Planning a holiday with our best friend is exciting, but before packing the suitcase and buying the ticket, there is one question every pet owner should ask themselves: Is my dog physically prepared for this journey?
In the world of animal behaviour and health, not all dogs experience transport in the same way. The key lies not only in their training but in their DNA. From the shape of their skull to the size they will reach as an adult, genetics dictates the rules of the game, especially when we talk about airline regulations and biological safety.
1. Brachycephalic breeds: The invisible risk of being "flat-faced"
If you have a flat-faced dog, you will know they are adorable, but their anatomy is a challenge for thermoregulation and breathing. Travelling in the hold of an aeroplane poses an extremely high risk of hypoxia (lack of oxygen) and heatstroke for these breeds.
The English Bulldog and French Bulldog: Real flight restrictions
Due to their morphology, many airlines have strictly prohibited their transport in the hold. This is where a dog DNA test becomes a safety tool: if you have a crossbreed dog that suspiciously resembles a Bulldog, confirming a high percentage of this breed in their genes will alert you to take extra ventilation precautions and check if the airline will present legal issues due to their predominant cranial morphology.
The Shih Tzu: Small but vulnerable
We often think that, being small, Shih Tzus have it easy as they can travel in the cabin (where the limit is usually 8 kg). However, their brachycephalic genetics makes them sensitive to cabin pressurisation and, above all, to the stress or anxiety of the flight, which can trigger severe respiratory distress.
2. The challenge of giant breeds: What carrier do I actually need?
One of the biggest headaches for travellers is the IATA-approved carrier. Regulations require that the dog must be able to stand up, turn around, and lie down naturally. If your dog doesn't fit, it doesn't fly.
Great Dane: Predicting growth before the holidays
The Great Dane is one of the most imposing breeds in our database. But what happens if you have adopted a mixed-breed puppy? Guessing their adult size by eye is a game of chance. If, for example, the analysis detects that your puppy has a high percentage of Great Dane, you will know there is a giant breed in their family tree. Although the final size depends on the full combination of breeds and environmental factors, this allows you to plan ahead for the purchase of an XXL carrier.
Spanish Mastiff and Tibetan Mastiff: Stature and bone structure
These breeds are perfect examples of why estimated genetic weight is vital. Their bone structure and large frame require a space that not all aircraft holds can accommodate. Knowing the genetic load of these breeds helps you decide if flying is the best option or if specialised ground transport would better guarantee their wellbeing.
3. Beyond morphology: Travel sickness and temperament
Genetics determines not only how your dog looks, but how they feel.
At Koko Genetics, we believe that knowing your pet's DNA is not just a curiosity; it is preventative medicine and safety. Knowing that your dog has a predisposition to a short muzzle or that they will exceed 40 kg in weight allows you to make informed decisions, choose the right airline and, above all, ensure that the trip is a pleasure rather than a risk.
