Flying bulldogs, pugs, and other snub-nosed dogs
Breeders ship Frenchies, bulldogs, and pugs by air all the time. It is a normal way to place a puppy with a buyer across the country. What trips people up is the carrier: passenger airlines stopped taking these breeds, because a short muzzle means a compressed airway and poor heat tolerance, and the airlines wrote them off the manifest rather than manage the risk. We ship them across Canada on CargoJet instead, and the reason that works is not a loophole. CargoJet flies overnight, and heat is the entire problem.

Why the night flight is the whole answer
Dogs cool themselves by panting. A snub-nosed dog has less airway to do it with, so it sheds heat more slowly than a long-nosed dog of the same size. That is the entire reason these breeds are flagged for air travel. The danger is not altitude and it is not the flight itself. It is heat and stress on the ground.
Almost all of that exposure happens before wheels-up: the drive in, the wait at the warehouse, the ramp, the hold before the doors close. On an afternoon passenger flight in July, that is the hottest part of the hottest part of the day.
CargoJet's network is built to move freight overnight, and the published schedule shows it. Their Hamilton departures leave in the small hours of the morning, and the westbound returns push off in the late evening. The dog does the entire journey through the coolest hours available. That is not a workaround, it is the single most effective thing you can change about the trip.
The flights themselves are also shorter than people picture. Moncton to Hamilton is under two hours. Hamilton to Calgary is about three and a half. Hamilton to Vancouver, the longest domestic run on the network, is roughly five. A snub-nosed dog is not spending a day in the air.
It does not make the breed invincible. Temperature embargoes still apply and we still say no on bad days. Compare ground against air cargo before you decide.
Four things we do for snub-nosed dogs
- 1Size the crate up, not down
More airflow and more room to reposition. We go past the IATA minimum for these breeds rather than meeting it exactly.
- 2Watch both forecasts, not just one
Origin and destination. A comfortable evening at YQM means nothing if the dog is landing into a hot morning at the other end.
- 3Tight drop-off, minimum waiting
Drop-off is three hours ahead of the scheduled flight. We do not park a brachycephalic dog at a warehouse any longer than the carrier requires.
- 4Recommend the drive when the drive is better
Under about twelve hours, ground transport usually wins on cost and always wins on control. For a fragile or very young puppy we will say so even when flying is an option.
FAQs
Why do airlines refuse snub-nosed dogs?
Brachycephalic breeds have compressed airways. A dog with a short muzzle cannot pant as efficiently as a long-nosed dog, and panting is how dogs shed heat. Put that dog somewhere warm and stressful and the risk of respiratory distress climbs. Passenger airlines responded to that risk by excluding the breeds outright rather than managing the conditions. The underlying concern is real. The blanket refusal is a policy choice.
So how is flying them on CargoJet any safer?
Because heat is the actual risk, and the night flight removes most of it. CargoJet runs an overnight freighter network, so the crate moves during the coolest hours of the day instead of sitting on an afternoon ramp. Combine that with a climate-controlled hold and a short domestic flight and you have addressed the specific thing that makes brachycephalic air travel dangerous.
Are there still days you will not fly them?
Yes, and we will tell you no. Live animal cargo is embargoed when ground temperatures fall outside safe ranges, and summer and winter both produce recurring embargoes. For a snub-nosed dog we are more conservative than the minimum, not less. If the forecast at either end is wrong for the breed we move the date or we drive instead.
Does a French bulldog need a health certificate to fly inside Canada?
No. A domestic CargoJet flight inside Canada requires no health certificate and no vaccination records. That saves an appointment and at least $100. Cross-border shipments into or out of the United States are a different matter entirely and do need the full paperwork, which we handle.
What crate should a snub-nosed dog fly in?
An IATA Live Animal Regulations crate, and for these breeds we push toward the larger end of the size range rather than the minimum. More airflow and more room to reposition matter more for a dog that struggles to cool itself. The dog must be able to stand fully upright, turn around, and lie down naturally.
Would you ever tell me to drive instead of fly?
Yes, regularly. For trips under roughly twelve hours of driving, ground transport is usually comparable in cost and gives you a dedicated vehicle, real-time updates, and no temperature embargo to plan around. For a fragile or very young snub-nosed puppy we will often recommend the drive even when the flight is available. We would rather lose the air booking than push a breed onto a plane it does not need to be on.
