Snub-nosed dogs and cats: the airline decides, and often says no

Last verified: 2026-08-26

The answer

Australia does not restrict snub-nosed breeds. Nothing in its import conditions turns on skull shape. The obstacle is entirely on the airline side, and it can be absolute.

One carrier’s published position, authoritative for that carrier only:

Brachycephalic (snub-nosed) dogs, cats and their mixes are not permitted on Delta or Delta Connection flights.

Not “restricted in summer” — not permitted. Other carriers draw different lines, some seasonal, some by breed list, some by weight. There is no general rule to learn; there is your carrier’s rule to obtain in writing.

Which animals this affects

Short-muzzled breeds and their mixes: pugs, French and English bulldogs, boxers, Boston terriers, shih tzus, Pekingese, and among cats the Persian, Himalayan and exotic shorthair, along with crosses of any of them.

Note the phrase “and their mixes” in the quoted policy. A dog whose paperwork says “terrier cross” but whose face is short can be refused on the appearance in front of the handler — the same logic that makes prohibited-breed determinations uncomfortable at the Australian end.

Why airlines take this position

Brachycephalic animals have compromised airways. Heat, stress and reduced airflow — all normal features of cargo handling and ground time — raise the risk of respiratory distress, and carriers have lost animals. The 2026 IATA standard treats carrier rules as varying by carrier precisely because each has made its own judgement about that risk.

Temperature limits compound it. The same carrier will not ship any pet when ground temperature exceeds 27°C or falls below −7°C, which narrows the workable dates for a long-haul routing.

What to do, in this order

1. Establish acceptance before anything else. If you have a snub-nosed animal, find out which carriers will board it on your route before starting the six-month preparation. This is the one case where the airline question comes first.
2. Ask about mixes explicitly, and how the carrier decides.
3. Expect to pay for routing, not convenience. Fewer legs, cooler months, and a carrier that accepts the animal may cost more than the itinerary you would have chosen.
4. Talk to your veterinarian about fitness, separately from whether an airline will take the booking. Permitted is not the same as advisable.
5. Consider a professional shipper. When route selection turns on which carrier will accept your animal, that is exactly the work a shipper does weekly and you would do once.
