Great Danes & Giant Breeds: Oversize Pet Cargo

Most advice on flying a large dog is written for Labradors and German Shepherds. Those dogs sit inside the biggest crate any pet shop stocks, so the guidance stops at “buy the large one and measure carefully”.

A Great Dane does not fit that world. Neither does a Saint Bernard, an English Mastiff, a Newfoundland or an Irish Wolfhound. Once the required container passes the largest moulded plastic crate on the market, the file changes category. You are no longer buying a crate; you are commissioning one. And a commissioned crate has a build time, a timber standard, a chargeable weight and a height that some aircraft simply cannot swallow.

This guide walks through what the rules actually measure in giant breed dog shipping, why plastic stops working, what the resulting box does to your freight bill and your route, how to order one that will pass acceptance, and the health risks that come with a very large body. My Pet Mover books oversize dogs out of Kuala Lumpur across our international pet transport routes, and the same three questions come up every time. The video below follows one large dog through a real cargo move.

Kennel clubs sort breeds by weight. Airlines and ground handlers sort them by cubic centimetres. The two do not agree, and the disagreement catches owners out.

A Rottweiler can weigh 55 kg and still fit an off-the-shelf crate because it is a compact, low-slung dog. An Irish Wolfhound weighing less can need a container 20 cm taller, because the height that matters is measured to the top of the head or the ear tip in a natural standing position, whichever is higher.

• Height decides the category, not mass. Two dogs of identical weight can land in completely different crate bands if one is tall and narrow and the other is broad and low.
• Length is the second constraint. Nose-to-tail length plus half the elbow height sets the floor of the box, which is what eats hold space.
• Width is usually the easiest. Shoulder width doubled gives the internal width, and even on a Mastiff that number stays manageable.

This is the mirror image of the problem faced by owners at the other end of the scale, where being small buys a cheaper crate band but still no seat, as we covered in the guide to toy breeds and cabin flights. Size changes the economics in both directions; it never changes the fact that the dog flies in the hold.

The written standard is Container Requirement 1 in the IATA Live Animals Regulations. It permits fibreglass, metal, rigid plastic, solid wood or plywood, then adds a caution that matters enormously here: rigid plastic containers are suitable for most breeds of dog, but their acceptability is at the discretion of the operator, and some rigid plastic containers may not be suitable for large dogs.

That sentence is why giant breed dog shipping so often ends in a joinery workshop rather than a pet shop. Two practical failures drive it:

1. Nothing is moulded that large. The largest widely stocked plastic crate gives roughly 117 cm of internal length and 84 cm of internal height. Most adult giant breeds need more of both.
2. Shell strength stops scaling. A moulded shell that holds a 40 kg dog does not automatically hold a 75 kg one, and a bolted-on height extension changes the structure the manufacturer tested.

Wood is the accepted answer, and the standard is specific about it. For dog containers, the minimum thickness of the sides is 12 mm and the roof must also be at least 12 mm, with welded wire mesh of 2.5 mm or thicker. Containers made entirely of wire mesh are not acceptable at all.

Above the largest moulded crate, there is no product to buy. There is only a container to build.

The published container requirement for dogs and cats gives the formula and stresses that the results are internal dimensions and are a floor, not a target. The dog must still be able to stand, sit erect, lie naturally and turn around normally. Here is what the arithmetic produces for typical adults.

Two patterns stand out. The Great Dane and the Irish Wolfhound are the tall problems, and the Mastiff and Saint Bernard are the wide, heavy problems. They fail the same test for different reasons, and the fix differs accordingly.

The formula and the divisor are industry standard. As Maersk’s explanation of chargeable weight sets out, the 6,000 divisor is the IATA standard and the carrier bills whichever number is larger. Some carriers apply 5,000 instead, which makes a bulky consignment cost more again.

Read the last two columns together and the lesson is blunt. A Mastiff that genuinely weighs 130 kg with its crate is billed as though it weighed 205 kg. Nothing you feed or fast the dog changes that. Only trimming genuine centimetres off the box does, which is exactly why the build should be sized to the dog rather than rounded up for comfort.

This is the single largest reason a giant breed dog shipping quote looks unlike the numbers in our general guide to what it costs to fly a dog overseas. The rate per kilo is normal; the kilos are not.

Lufthansa Cargo puts the point mildly in its own live animals FAQ: the service is normally available across the network, but restrictions can apply depending on the aircraft used on a route, and large animals on freighters are always carried on the main deck. Translated into a Malaysian departure, that means a route that works in June on a wide-body may not work in September when the schedule swaps to a smaller aircraft.

Practically, three things get checked before anyone quotes an oversize dog:

• The aircraft on your exact flight number and date. Not the airline’s general policy, and not the aircraft flown last month.
• Whether the routing has a transit stop. A change of aircraft mid-journey means the crate has to clear two hold profiles, not one.
• Whether the destination terminal can receive it. Handling a 200 kg volumetric consignment needs equipment at both ends.

The list of carriers that take animals out of Kuala Lumpur at all is the starting point, and we keep it current in the guide to which airlines carry pets to and from Malaysia. On long-haul European files such as a Malaysia to Germany pet relocation, the aircraft question usually settles which of two or three viable routings is actually bookable.

The middle two bands are where owners lose the most time, because the answer is genuinely “it depends on the flight”. A dog whose crate measures 99 cm and one whose crate measures 103 cm can end up on completely different itineraries, which is why an accurate standing height early matters more than any other single number on the file. Well-proportioned large breeds such as a Golden Retriever moving overseas from Malaysia never meet this constraint at all.

How to commission a giant breed flight crate

Working through these six steps in order avoids the two expensive failures: a box that is refused at acceptance, and a box that is bigger than it needed to be.

1. Measure the dog properly. Nose to base of tail, ground to elbow, width across the widest point, and floor to the top of the head or ear tip while standing naturally. Do it on a hard floor, not on a rug.
2. Apply the formula and stop there. Length equals nose-to-tail plus half the elbow height, width equals shoulder width doubled, height equals standing height plus bedding. Resist adding “a bit extra” — every extra centimetre is billed.
3. Specify treated timber. All wood used for containers in international transport must comply with IPPC standards, so the workshop must use timber carrying the ISPM 15 treatment mark. Untreated timber can be refused or destroyed on arrival.
4. Set the build standard in writing. Sides and roof at least 12 mm thick, welded wire mesh at least 2.5 mm, one whole end of the container in welded wire mesh, metal nuts and bolts rather than plastic clips, and a solid leak-proof floor.
5. Get the ventilation and spacers right. Ventilation on all four sides, at least 16 per cent of the total side surface, concentrated over the upper two-thirds. Spacers along both long sides and the back, plus forklift spacers of at least 5 cm once the loaded container exceeds 60 kg.
6. Fit food and water bowls before conditioning starts. A water container must be fixed inside with outside access for filling, and water has to be available if the journey exceeds 12 hours. Then give the dog six to eight weeks to live with the box.

Build time is the part owners underestimate. A workshop needs the measurements, then time to cut, assemble, treat and fit out, and the dog needs the crate at home well before flight day. Our overview of pet export from Malaysia sets out how the crate build slots alongside the permit and veterinary work.

Notice what does not change. The rabies waiting period is the same for a Chihuahua and a Wolfhound, because it belongs to the destination’s law rather than to the animal. What a giant breed adds is roughly four to eight extra weeks at the front of the file, and that is time you can only buy by starting earlier. The final morning itself follows the same pattern we describe in the walkthrough of pet cargo at KLIA on flight day, just with more equipment involved.

The container rules are explicit that tranquillisation is not recommended, because common tranquillising drugs lower blood pressure, which already happens at a cabin altitude equivalent to roughly 8,000 feet. Lufthansa Cargo states it more bluntly still, warning that tranquillising an animal can be fatal in air travel. On a giant breed, where circulation and thermoregulation are already working harder, that advice is not a formality.

Three risks deserve specific planning:

• Gastric dilatation and volvulus. Deep-chested breeds such as Great Danes are the classic bloat risk. Feed a light meal at least two hours before dispatch and never a large one, and follow your vet’s guidance on timing.
• Heat load before the dog ever boards. The Malaysian apron is hot, a big body sheds heat slowly, and the crate is closed. Early-morning or late-evening departures help materially.
• Joints and standing time. An older Mastiff or Newfoundland may find a long stand painful. Absorbent bedding with genuine cushioning is worth the extra centimetre of height it costs.

None of this makes the hold dangerous. Live-animal holds are heated and ventilated, a point we cover in detail in our look at whether pets travel safely in the cargo hold. The risks above are body-shape risks, in the same way that a long-backed dog carries spinal risks of its own, as set out in the guide to flying a Dachshund overseas.

Nothing about a Great Dane makes it unfit to fly. Giant breeds move internationally out of Kuala Lumpur regularly and arrive in good order. What makes the file harder is that a single number — standing height plus bedding — cascades into the crate build, the chargeable weight, the aircraft, the routing and the calendar.

Get that number early and everything else becomes an ordinary planning exercise on our international pet transport routes. Guess at it, and you find out at acceptance.

1. Is there a maximum size of dog that can fly?

There is no published weight limit that rules out a breed. The practical limit is the container: once the crate is taller or longer than the aircraft’s hold and cargo door allow, that flight cannot take it. A different aircraft or a freighter usually can, so the constraint is on the routing rather than on the dog.

2. Can I use a plastic crate with a height extension for my Great Dane?

Often no. The regulations note that some rigid plastic containers are not suitable for large dogs and that acceptability is at the operator’s discretion. An extension also changes the structure the manufacturer built, so many carriers refuse it. A purpose-built wooden container is the reliable route.

3. Why is the quote so much higher than for a Labrador?

Because air freight bills on the higher of actual and volumetric weight, and volumetric weight is the crate’s length times width times height divided by 6,000. A giant-breed crate can generate 185 to 205 kg of chargeable weight even though the dog and crate together weigh far less.

4. How far in advance should I start for a giant breed?

Giant breed dog shipping needs four to eight weeks more than a standard dog would. The crate build takes three to five weeks, conditioning needs six to eight weeks on top, and confirming aircraft space for an oversize consignment commonly takes three to six weeks rather than one or two.

5. Does the crate have to be made of treated wood?

Yes, if it is timber and the journey is international. All wood used in containers for international transport must comply with IPPC standards, meaning it must carry the ISPM 15 treatment mark. Untreated timber risks refusal or destruction at the destination.
