Travelling with Dogs in and out of the UK: What Has Changed Since Brexit
If you are planning to travel abroad with your dog from the UK, the rules that apply are significantly different from those that existed before Brexit. The EU Blue Pet Passport that many UK owners once relied upon is no longer valid for dogs travelling from Great Britain. Understanding the current framework is essential before booking any trip, because getting the paperwork wrong can result in your dog being refused entry or placed in quarantine on return.
The UK Pet Travel Scheme
Great Britain now operates under its own UK Pet Travel Scheme, which replaced the EU pet passport system for dogs, cats, and ferrets leaving from England, Scotland, and Wales. Dogs travelling under this scheme require an Animal Health Certificate (AHC) issued by an Official Veterinarian (OV) no more than ten days before travel. This certificate is single-use and destination-specific, so you will need a new one for each trip.
Northern Ireland operates under slightly different rules due to the Windsor Framework, so owners based there should check the specific requirements that apply to their situation before travelling.
Microchip First: The Rule You Cannot Ignore
Every dog travelling internationally must be microchipped, and the order in which this is done matters enormously. Your dog must be microchipped before its rabies vaccination is administered. If the rabies vaccine is given first and the microchip is implanted afterwards, the vaccination record will not be considered valid, and you may need to restart the process from scratch.
Ensure your dog's microchip number is recorded correctly on all documentation. The chip must comply with ISO standard 11784 or 11785 and must be readable with a standard scanner.
Rabies Vaccination Requirements
A valid rabies vaccination is required for all dogs travelling from the UK to most international destinations, and also for re-entry into the UK. Your vet must record the vaccination against your dog's verified microchip number. Most rabies vaccines require a booster after the initial primary course, and ongoing boosters are required to maintain valid status — your vet will advise on the specific schedule based on the product used.
If your dog's rabies vaccination has lapsed and you need to re-vaccinate, be aware that some destinations require a waiting period before travel is permitted following a new vaccination.
Titre Testing for Re-entry from High-Risk Countries
If you are travelling to a country that is classified as a rabies high-risk country — which includes much of Asia, Africa, and parts of Central and South America — your dog will need to undergo a rabies antibody titre test before it can re-enter the UK. This blood test confirms that your dog has a sufficient level of rabies antibodies following vaccination.
The titre test must be carried out at an EU-approved laboratory, and the result must show a level of at least 0.5 IU/ml. Importantly, the test cannot be done immediately before travel — there is a waiting period that must be observed, so planning well in advance is critical. Speak to your vet at least three months before travel if you intend to visit a high-risk country.
Tapeworm Treatment for Re-entry from the EU
When returning to the UK from an EU member state or certain other listed countries, your dog must be treated against tapeworm before re-entry is permitted. Specifically, your dog must receive a treatment containing Praziquantel, administered by a vet, no less than 24 hours and no more than 120 hours before the scheduled arrival time in Great Britain.
The treatment must be recorded in your dog's Animal Health Certificate or official travel document by the administering vet. This rule exists because the UK is currently free from the Echinococcus multilocularis tapeworm, which is present in parts of continental Europe and poses a risk to both animal and human health.
Travelling by Air: Cabin Versus Cargo
Whether your dog can travel in the cabin with you on a flight depends entirely on the airline and is governed by weight and size limits that vary significantly between carriers. Most UK and European airlines do not permit dogs in the passenger cabin, with the exception of recognised assistance dogs. Small dogs in approved carriers may be accepted in the cabin by some airlines, but this is the exception rather than the rule.
Larger dogs typically travel in the cargo hold, either in the pressurised and temperature-controlled baggage compartment or as manifest freight. While the hold environment is generally safe, there are important considerations:
- Brachycephalic breeds (such as French Bulldogs, Pugs, and Boxers) are banned by many airlines from cargo travel due to their risk of respiratory distress in stressful conditions.
- Extreme temperatures at origin or destination airports may lead airlines to refuse carriage under their live animal embargoes.
- Approved IATA-compliant travel crates are required, with specific size and ventilation requirements based on your dog's measurements.
- Some airlines have stopped transporting pets in cargo altogether, so always verify with your carrier before booking.
In cabin travel, where permitted, tends to be less stressful for dogs because they remain close to their owner. However, the dog must remain in its carrier under the seat throughout the flight, which can be uncomfortable for anything other than very small breeds on short routes.
Key Steps Before You Travel
- Confirm your dog is microchipped and that the chip number is registered correctly.
- Ensure the rabies vaccination was given after the microchip was implanted.
- Book an appointment with an Official Veterinarian for your Animal Health Certificate no more than ten days before departure.
- If visiting a high-risk country, arrange a titre test well in advance and confirm waiting period requirements.
- Schedule tapeworm treatment with a vet within the 24-120 hour window before returning from the EU.
- Contact your airline to confirm their specific live animal policy and crate requirements.
Pet travel requirements change, and the rules differ depending on your destination and your point of departure. Always verify current guidance with the UK Government's official pet travel pages and speak to your vet well in advance of any planned trip. Leaving preparations to the last minute is the most common reason dogs are prevented from travelling.
