Short answer: in 2026 there is no single European rule for travelling by train with an animal — every operator sets its own fares and conditions. The key benchmarks: in France, SNCF charges around €7 for an animal under 6 kg carried in a bag and a reduced-fare ticket (about €20 on TGV Inoui) for a larger dog, kept on a lead and muzzled. In Germany, Deutsche Bahn carries animals free of charge if they fit in a closed hand-luggage-sized carrier, and applies a child's ticket for large dogs. In Austria, ÖBB asks for 50% of the full fare for a muzzled dog. In Italy, Trenitalia and Italo accept small animals in carriers (often free or for a token fee) and large dogs for a supplement. On the Nightjet and European Sleeper night trains, an animal almost always means booking the entire compartment for private use. Finally, Eurostar refuses all animals apart from assistance dogs. As for paperwork: the EU pet passport, a microchip and a valid rabies vaccination are mandatory as soon as you cross a border.
The scene plays out every summer on the platforms of Gare de Lyon, München Hauptbahnhof or Milano Centrale: a traveller turns up with their dog, discovers at the ticket check that they're missing a muzzle, a ticket or an entry in the passport — and ends up negotiating on the platform while the train whistles. None of this is fatal: the rules are public, stable, and fit on a single page once you line them up side by side.
Here is the complete playbook: the essential paperwork, the fares operator by operator, the special case of night trains, and the small habits that make the difference between a calm journey and eight hours of stress.
The paperwork: what EU rules actually require
This is the only genuinely harmonised part. Regulation (EU) 576/2013 governs the non-commercial movement of pet animals between member states. Three items can be demanded at any time, including on an international train:
- Microchip identification (transponder compliant with ISO 11784/11785). Tattoos are only accepted if they are legible and were done before 3 July 2011.
- The EU pet passport, issued by an authorised vet. It brings together the animal's identity, the chip number, vaccinations and the owner's contact details.
- A valid rabies vaccination. A key point that is often overlooked: the initial vaccination is only valid after a 21-day waiting period. A dog vaccinated the day before departure is not compliant.
On top of that come national requirements. The United Kingdom, Ireland, Malta, Finland and Norway require tapeworm treatment (a praziquantel-based wormer) administered by a vet between 24 and 120 hours before arrival, recorded in the passport. Sweden and Denmark have their own entry formalities, to be checked on official websites before you set off.
Worth remembering: the limit is five animals maximum per traveller for a non-commercial trip. Beyond that you move into a commercial regime, with a health certificate and stricter checks.
For reference sources, consult the European Commission portal (the "Travelling with pets" section), the website of the French Ministry of Agriculture and, for each destination, the embassy or national veterinary service. These are the only authoritative sources; forums, by contrast, regularly spread outdated rules.
SNCF: the French scale, simple but not free
SNCF distinguishes two categories, based on weight and carrier:
| Situation | Conditions | Indicative 2026 fare |
|---|---|---|
| Animal under 6 kg | In a closed bag or basket measuring 45 × 30 × 25 cm maximum | About €7 per journey |
| Dog over 6 kg | On a lead and muzzled, at your feet | Reduced-fare ticket, often around €20 on TGV Inoui |
| Guide or assistance dog | On presentation of the card | Free, no muzzle required |
On TER and Intercités, the same principles apply with regional variations: some regions charge a lower flat fee, others let small animals travel free. On Ouigo, the animal ticket also exists, but floor space is tighter — plan ahead if your dog is over 15 kg.
The practical detail that changes everything: the animal must never occupy a seat. A conductor can legitimately require the bag to go on the floor or on your lap. An approved carrier bag with a rigid base avoids that kind of discussion, and has the advantage of being accepted in the cabin by most airlines too — handy if your trip combines rail and air.
Germany, Austria, Switzerland: the three busiest regimes
Deutsche Bahn: the most generous in Europe
DB applies a crystal-clear rule: an animal travelling in a closed carrier the size of a piece of hand luggage is carried free of charge, with no limit on any reasonable number. A dog that doesn't fit that format travels on a lead and muzzled, with a ticket equivalent to a child's fare (half the adult price on most ICE and IC services). BahnCard discounts do not apply to the animal.
ÖBB: 50% of the fare, muzzle compulsory
In Austria the rule comes with a number attached: half the price of a 2nd-class ticket, whatever the size of the dog, unless it travels in a hand-luggage-sized carrier (free). A muzzle and a lead are required at the same time on ÖBB trains — this is the point Austrian conductors are strictest about. An adjustable basket muzzle, more comfortable than a fabric model on a journey of several hours, fits in a side pocket of your bag and saves you from being refused boarding in Salzburg or Innsbruck.
SBB/CFF: the day pass for dogs
Switzerland has invented the most readable system: a fixed-price day pass for dogs (around CHF 25), valid all day across the whole SBB network, PostBus services and most urban transport included. For a traveller stringing together Zurich → Lucerne → Interlaken in the same day, it's unbeatable. Small animals in a closed basket less than 30 cm high travel free. An annual dog pass is also available for residents.
Italy, Spain, Benelux: the rules not to mix up
Trenitalia accepts small animals (up to 10 kg) in a carrier measuring 70 × 30 × 50 cm maximum, free of charge in 2nd class on most regional trains, with a modest supplement on Frecciarossa. Large dogs travel muzzled and on a lead, with a reduced-fare ticket, and are barred from restaurant cars. Italo follows similar logic, with a flat supplement and the obligation to reserve the space at the time of purchase.
Renfe has relaxed its rules in recent years: animals up to 10 kg are allowed in a closed carrier on AVE and Larga Distancia services for a supplement of about 10% of the ticket price, and the operator has trialled admitting larger dogs on certain routes. On Cercanías and the regional network, carriage is generally free in a carrier.
In the Netherlands, NS offers a cheap day ticket for dogs (a few euros) valid across the whole network; animals in a bag travel free. In Belgium, SNCB applies a similar principle with a flat supplement for large dogs.
The Eurostar case deserves to be spelled out in black and white: no pets are allowed on board Eurostar trains, including on the Paris–Brussels–Amsterdam routes inherited from Thalys. Only assistance dogs registered in advance are accepted. To cross the Channel with an animal, the remaining options are LeShuttle (the Eurotunnel shuttle, with your vehicle) or the ferry.
Night trains: the private-compartment rule
This is where travellers get caught out most often. On ÖBB's Nightjet services, an animal is only allowed if you book the entire compartment — couchette or sleeping car. So it's impossible to travel with your dog in a shared reclining seat or in a six-berth couchette compartment where other passengers are expected. In practice, a Paris–Vienna trip with a dog costs the price of four to six berths, which radically changes the budget equation.
European Sleeper, which operates the Brussels–Berlin–Prague routes and the new services to Hamburg, applies a similar policy: animals allowed in a privately booked compartment, on request at the time of reservation. Sweden's Snälltåget is more flexible, with carriages specifically designated as pet-friendly — a Nordic model that deserves to be copied.
A few reflexes for a night on board:
- Book by phone or email rather than online: booking engines handle the animal option badly, and written confirmation protects you in case of a dispute.
- Take a collapsible silicone bowl and a bottle of water: night-train corridors have no suitable water point.
- Pack a fleece blanket for your dog: compartments are aggressively air-conditioned in summer, and the floor is hard.
Preparing the animal, not just the file
A dog that has never taken a train understands neither the noise of the pneumatic doors nor the vibrations at 300 km/h. Preparation counts as much as the paperwork.
Get them used to it gradually. Two or three short TER journeys before a Paris–Milan trip are worth more than one big leap. For cats the rule is even clearer: the journey almost always goes better if the carrier is left open at home in the preceding weeks, with a familiar blanket inside.
Manage mealtimes. An animal fed three to four hours before departure, rather than just beforehand, copes far better with the journey. Take a small quantity of dog treats to reward calm behaviour at stops, rather than a full meal on board.
Plan the breaks. Long stops (Munich, Zurich, Milan, Vienna) often last 10 to 15 minutes, but getting off onto the platform is risky: doors that close on time show no mercy. Better to identify in advance the stations where your connection exceeds 40 minutes and head outside there. Many major European stations now have signposted dog areas.
Chemical calm is not a default solution. Veterinary sedatives should only be used on prescription and after a trial at home. Gentler alternatives — a calming pheromone diffuser sprayed on the blanket 15 minutes before departure — give good results on medium-length journeys and carry no risk.
What it really costs: three typical itineraries
| Itinerary | Animal | Estimated cost for the animal |
|---|---|---|
| Paris → Brussels (TGV/Eurostar) | Cat in a bag | Eurostar: refused. Flixbus alternative: allowed depending on operator |
| Paris → Munich (TGV + ICE) | 20 kg dog, muzzled | ≈ €20 (SNCF leg) + DB child fare ≈ €30 |
| Zurich → Interlaken → Lucerne, same day | 25 kg dog | 1 SBB day pass ≈ CHF 25 |
| Vienna → Rome (Nightjet) | 10 kg dog | Whole compartment to book privately: × 4 to × 6 the price of a berth |
The lesson is clear: on daytime journeys, the animal remains a marginal expense, often under €30 per border. On night trains, by contrast, it becomes the heaviest single cost of the trip — to the point where a Paris–Vienna return in a privately booked couchette can exceed the price of four plane tickets. In that case, splitting the journey into two daytime legs with a night in a pet-friendly hotel often works out cheaper, and is less tiring for the animal.
The checklist to tick off before you leave
- Microchip readable and number recorded in the passport.
- Rabies vaccination given more than 21 days ago and still valid.
- EU pet passport in a waterproof pouch, with a photocopy in a separate bag.
- Tapeworm treatment if you're heading to the United Kingdom, Ireland, Malta, Finland or Norway.
- Animal ticket bought before boarding — sorting it out en route costs more and depends on the conductor.
- Muzzle in the bag, even if the country of departure doesn't require one: a connection in Austria or Italy will make it compulsory.
- Contact details for a vet at your destination, and confirmation that your pet health insurance covers you abroad.
- A short lead for corridors, a comfortable harness for the waiting hours.
One final and most useful piece of advice: write to the customer service department of every operator involved at least two weeks before departure and keep the reply. On a Paris–Prague trip with three successive operators, that's the only document that settles a disagreement on the platform. The train remains, by far, the mode of transport most respectful of animal welfare in Europe: no hold, no pressurisation, no separation. It simply asks for a little more preparation than buying a ticket and climbing aboard.
