Flying with Your Dog in the Hold in Europe: Risks, Rules, and Alternatives
For many dog owners, flying their pet in the aircraft cargo hold feels like an uncomfortable compromise — but for larger dogs that cannot travel in the cabin, it is often the only aviation option available. Understanding the precise regulations that govern this process, what the airlines actually require, and what the genuine risks are will help you make an informed decision about whether hold travel is right for your dog.
IATA Live Animals Regulations (LAR)
The primary international standard governing the air transport of live animals is the IATA Live Animals Regulations (LAR), published annually by the International Air Transport Association. These regulations set out the minimum requirements for container specifications, labelling, documentation, care, and handling of animals transported as cargo. Most airlines operating in Europe adopt the IATA LAR as their baseline standard, and compliance is expected both from the airline and from the pet owner who presents an animal for transport.
The IATA LAR specifies that dogs must travel in containers that meet the requirements of Container Requirement 82 (CR82). Under this standard, the container must be large enough for the dog to stand in natural position, turn around normally, and lie down in a natural position. The container must be constructed of rigid material (fibreglass, metal, or rigid plastic), have adequate ventilation on at least three sides, have a solid floor that is absorbent or covered with absorbent material, and be fitted with secure, tamper-evident fastenings. The door must be secured with a clip-type fastening that cannot be accidentally opened. Water and food dishes must be accessible from outside the container, and live animal stickers must be affixed to the exterior.
Containers made of collapsible or wire mesh are not acceptable under CR82 for hold transport. A label stating "Live Animal" and directional arrows indicating which way is up must be clearly visible on the outside of the crate.
Airline-Specific Policies in Europe
Lufthansa
Lufthansa permits dogs to be transported as checked baggage or cargo depending on the route and the size of the animal. Dogs travelling as checked baggage must be in an IATA-approved container, and the combined weight of dog and container typically must not exceed 50 kg for checked baggage. Larger dogs or those on certain routes must travel via Lufthansa Cargo. Booking must be made in advance — dogs cannot simply be presented at check-in without a prior reservation. Health certificate requirements vary by destination, and all documentation must be in order before the animal is accepted.
Air France
Air France accepts dogs in the hold as registered baggage on most medium- and long-haul routes. The airline requires an IATA-compliant container, a health certificate issued by a licensed veterinarian within 10 days of travel, and advance booking. Specific weight limits and breed restrictions apply, and certain brachycephalic (flat-faced) breeds — including Bulldogs, Pugs, and Boston Terriers — are subject to additional restrictions or may be refused transport due to their elevated respiratory risk during air travel. Air France does not accept dogs as hold baggage on some short-haul routes where cabin transport of small dogs is available instead.
Iberia
Iberia allows dogs to travel in the hold as checked baggage on most routes, subject to advance booking and IATA container compliance. Weight limits for combined dog and container are specified per route and class of service. Iberia also applies breed restrictions for brachycephalic dogs, and owners of affected breeds should contact the airline directly to confirm whether transport will be accepted. Health certificates and compliance with destination country import requirements — including the EU Pet Passport under Regulation 576/2013 for intra-EU travel — are mandatory.
Ryanair
Ryanair does not currently accept dogs or other pets in the hold or the cabin on any of its services, with the exception of trained assistance dogs on certain routes. This is a blanket policy rather than a route-specific restriction. Owners who need to fly within Europe with a dog that cannot use other airlines should consider alternative operators or alternative modes of transport entirely.
Health Certificate Requirements
In addition to the EU Pet Passport required under Regulation 576/2013 for movement between EU member states, most airlines require a veterinary health certificate for dogs travelling in the hold. This certificate, sometimes called a "fit to fly" certificate, must typically be issued by a licensed veterinarian no more than 10 days before the date of travel and must confirm that the animal is in good health, free from signs of infectious disease, and fit for air transport. Some destinations outside the EU have additional requirements that must be documented separately.
Temperature Embargoes
One of the most significant practical limitations of hold travel for dogs is the temperature embargo. Airlines will refuse to transport live animals in the hold when ground temperatures at the origin or destination airport fall below or rise above specified thresholds. In practice, this means that in summer, dogs may be refused transport during heatwaves, and in winter, they may be refused during freezing conditions. These embargoes are applied for animal welfare reasons — hold compartments are climate-controlled during flight but are exposed to ambient temperatures during ground handling, which can be dangerous. Owners should be aware that bookings can be cancelled at short notice due to temperature restrictions, even if all other documentation is in order.
The Veterinary Position on Sedation
Many dog owners instinctively consider sedating their dog for a hold flight to reduce stress. However, the veterinary consensus is strongly against the use of sedatives or tranquillisers for dogs travelling in the cargo hold. Sedation affects an animal's ability to maintain balance and natural posture, and alters cardiovascular and respiratory function — effects that are compounded at altitude. A sedated dog that falls or becomes distressed in the hold cannot right itself or signal distress in the way an alert animal can. Veterinary organisations including the British Veterinary Association and the American Veterinary Medical Association have both issued guidance advising against sedation for air travel. If your dog is too anxious to travel unsedated, this is a strong signal that hold air travel is not appropriate for that animal.
The Real Risks of Hold Travel
Hold travel is not without genuine risk, and owners should approach it with clear eyes. Dogs with respiratory conditions, heart disease, or extreme anxiety are poor candidates. Brachycephalic breeds face elevated risk due to their compromised airways. Older dogs and very young puppies are also more vulnerable. Incidents during hold transport, while statistically uncommon when IATA standards are followed, do occur — and the dog is alone and unable to be monitored during the flight. For many dogs, the stress of the experience is significant even without a medical incident.
Alternatives to Hold Air Travel
- Train travel within Europe is well-developed and dog-friendly on many operators including DB, SNCF, Renfe, and Trenitalia, with dogs typically permitted on a lead or in a carrier for a modest supplement.
- Ferry services across the Channel, the Baltic, and the Mediterranean frequently accept dogs, often in on-board kennels or in accompanying vehicles, providing a far less stressful alternative for animals that do not enjoy confinement.
- For shorter routes, driving remains the most controllable and least stressful option for most dogs.
- Specialist pet transport companies exist that manage door-to-door transport via road and ferry, which may be worth considering for long international relocations.
Choosing the Right Crate
If hold travel is genuinely the only viable option for your journey, selecting an IATA CR82-compliant crate and acclimatising your dog to it well in advance is essential. Zooplus stocks a range of IATA-approved travel crates in sizes suitable for breeds from small terriers to large breeds such as Labradors and German Shepherds. Begin crate training several weeks before travel, feeding your dog in the crate and allowing them to sleep in it voluntarily, so that the crate becomes a familiar and secure environment rather than a source of stress.
The decision to fly your dog in the hold should never be taken lightly. For many dogs and many journeys, there is a better way to travel — and it is always worth exhausting those alternatives before committing to the hold.
