Country guide · UK to Spain
Plan your pet trip to Spain.
Spain asks for the same paperwork as any EU trip, but there's no short hop across. The real decision is the route: a 33-hour ferry over the Bay of Biscay, a two-day drive through France, or a cargo flight, and each one treats your dog differently.
Worth knowing first
The tapeworm tablet for dogs is a UK return requirement only, given by a vet 24 to 120 hours before arriving back. Spain doesn't ask for it on the way in. Read the tapeworm rule→
Spain keeps a national list of eight "potentially dangerous" breeds, and the Staffordshire Bull Terrier is on it alongside the Rottweiler, the Akita and the pit bull types. Listed dogs go muzzled and on a short lead in public, and the owner needs a licence and third-party liability insurance. Check your breed→
Six weeks is the realistic minimum if the rabies vaccination is current. If rabies is overdue or has never been given, allow another month for the 21-day wait and the AHC window. How the AHC works→
Why this corridor matters
Spain is one of the most popular destinations for UK pet owners, and the hardest one to reach in a single hop. There's no tunnel and no 90-minute ferry; getting a dog there means a long Biscay crossing, a drive down through France, or a flight in the hold. Picking the route early matters more here than on any other EU corridor, because the pet-friendly options are the first to sell out.
For UK residents, the rules changed twice. First in 2021, when leaving the EU meant the Animal Health Certificate replaced the old pet passport for new trips. Then on 22 April 2026, even unexpired UK-issued EU pet passports stopped being accepted as travel documents. The AHC, issued within 10 days of each trip, is now the only route.
Trips on this corridor run longer than most: winter stays, second homes, a month on the coast rather than a long weekend. The advice on this page is written for trips of up to six months, which is what the single Animal Health Certificate covers. On top of the EU basics sits Spain's restricted breed list, which reaches breeds most UK owners think of as family dogs.
Routes in and out
Brittany Ferries sails from Portsmouth and Plymouth to Santander and Bilbao, with the longest crossings around 33 hours. Pets don't stay in the car on these routes; they travel in a pet-friendly cabin with you or in a reserved kennel, with exercise areas on deck and a muzzle required while walking through the ship. Cabins are limited per sailing and sell out months ahead for summer. Foot passengers can't bring pets.
Cross to Calais by Le Shuttle or ferry, then it's roughly 1,000 km to the Spanish border, a comfortable two days with an overnight stop. The paperwork is checked once, before the Channel crossing; France adds no further checks on the way through. One catch: French breed law applies while you're on French soil, and France bans some dogs outright that Spain only restricts, so check both countries before planning this route.
Flying out is easier than flying back. A few EU airlines, Iberia among them, take small dogs and cats in the cabin on departures from Britain when pet and carrier together stay under about eight kilograms; anything larger flies in the hold, booked as cargo through an agent. The return is the harder leg: UK entry rules require pets arriving by air to travel as cargo, whatever the airline. Many owners fly out and come home by ferry or road. In summer, heat embargoes can also suspend animal cargo at Spanish airports.
Common mistakes
- Booking a tapeworm treatment for entry into Spain when it's only required on the UK return.
- Leaving the pet cabin until last. The Biscay ferries carry a fixed number of pet spaces, and summer sailings fill months in advance.
- Microchipping a pet after the rabies vaccination, which means the vaccination doesn't count for travel and has to be redone after a new chip.
- Driving down with a listed breed and only checking Spain's rules. France sits in the middle of the route, and its categories are stricter than Spain's list.
Corridor FAQ
Yes. The Staffie is on Spain's potentially dangerous list, so it goes muzzled and on a lead of under two metres in public, and the owner needs a licence and third-party liability insurance of at least 120,000 euros. Entry itself is fine. If you're driving down, check the French rules for the transit too; France treats pit bull types without pedigree papers far more strictly.
Yes. Pets from Britain enter through an approved travellers' point of entry, where you declare the dog to the Guardia Civil. On the Santander and Bilbao ferries, and on the drive down through France, this step is easy to overlook, so check the point you're using before you set off.
In a pet-friendly cabin with you, or in a kennel you reserve when booking. Pets can't stay in the car on the Spanish routes because the crossing runs overnight, and the car decks are closed at sea. The cabin is the comfortable option and the first to sell out.
On the way out, possibly. Iberia and some other EU airlines take small pets in the cabin on flights leaving Britain, with a weight cap of about eight kilograms including the carrier. The return is different: UK rules require pets arriving by air to enter as cargo, so no airline offers a cabin option home. Plan the return leg before booking the outbound one.
Not for trips of six months or less. The certificate issued before you leave covers travel inside the EU and the return to Britain within that window. For longer stays, a Spanish vet issues a GB Pet Health Certificate for the return.
