.
When to skip the subway
There are times when the bag just isn't the move.
- Rush Hour: Between 8:00 AM and 10:00 AM, the trains are packed. Space is at a premium. Bringing a bulky backpack with a dog inside is a jerk move.
- Heat Waves: Most subway stations aren't climate-controlled. If it’s 95 degrees outside, it’s 110 on the platform. Your dog, trapped in a bag against your body heat, can overheat in minutes.
- Wet Weather: A wet dog in a bag smells. It just does. Your fellow commuters will not appreciate the musk of damp fur in a confined space.
Legal Risks and Fines
Let’s talk about the $25 fine. That’s the standard ticket for an "uncontained" animal. While it’s not a huge amount of money, the real headache is being forced to leave the station. If you're halfway to an appointment and a cop stops you at 42nd Street, your day is ruined.
There is a weird grey area with service animals. Under the ADA, service dogs do not need to be in a bag. However, "emotional support animals" (ESAs) do not have the same protections in the NYC subway. If your dog is an ESA, it still has to follow the bag rule. Don't be the person who buys a fake "Service Dog" vest online to avoid using a new york subway dog bag. It’s disrespectful to people with actual service animals and transit workers see right through it.

Dealing with the NYPD
If an officer approaches you, be polite. Don't argue about the "semantics" of the word enclosed. If they tell you the bag isn't sufficient, just leave the station. Most of the time, if the dog is calm and the bag looks secure, they’ll leave you alone. They have bigger things to worry about than a Corgi in a backpack.
Practical Steps for Transit Success
Before you head down those stairs, run through this checklist.
First, check your gear. Are the zippers reinforced? I’ve seen a bag zipper burst open on a moving Q train. It was chaos. Use carabiners to "lock" your zippers together if your dog is a squirmer.
Second, map your route. Aim for stations with elevators if you have a heavy dog, but always have a backup plan for when that elevator is "Out of Service." Use the MTA app to check real-time updates.
Third, bring a "distraction kit." A chew toy or a lick mat can keep a dog occupied during a long delay between stations. If the train gets stuck under the East River for 15 minutes, you’ll be glad you have it.
Actionable Next Steps:
- Measure your dog's length from collar to base of tail before buying any bag; height isn't the only metric that matters.
- Test the "Carry Weight" by walking around your block for 15 minutes with the dog in the bag before attempting a subway trip.
- Keep a copy of the MTA Rules (Section 1050.9) bookmarked on your phone just in case you need to clarify the "enclosed" wording to a confused station agent.
- Invest in a cooling pad for the bottom of the bag during summer months to prevent heat exhaustion.
The new york subway dog bag culture is a testament to how much New Yorkers love their pets. We are willing to strap 50 pounds of fur to our backs and descend into a hot, loud tunnel just to have our best friends with us. It's awkward, it’s sweaty, and it’s a little bit crazy. But honestly? It’s the most NYC thing ever.
