Last verified: October 2026. EU pet travel certificates change on 1 October 2026. Confirm current requirements with USDA APHIS and Portugal's DGAV before booking anything.
Good news first: moving a pet from the US to Portugal is one of the easier international pet moves there is. No titer test. No quarantine. Most families are ready to travel in two to three months, against the six to eight months a country like Australia demands.
The difficulty isn't complexity — it's sequencing. Every step depends on the one before it, and one document expires ten days after it's issued.
The certificate changed this year
The EU replaced its pet movement framework in 2026 under Regulation (EU) 2026/131, applicable from 22 April 2026.
The new non-commercial health certificate has been mandatory since 1 October 2026, and the commercial certificate since 17 October 2026. Certificates issued on the older form are no longer accepted.
Your USDA-accredited vet will be using the current form, but it's worth confirming when you book.
No titer test — and this trips people up
A rabies antibody titer test (RNATT or FAVN) requires a blood draw 30 days after vaccination, then a 90-day wait before travel. It's the single biggest delay in international pet moves.
US pets don't need it. The United States is a "listed" third country under EU rules, appearing by name in Annex II of Implementing Regulation (EU) 2026/636. Microchip and valid rabies vaccination are enough.
A lot of general "moving pets to Europe" content still describes the titer process, because it applies to pets from unlisted countries — much of Africa, Brazil, Venezuela, Ukraine. If a guide tells you to budget six months and do a blood test, it isn't written for someone flying from the US.
The sequence — order is everything
1. Microchip first. ISO 11784/11785-compliant: 15 digits, non-encrypted.
This must happen before the rabies vaccination. If your pet was vaccinated before being chipped, the vaccination doesn't count and has to be repeated after the chip goes in. This is the most common and most expensive mistake.
If your pet has an older non-ISO chip — a 9-digit AVID, for instance — you either travel with a compatible scanner, or have a second ISO chip implanted. If you add a second chip, both numbers must appear on the health certificate.
2. Rabies vaccination, administered after the microchip, by a licensed vet. Your vet should scan the chip before vaccinating.
3. Wait 21 days from the vaccination date before travel. Not 21 days before the certificate — 21 days before the pet flies.
4. EU health certificate, issued by a USDA-accredited veterinarian. Not every vet is accredited; check before booking the appointment.
5. USDA endorsement. The certificate must be endorsed by USDA APHIS. Some states process electronically; others require physical submission. Build in time.
6. Notify Portugal's Point of Entry at least 48 hours before arrival. More on this below.
The ten-day window
The health certificate is valid for ten days from the date of issue, and must still be valid when your pet lands in Portugal.
That's the tightest constraint in the whole process, and it has to be coordinated with your vet appointment, USDA endorsement turnaround, and your actual flight. Miss the window and the certificate is void.
