Relocating to Spain with three dogs meant figuring out European train travel with pets from scratch. Rules vary significantly by country and operator — what's free in Italy costs €25 in France, and a dog perfectly welcome in Germany may be barred from a specific Spanish AVE route. This resource consolidates the policies for every major European rail operator in one place, so you're not piecing it together from six different websites the night before you travel.
Policies change frequently. Always verify directly with the operator before travel. We update this page as we learn of changes, but we cannot guarantee real-time accuracy.

From Experience
Tips from Traveling with Three Dogs
- Always carry your pet's EU passport and vaccination card — some operators will check, and missing documentation can mean removal at the next stop.
- For Renfe AVE large dog routes, arrive at the station 40 minutes early to complete the declaration of responsibility and collect the travel kit (seat cover and mat).
- Book pet tickets as early as possible — on Renfe Pet Friendly AVE trains, there is a maximum of two large dogs per train.
- Do not feed your dogs immediately before boarding. Motion sickness is a real risk, and most operators require you to deal with any mess — or leave the train.
- Bring a familiar blanket or silent toy to keep your pet calm during the journey.
- Policies change frequently and without notice. Always verify on the official operator website before travel, not a third-party booking site.
