SHORT ANSWER
No. A dog or cat moving from the United States to Great Britain (England, Scotland and Wales) does not need a pet passport, and the US does not issue them. Instead, your pet enters on a Great Britain pet health certificate completed by a USDA-accredited veterinarian and endorsed by USDA APHIS within 10 days of arrival. That certificate is backed by an ISO microchip, a rabies vaccination given at least 21 days before travel and, for dogs, a tapeworm treatment given 1 to 5 days before arrival. Because the US is a “listed” country, no rabies blood test or quarantine is required when every rule is met.
A pet passport is a booklet issued by an authorized vet that records a pet’s microchip, rabies vaccinations and, for dogs, tapeworm treatments. The EU created it so pets can move between member countries without a new health certificate for every trip. According to GOV.UK’s guidance on pet passports, passports can only be issued in EU countries and a set list of others, including Switzerland, Norway, Iceland, Andorra, Monaco, San Marino, Gibraltar and several French overseas territories.
The United States is not on that list. A US vet cannot issue a pet passport, and the UK will not accept a US vaccination booklet or vet record as a substitute. On a recent episode of Pet Travel Insider, Adam Melton, VP of Strategic Initiatives at Starwood Pet Travel, put it plainly: for pets coming from the US, “they don’t really recognize pet passports in lieu of a health certificate.” He added that a passport “does not take the place of one of the health certificates, which is then endorsed by the USDA.”
There is also a technical reason a passport would not help even if you had one. GOV.UK states that for passports issued from 1 January 2021, vaccine details must be entered by a vet in a country that can issue pet passports. A rabies booster added by a US vet would not count.
The UK government groups the rest of the world into “listed” and “not listed” countries. The USA, including American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the US Virgin Islands, is a listed country. In the GOV.UK table of accepted travel documents, the only document listed for pets coming from the USA is the Great Britain pet health certificate.
USDA APHIS calls this the UK health certificate and offers two versions on its US to UK pet travel page:
| Certificate | Who it covers | Timing rule |
|---|---|---|
| Non-commercial | Up to 5 pets traveling within 5 days before or after the owner or an authorized person | Valid 30 days after the accredited vet signs it, but APHIS must endorse it within 10 days of arrival in the UK |
| Commercial | Pets traveling more than 5 days apart from the owner, 6 or more pets at once, or pets changing ownership or being sold | Issued and endorsed within 48 hours of departing the US |
Most families relocating with one or two pets use the non-commercial certificate. If your pet will fly more than 5 days before or after you, the commercial certificate and extra UK rules (known as Balai rules) apply.
Your pet needs an ISO 11784/11785 compliant microchip, which is 15 digits long. APHIS stresses that the implant date recorded on the health certificate must be on or before the date of the primary rabies vaccination. A rabies shot given before the chip is invalid for UK travel. If your pet has an older non-ISO chip, your vet can add an ISO chip, and both numbers go on the certificate.
GOV.UK requires proof that your pet was at least 12 weeks old at vaccination. After a primary vaccination, you must wait at least 21 full days before your pet arrives, counting the day after the shot as day 1. Some vaccines carry a longer manufacturer immunity period, such as 30 days, and that longer period applies.
APHIS adds a UK-specific rule many owners miss. The first rabies vaccine given after the microchip is treated as the primary vaccine and is valid for only 1 year for UK purposes. If your pet travels more than 12 months after that first post-chip shot, you need written proof of a booster given within those 12 months. Boosters given on time do not trigger a new 21-day wait.
Bring a hard copy of every rabies certificate. APHIS says each one must show the correct microchip number, the vaccine manufacturer and the full vaccine name, and all of it must match the health certificate.
Dogs must be treated for the Echinococcus multilocularis tapeworm by a USDA-accredited vet between 24 and 120 hours (1 to 5 days) before entering Great Britain. GOV.UK’s tapeworm rules require a product containing praziquantel or a proven equivalent. The vet records the product name, manufacturer, date and time on the certificate. Cats do not need this treatment.
Your USDA-accredited vet completes and signs the Great Britain pet health certificate, usually through APHIS’s electronic VEHCS system. APHIS then ink-signs and embosses it. For a non-commercial move, that endorsement must happen within 10 days of your pet’s arrival, which is why timing the final vet visit matters so much.
The last page of the non-commercial certificate is a declaration that you are not selling or transferring your pet. You sign it before travel and add the APHIS-assigned certificate number once the endorsement comes back.
For a pet that is already microchipped and current on rabies, preparation can fit inside a few weeks. Starting from scratch, the fastest legal path is roughly a month:
| When | What happens |
|---|---|
| Day 0 | Microchip implanted, then rabies vaccine the same day or later |
| Day 21 or later | Earliest arrival date after a primary rabies vaccine (longer if the vaccine label says so) |
| Within 10 days of arrival | Accredited vet issues the certificate and APHIS endorses it |
| 24 to 120 hours before arrival | Dog tapeworm treatment given and recorded |
| Arrival | Microchip and documents checked; pet cleared through customs |
Compare that to Australia or New Zealand, where a rabies titer test adds months. The UK does not require a rabies blood test for pets from the USA because it is a listed country. For a full country overview, see our Country Guide for the United Kingdom.
Only in a narrow set of cases. GOV.UK says a pet can enter Great Britain from outside the EU on a pet passport issued in Great Britain before 1 January 2021, or on a valid passport issued in an EU country or another passport-issuing country. In practice, that describes a pet that previously lived in Europe or the UK and still holds a valid passport with rabies details entered by a vet in a passport-issuing country.
As Adam Melton noted on Pet Travel Insider, most people moving from the US to the UK were never based in the EU, so they will not have a pet passport anyway. “And so really, it’s just not applicable,” he said. “It’s not something that is required at all.” Your pet proves its microchip and rabies status through the rabies certificate and the endorsed health certificate instead.
The paperwork is only half of entry. GOV.UK’s travel route guidance says pets must fly into Great Britain as cargo unless you are on a chartered private plane or traveling with a recognized assistance dog. You must also use an approved route and carrier, and those routes can change or run seasonally.
On arrival, officials check the microchip and documents. Pets entering from outside the EU must be cleared through customs before you can collect them, and GOV.UK notes that you can usually pay an agent, airline or travel company to handle this. APHIS also points owners flying into London Heathrow to a paperwork pre-check offered by the Heathrow Animal Reception Centre, which should be done before USDA endorsement.
One more check before you book: the UK bans ownership of the Pit Bull Terrier, Japanese Tosa, Dogo Argentino, Fila Brasileiro and XL Bully unless a valid Certificate of Exemption exists. Per GOV.UK, whether a dog counts as a banned type depends on what it looks like, not its breed name.
The passport question comes up constantly in UK expat forums. In an r/ukvisa thread about bringing pets from the USA to the UK, one commenter answered the confusion in a single line: “You need health certificates, not a pet passport” (r/ukvisa).
Another owner who posted a step-by-step outline of their own move in r/MovingToTheUK flagged the deadline that trips people up: “You will need a Vet appointment 10 days before the date of ARRIVAL in the UK” (r/MovingToTheUK). That 10-day window is the APHIS endorsement deadline, and it is measured from arrival, not departure.
As Georgiana Strait, Marketing Manager at Starwood Pet Travel, explains: “We hear from families every week who are trying to get a pet passport before their move to England. You don’t need one, and you can’t get one in the US. What actually gets your dog or cat through UK customs is a health certificate where the microchip, rabies and tapeworm details all match, endorsed by USDA inside that 10-day window. That is where your time and attention should go.”
