Taking a Dog or Cat to Spain from the US — 2026 Requirements

Flying to Spain with a dog or cat takes about 4–6 weeks of prep and costs $375–550 one way for cabin travel. Spain follows standard EU import rules: ISO microchip, rabies vaccine with a 21-day wait, an EU health certificate from a USDA-accredited vet, and USDA endorsement ($101).

No quarantine, no blood test, no import permit.

Spain doesn't ban any dog breeds from entering the country, but it does classify 15 breeds as "potentially dangerous" (PPP) under Spanish law. That means muzzle and leash rules once you arrive, not a border rejection.

The timing pressure is the same as other EU countries: your health certificate has to be endorsed by USDA within 10 days of arriving in Spain.

This guide covers entry rules, airline options, the PPP breed system, costs, and return paperwork for both dogs and cats.

What You Need

Spain is an EU member state. Pets from the US enter under EU Regulation 576/2013 for non-commercial movement. The rules are the same for dogs and cats.

• ISO 15-digit microchip, implanted before rabies vaccine
• Rabies vaccine given after the microchip. Pet must be at least 12 weeks old. First-time shots need a 21-day wait before travel (some manufacturers recommend 30 days — check the label)
• EU health certificate signed by a USDA-accredited vet
• USDA endorsement within 10 days of arriving in Spain ($101)
• Owner or authorized person must travel with the pet (or within 5 days). If neither can travel within 5 days, you need the stricter "commercial" health certificate instead (48-hour endorsement window)
• Max 5 pets per person on the non-commercial certificate. Six or more requires the commercial certificate
• No quarantine
• No import permit
• No titer test (US is on the EU's approved-country list under EU Regulation 577/2013)
• Owner or designated person must sign the Declaration page on the back of the EU health certificate before travel. This page must accompany the pet and certificate to Spain
• Original endorsed health certificate must travel with the pet. Bring copies as backups, but customs officials check the original

Rabies Vaccine and Microchip

Your pet needs an ISO 11784/11785 microchip (15-digit) implanted before the rabies vaccine. If your pet got the rabies shot before the microchip, Spain won't accept it. You'd need a new vaccination and a new 21-day wait.

Critical

The first rabies vaccine given after microchip implantation counts as a "primary" vaccination under EU rules. It's valid for only 1 year, even if the label says 3 years. Boosters given within 12 months of the primary can be valid for 1–3 years per the manufacturer's instructions. If the booster lapses by even one day, the next shot resets to "primary" status.

The 21-day wait applies only to primary vaccinations — though some vaccine manufacturers recommend 30 days for full immunity. Check the label and ask your vet which wait period applies to your pet's specific vaccine. If your pet already has a current rabies vaccine that was given after microchipping, and the booster is up to date, there's no waiting period.

Most vets handle EU pet travel paperwork regularly and know this timing.

Puppies and kittens under 16 weeks: Pets younger than 16 weeks can't meet the rabies vaccination requirements (minimum age 12 weeks + 21-day wait). The EU has a separate pathway for young pets — check with your vet and the destination country's rules before booking travel with a young animal.

Microchip cost: $25–50. Rabies vaccine: $15–30. Your vet can do both in the same visit, but the chip goes in first. Spanish customs officials scan the microchip to match your pet to its health certificate.

EU Health Certificate

Spain has two versions of the EU health certificate: non-commercial and commercial. Most pet owners use the non-commercial version.

Non-commercial certificate — use this if you or a designated person (family member, friend, or authorized traveler) is traveling with the pet or within 5 days of the pet, and you have 5 or fewer pets. A USDA-accredited vet fills this out after examining your pet and confirming the microchip number, rabies vaccine dates, and overall health. Not every vet holds this accreditation — find one near you. Valid for 30 days from the date your vet signs it. USDA endorsement must happen within 10 days of your arrival in Spain.

Commercial certificate — required if neither you nor a designated person can travel within 5 days of the pet, or if you're traveling with 6 or more pets. Much tighter window: the vet must issue the certificate and USDA must endorse it within 48 hours of the pet leaving the US.

Most travelers use the non-commercial certificate. Schedule the vet visit about 7–10 days before your flight, then send the certificate to your regional USDA endorsement office immediately.

Most USDA offices process endorsements in 2–3 business days by mail. In-person endorsement is same-day at most offices. The certificate needs an original ink signature and USDA stamp/emboss. Airlines check this at the counter before your pet boards.

USDA Endorsement

USDA endorsement is the government stamp confirming your vet filled out the health certificate correctly. Spain won't accept an unendorsed certificate.

The endorsement costs $101 per certificate when no lab tests are needed (Spain doesn't need any for US travelers). If you're traveling with multiple pets on the same certificate, it's still $101 total.

Without this stamp, Spanish customs will reject your health certificate at the border.

Options:

• By mail: 2–3 business days. Ship overnight both ways if your timeline is tight
• In person: Same-day at your regional APHIS office. Call ahead to confirm hours and walk-in availability

The endorsed certificate is valid for 10 days for entry into the EU. Once you're in Spain, it covers travel within the EU for 4 months from the date of issuance, as long as your pet's rabies vaccination doesn't expire. If you're visiting multiple EU countries, you don't need separate certificates for each one.

Watch Out

If you take your dog from Spain to Finland, Malta, Ireland (including Northern Ireland), or Norway, your dog needs tapeworm treatment (echinococcus) from an EU veterinarian 1–5 days before entering those countries. This doesn't apply to cats or ferrets.

Spain's "Potentially Dangerous Dog" System and Ownership Rules

Spain doesn't ban any breed from entering the country. Every breed can cross the border.

But Spain classifies 15 breeds as "potentially dangerous" (Perros Potencialmente Peligrosos, or PPP) under Royal Decree 287/2002.

PPP breeds: Pit Bull Terrier, American Staffordshire Terrier, Staffordshire Bull Terrier, Rottweiler, Dogo Argentino, Fila Brasileiro, Tosa Inu, Akita Inu, Bullmastiff, Dobermann, Dogo de Burdeos, Neapolitan Mastiff, Presa Canario, Presa Mallorquín (Ca de Bou), and Tibetan Mastiff.

What PPP means in practice:

• Your dog must be muzzled and on a leash no longer than 2 meters in all public places.
• One person can walk one PPP dog at a time.
• Officials may require PPP dogs to wear muzzles during the post-entry veterinary check at the airport.

Ownership rules for ALL dogs: Under Spain's 2023 Animal Protection Law, two rules now apply to all dog owners in Spain, regardless of breed:

1. Mandatory Civil Liability Insurance: Every dog owner must have insurance covering potential damage to third parties.
2. Responsible Ownership Course: Residents and long-term visitors must complete a mandatory training course on responsible dog ownership (usually free and available online).

Watch Out

New EU-wide pet travel regulations are scheduled to take effect on April 22, 2026. These may introduce stricter requirements for digital certificate verification across all member states, including Spain.

Spain's 2023 Animal Protection Law signaled a move toward scrapping the breed list in favor of individual behavior assessments. As of early 2026, the PPP list is still in effect. Cats have no breed restrictions.

Airline Rules for Flying Pets to Spain

Country rules and airline rules are separate. Meeting Spain's import requirements doesn't guarantee your airline will accept your pet. Airlines add their own restrictions on top.

Iberia

Spain's national carrier flies direct from several US cities to Madrid:

• Cabin (transatlantic): $215 direct / $235 connecting. Max 8 kg including carrier. Carrier max: 45 x 35 x 25 cm (sum of dimensions must not exceed 105 cm)
• Hold (transatlantic): $330–455, depending on pet weight (up to 10 kg: $330 direct; 11–25 kg: $355; 26–45 kg: $390). Connecting flights cost $55–65 more
• Flat-faced breeds and breeds on Spain's PPP list are banned from the hold. They can fly cabin if under 8 kg
• Book through Iberia's Booking Offices at least 48 hours before departure
• Three small pets of the same species can share one carrier in the cabin. The fee is per carrier, not per pet
• Hold pets are not accepted on Iberia flights to/from Boston, Washington, San Juan, Recife, or Fortaleza

Delta and United

Delta: $200 each way for cabin pets on international flights. Carrier max: 18 x 11 x 11 inches.

United: $200 each way for cabin pets on international flights. Carrier max: 18 x 11 x 11 inches.

All airlines require pets to be at least 15 weeks old for EU travel. Call your airline 3–4 weeks before travel to reserve a pet spot. Most flights limit cabin pets to 2–4 per aircraft. For more airline details, see our airline fee comparison.

Cost Breakdown

Spain's entry rules are identical for dogs and cats. The cost difference comes from US re-entry requirements and whether your pet flies cabin or hold.

Cabin Travel (One Way)

Hold Travel (One Way)

Cost Saver

Iberia lets you put up to three small pets of the same species in one cabin carrier. You pay one fee ($215) for all three. If you're traveling with two small cats or two small dogs that share a carrier, that's half the per-pet cost of Delta or United.

Timeline

6–8 weeks before: Confirm your pet's microchip is ISO 15-digit. If no chip, get one implanted now. If your pet needs a rabies vaccine (first-time or lapsed booster), get it at the same visit, after the microchip. The 21-day clock starts at vaccination.

4 weeks before: Call your airline to reserve a pet spot. Book early because cabin spots fill up fast on transatlantic routes to Madrid and Barcelona. If your dog is a PPP breed, buy a muzzle now and let your dog get used to wearing it before travel.

10 days before (at most): Schedule your USDA-accredited vet appointment. The vet examines your pet, confirms the microchip number, reviews rabies records, and fills out the EU health certificate.

7–8 days before: Send the signed health certificate to your regional USDA endorsement office by overnight mail. Or drive there for same-day endorsement. You need the endorsed certificate back in your hands before you fly.

1–2 days before: Confirm your airline reservation for the pet. Print all documents. Pack originals in a waterproof folder in your carry-on.

Travel day: Arrive at the airport 60–90 minutes earlier than usual. The airline checks your pet's health certificate and endorsement at the counter. In Spain, present your pet and documents to customs at the border inspection post.

Common Mistakes

Airport Tips

Departing the US: Check in at the airline counter, not a kiosk. The agent needs to review your endorsed health certificate and rabies records before issuing a boarding pass. Iberia staff will fill out an official IATA form at check-in. For cabin pets, your carrier counts as your personal item on most airlines. For hold pets, drop off the crate at the oversized baggage area after document review.

Arriving in Spain: Follow signs to customs and declare that you're traveling with a pet to the Guardia Civil Fiscal Control Unit. A customs officer checks your health certificate, confirms the microchip number with a scanner, and reviews vaccine records. If your dog is a PPP breed, have the muzzle ready. If everything matches, you're through in 10–15 minutes.

Madrid-Barajas specifics: Most US flights land at Terminal 4. The veterinary inspection area handles pet arrivals regularly. If you're connecting to another EU country, Spain is your point of entry for customs clearance. After that, your pet can travel freely within the EU on the same health certificate for 4 months.

Returning to the US

Dogs

Spain is a CDC low-risk country for dog rabies. Returning is straightforward:

• Complete the CDC Dog Import Form online before your return flight. It's free. Save the receipt
• Dog must have a microchip readable by a universal scanner (you already have one from Spain's entry requirements)
• Dog must be at least 6 months old
• Dog must appear healthy on arrival
• Show the CDC form receipt to your airline before boarding and to US Customs on arrival

No screwworm certificate needed (Spain is not screwworm-affected). No separate US health certificate needed for re-entry from low-risk countries.

Cats

Federal re-entry rules for cats are minimal:

• Cat must appear healthy on arrival. That's the main CDC requirement
• No CDC import form (the Dog Import Form is dog-specific)
• No federal microchip requirement for US re-entry
• No screwworm certificate

Your cat already has a microchip and rabies vaccine from the Spain entry process. Keep those records for your own files, but US customs doesn't check them federally. Check your home state's rules; many states require rabies vaccination for cats, and Hawaii quarantines all arriving cats.

For more details on both species, see our guide to re-entering the US with a pet.

FAQ

Your next step: Book a USDA-accredited vet appointment 7–10 days before your flight. That's the bottleneck that controls your entire timeline.
