The dog travel guide that starts from the specific reality: travelling with a dog is significantly more logistically complex than travelling without one, and the complexity is not proportional to the size of the dog. The passport, the microchip, the rabies vaccination, the tapeworm treatment timing (the specific 24-120 hour window that the rules require and that the timing of the return trip must be planned around), the airline cabin carrier dimensions (the specific 45cm × 28cm × 25cm maximum that the budget airline enforces and that the 6kg Cocker Spaniel does not fit within at any angle), and the specific countries that the UK passport dog can enter and that will let you both back in are the specific information this guide provides.

The UK Pet Travel Scheme (Post-Brexit)
The UK left the EU Pet Travel Scheme in 2021. The UK is now listed as an “unlisted third country” under the EU pet travel rules — the same category as the US, the Australia, and most non-EU countries. This means:
To take your UK dog to the EU: The microchip (ISO 11784/11785 compliant), the valid rabies vaccination (at least 21 days before entry), and the EU health certificate (the Animal Health Certificate — the AHC, issued by the UK government-authorised Official Veterinarian, valid 10 days from issue for entry, 4 months for the trip duration) are required. The AHC must be issued no more than 10 days before the EU entry date.
To bring your dog back from the EU to the UK: The tapeworm treatment (the Praziquantel treatment, administered by the vet 24-120 hours before arrival in the UK — the specific timing window that makes the return trip logistics critical) and the AHC (the same document issued by the vet at the destination, valid for the return).
The Northern Ireland exception: Northern Ireland follows the EU pet travel rules (the Northern Ireland Protocol) — travelling from Great Britain to Northern Ireland with a dog requires the same documentation as travel to the EU.
The Airline Rules
Cabin travel (the preferred option for small dogs):
The cabin-approved carrier dimensions vary by airline — the specific dimensions below are correct for the most common UK departure airlines (verify before booking — dimensions change):
- Ryanair: No pets in cabin
- easyJet: No pets in cabin
- British Airways: Cabin pets not permitted on UK flights (the US routes allow service animals only)
- Jet2: No pets in cabin
- KLM: Cabin pets permitted (max combined weight dog + carrier: 8kg, carrier max dimensions 46cm × 28cm × 24cm)
- Lufthansa: Cabin pets permitted (max combined weight: 8kg, dimensions 55cm × 40cm × 23cm)
The specific UK route reality: The majority of UK airlines do not permit pets in cabin on domestic or international routes. The ferry and the Eurotunnel (Le Shuttle) are the primary UK dog-travel options for European destinations — full detail below.
The Ferry and Eurotunnel Option
Le Shuttle (Eurotunnel, Folkestone-Calais): Dogs travel in the car with the owner. The car is loaded onto the train; the owner remains in the car for the 35-minute tunnel crossing. The dog documentation (the AHC, the microchip confirmation, the rabies vaccination record) is checked at the Folkestone terminal. This is the most convenient single-journey option for the UK dog owner travelling to France and beyond.
The ferries (DFDS, P&O, Brittany Ferries): Dogs are permitted in the pet-designated cabin or in the kennel on the car deck depending on the route and the operator. The Brittany Ferries Plymouth-Roscoff route (the 6-8 hour overnight crossing) is the most dog-friendly UK ferry — the pet cabin (the cabin where the dog sleeps with the owner) is available on this route.
The Countries That Will Let You Back In
The re-entry to the UK is the specific constraint that limits the dog travel destination:
The UK permits entry of dogs from all countries, subject to the documentation (the microchip, the rabies vaccination, and the AHC or the equivalent country-specific documentation). However, the rabies-free countries (the UK, Ireland, Australia, New Zealand, Japan, Hawaii, and several other island nations) have the specific re-entry requirements that the rabies-endemic country destination triggers.
The specific Australia and New Zealand note: Taking a UK dog to Australia or New Zealand is possible but requires the specific import process (the 10-day quarantine in Australia, the longer quarantine in New Zealand) that makes the holiday trip impractical. These are destinations for the person relocating permanently, not travelling.
The Practical Dog Travel Checklist
- Microchip (ISO standard) — done before the vaccination
- Rabies vaccination — at least 21 days before EU entry
- Animal Health Certificate — issued no more than 10 days before travel, by the government-authorised Official Veterinarian (find at gov.uk/find-government-approved-official-vet)
- Tapeworm treatment — for the return to the UK, 24-120 hours before the UK arrival
- Travel insurance — the dog-specific travel insurance (the Agria, the PetPlan Travel Cover) covering the emergency vet costs abroad
