France · Regional bus rules
Can my dog travel on RATP-operated buses in Île-de-France?
Checked · Official source ↗
No. Your dog has to fit in a closed carrier.
What this means for you: The bus isn’t how a big dog moves around Paris; the metro and RER are. Underground it rides muzzled and on a lead, free. Above ground — bus and tram — it’s carrier only. Plan the region by rail: metro, RER, Transilien. Other Île-de-France Mobilités bus operators haven’t published a rule I could read; assume the same.
The rule, line by line
What RATP-operated buses actually say.
- Who gets on
- Small pets in a closed bag, basket or crate that fits them. Free.
- Who doesn’t
- A dog on a lead, whatever its size — on the buses and trams.
- How much
- Free for a small animal in a carrier.
- Where they ride
- In the carrier, with you.
- Never, whatever the size
- Category 1 and 2 dogs are refused across the network.
- Where this applies
- RATP-operated bus services only; not every Île-de-France Mobilités contractor — regional coaches. City buses are below. Double-check who actually runs your service.
- Assistance dogs
- Assistance and guide dogs ride free, without a muzzle — on a lead and in their identifying harness. RATP may ask for evidence.
City buses are a different story (sometimes)
Dogs on city buses in Paris
Regional coaches are one rule; the buses inside each town are another, set by the town’s own operator, and I read each one in the French. 1 of the 2 networks I could verify take a big dog on a lead and muzzle.
Where a big dog rides the city bus — on a lead and muzzled
There is one network where the idea is the same: lead, off the seats, and you clean up. Muzzles and fares vary, so read the row.
Bigger dogs ride the metro and RER free, muzzled and on a lead. Small animals in a closed bag, basket or crate ride free everywhere. Category 1 and 2 dogs are refused.
The RATP page blocks automated reading; this is its own indexed wording. Confirm on the page before you rely on it.
Where it’s carrier only
One network. A dog that fits in a closed bag or basket on your lap rides. A dog on a lead doesn’t, however calm.
On the buses and trams only small animals in a closed bag and assistance dogs are admitted. A big dog on a lead isn’t.

Your next step
So what do you do instead?
Three alternatives, in the order I’d try them.
- Choose a location that’s serviced by a train.Ideally a station in the town itself, not a railhead half an hour out. Look at the walk from platform to front door before you book — a dot on the map isn’t the same as an easy last connection with a big dog.
- Walk it.Under about 3 km on a proper path, walking usually beats the alternatives — and it’s the one option nobody can refuse you.
- Book a taxi, an Uber, or a private car service.Check they take dogs, and book before you go. Turning up at a rank with a 30 kg dog and no arrangement is where these trips actually fall apart.
