Italy's national railway is one of the easiest in Europe for dogs. On Trenitalia, dogs, cats and other small pets ride free in a carrier up to 70 x 30 x 50 cm. A dog of any size can also ride outside a carrier, on a lead and wearing a muzzle, with a dog ticket that Trenitalia prices at EUR 5 for journeys from Sunday to Friday and EUR 1 on Saturdays. You must carry the dog's papers, and dogs are not allowed in the Premium service level, the Quiet Zone or the restaurant car.
This guide is built from Trenitalia's travelling with your pet page and its travel with your dog page, read in November 2026. It covers Trenitalia's own trains, the Frecce high-speed services, Intercity and regional trains. Italo, the private high-speed operator, sets its own pet rules.

Small pets in a carrier ride free
Trenitalia lets dogs, cats and other small pets travel free in first and second class on all train types, and in the Executive, Business, Premium and Standard service levels, as long as they are in a pet carrier no bigger than 70 x 30 x 50 cm. Only one pet carrier is allowed per traveller. That carrier limit is far more generous than most European railways allow, so a small or medium dog that would need a ticket elsewhere can often ride free in Italy. Measure your dog lying down and standing before choosing a carrier: the 30 cm width is the tight dimension, and a dog that cannot turn around inside will not settle on a long trip. Soft carriers with a rigid base usually fit the limit best and still slide under a seat or onto your lap.
Dogs of any size on a lead
Each passenger can bring one dog of any size outside a carrier, as long as it is kept on a lead, wears a muzzle, and has a ticket for the route. Trenitalia's pet page prices the dog ticket at EUR 5 for journeys from Sunday to Friday and EUR 1 for journeys on Saturday. That price is low even on a long Frecciarossa trip, which makes the train one of the cheapest ways to move a large dog around Italy.
Trenitalia's FAQ and regional pages describe dog fares on some services differently, as a discount on a second-class ticket. The booking system shows the price for your train when you add the dog, so treat that figure as final.
Which trains and classes allow dogs on a lead
Trenitalia lists where a dog on a lead can travel:
Frecciarossa, Frecciargento and Frecciabianca. First and second class, and the Executive, Business and Standard service levels. Dogs on a lead are not allowed in the Premium level, the Meeting Area, the Quiet Zone (Area Silenzio) or private compartments.
Intercity and Intercity Night. First and second class. In sleeping cars, couchettes and Excelsior cabins, a dog can travel only if you buy the entire compartment.
Regional trains. Allowed on all regional trains, except those explicitly marked otherwise in the official timetable.
The Premium exclusion is the one that surprises people, since a small pet in a carrier is allowed in Premium. If you are travelling with a large dog, book Standard, Business or Executive instead.
How to buy a dog ticket
On the Trenitalia website or app, choose your train, pick your fare offer, and before you pay, add the "Travelling with your dog" service. The dog's ticket price appears and goes into your cart with your own ticket. You can also get the dog ticket at station ticket offices, self-service machines, authorised travel agents, or through the Trenitalia call centre.
Papers your dog needs on board
Trenitalia says two documents are mandatory for travel: your dog's canine registry certificate and its health booklet. For foreign owners, the dog's pet passport replaces both. Have the document in your hand luggage, not in a suitcase, because onboard staff can ask to see it. A US dog that has just arrived in Italy will usually have an endorsed EU health certificate rather than a passport; carry it with the rabies certificate and microchip record.
No dogs in the restaurant car
Dogs cannot go into the restaurant or cafe carriage. On a long Frecciarossa trip, that means one person stays with the dog while the other fetches food, or you bring your own food on board.
Guide dogs
Guide dogs for blind and visually impaired passengers travel on all trains free of charge and do not need a pet ticket.
Cats and other small animals
Cats and other small pets must travel in a carrier; the lead and muzzle option is only for dogs. With a carrier up to 70 x 30 x 50 cm, most cats travel free and in comfort. Line the carrier with an absorbent pad on long trips, and keep the carrier closed for the whole journey, even if the cat seems calm.
International trains to and from Italy
Cross-border trains follow the rules of the operators involved. Deutsche Bahn allows small dogs in a container up to 70 x 30 x 50 cm free on trips to Italy, as our Deutsche Bahn guide explains. From France, SNCF sells TGV trips to Italy with a "domestic animal in a carrier" fare and a "dog on a lead" fare. Check the conditions on the operator selling your ticket before you book, since cross-border fares do not always match domestic Trenitalia prices.
Documents for bringing a dog into Italy
Italy follows the EU pet movement rules: a microchip, a valid rabies vaccination, and an EU pet passport or, for dogs from outside the EU, an animal health certificate. The European Commission explains the rules on its movement of pets page, and the USDA covers the US side on its US to Italy page. Our guide to moving a pet to Italy puts the steps in order.
Flying in and continuing by train
Rome Fiumicino has a direct rail link into the city, so a dog that arrives on an international flight can continue by train once it has cleared the airport. If your dog flies in the cabin, it can be on a train within a couple of hours of landing. If it flies as checked baggage or cargo, allow time for collection and a long walk first. Our ITA Airways guide covers the flight rules on the most direct route from the US.
Muzzle training before the trip
Trenitalia requires a muzzle for every dog outside a carrier. If your dog has never worn one, train it for a few weeks before travelling: let it sniff the muzzle, reward it for putting its nose in, then build up the time it wears it. A basket muzzle lets the dog pant and drink, which matters on a hot day in a crowded coach.
Summer travel with a dog in Italy
Italian summers are hot, and platforms can be hotter than the trains. Travel early or late in the day, carry water, and avoid long waits on open platforms in the afternoon. A dog that is panting heavily before boarding will not settle well on the train.
Overnight on Intercity Night with a dog
Intercity Night trains run long routes between the north and south of Italy, and they can be a practical way to move a dog down the length of the country without a long drive. A dog on a lead can travel in seated first or second class. If you want a sleeper, couchette or Excelsior cabin, Trenitalia only allows the dog if you buy the entire compartment. That costs more, but for a long night with a large dog it is the comfortable option, since the dog has floor space and you are not sharing with strangers.
What a typical trip costs
Take a Milan to Rome Frecciarossa journey on a Wednesday with a Labrador. You pay your own fare, and the dog ticket on Trenitalia's pet page is EUR 5. A cat or small dog in a carrier on the same train rides free. Do the same trip on a Saturday and the dog ticket is EUR 1. Even with a whole compartment on a night train, the dog itself costs very little; the bigger spend is the compartment and your own fare. Compare that with a pet transporter or a long drive and the train usually wins for a single dog within Italy.
Assistance dogs that are not guide dogs
Trenitalia's pet pages name guide dogs for blind and visually impaired passengers as travelling free without a pet ticket. They do not describe other assistance dogs in the same place. If you travel with a trained assistance dog for another disability, contact Trenitalia's assistance service before you travel to confirm how the dog will be treated, so you do not end up paying a pet fare or being asked for a muzzle at the platform.
Large dogs on busy trains
Trenitalia allows a dog of any size, but space at your feet is limited, especially in Standard on a full Frecciarossa. A large dog is easier to settle in a seat at the end of a coach or in a row with more legroom, and on a less crowded train. Avoid the Friday evening and Sunday evening peaks between Milan, Florence, Rome and Naples if you can, and keep the dog close so the aisle stays clear for the trolley and other passengers.
Italo and other operators
Italo, the private high-speed railway that competes with Trenitalia on the main north to south line, is a separate company with its own pet rules and prices. Regional lines run by other companies, and city metros and buses, also set their own terms. Do not assume a Trenitalia dog ticket covers any of them; check with the operator that runs your train.
Moving to Italy with a dog
If the train ride is the end of a move, the paperwork is the hard part. A dog coming from the US needs a microchip, a rabies vaccination given after the chip, a waiting period, and a USDA-endorsed health certificate issued shortly before the flight. Our pet passport guide explains why that certificate, not an EU passport, is what a US dog carries, and our moving abroad with a dog guide puts every step on a timeline.
Practical tips
Book Standard or Business rather than Premium if your dog rides on a lead. Avoid the Quiet Zone. Walk the dog before boarding, since stops are short. Keep the dog's papers and ticket together. On a Saturday, the EUR 1 dog ticket makes weekend trips especially cheap, so a Saturday departure can be worth it if your dates are flexible.
How Italy compares with the rest of Europe
Trenitalia's rules are among the most dog-friendly on the continent. The free carrier limit of 70 x 30 x 50 cm is larger than in France, and the dog ticket is a small flat amount rather than a share of your own fare as in Germany. The trade-offs are the paperwork rule and the muzzle, which applies to every dog outside a carrier. If you are touring Europe by rail, Italy is likely to be the easiest leg, while trains into Britain are closed to pets entirely, as our Eurostar guide explains.
