Moving a dog from Great Britain to France is no longer a simple pet-passport exercise. After Brexit, England, Scotland and Wales are treated as a third country for entry into the European Union. As at 28 August 2026, the framework has also changed: Regulation (EU) 2026/131 now supplies the animal-health rules for non-commercial movements, while Regulations (EU) 2026/636 and 2026/705 govern the country lists and document models. The practical essentials remain strict: a readable microchip, a rabies vaccination administered in the correct order, an original animal health certificate signed or endorsed by an official veterinarian, and presentation of the dog and documents at the travellers’ point of entry. Great Britain-issued pet passports do not normally replace that certificate. The United Kingdom’s own guidance and France’s customs guidance must be read together, especially if you intend to return. This article explains the legal classification, the date calculation, the evidence to carry, and the urgent response when a carrier or French authority refuses boarding, orders re-expedition, or threatens a more serious measure. The focus is a private relocation or journey with your own dog, not a sale, rehoming, breeding operation or commercial import.

I. Can I move my dog from Great Britain to France after Brexit?

A. Which legal route applies to a British owner moving to France?

The first question is not whether the dog is loved, insured or already registered with a British veterinary practice. It is whether the planned movement is legally non-commercial. A non-commercial movement is the route normally used by a British owner who is taking the owner’s own dog to a French home, without selling the dog or transferring ownership as part of the journey. The owner’s movement and the animal’s movement should form one coherent journey. A friend, family member or professional carrier may travel on the owner’s behalf only where the required written authorisation and supporting evidence are in place.

The distinction matters because “commercial” does not mean only a shipment made by a company for profit. A sale, a rehoming that transfers ownership, an import for later sale, arrival separated from the owner, or a movement exceeding the private-travel limits can take the case outside the simpler passenger procedure. The United Kingdom’s official guidance for travelling to an EU country expressly directs owners to different rules when there is a change of ownership or a commercial export. France’s customs guidance similarly asks whether the movement is without a commercial character and whether the maximum number of animals is respected.

For a private journey, the ordinary limit is five pets per owner or authorised person, subject to the specific event exception for certain dogs, cats and ferrets. If you intend to travel with six dogs, to deliver a dog to another household, or to have a transporter arrive without you, stop treating the journey as an ordinary family move. Obtain the commercial-import instructions before booking. An incorrect label can send the animal to a border control post that is not equipped for the intended species or route.

The current European framework is not the old “EU pet passport and 21 days” regime copied from a pre-Brexit checklist. Commission Delegated Regulation (EU) 2026/131 of 20 January 2026 supplements Regulation (EU) 2016/429 for non-commercial movements. It contains the rules for identification, rabies protection, documents, authorised persons and exceptional permits. Commission Implementing Regulation (EU) 2026/705 of 20 March 2026 supplies the model identification documents and declarations. Commission Implementing Regulation (EU) 2026/636 supplies the relevant country lists. These instruments apply alongside the French national rules that organise inspection and enforcement at the border.

French law begins with a broad rule. Article L. 236-1 of the Code rural et de la pêche maritime requires animals entering France to satisfy the health, quality and animal-protection conditions fixed by European rules or, within those rules, by the French agriculture minister. The same article contains a point often missed in household checklists: “Tout chien importé ou introduit sur le territoire national ne peut entrer que s’il dispose d’au moins une dent d’adulte.” In English, an imported or introduced dog must have at least one adult tooth. This is not a substitute for vaccination or an animal health certificate; it is an additional statutory condition that can matter for a young dog.

Great Britain and Northern Ireland must also be separated. A resident of England, Scotland or Wales travelling from Great Britain to France will generally need the Great Britain-to-EU route and an animal health certificate. Northern Ireland has a different practical position because EU pet-document rules can apply to travel from Northern Ireland. A British passport does not answer the question by itself: the relevant facts are where the dog is travelling from, where the document was issued, where the rabies vaccination was administered, and whether the dog has returned to the Union after a temporary stay.

The French control point is part of the legal analysis, not a final administrative formality. Article L. 236-4 of the Code rural et de la pêche maritime permits the control of travelling companion animals at an international port, airport, railway station or bus station and allows it to be limited to documentary and identity checks by customs officers. The statutory text says that “le contrôle peut être effectué dans tout port, aéroport, gare ferroviaire ou routière ouvert aux liaisons internationales” for the companion animals covered by the provision. The fact that the crossing is made by ferry or train does not make the check optional.

Situation	Initial legal question	Practical consequence
Private move with your own dog	Is the movement non-commercial, within the animal limit, and linked to the owner’s journey?	Prepare the microchip, rabies record, animal health certificate and entry-point presentation.
Sale, rehoming or transfer of ownership	Has ownership changed or will it change because of the journey?	Use the commercial-import route; do not rely on the private passenger certificate.
More than five pets or owner absent	Does the event exception or authorised-person route apply, with written proof?	Confirm the route and point of entry before travel; extra controls may apply.
Dog from Northern Ireland or temporary return to France	Does an accepted EU passport document the continuing rabies cover?	Check the re-entry exception; a booster given in Great Britain can change the document required.

There is a useful but limited lesson from the Cour de cassation, criminal chamber, 7 April 2021, appeals nos. 12-80.601 and 20-80.668. That case concerned the introduction and sale of puppies in a commercial setting, not a British family relocation. The Court considered the statutory and veterinary-document chain and recalled that a judgment must give reasons: “L’insuffisance ou la contradiction des motifs équivaut à leur absence.” The decision is not authority for ignoring a border rule. It is a warning that the exact documents, the person responsible for each statement, and the reasoning behind an enforcement decision can become decisive if the matter escalates.

B. Which documents and dates must be ready before the ferry or Eurotunnel?

Build the file backwards from the planned arrival in France. Do not begin with the animal health certificate appointment. Begin with the identity record and the rabies history, then calculate the waiting period, then arrange the certificate within its ten-day entry window. A document that is individually genuine may still fail as a sequence if the microchip was recorded after the vaccination, if a booster was late, or if the certificate is signed outside the permitted period.

First, the dog must be identifiable. The microchip number should be the same on the veterinary record, the vaccination entry, the animal health certificate and any passport that is being relied upon. The British government’s microchip guidance states that the chip must be implanted before, or at the same time as, the rabies vaccination. France’s customs page refers to ISO 11784 and ISO 11785 standards. If the chip cannot be read by the carrier or inspecting officer, take a compatible reader or resolve the identification problem before travel. A new chip may require a new vaccination record and a new waiting period; simply carrying a photograph of a number is not enough.

A tattoo can be accepted only in the narrow legacy situation: it must have been made before 3 July 2011, remain clearly legible, and be supported by the required record. For almost every current British relocation, the safest operational assumption is that a readable microchip is required. Ask the vet to scan it in front of you and place the number in every document before the certificate is signed. Record the scan date and the location of the chip if the form provides for it.

Second, the dog needs a valid rabies vaccination. The United Kingdom’s rabies vaccination guidance requires proof that the dog was at least twelve weeks old before the vaccination and states that the microchip must precede or accompany the vaccination. After a first vaccination, the owner must wait at least 21 full days; the day after vaccination is day one for that calculation. The vaccine must be authorised for the country in which it was administered and the veterinary record must show the date, product, batch, validity date, microchip details and veterinary signature.

That date calculation is the minimum planning rule, not permission to bring a very young puppy. France’s current customs information says that the introduction of dogs, cats and ferrets under sixteen weeks is not authorised. A first vaccination at twelve weeks followed by the waiting period may still leave a practical or legal age problem at the French border. For a young dog, take the dog’s date of birth, the vaccination date and the route to the official French and British authorities before paying for travel. A carrier can refuse boarding even where an owner has read only the vaccination interval.

Third, obtain the correct animal health certificate. The UK government’s official animal health certificate guidance requires the certificate before entry into the EU, limits its entry validity to ten days from issue, and requires signature by an official veterinarian. The visit should include proof of the microchip date and vaccination history. France’s customs page describes the original certificate as established or endorsed by an official veterinarian in the third country of origin and says that it is valid for ten days until the entry checks. Keep the original paper document with the dog. A scan in a phone, an email from the practice or a photocopy may support the file but should not replace the original.

One certificate can cover up to five pets where the route permits it. After the documentary and identity checks, the certificate can ordinarily support onward movement within the EU for up to six months, or until the rabies vaccination expires, whichever comes first. That longer period does not extend the ten-day window for entering France from Great Britain. It also does not create a permanent replacement for a new certificate on a later Great Britain-to-EU journey.

Fourth, do not use the wrong passport. A pet passport issued in Great Britain is not normally a valid entry document for an England-, Scotland- or Wales-based dog travelling to France. The French customs page states that, from Great Britain, the animal should travel with the original health certificate and vaccination evidence. A narrow reintroduction exception can apply where a dog already has an EU passport, leaves the Union temporarily, and has not received a rabies booster in Great Britain. If a booster was administered in Great Britain, the EU passport may no longer prove the required chain and a British health certificate may be required. Treat the document as a controlled legal record, not as a booklet that remains automatically valid after any veterinary intervention.

Fifth, understand the blood-test point. The United Kingdom is included in the current country framework that allows the rabies antibody-titration test to be dispensed with for qualifying non-commercial movements. France’s customs page expressly says that dogs, cats and ferrets coming from the United Kingdom are exempt from presenting a rabies antibody-titration result. That does not waive the microchip, vaccination, certificate, age, owner, number-of-animals or border-presentation requirements. A route through a country outside the relevant list can change the result. If the dog transits a non-listed country, preserve the signed declaration and proof that the animal had no contact with susceptible animals and remained secured as required by the applicable regulation.

Sixth, plan the return to Great Britain separately. The French entry procedure is not the British return procedure. For a dog returning to England, Scotland or Wales from France, the GOV.UK tapeworm-treatment guidance normally requires treatment against Echinococcus multilocularis between 24 and 120 hours before arrival, with the product, date, time, stamp and signature recorded in the travel document. France does not become a tapeworm-treatment-free route merely because the first crossing was legal. If your move involves a short trip or an emergency return, calculate the return window with the ferry, tunnel, delays and check-in time in mind.

Seventh, make the non-commercial evidence coherent. Carry the owner’s travel booking, the dog’s identification details, the signed authorisation if another person travels, proof that there is no sale or transfer, and a concise written timeline. If the dog is moving to the owner’s French home, retain the French address and the relocation documents. Those items do not replace health documents, but they can prevent a carrier or officer from treating the journey as a disguised commercial movement. Keep one paper pack and one electronic copy; do not edit a signed certificate after issue.

1. Confirm whether the departure point is Great Britain or Northern Ireland.
2. Confirm that the dog is moving without a sale or change of ownership.
3. Check the number of animals and whether an authorised person will travel.
4. Scan the microchip and compare the number across every record.
5. Verify that the rabies vaccination followed the chip and that the waiting period has ended.
6. Check the dog’s age, including France’s under-sixteen-week restriction in the current customs guidance.
7. Book an official veterinarian and obtain the original animal health certificate inside the ten-day entry window.
8. Confirm the travellers’ point of entry and the carrier’s document procedure.
9. Prepare the return-to-Great-Britain tapeworm plan before leaving.

Do not rely on an old article that cites only Regulation (EU) No 576/2013. The new 2026 instruments are particularly important for anyone preparing a move after 22 April 2026. The French customs page has also been updated to explain the new certificate models, the continuing treatment of Great Britain as a third country, the no-titration position, and the distinction between a return with an EU passport and a new departure from Great Britain. A responsible owner should print the current page and keep the date of the check in the travel file, while still treating the legal text as the controlling source.

II. What can I do if France refuses my dog at the border?

A. What happens after a carrier or French officer identifies a non-compliance?

Separate a refusal to board from a French border decision. A ferry or tunnel operator may prevent boarding because its staff cannot verify the chip or certificate. French customs may then carry out the documentary and identity check at the travellers’ point of entry. A veterinary border service may become involved where the dog does not qualify for the private companion-animal route or where a health condition requires a different control channel. Each event should be documented separately because the remedy, decision-maker and time pressure are different.

Ask immediately for the precise reason in writing. Request the document or record that identifies the missing page, wrong date, unreadable chip, incorrect passport, age problem, classification issue or non-approved point of entry. Note the name or service of the officer, the time, the location, the dog’s condition, the carrier’s instructions and the deadline for the next action. If staff state that “France refuses the dog”, that sentence is not enough to prepare a legal challenge. You need to know whether the actual decision is refusal of travel, a direction to present the dog to a control post, quarantine, re-expedition, seizure or another measure.

The consequences can be serious. Under Article L. 236-9 of the Code rural et de la pêche maritime, when animals do not meet the applicable conditions, the authorities may prescribe “la mise en quarantaine des animaux, leur abattage, la consigne des produits, la destruction ou la réexpédition des animaux”. In English, the statutory list includes quarantine, slaughter, destruction and re-expedition. The provision is a toolbox for animal-health enforcement; it does not mean that every minor paperwork error leads automatically to euthanasia. It does mean that an owner should not ignore a written direction or leave the dog in an uncontrolled situation while arguing with a carrier.

The current French customs information gives a particularly important warning for movements that fall outside the private route. If one of the conditions for a companion-animal movement is not met, the animals may have to be presented at a border control post with a commercial-import health certificate. Not every border control post is authorised to inspect every species. If the entry point is not designated for the relevant animal, the veterinary services may systematically order re-expedition. This is why the choice of route and point of entry must be checked before departure, not improvised after the vehicle has arrived.

The most common documentary problems can be grouped as follows:

Problem identified	Immediate proof to collect	Action to request
Chip not readable or number differs	Fresh scan, chip certificate, complete vaccination record and any reader report	Ask whether the defect can be corrected at the entry point or whether a written re-expedition decision has been made.
Rabies date, booster or validity challenged	Original vaccination history, manufacturer data, date of chip and vet statement	Ask the officer to identify the exact date or validity requirement applied.
Certificate rejected	All pages of the original certificate, official-vet status, issue date and entry date	Request the missing signature, model or endorsement to be identified in writing.
Private route questioned	Owner booking, authorisation, number of animals, no-sale statement and relocation evidence	Ask whether a commercial certificate or designated border control post is required.
Dog too young or prohibited type	Date of birth, breed or pedigree evidence, photographs and veterinary records	Do not attempt concealment; obtain the legal decision and urgent advice before moving the dog.

Evidence from the courts shows why a bare passport is not always decisive. In CAA Douai, 24 May 2022, no. 21DA01207, the dispute concerned the re-expedition of puppies regarded as not validly vaccinated against rabies. The court examined the age assessment, the vaccination timing, the passports and the veterinary material. The judgment records that the importer “n’apporte aucun élément sérieux de nature à remettre en cause les conclusions du vétérinaire mandaté par les services de l’Etat”. The case concerned a professional operation from Hungary, not a private British owner, but it illustrates the practical point: the owner must attack the specific veterinary finding with reliable evidence rather than rely on the document’s cover alone.

Similarly, Cour de cassation, criminal chamber, 3 December 2019, appeal no. 18-85.401 concerned non-compliant puppy imports and criminal findings in a commercial context. It is not a basis for assuming that an ordinary traveller has committed a criminal offence because a carrier has asked a question. It is a warning about the risk created by falsified dates, unreliable health documents, professional import activity and actual non-compliance. Never alter a vaccination entry, ask a person to backdate a certificate, or describe a change of ownership as a private holiday journey.

There is a separate statutory criminal layer. Article L. 237-3 of the Code rural et de la pêche maritime provides serious penalties for introducing animals that do not meet the health or animal-protection conditions referred to in Article L. 236-1, particularly where the conduct and the health consequences satisfy the criminal provision. The existence of the article does not remove the need to prove the relevant facts, the applicable route and the person’s conduct. It does mean that deliberate document fraud or a knowingly non-compliant commercial import should never be treated as a harmless administrative shortcut.

If the issue is a dog classified as a category 1 attack dog, the problem is not a missing certificate that can be cured at the ferry desk. France’s customs guidance states that category 1 dogs are prohibited from importation, while category 2 guard and defence dogs are subject to specific rules. The relevant French dangerous-dog restrictions include the persons who may not keep such a dog. Article L. 211-13 of the Code rural et de la pêche maritime is one of the provisions to check alongside the current customs guidance. Gather pedigree or classification evidence before travel; a breed description used informally in Britain may not match the French legal category.

If the dog is detained, arrange safe care and veterinary observation at once. Ask where the dog is being kept, who is responsible for food and medication, which expenses are accruing, whether the owner may attend, and the precise condition for release or re-expedition. Preserve receipts and photographs. These steps do not replace the legal challenge, but they protect the dog and create evidence about urgency, welfare and the proportionality of the chosen measure.

B. Can I challenge a re-expedition, quarantine or euthanasia measure?

A written measure by a French public authority is normally challenged through administrative law, with the exact court and procedure depending on the authority, the place, the decision and the time left before execution. Do not assume that an email to a ferry operator suspends a French decision. Do not assume that a complaint to a ministry pauses re-expedition. Read the operative part, identify the issuing authority, calculate the deadline, and ask for an immediate stay or urgent order where the facts justify it.

For an ordinary suspension request, Articles L. 521-1 and L. 521-2 of the Code de justice administrative provide the main urgent frameworks to examine. Article L. 521-1 concerns suspension where urgency exists and a serious doubt about legality is raised. Article L. 521-2 is the référé-liberté procedure: in an urgent case, the judge may order measures necessary to safeguard a fundamental freedom where a public body or public-service body has caused a serious and manifestly unlawful interference. The text says that the judge “se prononce dans un délai de quarante-huit heures”. The deadline is not a promise that every application succeeds; it is a reason to prepare and file a coherent application immediately when execution is imminent.

The first legal question is whether the order is properly based on the facts. A document refusal caused by an unreadable chip is different from an order based on a suspected rabies exposure. A commercial-route failure is different from an allegation that the owner falsified a vaccination record. A carrier’s internal checklist is different from a decision signed by customs, a veterinary service or a prefect. The application should identify the error, the document that proves it, the authority that made it, and the concrete harm that will occur before the ordinary proceedings can be heard.

The second question is proportionality. The older but still relevant Conseil d’État decision of 11 July 2014, no. 359394 dealt with dogs potentially exposed to rabies. The Court accepted that a prefect can act against a serious health risk, but it found that killing the dogs was not proportionate where surveillance could protect public health. The official decision states that “La décision de les faire abattre n’était pas proportionnée, dès lors qu’il était possible de les maintenir sous surveillance sans risque avéré pour la santé publique.” This case does not create a right to enter France without the required documents. It shows that an authority must connect the measure to the evidence and consider a less severe measure where the statutory conditions permit it.

The same proportionality logic appears in CAA Bordeaux, 13 March 2012, no. 10BX01401, where the court annulled euthanasia measures concerning dogs that had not been shown to present the relevant level of danger. Again, the facts concerned suspected rabies and municipal measures, not a routine Brexit document problem. The case belongs in an urgent file because it gives a precise judicial reference for challenging a response that goes beyond what the verified health risk requires. It cannot be used to argue that a missing animal health certificate is irrelevant.

A recent urgent decision also confirms the importance of the factual record. In Conseil d’État, urgent applications judge, 1 April 2026, no. 514121, the proceedings concerned a municipal order relating to a dangerous dog and the statutory notion of “danger grave et immédiat”. The case is not about UK entry documents. Its value for a border file is narrower: where an authority invokes an urgent danger, the owner should demand the precise facts, veterinary findings and statutory basis rather than allow a verbal category to stand in for an actual decision.

The rabies provisions must be kept separate from paperwork. Article L. 223-9 of the Code rural et de la pêche maritime begins with the rule: “La rage, lorsqu’elle est constatée chez les animaux de quelque espèce qu’ils soient, entraîne l’abattage, qui ne peut être différé sous aucun prétexte.” That text concerns rabies when it is established. A dog whose certificate is incomplete is not thereby proven to be rabid. Conversely, an owner facing a genuine suspected-exposure measure must not trivialise the public-health risk. The urgent application should distinguish identity non-compliance, vaccination non-compliance, suspected exposure and confirmed disease.

The evidence bundle should be chronological and indexed. Include the dog’s date of birth; microchip implantation and scan reports; every rabies entry; the vaccine product and manufacturer information; the signed animal health certificate; proof of official-veterinarian status; the owner’s travel booking; the written authorisation if relevant; the no-sale explanation; photographs of the dog and chip record; the carrier’s refusal; the customs or veterinary decision; the dog’s medical and welfare evidence; and a short statement of the remedy requested. If the issue is translation, provide the original document and a faithful translation without replacing the original.

Ask for a precise order. The desired outcome might be release, permission to continue to France, a new documentary check after a chip scan, a temporary supervised stay, suspension of re-expedition, or substitution of surveillance for destruction. Courts respond better to an operational request tied to evidence than to a general complaint that Brexit is unfair. If a certificate genuinely cannot be corrected at the border, the safer request may be a controlled and documented return to Great Britain, followed by a compliant journey, while preserving a claim about unreasonable costs or an unlawful decision.

There may also be a private claim against a carrier, seller, transporter, broker or veterinary professional. Preserve the booking terms, messages, instructions, payment records, refusal reason and additional kennel or travel costs. A private damages claim does not normally suspend a public-law border measure. Deal with the urgent public decision first, then assess contractual or professional liability. If a seller supplied an inaccurate passport or a carrier gave a contradictory instruction, that evidence may become important after the dog is safe.

Do not publish or circulate a false statement that the dog has been “cleared” merely because one person at a check-in desk did not inspect it. The legal status is established by the controlling documents and the competent authority. Likewise, do not destroy the original certificate, surrender a passport without a receipt, or let a third party take ownership in order to make the journey appear non-commercial. Those actions can make both the animal-health and evidence problems worse.

Finally, remember the limits of the case law. The 2021 Cour de cassation decision and the 2019 Cour de cassation decision arose from commercial puppy-import prosecutions. The 2022 CAA Douai decision involved a professional re-expedition order. The Conseil d’État rabies decisions involved public-health exposure. They help define proof, reasoning and proportionality; they do not erase the current 2026 entry rules. The legal task in a private British relocation is to place the correct facts in the correct category and to challenge only the measure that is actually wrong.

Conclusion

A British owner can generally move a dog from Great Britain to France after Brexit, but the journey must be planned as a third-country entry into the European Union. The practical sequence is: classify the movement as genuinely non-commercial; verify the departure territory; check the microchip before the rabies vaccination; respect the vaccination and age rules; obtain the original animal health certificate from an official veterinarian within the ten-day entry window; use the correct document rather than an invalid Great Britain-issued passport; present the dog and papers at the travellers’ point of entry; and plan the separate tapeworm requirement for the return to Great Britain.

If the dog is refused, obtain a written reason and the operative decision. Identify whether the problem is boarding, documentary verification, commercial classification, the designated control post, re-expedition, quarantine or a health-risk order. Then assemble the evidence and act through the appropriate administrative route. Articles L. 236-1, L. 236-4 and L. 236-9 of the French Rural and Maritime Fishing Code provide the national control framework; the 2026 EU regulations provide the current non-commercial movement and document rules; and the verified court decisions show that documentary proof, reasoning and proportionality matter. A missing page may be curable. A false entry, an ownership transfer or a prohibited category may require a different route entirely.

For a broader overview of the first legal year after relocation, see the moving to France from the UK after Brexit legal checklist. Keep the current French customs page, the current GOV.UK travel guidance and the original veterinary records together, and recheck them before every crossing because the certificate window, vaccination status and route-specific conditions can change.
