the dog's coming. here's the paperwork.
to take your dog from the uk into the eu you need three things — a registered microchip, a valid rabies vaccination, and a single-use animal health certificate. then one vet visit before you come home. none of it is hard, but the timings are strict.
three things, in this order.
a registered microchip.
your dog must be microchipped before, or on the same day as, their rabies vaccination. chip after the jab and the jab has to be done again.
a valid rabies vaccination.
dogs must be at least 12 weeks old to have it, and you must wait 21 full days after the first vaccination before travelling. boosters don't need the wait as long as the cover hasn't lapsed.
an animal health certificate.
the ahc replaces the pet passport for gb residents. an official veterinarian issues it within 10 days of your arrival in france; it's single-entry, and good for 6 months of travel within the eu. the gov.uk pet travel guide has the official detail.
