The Metropolitan Transportation Authority (MTA) probably didn't realize they were creating a world-class comedy stage when they drafted Section 1050.9 of the New York City Transit Rules of Conduct. It’s a dry piece of bureaucracy. It basically says that 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 word "container" is the pivot point for everything.
It doesn't specify size. It doesn't define "bag." So, naturally, New Yorkers—being the most stubborn and creative rule-skirters on the planet—took that ambiguity and ran with it. Now, if you spend enough time on the L train or the 6, you’ll eventually see a seventy-pound Alaskan Malamute sitting calmly in a reinforced IKEA blue bag with leg holes cut out. It's hilarious. It's practical. It's New York.
The Law vs. The Large Dog
The rule was originally intended to keep pigeons and stray cats off the trains, or at least to ensure that the lap dogs of the Upper East Side stayed in their mesh carriers. But the city is expensive. Dog walkers are pricey. Sometimes you just need to get your Pitbull mix from Bushwick to a vet in Chelsea without paying for a fifty-dollar Uber Pet.
So, the "New York subway dogs in bags" phenomenon isn't just a meme; it’s a direct response to the friction of urban living. The MTA's wording is famously vague: "enclosed in a container." It doesn't say the bag has to be zipped shut. It doesn't say the dog’s head can't poke out. It just says the dog has to be in it.
I’ve seen a Great Dane in a literal camping duffel bag. The owner had to use a luggage cart to wheel the dog onto the platform. Technically? Within the rules. The conductors usually don't care as long as the dog isn't barking or biting. Honestly, most New Yorkers prefer a dog in a bag to a person playing music through a Bluetooth speaker without headphones.
Why This Became a Cultural Moment
Social media turned this into a sport. Accounts like @dogsinbags on Instagram started documenting the absurdity. You see Golden Retrievers in oversized backpacks looking like they’re heading to a corporate job. You see tiny Chihuahuas peering out of designer totes.
There’s a specific kind of pride in it.

If you can fit your dog in a bag, you're a "real" New Yorker. You've hacked the system. But it’s not all just for the 'gram. There are real logistics here. If a dog isn't in a bag, the fine can be up to $100. That’s a lot of kibble money.
The Evolution of the "Subway Bag"
In the early days, people just used what they had. The IKEA bag became the gold standard because it’s nearly indestructible and costs about a dollar. You’d see people at the Atlantic Ave-Barclays Center station quickly stuffing their Husky’s paws into the crinkly blue plastic as the train approached.
Then, the market caught up.
Companies like K9 Sport Sack started making heavy-duty backpacks specifically designed for large breeds. These aren't your grandma's pet carriers. They have cooling vents, lumbar support for the human, and safety straps. They can hold dogs up to 80 pounds. It’s a workout. Imagine carrying a bag of concrete that wiggles and occasionally tries to lick a stranger's ear. That’s the reality of the commute.
The Unspoken Social Contract
Most people think the subway is a lawless place. It kinda is. But when it comes to New York subway dogs in bags, there’s a weirdly strict etiquette.
- The Floor Rule: If your dog is big, you stay by the doors or in the corner. You don't take up a seat with a bag full of Golden Retriever.
- The "No Interaction" Rule: Even if the dog is the cutest thing you’ve ever seen, you don't touch without asking. Subway dogs are often stressed.
- The Muzzle Debate: Some larger dogs are muzzled even inside the bag. It’s an extra layer of "don't fine me" for the owners.
Interestingly, the MTA has never really cracked down on the "giant dog in a tiny bag" loophole. Why? Because it works. If the dog is in a bag, it isn't running around the tracks. It isn't tripping people in the aisles. It's contained. As long as the "annoy other passengers" clause isn't triggered, the NYPD officers on the platform usually just smile and take a photo.
Is it Actually Safe?
Safety is the part people ignore for the sake of the photo op. Putting a 60-pound dog in a bag and slinging it over your shoulder is a recipe for a herniated disc. Not for the dog—for you.

Veterinarians often point out that certain breeds shouldn't be held in "upright" positions for long. Dogs' spines aren't designed to sit vertically like a human’s. If you’re doing the 45-minute commute from the Bronx to Lower Manhattan, that’s a lot of pressure on their hips.
Then there’s the heat.
The NYC subway platforms in July are basically ovens. Sticking a furry animal into a nylon bag during a heatwave is risky. Responsible owners use cooling mats or battery-operated fans clipped to the bag. You have to be smart about it. A dog can overheat in minutes in an unventilated carrier.
The Economic Reality of the Bag Rule
Let’s be real: the rule is a bit classist.
If you have a small dog, you can buy a $20 carrier and go anywhere. If you have a large dog, you’re often forced to use expensive ride-share services or own a car, which is a nightmare in the city. By finding ways to get New York subway dogs in bags, owners are reclaiming their right to move around the city with their companions.
It’s about accessibility.
New York is increasingly a "dog city," but the infrastructure hasn't kept up. There are more dog runs than ever, but getting to them is the hurdle. The bag rule is a compromise. It’s the city saying, "We know you have a dog, just don't make it our problem."

Notable "Bag" Failures and Successes
I remember seeing a guy trying to get a Pitbull into a TJ Maxx bag. The bottom blew out before they even reached the turnstile. That’s a failure.
On the flip side, there’s a famous video of a guy with a huge dog in a literal burlap sack with holes for the legs. He carried it like a backpack. The dog looked like it was having the time of its life.
How to Do It Right
If you’re moving to the city and you have a dog that weighs more than a loaf of bread, you need a plan. Don't wait until you're at the subway entrance to try the bag for the first time.
- Desensitize early. Put the dog in the bag at home. Give them high-value treats (think chicken or cheese). Make the bag a happy place, not a "we're going to the loud metal tunnel" place.
- Check the stitching. If you’re using a DIY bag, double-stitch the handles. The last thing you want is a handle snapping while you’re walking over the gap between the train and the platform.
- Watch the temperature. If you’re sweating, your dog is dying. Open the bag as soon as you get off the train.
- Mind the tail. This is the most common injury. Tails get caught in zippers or stepped on when the bag is on the floor.
The Future of Furry Commuters
There have been occasional pushes to change the rules. Some animal rights groups want "leashed and muzzled" to be enough, similar to how it works in London or many European cities. In London, dogs just walk on the Tube. No bag required.
But NYC is denser. The trains are tighter.
The "dogs in bags" era is likely here to stay because it serves as a self-regulating filter. If you’re willing to carry your 50-pound dog in a bag, you’re probably a dedicated enough owner to ensure they behave. It’s a barrier to entry that keeps the subway from becoming a chaotic dog park.
It's a weird, beautiful, gritty part of New York life. It captures the city’s essence: strict rules, blatant circumvention, and a shared understanding that we’re all just trying to get where we’re going with our best friends in tow.
Actionable Steps for Commuting with Your Dog
- Measure your dog's "sitting height" and "length" before buying a carrier; most people buy bags that are too small, causing the dog to hunch painfully.
- Invest in a "Pet Passenger" style backpack with a rigid bottom if your dog is over 30 pounds; soft-sided bags will sag and put pressure on the dog’s joints.
- Keep a "Subway Kit" in the bag: a collapsible water bowl, a small towel (for accidents), and a spare leash.
- Avoid rush hour. If you have a massive dog in a bag, trying to board a packed 4-train at 5:30 PM is asking for trouble with both passengers and MTA staff.
- Check the "Service Animal" vs. "Pet" distinction. Remember that service animals are exempt from the bag rule, but misrepresenting a pet as a service animal is illegal and harms those who actually rely on them.
The New York subway dogs in bags phenomenon isn't going anywhere. It's a testament to the lengths people will go to for their pets. Next time you see a pair of fluffy ears sticking out of a rucksack on the Q train, just give the owner a nod. They’re likely carrying forty pounds of fur and probably have a very sore back.
