Moving abroad with a pet
An international pet move starts months before departure: microchip, vaccines, antibody test, import permit. The list adapts to how your pet is flying.

[ ] Start 4–6 months ahead, not weeks
    The antibody test and mandatory waiting period after it can take months. Starting late can mean it simply won't be ready by your flight date.
[ ] Check destination requirements on an official source
    Pet import rules vary hugely and change often — check the embassy or the destination's veterinary authority site, not a forum post from a few years back.
[ ] Confirm the microchip is ISO-compliant
    You need a 15-digit ISO 11784/11785 chip. Many countries require the chip to be implanted BEFORE the rabies vaccination, or the vaccine has to be redone after the chip.
[ ] Match the rabies vaccine timing to the rules
    You'll typically need the vaccine given a set number of days after chipping, and within a set window before travel — get the exact dates for your destination.
[ ] Get an antibody (titer) test if required
    Several destinations (EU countries, UK, Australia, Japan) require a FAVN blood test at an approved lab, plus a waiting period after the result — this is the longest step, plan backward from it.
[ ] Get the international health certificate
    Issued by an accredited vet within a narrow window before departure (often 10 days) and may need government endorsement — confirm the exact validity for your route.
[ ] Apply for an import permit ahead of time
    Some countries require a pre-approved import permit, not just paperwork at the border — find out if yours does before booking flights.
[ ] Book the pet spot directly with the airline
    Pet quotas per flight are limited and booked separately from your ticket. Ask about seasonal or breed restrictions (brachycephalic breeds, summer heat embargoes).
[ ] Check quarantine requirements at the destination
    Some countries need only paperwork, others require mandatory on-arrival quarantine — budget the time and cost in advance, not after you land.
[ ] Buy an IATA-compliant crate
    Your pet must be able to stand, turn around and lie down inside. It needs a leak-proof tray, food/water dishes attached to the door, and a 'Live Animal' label.
[ ] Crate-train weeks before the flight
    Feed inside it with the door open, starting weeks ahead — an unfamiliar crate on travel day massively raises the stress level.
[ ] Get an acclimatization certificate for extreme weather
    If extreme heat or cold is expected on the route, cargo transport may need a separate vet-issued acclimatization certificate.
[ ] Confirm the layover airport allows pet transit
    Not every hub allows cargo pet transit — a cheap connecting flight can otherwise mean your pet gets stuck at a transfer airport.
[ ] Check the carrier size limits for that specific airline
    Under-seat size limits differ by airline, not by alliance — check the exact carrier you're flying with, not a general rule of thumb.
[ ] Don't sedate without a vet's guidance
    IATA advises against sedation before flying — it can dangerously affect breathing and temperature regulation at altitude. Talk to your vet about alternatives for an anxious pet.
[ ] Update the microchip registry to the new address
    Do this right after arrival — a lost pet with a chip pointing to your old address and phone number is much harder to reunite with you.
[ ] Line up a vet and check food availability at the destination
    If the usual food brand isn't sold there, start a gradual switch to an alternative before you leave — a sudden food change on top of travel stress is rough.
[ ] Pack a familiar blanket or toy
    A familiar scent inside the crate calms a pet more than anything new bought just for the trip.
[ ] Bring cash for border inspection fees
    The document and animal inspection on arrival is often a paid, cash-on-the-spot fee — check the amount ahead of time.
[ ] Keep pet documents in their own folder
    Pet passport, health certificate, import permit — kept apart from your own documents, ready to hand over at check-in and at the border.
