Question 1

How far in advance does the rabies vaccine need to be given?

Accepted Answer

Every country reads the rabies vaccine on its own clock. In the United States a first-time (primary) vaccine is not considered valid for international travel until 28 days after the dose, per USDA APHIS guidance; boosters given before the previous vaccine lapses are valid immediately. The United Kingdom PETS scheme requires the rabies vaccine to be at least 21 days old before entry, with the booster cycle intact. Australia applies the strictest rule of the five live routes — a 180-day post-vaccine waiting window plus a passing FAVN titer — referencing the Department of Agriculture, Fisheries and Forestry (DAFF) BICON entry conditions. Plan the vaccine first, then count backwards from the travel date so the window is already open on arrival.

Question 2

What is a rabies titer (FAVN) and when does its lab window open?

Accepted Answer

The FAVN (Fluorescent Antibody Virus Neutralization) test is the lab proof that a rabies vaccine has actually taken. A vet draws serum and ships it to an approved lab — Kansas State University (KSU) is the reference lab for US-origin pets, and Labsed-CONICET in Buenos Aires is the contracted lab for Brazil-origin moves. Turnaround is typically two to four weeks. Australia and Hawaii accept a FAVN result dated at least 180 days before arrival but consider it expired after the animal’s annual booster cycle lapses. On a São Paulo → Sydney move the titer is the single longest lead-time item in the plan; book the draw before booking the flight.

Question 3

When should the ISO 15-digit microchip be implanted relative to the first rabies vaccine?

Accepted Answer

The microchip must be implanted before the very first rabies vaccine is given — otherwise border control cannot link the animal’s identity to the vaccine record, and the entire chain is treated as if no vaccine exists. A vet must scan the chip and confirm the 15-digit ISO 11784/11785 number before drawing the dose, and re-scanning it at every subsequent checkpoint is standard practice. If your pet was chipped with a 9- or 10-digit non-ISO chip (common in older US rescues), bring it in for a re-chip before the first vaccine; the new chip’s number is what every downstream document records.

Question 4

How does the IATA container sizing rule actually work?

Accepted Answer

IATA LAR Container Requirement 1 calculates the interior dimensions of the kennel from the animal itself. Length equals the pet’s body length (snout to base of tail) plus half its height at the shoulder; width equals the body length; height equals the pet standing head-up. The result lands in one of the Series 200 (very small), 300 (small cats), 400 (medium cats and small dogs), 500 (medium dogs), or 700 (Series 700 only for animals too large for 500, with two-part construction, metal-reinforced doors, and mandatory ventilation on all four sides) ranges. Pets over roughly 40 lb need a two-part kennel with screws (not clips), removable wheels so the pet cannot be rolled, and a clip-on water bowl accessible from outside the crate. Pet Atlas returns a crate spec on every paid plan — model, exact dimensions, accessory list — so the kennel you buy fits the animal and the airline.

Question 5

Which routes deny snub-nose breeds outright, which only embargo them seasonally, and which airlines have their own list on top of the country rule?

Accepted Answer

The United Kingdom has no country-level snub-nose ban — entry is gated on documentation, not breed — but British Airways cargo has historically embargoed brachycephalic cats and dogs outside temperate months. France and Germany impose no country-level snub-nose ban; whether the animal flies is decided by the carrier (Lufthansa’s FlyAccept PET embargo matrix is the public reference on the EU side). Australia embargoes brachycephalic breeds on Qantas cargo between November and March (Boston Terrier, Pug, French Bulldog, Persian cat) — heat-stress risk is the reason. Many US carriers (United, American, Delta cargo) deny snub-nose pets outright year-round, regardless of the destination’s country rule. Plan checks all three layers — country, airline, season — before booking.

Question 6

Can a pet travel through a connecting (transfer) airport, and what is involved?

Accepted Answer

Yes — but the transfer adds real work. IATA LAR §11 covers transit clearance: the pet must remain in its sealed container on the tarmac (or in an approved bonded transit area), with a separate manifest endorsement at the hub, plus an acceptance check by the local cargo broker who releases the animal onto the second sector. Common hubs (Heathrow, FRA, ATL, JFK) all have a dedicated live-animal clearance desk. Layover temperature rules apply — if ground temperature at the hub falls outside the carrier’s safe range, the airline reserves the right to reroute or hold the shipment, which is why US-bound transatlantic moves sometimes route via Detroit (DTW) in July instead of Chicago (ORD) to dodge heat embargoes.

Question 7

What happens at a layover when ground ops cannot release the animal because of a weather embargo?

Accepted Answer

The cargo broker at the hub is the decision point. If the next sector is weather-embargoed at departure or arrival and ground ops cannot legally release the animal into the connecting sector, the pet is held in the carrier’s live-animal holding room for the duration of the embargo — on a short delay that means a same-day shipment, on a prolonged closure (a station-wide ground stop) the broker either reroutes to the next available hub or returns the animal to origin. The paid Pet Atlas plan tier includes a hub-substitution call: if the booked hub is forecast to embargo, the plan rebooks onto the closest viable alternate before departure so the animal is never held in transit. Premium-tier plans pre-book profit-cargo space on the alternate so the swap is mechanical, not a panic phone call from the broker.

Question 8

What does the full document package look like for a typical cargo move on one of the five live routes?

Accepted Answer

A complete cargo manifest is seven documents, every one required for the move to clear customs. First, the destination import permit (Brazil MAPA, Australia BICON, or none for UK/EU/Canada depending on route). Second, USDA APHIS Form 7001 (US outbound only, endorsed). Third, the international health certificate issued by an accredited vet within ten days of departure. Fourth, the FAVN titer lab report (Australia + Hawaii only). Fifth, the customs declaration — either USDA e-DBV for EU, EU TRACES for UK, or DAFF BICON for Australia. Sixth, the owner custody affidavit (also known as the person-authorising-consignor letter). Seventh, the airline cargo manifest (AWB) with the live-animal endorsement sticker. Most moves stall because one of those seven is missing or out of date — Pet Atlas builds the checklist on one page, with hard deadlines.

Question 9

What happens if the pet is denied entry at the destination?

Accepted Answer

Denied entry has three flavors. On a UK arrival with missing paperwork, DEFRA can hold the animal at the port for up to 48 hours while the owner supplies documents; failure to do so routes the pet to a DEFRA-approved quarantine kennel at owner expense. On an Australian arrival with a failed FAVN or missing import permit, DAFF re-exports the animal on the next available flight back to origin, entirely at owner cost. On a US arrival, CDC dog import rules (effective 2026 plus the legacy 9 CFR §4 framework) require a CDC Dog Import Permit, a foreign-vaccination microchip, and a CDFA-certified vet signature — failure routes the dog to a CDC-approved quarantine or re-export. The same Pet Atlas plan that pre-empted the problem would have flagged the missing item; if the move is already in motion, calling the carrier’s cargo desk and the destination customs broker simultaneously is the fastest path to a resolution.

Question 10

What is the USDA APHIS endorsement and when is it required?

Accepted Answer

USDA APHIS endorsement is the stamp USDA puts on the international health certificate (Form 7001) after it is issued by an accredited vet. It is required only for moves leaving the United States — not for moves entering the US, and not for in-cabin pet travel under 8 weeks of age. Endorsement lead time runs 3 to 10 business days depending on the Veterinary Services field office queue and whether the certificate is rejected on the first review (a microchip-number typo or a missing vet signature triggers a rewrite, which doubles the lead time). Pet Atlas plans book endorsement at least two weeks before departure so a one-time rejection is absorbed without slipping the travel date.

Question 11

Which of the five live routes need a country-issued import permit and how long does it take?

Accepted Answer

Brazil and Australia — yes, and the permit is on the critical path. Brazil’s MAPA import permit runs 30 days from application to issuance and is owner-named (it cannot be transferred). Australia’s BICON import permit runs six weeks or longer, also owner-named, and is required alongside the FAVN titer. The United Kingdom, Germany, and the EU routes do not need a country-issued import permit for personal pet moves — entry is gated on the vet certificate, the EU commercial regulation 576/2013, and TRACES — but a UK Pet Travel Scheme (PETS) entry is faster with a pre-declared animal. Canada requires no import permit for dogs or cats arriving from the US with a valid rabies certificate; from other origins the CFIA rules apply. Pet Atlas pre-applies for MAPA and BICON before booking the flight so the permit number is on the manifest alongside the AWB.

Question 12

What is the order of operations for a cross-border pet move?

Accepted Answer

Seven steps, in order. Step one: implant the ISO 15-digit microchip (it has to be there before the first vaccine). Step two: give the rabies vaccine (primary at least 28 days before travel from the US; Australian moves add the 180-day clock). Step three: where required, draw the FAVN titer serum and wait for lab result (Australia, Hawaii; 2–4 weeks turnaround). Step four: see the accredited vet for the international health certificate (within 10 days of departure). Step five: where applicable, send that certificate to USDA APHIS for endorsement (US outbound only; 3–10 business days). Step six: secure the destination import permit (MAPA/BICON — six weeks lead time on Australia). Step seven: book the flight and ground transport once the permit number is in hand. Reverse the order and the move stalls.
