BOAS surgery: helping flat faced dogs breathe

The snoring that everyone calls normal for the breed is a dog working hard for every breath. Airway surgery for frenchies, pugs and bulldogs is one of the most quality of life changing operations in veterinary medicine, and one of the most under discussed until a heat wave makes it an emergency.

What BOAS actually is

Brachycephalic obstructive airway syndrome is a set of anatomical problems stacked in one airway: nostrils narrowed to slits, a soft palate too long for the shortened mouth, a tongue base crowding the throat, and in worse cases saccules and tonsils dragged into the airway by years of effortful breathing. Surgery opens the nostrils and shortens or thins the palate; laser assisted techniques can also address deeper obstruction. Every part addressed reduces the effort of every single breath.

No charge to ask

Wondering if your dog's breathing needs surgery?

Send what your vet said and quoted. A veterinary surgeon reads it and comes back to you with what they can do and what it would cost, before you pay anything. A written second opinion is from $250.

  • If the surgeon can't add anything useful to your case, they'll say so and there's no charge.
  • You hear back from a surgeon within 2 business days.
  • BOAS surgery is quoted from $1,500 to $8,500 in Australia. A surgeon's read on your quote is the cheapest line in this decision.

The spiral argument for acting early

An obstructed airway damages itself: the extra suction of every breath progressively stretches and inflames the soft tissues, pulling more of them into the airway. Young dogs with early surgery often avoid the worst of that spiral. This is why assessment at desexing age, not after the first collapse at age six, is what airway focused vets recommend for the flat faced breeds.

Still deciding? It costs nothing to ask.

Send the case, hear back from a surgeon with what they can do and what it costs, and only pay if you go ahead.

Common questions

My frenchie snores but seems happy. Is that really a problem?

Snoring is noise from an obstructed airway; it is common in these breeds and normal for none of them. The useful tests are exercise and heat tolerance, recovery time after excitement, and sleep quality. Plenty of happy seeming dogs are quietly exhausted, and owners are routinely astonished by the dog that emerges after surgery.

Is the surgery risky for flat faced dogs?

Anaesthesia in brachycephalics demands experience and planning, and the highest risk window is actually recovery, as swelling settles in an already narrow airway. This is a genuine reason to choose teams that do these procedures often and monitor overnight, and a genuine reason the specialist quotes run higher.

Will surgery stop the snoring completely?

Usually it reduces dramatically rather than disappearing. The honest promise is a dog that breathes, sleeps, exercises and handles warmth far better, not a dog with a labrador's airway.
