Traveling with Pets

The short version

Bringing a dog or cat from the US to Spain is very doable. There is no quarantine and no blood test, and Spain is a country of dog lovers: you will see dogs on café terraces in Madrid, trotting through the old quarters of Seville at 11 p.m. and riding Renfe's high-speed trains, which opened up to big dogs in July 2026.

The hard part is the paperwork, and above all the timing. Your pet needs a microchip, then a rabies vaccine, then at least 21 days of waiting, then an EU health certificate from a USDA-accredited vet, then a USDA endorsement, all lined up so you land in Spain within 10 days of that endorsement. The EU introduced new certificate versions on October 1, 2026, so any guide or vet checklist written before that may show an outdated form.

The rest of this page walks you through the EU rules, a countdown timeline, airlines, Spanish pet law, getting around with a dog, the health hazards that surprise American owners, and the CDC rules for bringing your dog home.

EU entry rules for dogs, cats and ferrets

Spain applies the EU's common rules for pets traveling with their owners, which treat dogs, cats and ferrets the same way. The US is on the EU's list of approved countries, which is why your pet needs no rabies blood test.

• Microchip first. An ISO 11784/11785 microchip (the 15-digit kind) implanted before or on the same day as the rabies vaccine, and scanned by the vet before vaccinating. If your pet has an older non-ISO chip, either add an ISO chip and list both numbers, or carry a scanner that reads it.
• Rabies vaccination. Given at least 12 weeks of age, after the chip. A first (primary) vaccination needs at least 21 days before entry, or longer if the manufacturer says so. Boosters given before the previous shot expires carry no waiting period. A lapse of even one day sends you back to primary.
• EU health certificate. The non-commercial certificate for pet dogs, cats and ferrets, completed and signed by a USDA-accredited veterinarian. It is valid for entry within the window described below.
• USDA endorsement. APHIS must endorse the certificate within 10 days before your pet arrives in the EU. Your vet submits it through APHIS's online system (VEHCS), and APHIS signs and embosses the paper.
• The owner travels too. The non-commercial certificate applies when you (or a person you designate in writing) travel within five days of the pet. Otherwise, or with six or more pets, the stricter commercial rules apply.

The new 2026 certificates

The EU replaced its pet health certificates in 2026. The new non-commercial certificate took effect on October 1, 2026, and the new commercial one on October 17, 2026. If your vet starts a certificate from a template saved last summer, ask them to check APHIS's Spain page for the current form before you pay anything.

How long it lasts once you are in

The non-commercial certificate lets you travel on within the EU (by train to France, say, or by ferry to Italy) for up to six months from the date it was issued, as long as the rabies vaccination stays valid. If you stay longer or travel often, a Spanish vet can issue an EU pet passport once you are a resident; see staying longer with a pet below.

What Spain does not require

• No rabies titer (blood test) for pets coming from the US.
• No tapeworm treatment for dogs entering Spain. It is required if you then go on to Ireland, Malta, Finland or Norway, and the UK has its own rules.
• No quarantine, provided the documents and chip check out.

A countdown timeline

Work backward from the day you land in Spain. Here is a typical schedule for a dog or cat with no current rabies vaccine.

1. Three months or more before: Check the airline's pet rules and book your pet's spot, since cabin and hold places are limited per flight. Find a USDA-accredited vet and confirm they handle EU certificates.
2. Six to two months before: Microchip (if needed) and rabies vaccine on the same visit or with the chip first. Ideally give a fresh one-year vaccine two to six months before travel so it stays valid through your trip. Keep the vaccination certificate with the chip number, product name and batch.
3. At least 21 days before entry: The primary vaccine's waiting period must be over by the day you land.
4. About 10 days before: The vet examines your pet and completes the EU certificate, then submits it to APHIS online for endorsement.
5. Within 10 days of arrival: APHIS endorses. Pay for prepaid return shipping if you need the paper mailed back, or plan to collect it.
6. Travel day: Carry the original endorsed certificate (not a copy), the rabies certificate and your pet's records in your hand luggage.

Flying with a pet to Spain

Airline rules decide more about your trip than the EU rules do, and they change often. Call the airline before buying tickets, and get your pet's booking confirmed in writing.

In the cabin

Small dogs and cats usually travel in a soft carrier under the seat in front of you. European airlines commonly set a combined limit for pet and carrier around 8 kg (about 18 lb), and you cannot take the pet out during the flight. Fees are charged each way and vary by airline. Iberia and Air Europa fly nonstop from several US cities to Madrid, and US carriers fly to Madrid and Barcelona; see flights to Spain for routes. Some US airlines do not allow pets in the cabin on transatlantic flights, so check before assuming.

In the hold or as cargo

Bigger dogs fly in a crate in the hold, either as checked baggage on the airlines that still offer it, or as cargo through a professional pet shipper. Several US airlines no longer take pets as checked baggage, which pushes many owners of large dogs to European airlines or to shippers. Summer heat embargoes are common, and many airlines refuse snub-nosed breeds such as bulldogs, pugs, boxers and Persian cats in the hold, because they are prone to breathing problems.

Arriving in Spain

When you land at Madrid-Barajas, Barcelona-El Prat, Málaga or another international airport, the documents and microchip are checked as part of the entry process before you leave the arrivals area. Head for the red channel or ask customs staff where pet checks take place if no one approaches you. Have the original papers ready, and expect the officer to scan the chip.

Spanish pet law once you arrive

Spain passed a national animal welfare law in 2023 (Ley 7/2023), and regions and towns add their own rules. Most of it is common sense, but a few details catch visitors.

• Do not leave a dog alone too long. The law bans leaving dogs unsupervised for more than 24 consecutive hours, and leaving any animal in a parked car in the heat can bring a fine and a police call.
• Insurance: the 2023 law requires third-party liability insurance for all dog owners, but as of October 2026 the regulation that sets the minimum coverage had still not been published, so it is not yet enforceable nationwide. Some regions and towns already require it. Many US pet policies do not cover Spain, so a cheap Spanish policy or a travel liability policy is sensible.
• Leashes and cleanup: dogs are generally leashed in towns, and fines for not picking up are real. Many Spanish towns also require owners to rinse urine off sidewalks and building corners, which is why locals carry a small squeeze bottle of water on walks.
• Training course: the 2023 law also created a free owner training course, but it too awaits its regulation.

Potentially dangerous breeds

Spain has long had a special regime for perros potencialmente peligrosos (potentially dangerous dogs, often abbreviated PPP). The national list covers the Pit Bull Terrier, Staffordshire Bull Terrier, American Staffordshire Terrier, Rottweiler, Dogo Argentino, Fila Brasileiro, Tosa Inu and Akita Inu, their crosses, and dogs with most of the physical traits in the law's annex. Owners need a municipal license and liability insurance of at least €120,000 (about $134,000); Catalonia sets its minimum at about €150,000 (about $168,000). In public these dogs must wear a bozal (muzzle) and be on a short leash.

Trains, metros, buses and ferries

Trains are the best way to see Spain, and they are getting friendlier to dogs. See getting around for the train network in general.

Renfe

• Small pets in a carrier: dogs, cats and other small pets can ride with you in a closed transportín (pet carrier), roughly 60 x 35 x 35 cm (about 24 x 14 x 14 inches) and under about 10 kg (22 lb), for a small supplement (around €10, about $11, on standard fares in early 2026; some premium fares include it).
• Large dogs up to 40 kg: since July 21, 2026, Renfe accepts dogs up to 40 kg (88 lb) on its long-distance and many regional services, including AVE, Avlo, Alvia, Euromed, Intercity, Avant and Media Distancia. The surcharge is €40 (about $45) on the long-distance trains. There are two big-dog places per train in a designated car, the dog sits by the window next to you, and you need a non-extendable leash of 1.5 m (about 5 ft), a muzzle in stations and while boarding, the vaccination record or EU certificate, and a cleanup kit. Dogs under one year, dogs on the PPP list and females in heat are excluded.
• Cercanías (commuter rail) generally takes leashed, muzzled dogs; check the local network's rules.

Iryo and Ouigo

The private high-speed operators have their own rules. Iryo accepts small pets in carriers for a supplement and has run promotions for larger dogs; Ouigo has accepted only small dogs in carriers. Check each company's current policy before booking a route where they compete with Renfe.

City transit and taxis

Madrid's Metro allows dogs with a leash, a muzzle and a registered chip, in the last car, but not on weekdays from 7:30 to 9:30 a.m., 2 to 4 p.m. and 6 to 8 p.m. Small pets in carriers are accepted on most buses and metros elsewhere, while rules for larger dogs vary city by city, so check the operator's site. Taxi drivers can refuse a dog that is not a guide or assistance dog; ride-hailing apps sometimes let you flag a pet.

Buses and ferries

Long-distance coach companies generally take only small pets in carriers, if at all. Ferries to the Balearic Islands and the Canaries often have onboard kennels and sometimes pet-friendly cabins, which sell out in summer. Moving between mainland Spain and the islands needs no extra paperwork for a pet already legally in Spain.

Hotels, restaurants, beaches and trails

Where to stay

More hotels accept dogs every year, often with a cleaning fee and a weight limit, and apartment rentals let you filter for pets. A pet-friendly label does not always mean a big dog, so confirm the size limit directly. Rural houses (casas rurales) in the green north, Catalonia and Andalusia are often the easiest choice with a large dog. Our where to stay page covers booking in general.

Eating out

Café and restaurant terraces are the natural home of the Spanish dog, and you will rarely be turned away outside. Inside, it depends on the establishment and the regional rules. Look for a sticker reading pet friendly or se admiten perros (dogs allowed), and ask before you sit.

Beaches

Most Spanish beaches ban dogs, at least during the summer season (often June to September) and sometimes all year, with fines for owners who ignore the signs. Many coastal towns, including Barcelona and Valencia, set aside a playa canina (dog beach). Search for the phrase plus the town name, and check the season and hours on the town hall's website. In winter, rules on some quieter beaches relax, but follow what the posted signs say.

Hiking

Spain's mountains and long-distance trails are great with a dog, though national parks generally require leashes and some zones ban dogs to protect wildlife and livestock. Shepherds' guard dogs in the Pyrenees, the Picos de Europa and the Sierra Nevada can be protective; keep your dog close and give flocks a wide berth. See the outdoors page for trails and the Camino page if you are thinking of walking it with a dog, which many people do with planning.

Health hazards for dogs in Spain

Spain's climate brings a few risks American owners rarely meet at home. Ask your US vet about them before you go, and see a Spanish vet if you are staying a while.

• Heat: summer afternoons in Seville, Córdoba and Madrid often exceed 100°F (38°C), and pavement gets much hotter. Walk early and late, as Spaniards do, carry water and avoid long midday outings.
• Processionary caterpillars: the procesionaria nests in pine trees and comes down in long lines, mostly from late winter into spring. Their hairs cause severe reactions in a dog's mouth and tongue, and a sniff can mean an emergency vet visit. Keep dogs away from lines of caterpillars under pines.
• Leishmaniasis: a parasitic disease spread by sand flies, common around the Mediterranean and in central and southern Spain, especially from spring to autumn. Spanish vets routinely recommend repellent collars or spot-ons and keeping dogs indoors at dusk; a vaccine exists for longer stays.
• Grass awns: dry summer espigas (grass seeds) work their way into ears, paws and noses. Check your dog after walks in fields.
• Ticks in rural and wooded areas; use protection that covers them.

Vet clinics (clínicas veterinarias) are everywhere, and big cities have 24-hour emergency hospitals (look for urgencias veterinarias 24 horas). Prices are generally lower than in the US. Pharmacies sell some pet medicines, but vets handle prescriptions.

Traveling with a cat

Cats follow exactly the same EU rules as dogs: chip, rabies vaccine, 21 days, certificate and USDA endorsement. Most travel in the cabin, which is easier on them. A calm cat with a familiar carrier, a pad and a harness for security screening (you will take the cat out while the carrier is X-rayed) does well on a nonstop flight.

In Spain, cats usually stay put in your rental. Confirm before booking that the apartment allows pets, bring or buy a litter box (pet shops and supermarkets sell litter), and keep windows screened or closed: Spanish apartments often have balconies with gaps a cat can slip through. For long stays, a resident cat must be chipped and registered like a dog.

Bringing your pet home: the CDC rules

Since August 1, 2024, the CDC has applied stricter rules to all dogs entering the US, including American dogs coming home. The good news is that Spain is not on the CDC's list of high-risk countries for dog rabies, so the simpler track applies.

Dogs that have only been in low-risk countries

• Age: at least 6 months old on arrival in the US.
• Microchip that a universal scanner can read.
• CDC Dog Import Form: free, online, one per dog. You get a receipt to print or show on your phone, valid for six months as long as the dog does not visit a high-risk country. You can complete it on the day of travel, but do it a few days ahead.
• Healthy appearance on arrival. The dog can enter at any airport.

Your airline may ask for more, such as a recent vet health certificate. A Spanish vet can issue one; ask in advance. Some US states and territories, Hawaii above all, have their own stricter rules.

Cats coming home

The CDC does not require a form for cats, but airlines and some states may ask for a rabies certificate or a health certificate. Keep the EU paperwork and rabies records with you.

Staying longer with a pet

If you move to Spain, your pet becomes a Spanish resident too. Register the microchip in your region's pet identification registry through a local vet; it is mandatory for dogs, and in many regions for cats. The vet can then issue an EU pet passport, which replaces the US certificate for travel around the EU and back from the US.

Finding a rental that accepts a large dog can take longer than the visa. Mention the pet up front, offer a pet deposit within the legal limits, and bring vet records. Our long stays page covers visas, renting and the residence paperwork.
