Shipping a Pet Between the US and UK: The Complete Guide

Let’s discuss shipping a pet from the US to the UK. Moving between the United States and the United Kingdom with a pet is one of the more complex international relocations a pet parent can undertake. The UK has strict biosecurity rules designed to keep rabies out of the country, which means the documentation requirements and timelines are more demanding than most other destinations. The good news is that with the right preparation. And enough lead time. Pets make this journey safely every day.

This guide covers everything you need to know about shipping a pet from the US to the UK, and from the UK back to the US, including exact requirements, timelines, approved routes, and how to avoid the most common costly mistakes.

How far in advance do I need to start?

For US to UK pet moves, start at least 4 months in advance — and ideally longer. The UK’s entry requirements include a rabies antibody titer test that must be done at an approved laboratory, and the results must be at least 30 days old before your pet can enter the UK. That 30-day waiting period alone rules out any last-minute arrangements.

Here’s a realistic timeline working backwards from your travel date:

Step-by-step: US to UK pet entry requirements

Step 1 — Microchip

Your pet must be microchipped with an ISO 11784/11785 compliant 15-digit microchip before the rabies vaccination is given. If the chip was implanted after the vaccination, the vaccination does not count and must be repeated. This sequencing error is one of the most expensive mistakes pet parents make.

Step 2 — Rabies vaccination

Your pet must have a current rabies vaccination, administered after microchipping. The UK accepts rabies vaccinations given from 12 weeks of age. Keep the original vaccination certificate — you’ll need it for the health certificate and at the border.

Step 3 — Rabies antibody titer test

At least 30 days after the rabies vaccination, your pet must have a blood titer test showing a rabies antibody level of at least 0.5 IU/ml. The test must be conducted at a UK government-approved laboratory. In the US, approved labs include Kansas State University Veterinary Diagnostic Laboratory. Your vet draws the blood and sends it to the lab — results typically take 1–2 weeks.

Once you have a passing result, your pet must wait an additional 30 days before entering the UK. If the result is already on file and more than 30 days old, this waiting period is already satisfied.

Step 4 — Tapeworm treatment (dogs only)

Dogs entering the UK from the US must be treated for tapeworm (Echinococcus multilocularis) by a licensed veterinarian. The treatment must be given between 24 and 120 hours before arrival — not before, not after. The vet must record this in your pet’s documentation. Cats are exempt from this requirement.

Important: The tapeworm treatment window is the most commonly missed requirement for US-UK dog moves. It cannot be done early, cannot be done at home, and must be documented by a licensed vet. Missing this window means your dog cannot enter the UK on that travel date.

Step 5 — Health certificate

Within 10 days of travel, a USDA-accredited veterinarian must complete an official health certificate for UK entry (APHIS 7001 or equivalent). This must then be endorsed by USDA APHIS before travel. Endorsement typically takes 1–3 business days but can be expedited. The 10-day window moves fast — plan accordingly.

Step 6 — Approved entry points

Your pet must arrive in the UK through an approved port or airport. Not all UK airports accept pet arrivals. Approved entry points for pets arriving from the US include London Heathrow (most common) and Manchester. Always confirm your arrival point is approved before booking flights.

No quarantine — if you’ve done everything right

Pets that meet all UK entry requirements do not face quarantine. The UK Pet Travel Scheme allows compliant pets to enter without being held. However, if any single requirement is not met — wrong microchip sequence, lapsed titer test, missed tapeworm window — your pet can be refused entry or placed in quarantine at your expense. UK Border Force checks documentation thoroughly.

Bringing a pet from the UK to the US

The requirements for bringing a pet from the UK into the United States are generally less demanding than the reverse, but there are still important steps to follow.

Dogs entering the US from the UK

All dogs must arrive at one of 18 CDC-approved US airports. Since the UK is not classified as a high-risk rabies country, dogs that have only been in the UK are not subject to the same titer test requirements as dogs arriving from higher-risk regions. Dogs should appear healthy upon arrival and carry microchip documentation. Always confirm current CDC rules directly before travel, as requirements have changed in recent years.

Cats entering the US from the UK

Cats entering the US from the UK face fewer federal restrictions. There is no federal requirement for a health certificate for cats arriving from the UK, though airlines will typically require one. Cats should be up to date on vaccinations and have a microchip for identification.

State-level requirements

Individual US states may have their own import requirements on top of federal rules. If you’re landing in one state and traveling to another, check the destination state’s requirements. Some states require a Certificate of Veterinary Inspection (CVI) for incoming pets.

Flying your pet on US-UK routes

• In-cabin travel: Almost no transatlantic airlines allow pets in the cabin on US-UK routes due to flight length. In-cabin options are rare and typically limited to service or assistance animals.
• Cargo hold: Most pets travel in the temperature-controlled, pressurized cargo hold. Airlines that have historically transported pets on US-UK routes include British Airways (via its cargo arm) and Virgin Atlantic — but policies change frequently. Always confirm directly with the airline at the time of booking.
• Flight nanny or manifest cargo: Often the best option for US-UK moves. A professional handles documentation at both ends and ensures nothing is missed. Look for IPATA-accredited international pet shipping providers on PetWorks with specific UK entry experience.

Breed restrictions for UK entry

The UK prohibits certain breeds under the Dangerous Dogs Act 1991, including Pit Bull Terriers, Japanese Tosas, Dogo Argentinos, and Fila Brasileiros. Mixed-breed dogs that resemble a prohibited type may be detained for assessment by UK Border Force. If your dog’s breed is at all ambiguous in appearance, research this carefully before booking.
