Are Dogs Allowed on the Subway? A City-by-City Guide

Traveling with your pup can feel like a scavenger hunt—each city has its own underground rulebook. One stop you’re applauded for bringing your French Bulldog, the next you’re politely shown the exit because the carrier zipper is 2 cm too short.
If you’ve ever typed “are dogs allowed on the subway?” at 7 a.m. while your train whistles away, this guide is for you. Below, you’ll find the essential dog-friendly subway rules for major global cities, plus insider tips to keep tails wagging and fellow passengers smiling.

New York City (MTA)

Are dogs allowed? Yes—if they’re “contained in a bag or carrier” that won’t annoy other riders.
Key rules
- Must fit on your lap (interpretation varies; yes, people use IKEA bags).
- No extra fare.
- Service animals may ride without a carrier.
Local quirk: New Yorkers love the “big dog in a tiny bag” loophole—viral pics prove it still works.
Tip: Avoid rush hour (7–9 a.m., 4–7 p.m.) when platforms are sardine-packed.

London (London Underground & Overground)

Are dogs allowed on the Tube? Absolutely, and leashes—not carriers—are the norm.
Key rules
- Dog must be on a short lead or carried.
- Stairs & escalators: carry small dogs; ask staff to stop the escalator if you have a big dog uncomfortable with moving stairs.
- No ticket needed.
Local quirk: Many stations keep a stash of dog treats behind the help point—ask nicely!
Tip: The front or rear carriage is usually quieter for anxious pups.

Paris (Métro & RER)

Are dogs allowed? Yes, with size caveats.
Key rules
- Small dogs (≤ 30 cm at shoulder) ride free in carriers.
- Larger dogs need a child ticket and must wear a muzzle plus leash.
- Dogs banned 7–9 a.m. & 4:30–6:30 p.m. on weekdays if bigger than carrier size.
Local quirk: Parisian conductors rarely measure, but they do check the muzzle.
Tip: Buy a “carnet” of child tickets to save time if you have a medium-size companion.

Berlin (U-Bahn & S-Bahn)

Are dogs allowed? Yup—Berlin is famously pup-friendly.
Key rules
- Small dogs in carriers ride free.
- Large dogs need a reduced-fare ticket (Hund Fahrschein) and a leash; muzzle required only on busy lines.
- Limit: one non-caged dog per passenger.
Local quirk: Some carriages have flip-up seats; locals sit on the floor with their dogs during quiet hours.
Tip: Purchase the dog ticket with your own “Kurzstrecke” at the same machine—no need for a second transaction.

Tokyo (Tokyo Metro & Toei)

Are dogs allowed? Yes, if fully enclosed. Think airline-approved carrier under 70 cm total length.
Key rules
- Carrier must stay closed; no heads popping out.
- No barking—staff can ask you to disembark.
- Pets ride free if carrier within size limit.
Local quirk: Commuters appreciate silence; noise-blocking blankets earn smiles.
Tip: Use station elevators (“E”)—escalators are crowded and steep.

Rome (Metro)

Are dogs allowed? Yes, with Latin flair and some paperwork.
Key rules
- One dog per passenger.
- Medium & large dogs need muzzle + leash + €1.50 ticket (valid 100 min).
- Small dogs in carriers ride free.
Local quirk: Sunday mornings are almost empty—perfect for training nervous pups.
Tip: Always carry your dog’s vaccination booklet; inspectors occasionally ask.

Toronto (TTC)

Are dogs allowed? Yes—but only outside peak hours.
Key rules
- Allowed before 6:30 a.m., 10 a.m.–3:30 p.m., after 7 p.m., and all day weekends/holidays.
- Must be leashed or in a carrier.
- No fare for pets.
Local quirk: Streetcar operators sometimes hand out “good boy/girl” stickers—collect them for fun!
Tip: Arrive ten minutes before peak-hour cutoff; station staff close gates right on time.

Sydney (Sydney Trains & Metro)

Are dogs allowed? Not on regular trains, but there’s a workaround.
Key rules
- Only assistance animals allowed on suburban services.
- Non-service dogs can ride “Pet Seating” on intercity regional trains (carrier only; book in advance).
Local quirk: Ferries are far more pet-friendly—many locals skip the rail altogether.
Tip: For city travel, use buses with “Pets in Carriers OK” decals or grab a pet-friendly rideshare.
