Pet Transport from the United States to the United Kingdom – Rules and Documents

Required Documents

Which Health Certificates Are Actually Required?

EU Animal Health Certificate

EU certificate models changed in 2026. For travel on this route, the applicable form must be selected according to the travel date and whether the movement is non-commercial or commercial.

Select the current EU certificate through USDA APHIS

Great Britain Pet Health Certificate

The correct Great Britain certificate depends on whether dogs are included, the number of pets, the five-day relationship to the owner’s journey, and whether ownership will change.

Select the correct Great Britain certificate through USDA APHIS

Both certificates, where both are required, are separate official documents. The information in them must agree with the microchip and rabies records, the owner’s declaration and the actual route.

USDA APHIS Endorsement

A certificate signed only by an ordinary veterinarian is not sufficient. It must be completed by a USDA-accredited veterinarian and then endorsed by USDA APHIS, unless it was issued under the limited military-veterinarian exception recognised by USDA.

• For non-commercial travel, APHIS endorsement must fall within the applicable 10-day entry period.
• The original endorsed document package must accompany the pet.
• The owner or authorised person must complete the declaration contained in the non-commercial certificate.

Microchipping

Microchipping is mandatory for both dogs and cats. The microchip should comply with ISO 11784/11785 standards and must be implanted or read on or before the date of the rabies vaccination used for travel. If a non-ISO microchip is used, the owner may need to provide a compatible reader.

Rabies Vaccination

Rabies vaccination is mandatory for both dogs and cats. After a primary vaccination, the pet must complete the required immunity period before entry. This is at least 21 days, but the vaccine manufacturer may specify a longer period. A booster given before the previous vaccination expires does not restart the waiting period.

Rabies Antibody Titer Test

Mandatory Deworming (Dogs Only)

All dogs must undergo treatment for tapeworm (Echinococcus multilocularis) before entry into the UK:

• Treatment must be given 24–120 hours (1–5 days) before entry.
• The product must contain praziquantel or another pharmacologically active substance proven effective against Echinococcus multilocularis.
• The product name, manufacturer, date, exact time and veterinarian’s details must be clearly recorded in the Great Britain health certificate.
• Without proof of deworming, dogs will not be allowed entry into the UK.
• Cats do not require deworming.
• For entry into France and most other EU countries, this treatment is not an EU entry requirement. It is nevertheless required for the later entry into Great Britain, so its timing must be calculated from the scheduled arrival in Great Britain, not from arrival in France.

Fitness to Travel and Airline Documents

The official veterinary certificate confirms the pet’s fitness to travel. A separate “fit-to-fly” certificate is not a universal UK or EU legal requirement, but an airline may request its own health form or examination within a specific period. This must be checked with the operating carrier rather than assumed to be part of the border document package.

Transport Conditions

Number of Pets: A non-commercial movement is normally limited to five dogs, cats or ferrets. More than five requires the commercial procedure unless the animals are more than six months old, are travelling for an eligible competition, exhibition, sporting event or training, and the required evidence is available.

Minimum Age for Travel:

• In ordinary cases, puppies and kittens cannot enter until they are at least 15 weeks old: vaccination cannot be given before 12 weeks of age, followed by the required immunity period.
• If the vaccine manufacturer specifies an immunity period longer than 21 days, the actual earliest travel date will be later.

Transport: The route and carrier must be authorised for pet entry into Great Britain. Airline carriage conditions, including carrier dimensions and any additional airline health paperwork, are separate from the veterinary border requirements.

➕ Common mistakes in pet travel documents from the USA to the United Kingdom

Errors on this route are often caused not by a missing vaccination, but by choosing the wrong certificate or calculating the document timing from the wrong stage of the journey.

• Only one certificate is prepared for a route entering the EU before Great Britain. Entry into France followed by road travel requires an EU document for the EU stage and a separate Great Britain document for the UK stage.
• The certificate is signed by a veterinarian who is not USDA-accredited, or it is not endorsed by APHIS. A clinic’s signature alone does not complete the official export document.
• The wrong certificate category is selected. The non-commercial certificate cannot be used when the pet travels more than five days before or after the owner, when ownership changes, or where the applicable number-of-pets limit is exceeded.
• The microchip and rabies sequence is recorded incorrectly. The microchip must be implanted or read on or before the vaccination used for travel, and the same number must appear throughout the document package.
• The tapeworm window is calculated from arrival in France rather than entry into Great Britain. For dogs, the 24–120-hour period relates to the scheduled time of entry into the UK.
• Names, dates or identification details do not match. Differences between the rabies certificate, EU certificate, Great Britain certificate, owner declaration and booking can stop the journey even when the veterinary procedures themselves were performed correctly.
• An airline “fit-to-fly” form is treated as a replacement for the official certificate. Airline paperwork and border veterinary documents serve different purposes.

The safest point to correct these errors is before USDA APHIS endorsement. Once the documents have been endorsed and the travel window has started, the available time for correction may be very limited.
