What is BOAS and why does it matter for travelling pets?
BOAS or brachycephalic obstructive airway syndrome affects snub nose breeds such as the French bulldog, pug, pekingese, shih tzu, boxer, Boston terrier, Persian, Scottish Fold and British Shorthair. Short muzzles or snub noses are the easiest way to distinguish breeds that are brachycephalic.
If a dog or cat has BOAS then they are at an increased risk of problems with their respiratory systems in general and at a higher risk than their non-snub counterparts when they fly.

You can then get the latest advice on the best routing for your dog or cat plus they will be able to point you in the direction of a vet who can conduct a BOAS assessment to gauge their suitability to fly.
If your pet fails the BOAS assessment then it should not fly unless by private charter, and even then the pet owner should consider carefully the risks of a stressful journey bring.
Many airlines have a blanket ban on certain breeds of dog and cats however there are airlines who will transport snub-nose breeds under strict conditions such as subject to a BOAS fit-to-fly assessment and in a crate larger than normal to facilitate airflow. You may also be limited to the time of year at which your pet can fly due to temperatures on the ground when your dog or cat is being loaded or unloaded.
