Airway Surgery for French Bulldogs, English Bulldogs, and Brachycephalic Dogs in Boston

Advanced BOAS evaluation and surgical treatment to help your dog breathe easier, recover safely, and live more comfortably.

The Sound You’ve Gotten Used To

When you live with a flat-faced breed, you get used to the noise. The snorting on walks. The loud, rattling sleep. After a while, it just becomes your dog’s personality. You might even think it’s funny or endearing.

But that sound is your dog working harder than they should to move air in and out of their body. Some of these dogs have been struggling to breathe their entire lives. They don’t know what easy breathing feels like, and because it’s always been this way, neither does their owner.

The moment that changes everything is after surgery. Owners hear something they’ve never heard before: quiet. Their dog is breathing calmly, easily, without effort. Many owners get emotional because they didn’t fully understand how much their dog was struggling until the struggling stopped.

This isn’t about guilt. You didn’t cause this, and loving a brachycephalic breed doesn’t make you a bad owner. But understanding what’s actually going on inside your dog’s airway means you can do something about it. Even if you’re not sure whether your dog’s breathing is normal, a consultation can give you a clear answer.

What Is Brachycephalic Obstructive Airway Syndrome (BOAS)?

Brachycephalic Obstructive Airway Syndrome is a condition caused by the way flat-faced breeds are built. These dogs were bred with shortened skulls, but the soft tissue inside their airways didn’t shrink to match. The result is a collection of structural problems that make it physically harder for your dog to breathe.

Think of it like trying to breathe through a straw that’s too narrow. Now imagine doing that all day, every day, while eating, sleeping, playing, and trying to cool down in the heat. The most common problems include narrow nostrils that restrict airflow before it even reaches the throat, an oversized soft palate (the flap of tissue at the back of the throat) that hangs into the airway and blocks it, and excess tissue inside the throat that gets pulled into the airway with every breath.

Not every flat-faced dog has severe BOAS. Some have mild symptoms that don’t significantly affect their quality of life. But for many, the condition is moderate to severe and gets worse over time, not better. The harder your dog works to breathe, the more inflammation and tissue damage occurs inside the airway, which makes breathing even harder. Early intervention prevents that cycle from progressing.

What Are the Signs My Dog May Need Airway Surgery?

Many owners aren’t sure whether their dog’s breathing is a problem or just “how they are.” Here’s what to watch for:

  • Loud breathing or snoring, even when awake and at rest
  • Gagging, retching, or regurgitating while eating or drinking
  • Overheating quickly, even in mild weather or with light activity
  • Collapsing, turning blue, or refusing to keep walking during exercise
  • Restless sleep, or needing to sleep sitting up or with their chin propped on something to keep their airway open
  • Episodes where breathing suddenly gets dramatically worse, especially when excited or stressed

Some dogs show one or two of these signs. Some show all of them. Not every dog with noisy breathing needs surgery, but every dog showing these symptoms deserves an evaluation to find out how compromised their airway is and whether intervention would improve their life.

What Does BOAS Surgery Involve?

BOAS surgery isn’t a single procedure. Our surgeons evaluate your dog’s specific anatomy and address the combination of problems that are restricting their airway. Most BOAS corrections include some or all of the following:

Widening the nostrils (stenotic nares correction) Many brachycephalic dogs have nostrils so narrow they’re nearly pinched shut. Opening them up allows significantly more air to flow in with each breath, reducing the effort your dog has to put into breathing before air even reaches the throat.

Trimming the soft palate (folded flap palatopexy or staphylectomy) The soft palate is the flap of tissue at the back of the throat. In flat-faced breeds, it’s often too long and too thick, hanging down into the airway and partially blocking it. Trimming it to the right length clears the obstruction and lets air move freely into the windpipe.

Removing excess throat tissue (everted laryngeal saccule and/or palatine tonsil removal) When a dog struggles to breathe for months or years, the tissue inside the throat can get pulled and stretched into the airway, creating additional blockages. Removing this excess tissue opens the airway further.

Some dogs need all three corrections. Some need one or two. The specific combination depends on what our surgeons find during your dog’s evaluation, which may include a CT scan or a sedated airway exam to see exactly what’s happening inside the throat.

Your consultation includes a thorough exam and evaluation of your dog's breathing, both awake and potentially under light sedation so the surgeon can see exactly what's happening inside the airway. If a CT scan would help with surgical planning, that can be performed at CORE. You'll leave with a clear picture of how compromised your dog's airway is and whether surgery would make a meaningful difference.
 The critical period is right after surgery, when swelling inside the airway is at its highest. In some cases, swelling after airway surgery can temporarily make breathing difficult during the initial recovery period. If your surgeon anticipates this risk, they may place a temporary tracheostomy tube, a small breathing tube inserted into the windpipe through the neck that allows your pet to breathe comfortably while the surgical site heals. The tube is typically only needed for a short time, usually 24 to 48 hours, and is removed once the swelling has gone down enough for your pet to breathe normally through their airway. This is a precautionary step, not a complication, and it's one of the reasons airway surgery is safest in the hands of a team experienced in managing these patients. Our team monitors your dog closely through this window to make sure they're breathing comfortably and safely before they go home. We always monitor your dog for the 24 hours post-procedure in our critical care unit, with additional oxygen support as necessary to keep them comfortable. What to Expect for Airway Surgery at CORE Full recovery takes about 2 to 4 weeks. During that time, your dog eats soft food, avoids strenuous activity, and stays cool and calm. The first few days require the most attention as the swelling goes down. After that, most owners start noticing changes they didn't expect: their dog sleeps quietly for the first time, eats without gagging, walks without overheating, and has energy they've never shown before. Our goal is to give your dog the experience of easy, comfortable breathing, maybe for the first time in their life.

Frequently Asked Questions

How do I know if my French Bulldog’s breathing is normal?

If your dog snores loudly while awake, gags while eating, overheats easily, or can’t exercise without gasping, their breathing likely isn’t normal. Many owners assume these sounds are just part of the breed. A consultation can tell you exactly how restricted your dog’s airway is and whether they’d benefit from correction.

Is BOAS surgery safe?

Yes, when performed by a board-certified surgeon with an experienced anesthesia team. Airway patients require careful anesthetic management and close post-operative monitoring because of swelling risks, which is exactly why this surgery belongs in the hands of a specialist.

Can flat-faced cats have BOAS surgery too?

Yes. Brachycephalic breeds like Persians, Himalayans, Exotic Shorthairs, and Burmese can develop many of the same airway problems as flat-faced dogs, including narrow nostrils and an elongated soft palate. Cats tend to show subtler signs like noisy breathing, snoring, open-mouth breathing, or reduced activity. If your cat is a brachycephalic breed and showing signs of breathing difficulty, a surgical evaluation can determine whether airway correction would help.

What’s the difference between mild and severe BOAS?

Mild BOAS may mean occasional noisy breathing that doesn’t significantly affect your dog’s daily life. Severe BOAS means your dog is chronically struggling to breathe, overheating frequently, and at risk during exercise, excitement, or warm weather. Our surgeons will grade your dog’s condition at the consultation and explain what intervention, if any, would help.

Will my dog still snore after BOAS surgery?

Most dogs are dramatically quieter after surgery, but some mild noise may remain depending on their anatomy. The goal isn’t silence. It’s comfortable, easy breathing. Most owners are amazed at the difference, even if their dog isn’t perfectly quiet.

My dog collapsed while playing. Is that an emergency?

Yes. A dog that collapses during activity, turns blue, or can’t catch their breath needs immediate veterinary attention. Go to your closest emergency clinic first. Once your dog is stable, contact CORE to discuss whether airway surgery can prevent it from happening again.

Can BOAS get worse if left untreated?

Yes. The harder your dog works to breathe, the more inflammation and swelling develop inside the airway over time. Tissue that was once soft and flexible can become thickened and stiff, creating additional blockages. Early intervention helps prevent this progressive damage and gives your dog the best chance at long-term comfortable breathing.
