Since 1 January 2021, your dog has crossed the Channel as a third-country animal. The European Union pet passport issued in Great Britain no longer opens the French border on its own, every trip from Britain now needs its own animal health certificate, and once you settle in France your dog must carry French identification and sit on the national I-CAD register. Get any of this wrong and the consequences are immediate: a refused boarding at Folkestone or Dover, a fine from the police municipale, a bill from the fourrière, the municipal kennel, or, in the worst cases, a mayoral order placing your dog in a pound and authorising euthanasia. This guide explains the whole chain in plain English, with every French term translated at first use. The first part covers the journey and the paperwork: the microchip, the rabies wait, the ten-day animal health certificate, the tapeworm treatment for the return, and the seven-day I-CAD registration once your stay exceeds three months. The second part covers the hard edge of French dog law: category dogs, the mayor’s ownership permit, muzzles and insurance, what happens within hours of a bite, who pays under the strict liability of article 1243 of the Civil Code, and how to challenge a fine, a refusal, a compensation claim or a seizure order with the right evidence and the right deadlines.

I. Bringing Your Dog from Britain and Keeping Its Papers in Order in France: the Animal Health Certificate, the Microchip and I-CAD Registration

A. How to bring your dog from Great Britain to France after Brexit: microchip, rabies wait and the ten-day animal health certificate

Start with the uncomfortable Brexit truth: for pet travel, Great Britain is now a third country listed for the non-commercial movement of pets under Regulation (EU) No 576/2013 of the European Parliament and of the Council, and the old route of travelling on a British-issued European Union pet passport is finished. The British government guidance on taking your pet dog, cat or ferret abroad states the current position plainly: before entering the European Union you must obtain an animal health certificate from your veterinary surgeon, and you need a new one for every single journey from Great Britain to the European Union. One certificate per trip, no exceptions, no annual document that covers the year. The same official page confirms the two features that make the certificate awkward for spontaneous travel. After the date of issue, your pet’s animal health certificate is valid for ten days for entry into the European Union, with day one being the date the certificate is issued, and you may then use that same certificate for onward travel between European Union countries during the same trip, for up to six months after entering the European Union. Miss the ten-day window because the ferry was cancelled or the lorry broke down, and you start again with a fresh paid appointment.

Behind the certificate sit two older conditions that have not changed but now trap British owners who rush. First, the microchip. The guidance requires you to have your dog microchipped before, or at the same time as, its rabies vaccination, and warns that if you do not, the animal will need to be vaccinated again. A tattoo is only accepted in narrow historical cases, so for a British dog in practice it is chip first, needle second, and the chip number must appear on every later document. Second, the rabies vaccination itself. Your veterinary surgeon needs proof that your puppy is at least twelve weeks old before vaccinating, and how long you must wait before travelling depends on the vaccine used, with a minimum of twenty-one full days after the first vaccination or the last injection of the first course. A booster given on time inside the validity of the previous vaccination does not restart the clock, but a lapsed booster does, which is how families who vaccinated religiously for years suddenly find themselves counting twenty-one days in a Dover hotel car park. Check the dates on the certificate against the vaccination record before you leave the surgery, because a one-day error invalidates the whole document at the border.

Dogs need one more treatment that cats and ferrets escape: worms. A veterinary surgeon must treat your dog against the Echinococcus multilocularis tapeworm and record the treatment in the travel document for listed destinations, and you must also arrange a tapeworm treatment for the return journey to Great Britain from most countries, France included. The treatment must contain praziquantel or an equivalent proven effective against that tapeworm, it must be administered by a veterinary surgeon, and it must fall inside a strict window before your scheduled arrival. The official guidance illustrates the window with a simple example: a dog treated at 1pm on Monday must arrive after 1pm on Tuesday and cannot arrive after 1pm on Saturday. In practice this means booking a French veterinary surgeon two to four days before your return ferry or tunnel, carrying the stamped document, and keeping the appointment slip. Owners who leave the treatment to the morning of travel or who let an unqualified person administer the tablet discover at Calais that the dog cannot board.

Two practical warnings complete the journey. First, the certificate habit. Because each trip needs its own certificate, second-home owners who shuttle five or six times a year now pay for five or six certificates, and each one demands the same checks. Build a file that travels with the dog: the current animal health certificate, the vaccination history showing the unbroken chain, the microchip number, and the tapeworm record. Second, the forbidden shortcut. French criminal law punishes the import or introduction onto metropolitan territory of a first-category attack dog with six months’ imprisonment and a 15,000 euro fine, in the words of article L215-2 of the Rural and Maritime Fishing Code: It punishes anyone who imports or introduces a first-category dog onto metropolitan territory, and it adds: “Le fait de détenir un chien de la première catégorie sans avoir fait procéder à sa stérilisation est puni des mêmes peines.” If your dog looks like a pit bull type, read the second part of this guide before you even book, because some dogs that are perfectly legal in Britain cannot lawfully enter France at all.

B. Once you live in France: French identification, the seven-day I-CAD registration and the certificate before adopting or buying

The day you move from visitor to resident, French domestic law takes over from travel law, and its first demand is identification. Article L212-10 of the Rural and Maritime Fishing Code provides: “Les chiens, les chats et les furets, préalablement à leur cession, à titre gratuit ou onéreux, sont identifiés par un procédé agréé par le ministre chargé de l’agriculture mis en œuvre par les personnes qu’il habilite à cet effet. Il en est de même, en dehors de toute cession, pour les chiens âgés de plus de quatre mois, pour les furets âgés de plus de sept mois nés après le 1er novembre 2021 et pour les chats de plus de sept mois. L’identification est à la charge du cédant.” In ordinary language: every dog over four months old living in France must be identified by microchip or, for older animals, tattoo, by an authorised person, normally a veterinary surgeon. Your British microchip satisfies the technical requirement, but the French system must be able to read it back to you, which is where the national register comes in.

That register is the Fichier National d’Identification des Carnivores Domestiques, run by the body called I-CAD, and registration is not optional for settlers. The I-CAD official questions page states the rule by reference to article 22 of the order of 1 August 2012: where the stay in France exceeds three months, the keeper must apply to register the animal in the I-CAD national file within seven days of arrival on French soil. The keeper, meaning you as owner or holder, must apply for registration within seven days of arrival on French soil where the stay exceeds three months. The same page explains the channel: to have your animal’s identification recorded in the French national file, see a veterinary surgeon of your choice practising on French territory, who draws up the provisional identification certificate used for imports and intra-Community exchanges, supported by the original health certificate from the country of origin. Book that veterinary appointment in your first week. Owners who wait six months and then lose the dog discover that the British chip number alone does not bring the animal home, because the French pound, the fourrière, searches the French file first.

Keep the registration alive afterwards, because the file is only as good as its last update. Moves within France, changes of telephone number, a sale or gift of the dog, and the death of the animal should all be notified, through your veterinary surgeon or your holder account on the I-CAD holder area. If your dog is picked up straying, article L211-25 of the Rural and Maritime Fishing Code requires the pound keeper to look for the owner without delay where the animal is identified, but the second half of that article is brutal: “A l’issue d’un délai franc de garde de huit jours ouvrés, si l’animal n’a pas été réclamé par son propriétaire, il est considéré comme abandonné et devient la propriété du gestionnaire de la fourrière”, meaning that after a clear period of eight working days unclaimed, the animal is deemed abandoned and becomes the property of the pound keeper. Eight working days pass quickly when you are back in Britain and the mairie writes only in French. Give a French neighbour or your veterinary surgeon a copy of the identification card and a mandate to act, and check the national lost-and-found application Filalapat at once if the dog vanishes.

If instead of importing you acquire a dog in France, by purchase or adoption, a consumer-protection layer now sits on top of identification. The English-language service-public guide to owning a dog or cat explains that the seller must have you sign a certificate of commitment and knowledge, and that this certificate is valid only seven days after its issue date, giving you a cooling-off period to absorb the information it contains; the seller must verify that the certificate was issued to you at least seven days earlier. The same guide lists what the seller must hand over: a veterinary certificate less than three months old drawn up after examination of the animal, and the document proving the animal’s identification in the I-CAD national file. Never accept a puppy without papers against a promise that registration will follow, and never pay a deposit that pressures you to sign the commitment certificate and collect the animal on the same day. A seller who skips the seven days or the veterinary certificate is already signalling how disputes will go, and your first letter of formal notice, the mise en demeure sent by recorded delivery, will quote exactly these missing documents.

II. Category Dogs, Bites and Disputes: Permits, Strict Liability and How to Challenge a Fine, a Bill or a Seizure Order

A. If your dog is, or is said to be, dangerous: categories, the mayor’s permit, insurance, muzzles and criminal penalties

France sorts supposedly dangerous dogs into two statutory categories, and the classification decides almost everything that follows. Article L211-12 of the Rural and Maritime Fishing Code lists the types concerned and then provides: “sont répartis en deux catégories : 1° Première catégorie : les chiens d’attaque ; 2° Deuxième catégorie : les chiens de garde et de défense.” First category means attack dogs, essentially pit bull types without pedigree papers, Boerboels and Tosas; second category means guard and defence dogs, including pedigreed American Staffordshire terriers, Rottweilers, Tosas with papers and similar types fixed by ministerial order. Only a veterinary surgeon is competent to determine the racial type of an animal, and the service-public page on category dogs recommends obtaining a veterinary attestation where there is doubt, to show to the police or gendarmerie at a check. For a British owner this is the single most useful piece of paper after the identification card: if your Staffordshire bull terrier, a breed that is not categorised, is mistaken for a pit bull type at a roadside check, the veterinary attestation ends the discussion on the spot.

Owning a categorised dog in France is a licensed activity, and the licence comes from the mayor of your commune of residence, the mairie. Article L211-14 of the Rural and Maritime Fishing Code states the principle: “la détention des chiens mentionnés à l’article L. 211-12 est subordonnée à la délivrance d’un permis de détention par le maire de la commune où le propriétaire ou le détenteur de l’animal réside”, meaning keeping such dogs requires an ownership permit issued by the mayor, and the permit must be shown at the town hall of each new commune when you move. The file is heavy by design: proof of identification, valid rabies vaccination, third-party liability insurance covering damage the dog may cause to others, with family members counted as third parties, proof of sterilisation for first-category males and females, the holder’s suitability certificate, and the dog’s behavioural assessment, with a provisional permit where the puppy is too young for assessment. The suitability certificate, the attestation d’aptitude, follows a day’s training on behaviour, prevention and everyday management; it attaches to the person, not the dog, so a buyer must hold their own. Civil liability insurance is compulsory, and service-public warns that going without exposes you to a fine of up to 450 euros. Start the file before the dog arrives, because the behavioural assessment, the évaluation comportementale, must be carried out by an approved veterinary surgeon on a departmental list, and waiting lists in August in the Dordogne are real.

Daily life with a categorised dog is then governed by muzzles, leads and bans. Article L211-16 of the Rural and Maritime Fishing Code is direct: “Sur la voie publique, dans les parties communes des immeubles collectifs, les chiens de la première et de la deuxième catégorie doivent être muselés et tenus en laisse par une personne majeure.” On the public highway and in the shared areas of blocks of flats, first- and second-category dogs must be muzzled and kept on the lead by an adult, with the same duties extended to second-category dogs in public places, premises open to the public and public transport. First-category dogs go further into prohibition: no access to public transport, to public places except the highway itself, or to premises open to the public, and no waiting in the shared areas of blocks. Your thirteen-year-old cannot lawfully walk the Rottweiler to the boulangerie, however sensible the child, and the neighbour who photographs the unmuzzled animal in the lift has just created Exhibit 1. Note also that a landlord or a co-owner may seize the mayor where a dog living in one of their flats seems dangerous, and the mayor may then deploy the full dangerous-animal procedure described below. If you rent, tell the agency and the syndic, the managing agent of the co-ownership, that the file is in order before someone else tells them it is not.

The criminal stakes explain why mayors and prosecutors take these files seriously. Detaining a first-category dog without sterilisation draws the same penalties as importing one, as quoted in the first part of this guide. Convicted owners additionally face confiscation of the dogs, a ban of up to five years on any professional or social activity whose facilities were knowingly used for the offence, and a ban of up to five years on keeping first- or second-category dogs. Below the criminal level, simply letting a potentially dangerous animal stray is a second-class petty offence under article R622-2 of the Criminal Code: “Le fait, par le gardien d’un animal susceptible de présenter un danger pour les personnes, de laisser divaguer cet animal est puni de l’amende prévue pour les contraventions de la 2e classe.” The court may then hand the animal to a recognised animal-protection charity. If the mairie refuses your permit, do not walk the dog while you argue. File a written reconsideration request with the mayor, the recours gracieux, attaching the missing or corrected document, and if the refusal stands, take the refusal letter to a lawyer quickly for an appeal to the administrative court, the tribunal administratif, because time limits there are short and counted in weeks, not months.

B. When your dog bites, injures or is seized: declarations, vet surveillance, who pays and how to fight back

A bite sets off two parallel machines within hours: a health machine and a dangerousness machine. The health machine is rabies surveillance. Article L223-10 of the Rural and Maritime Fishing Code provides: “Tout animal ayant mordu ou griffé une personne, même s’il n’est pas suspect de rage, est, si l’on peut s’en saisir sans l’abattre, soumis par son propriétaire ou détenteur et à ses frais à la surveillance du vétérinaire sanitaire.” Every animal that has bitten or scratched a person, even with no suspicion of rabies, must be placed by its owner or keeper, at their expense, under the supervision of the official veterinary surgeon, and the police authority reminds the owner of these duties and serves a formal demand to comply within twenty-four hours where needed. In practice this means three veterinary visits over fifteen days, paid by you, with the veterinary surgeon reporting any sign of rabies. Skipping the visits is itself an offence and it poisons everything that follows, because the mayor reads non-compliance as dangerousness.

The dangerousness machine starts with a declaration you must make yourself. Article L211-14-2 of the Rural and Maritime Fishing Code provides: “Tout fait de morsure d’une personne par un chien est déclaré par son propriétaire ou son détenteur ou par tout professionnel en ayant connaissance dans l’exercice de ses fonctions à la mairie de la commune de résidence du propriétaire ou du détenteur de l’animal.” Every bite of a person must be declared by the owner, the keeper or any professional who learns of it in the course of duty, to the town hall of the owner’s or keeper’s commune. The owner or keeper must then submit the dog to the behavioural assessment, which is sent to the mayor, and after that assessment the mayor or, failing that, the préfet, the state’s representative in the département, may order the owner or keeper to train and obtain the suitability certificate. Refusal authorises the mayor to order the animal placed in a suitable pound by order, and in cases of serious and immediate danger, after advice from a veterinary surgeon appointed by the préfet, to have it euthanised. Declare first, volunteer the assessment, and keep every receipt, because the file you build in week one is the file the mayor reads in week three.

Behind those bite rules sits the general dangerous-animal power that applies to every dog, categorised or not. Article L211-11 of the Rural and Maritime Fishing Code provides: “Si un animal est susceptible, compte tenu des modalités de sa garde, de présenter un danger pour les personnes ou les animaux domestiques, le maire ou, à défaut, le préfet peut prescrire à son propriétaire ou à son détenteur de prendre des mesures de nature à prévenir le danger.” Where an animal, given how it is kept, may present a danger, the mayor or the préfet may order the owner or keeper to take preventive measures, potentially after a behavioural assessment, including training and the suitability certificate. Non-compliance allows the mayor to place the animal in a suitable pound by order, and if, after a clear period of eight working days in the pound, the owner offers no guarantee of compliance, the mayor authorises the pound keeper, after advice from the prefectoral veterinary surgeon, to have the animal euthanised or rehomed. The safeguard that saves owners is procedural and stated in the same article: “Le propriétaire ou le détenteur de l’animal est invité à présenter ses observations avant la mise en oeuvre des dispositions du deuxième alinéa du présent I”, the owner or keeper is invited to submit observations before impoundment. Answer that invitation in writing, within the stated time, with the behavioural counter-assessment, training enrolment, muzzle and insurance proofs attached. Silence at that stage is routinely quoted back in the euthanasia order.

Then comes money: who pays the victim. French law answers with one of the harshest rules in Europe. Article 1243 of the Civil Code provides: “Le propriétaire d’un animal, ou celui qui s’en sert, pendant qu’il est à son usage, est responsable du dommage que l’animal a causé, soit que l’animal fût sous sa garde, soit qu’il fût égaré ou échappé.” The owner, or whoever uses the animal while it is entrusted to them, is liable for the damage the animal caused, whether it was in their keeping or had strayed or escaped. The tribunal judiciaire of Aix-en-Provence, in its judgment of 5 June 2025, RG 22/05565, a case about a bitten left hand claimed against the dog’s owner, restates the rule without mercy: the keeper faces automatic liability, with no need to prove fault and no escape by proving blamelessness. Liability is automatic; proving your fault is unnecessary and proving your innocence is useless. The victim need not show poor training or poor supervision, and only force majeure, the act of a stranger or the victim’s own fault can exonerate, in whole or in part. The court found all conditions met from the medical certificate, the pedigree naming the owner and uncontested facts: on uncontested medical and pedigree evidence, all the conditions for animal liability were met and the defendant answered as owner for the bite wound.

The decisive practical question is usually not whether someone pays, but who exactly the keeper was at the fateful second. The tribunal judiciaire of Grenoble, in its judgment of 2 April 2026, RG 24/03894, about a child bitten in a park by a Malinois-type dog being walked by a thirteen-year-old, holds that transfer of keeping is assessed on the concrete facts of each case. The owner had left the dog with his brother, who let his young son walk it, so the owner had neither use, control nor direction, however brief the transfer, and the court concluded that the brother, holding powers of control, use and direction over the dog at the time, had keeping of it. He therefore bore full liability while the owner’s own insurer was put out of the case. For British families this holding matters twice over: the neighbour who walks your dog, the visiting teenager who holds the lead, the professional dog-sitter all potentially move liability, and the corresponding insurer, onto themselves. Put every regular arrangement in a dated writing, check that the walker’s own liability cover extends to animals in their keeping, and never hand a powerful dog to a child, a point the Grenoble court underlined by criticising the negligence of letting a thirteen-year-old walk a Malinois in a children’s park.

Proof decides these cases, and the Paris Court of Appeal shows what persuades. In its judgment of 14 September 2023, RG 20/12116, an attack by an American Staffordshire terrier on a papillon spaniel in the shared areas of a residence, the court recalls that each party must prove the facts needed for its claim, then sets out article 1243 of the Civil Code in full before weighing the evidence. What carried weight on the facts were contemporaneous documents: a medical certificate three days after the events noting scratches and shock, photographs corroborating the wounds, and above all same-day and later veterinary certificates describing bite-compatible wounds, fang impacts, skin tearing and surgery. Mirror that discipline from minute one. Photograph all wounds and torn clothing with a date stamp, get a medical certificate within days, have your veterinary surgeon record every lesion the same day, keep every invoice, and identify witnesses with full details while memories are fresh. The French health fund, the CPAM, will in any event pursue the liable keeper for its outlay, as it did in the Aix case, so expect a second front even where the victim stays quiet.

How, then, do you fight back at each stage. Against a compensation demand, answer on keeping and causation, not on love for the animal: show who truly held control, use and direction, raise the victim’s provocation where the file supports it, and route everything through your liability insurer within the policy’s declaration deadline, commonly five working days. If your insurer refuses cover by arguing that custody had passed, the Grenoble reasoning is your template or your warning depending on which side you sit. Against a mayoral measure, use the observations invitation, commission an independent behavioural assessment from another listed veterinary surgeon, enrol in training at once, and insure, muzzle and secure the property before the eight-day pound clock runs. Against a fine for straying or missing papers, check the notice for the facts, time, place and animal identification, and contest inaccuracy in writing within the stated deadline rather than paying under protest and complaining later. And where the town hall, the préfet or an insurer will not move, the administrative court reviews mayoral orders and the civil courts fix compensation, with legal aid, the aide juridictionnelle, available for residents of modest means. At every stage the same three exhibits win: the identification card, the insurance certificate and the dated veterinary paper.

Conclusion

A dog in France after Brexit lives under two flags. Under the travel flag, the animal health certificate rules each crossing: chip before rabies, twenty-one days after the first vaccination, a new certificate for every trip valid ten days for entry, and a veterinary tapeworm treatment inside the strict window for the return to Britain. Under the residence flag, French law takes the lead within days: identification for every dog over four months, registration in the I-CAD national file within seven days of arrival where the stay exceeds three months, a suitability process and a mayoral permit for category dogs, muzzles and adult handling in shared spaces, and automatic liability for whoever keeps the animal when damage occurs. The bite procedure compresses all of this into days: declaration to the mairie, official veterinary surveillance at your expense, a behavioural assessment on the mayor’s desk, and an invitation to submit observations that you must never ignore. Keep four documents within arm’s reach at all times: the travel certificate, the French identification card, the insurance certificate and the veterinary file. With those, most checks end in minutes and most claims settle; without them, a beloved pet becomes an administrative file, and administrative files in France move faster than appeals.
