What Is a Brachycephalic Breed?
The term brachycephalic refers to breeds that have a shorter nose and flatter facial structure. This is a normal and recognised breed characteristic.
Some common brachycephalic breeds include:
Dogs: French Bulldogs, English Bulldogs, Pugs, Boston Terriers, Shih Tzus, Boxers
Cats: Persian, Exotic Shorthair, Himalayan, British Shorthair.
Because of their facial anatomy, these breeds benefit from additional space, airflow, and careful planning when travelling, ensuring they remain comfortable throughout their journey.
Understanding BOAS
BOAS, or Brachycephalic Obstructive Airway Syndrome, is a term used to describe a range of upper airway characteristics that can be present in some brachycephalic breeds. These features may affect breathing efficiency, particularly during exercise, excitement, or warm conditions.
It is important to note that not all brachycephalic pets are affected by BOAS. Understanding BOAS simply allows travel to be planned with appropriate care and consideration, helping to minimise risk and maximise comfort.
BOAS-Certified Care You Can Trust
The team at Sky Kennels is fully BOAS certified, and we work closely with our BOAS-certified Official Veterinarians (OVs) who are experienced in assessing and supporting brachycephalic breeds. This means we have a strong understanding of brachycephalic breeds and the specific considerations they may have when travelling. Our experience allows us to plan each journey with care, considering the individual needs of the pet to support comfort, safety, and wellbeing throughout the travel process. We also work alongside trusted airline partners and experienced agents in destination countries. This professional network allows us to manage your pet’s journey smoothly and compliantly from start to finish.
Airline Policies & Travel Planning
There is often confusion around airline policies for brachycephalic pets. While some airlines have specific guidelines, with the correct expertise, careful planning, and appropriate route selection, brachycephalic cats and dogs can travel to the vast majority of countries worldwide. There are very few destinations where travel is not possible at all.
Our role is to guide you clearly and confidently through the process. We will:
- Advise on suitable airlines and routing options
- Explain airline requirements in clear, reassuring terms
- Manage documentation and compliance on your behalf
- Always prioritise your pet’s comfort and welfare
Each journey is planned individually, ensuring it is suitable for the pet involved.
Pre-Travel BOAS Assessment
For added reassurance, we recommend a pre-travel BOAS assessment with your own veterinarian. This allows any relevant airway or health considerations to be identified in advance and ensures travel plans are tailored appropriately.
Sharing this information early helps us create the safest and most comfortable journey possible for your pet.
Specialist Sky Kennels for Brachycephalic Breeds
The right sky kennel plays an important role in your pet’s comfort. In line with IATA Live Animals Regulations (LAR) and IPATA best practice, brachycephalic cats and dogs travel in a sky kennel that is larger than the standard minimum size used for non-brachycephalic breeds.
This additional space allows your pet to stand, turn, and rest naturally, while supporting good airflow throughout the journey.
Every sky kennel we provide here at Sky Kennels meets current IATA requirements for construction, ventilation, security, and sizing, and is selected based on your pet’s individual measurements, breed type, and airline criteria.
A Calm, Welfare-Led Approach
Every pet is unique, and our role is to ensure travel arrangements suit the individual animal. We take time to assess each journey carefully and provide open, honest advice throughout the process.
By choosing Sky Kennels, you are choosing a team that treats your pet with respect, understanding, and care.
