SHORT ANSWER
Moving a pet from the United States to Portugal is far simpler than moving one to a rabies-free country like Australia, but it still runs on a strict European Union clock. Your dog or cat needs a microchip implanted before any rabies vaccination, a rabies shot given at least 21 days before travel, and either a "non-commercial" or "commercial" EU health certificate issued by a USDA-accredited veterinarian and endorsed by USDA. Because the United States is not on the EU's rabies-risk country list, there is no antibody titer test and no 90-day or 180-day waiting period involved. Owners must also file a mandatory arrival notice with Portuguese authorities at least 48 hours before landing, and pets can only enter at designated Points of Entry, currently Lisbon and Porto. Most families can complete the process in two to four months, well short of the six-to-eight-month runway required for rabies-controlled destinations.
If your pet-owning clients have researched moving to Australia before turning to Portugal, the contrast can feel almost too good to be true. Portugal is a European Union member state, and the EU's non-commercial pet movement framework was built for exactly this kind of transatlantic move: a microchip, a rabies vaccine, a health certificate, and a waiting period measured in weeks, not months. There is no mandatory post-arrival quarantine for a pet that meets the requirements, no antibody titer test for pets coming from the United States, and no six-figure biosecurity bureaucracy to wade through.
That simplicity, combined with Portugal's cost of living, weather, and two relatively new visa pathways for Americans (the D7 visa for retirees and passive-income earners, and a newer digital nomad visa for remote workers), has turned Portugal into one of the fastest-growing pet relocation destinations Starwood tracks. Inquiries for US-to-Portugal pet moves increased roughly 11 times between 2021 and 2025, according to data shared by Global Pets, Starwood's destination-side partner in Portugal, on the Pet Travel Insider Podcast.
Still, "simpler than Australia" does not mean "simple." Portugal applies its own interpretation of the EU rules on top of the baseline EU regulation, and getting even one date or document out of sequence can turn a smooth arrival into a very long day at Lisbon's cargo terminal.
Every pet entering the EU needs a working, ISO-compliant microchip (ISO 11784 and 11785 standards, typically a 15-digit number). The order of operations matters more than almost anything else in this process: your veterinarian must scan the microchip before administering the rabies vaccine. A rabies vaccination given before the microchip was implanted, or without the microchip being scanned first, does not count under EU rules, according to Portugal's Direção-Geral de Alimentação e Veterinária (DGAV), the government agency that regulates pet imports. If that happens, the rabies vaccine has to be repeated after the microchip is in place, and the waiting period starts over.
If your pet already has a microchip that isn't ISO-compliant, you have two options: travel with your own scanner capable of reading it, or have a second ISO-compliant microchip implanted. Either way, both microchip numbers need to be listed on the health certificate.
Once the microchip is in, the rabies vaccination clock starts. Under EU rules, a rabies vaccination is classified as either "primary" or "booster," and the distinction changes your timeline significantly, according to the USDA Animal and Plant Health Inspection Service (APHIS) guidance for pet travel to Portugal.
A primary rabies vaccination is the first one your pet receives after microchipping, or the first one after any lapse in coverage. For pets vaccinated in the United States, a primary vaccination is only valid for one year, even if the vaccine itself is a three-year formulation. Pets must wait at least 21 days after a primary vaccination (or longer, if the manufacturer specifies a longer immunity period) before traveling to Portugal.
A booster rabies vaccination, given within 12 months of the primary shot, can be valid for one to three years depending on the manufacturer, and does not require a new 21-day wait, as long as there was no lapse in coverage. If your pet already has an up-to-date rabies vaccination history from routine care in the United States, this can shave weeks off your timeline. If your pet is unvaccinated or overdue, plan for the full 21-day wait after a fresh primary vaccination.
Unlike destinations with high rabies risk, the United States is not on the EU's list of high-risk countries (which includes much of the African continent, Brazil, Venezuela, and Ukraine, among others). That means US pets skip the antibody titer test and the 90-day post-titer waiting period those countries require. This is the single biggest reason a Portugal move typically takes a fraction of the time an Australia move does.
This is where a lot of avoidable mistakes happen. The EU has two versions of the pet health certificate, and which one you need depends entirely on your own travel dates, not just your pet's.
Non-commercial health certificate. Use this if you, or a person you've designated in writing, are traveling within five days before or after your pet, and you're moving five or fewer pets. The non-commercial certificate is issued by a USDA-accredited veterinarian, is valid for 30 days from issuance, and must be endorsed by USDA. Your pet must then arrive in the EU within 10 days of that USDA endorsement.
Commercial health certificate. You must use this version if neither you nor a designated person can travel within five days of your pet, or if you're moving six or more pets. Commercial certificates carry a much tighter window: the accredited veterinarian must examine your pet and issue the certificate, and USDA must endorse it, within 48 hours of your pet's departure from the United States.
A few details that trip people up on the non-commercial certificate: only the legal owner's name can appear on it, even if a friend or family member is the one actually traveling with the pet (in which case you'll need a signed written authorization attached to the certificate). And if your pet travels separately from you, outside that five-day window, Portuguese customs will treat the movement as commercial and apply commercial import fees and processing timelines, regardless of your original intent.
If you're planning a move for later in 2026, there's a regulatory change worth building into your timeline now. New EU legislation, Regulation (EU) 2026/131 for non-commercial pet movement and Regulation (EU) 2026/848 for commercial movement, came into effect April 22, 2026. Both regulations include a transition period for the paperwork itself, according to USDA APHIS and confirmed by DGAV.
The current non-commercial health certificate can still be endorsed through September 30, 2026, and the new version becomes mandatory starting October 1, 2026. The current commercial certificate can be endorsed through October 16, 2026, with the new version taking over on October 17, 2026. DGAV notes a further transition allowance: certificates issued under the older Regulation (EU) 577/2013 format that were endorsed before October 1, 2026 remain valid for movement through March 31, 2027.
Practically, this means a pet move planned for September 2026 will use the current paperwork, while a move planned for November 2026 will need the new certificate format. If your travel date falls close to either cutoff, confirm with your USDA-accredited veterinarian which version applies before you schedule anything else.
Portugal requires owners, not airlines or transport companies, to notify the destination Point of Entry for Travellers at least 48 hours before arrival, using DGAV's official arrival notice form. This is separate from your health certificate and is one of the most commonly missed steps, according to Starwood's Portuguese import partner, Global Pets. Sending the form to the wrong email address, or skipping it altogether, can hold up your pet's release even when every other document is in order.
Currently, only two airports are authorized Points of Entry for pets arriving from outside the EU: Lisbon and Porto. Both have overnight closures for the veterinary control point, according to DGAV: Lisbon's is closed between midnight and 6:00 a.m., and Porto's between 11:00 p.m. and 7:00 a.m. A flight arriving during those windows will need to wait for the point of entry to reopen before your pet can be released, so it's worth checking your specific arrival time against these hours before booking. There is also a standard veterinary exam fee at the point of entry (roughly 42 euros for one animal, or 85 euros for two or more), waived for certified assistance dogs.
"Families moving to Portugal tend to assume that because the EU process is shorter than Australia's, the details matter less. It's actually the opposite. Australia gives you six months to catch a paperwork mistake. Portugal can give you 48 hours. Get the arrival notice in early, and confirm your flight lands inside the point of entry's operating hours, because those two things alone prevent most of the delays we see." -- Adam Melton, VP of Strategic Initiatives, Starwood Pet Travel
Portugal allows dogs of seven breeds and their crosses to enter the country without a ban, but with an extra step: Cão de Fila Brasileiro, Dogue Argentino, Pit Bull Terrier, Rottweiler, American Staffordshire Terrier, Staffordshire Bull Terrier, and Tosa Inu. At the point of entry, owners of these breeds must sign one of two forms depending on how long the pet will stay in Portugal: a liability declaration for stays under four months, or a longer-term residency notification for stays beyond four months, according to DGAV. Dogs registered in an officially recognized pedigree book are exempt from this requirement, provided the owner can show proof.
It's worth separating this from a different, and sometimes more disruptive, issue: airline-specific breed restrictions for cargo or hold transport. Airlines maintain their own lists of breeds they won't accept in the cargo hold, often built around brachycephalic (short-nosed) or bully-type dogs, and those lists don't always line up with a country's own import rules. One pet owner who documented their move on Reddit described exactly this scenario, discovering at the airport that their dog, listed as a "Chihuahua mix," had been flagged against the airline's hold restrictions and needed a same-day letter from their vet confirming the dog was fit to fly. Confirming both lists, the destination country's and the airline's, well before travel day avoids a stressful surprise at check-in.
Firsthand accounts from pet owners who have actually made this move are some of the most useful planning resources available, precisely because they surface the small logistical details official guidance doesn't always spell out. In a detailed post to r/PortugalExpats, one owner who flew two Shetland Sheepdogs from Florida to Lisbon in the cargo hold walked through their entire process, including the paperwork, the crate setup, and the arrival experience: "There is a document on the DGAV website 'Form for Dogs and Cats' that is mandatory to be sent to the airport vet at least 48 hours before arrival, so they know when you are arriving... There is no appointment to make with the vet. You just have to wait in line after you arrive" (r/PortugalExpats discussion).
The same thread includes a useful reminder about keeping paperwork organized: the owner made three paper copies of every document, clearly marked "original" or "copy," and kept the true originals in a separate waterproof folder, a small habit that made the actual airport handoff go smoothly on both ends of the trip.
Because the rabies vaccination and the 21-day wait sit at the center of this process, most pets can be ready to travel within four to eight weeks of starting their paperwork, assuming their rabies vaccination history is current or nearly current. Add time for scheduling with a USDA-accredited veterinarian, getting the health certificate endorsed by USDA, and coordinating flights, and a two-to-four month runway is realistic for most US-to-Portugal moves.
That said, the pet is usually the fastest-moving part of a larger relocation. Diana da Costa of Global International Relocation, the parent company of Starwood's destination partner Global Pets, recommends that Americans without an existing EU passport start planning their broader move (visas, banking, housing, and household goods) roughly three months out, to avoid feeling rushed on the non-pet logistics.
