Does Pet Insurance Cover BOAS Surgery?

The longer answer depends on timing, policy type, and whether your insurer treats BOAS as pre-existing or hereditary. Here is how it actually works.

What Is BOAS?

Brachycephalic obstructive airway syndrome is a group of upper airway abnormalities found in flat-faced dog breeds.

Selective breeding has shortened the skull without proportionally reducing the soft tissue inside it. The result is physical obstructions that restrict airflow through the nose, throat and windpipe.

There are 4 primary anatomical issues: stenotic nares (narrowed nostrils), an elongated soft palate that blocks the windpipe, everted laryngeal saccules pulled into the airway, and a hypoplastic trachea (abnormally narrow windpipe).

These can occur alone or in combination. In mild cases, it sounds like snoring.

In severe cases, it causes breathing collapse.

The University of Cambridge Respiratory Function Grading scheme scores BOAS from 0 to 3. Grade 0 or 1 means clinically unaffected.

Grade 2 or 3 means surgery is typically recommended.

Which Breeds Are Affected by BOAS?

BOAS primarily affects brachycephalic breeds – the flat-faced ones. French Bulldogs, English Bulldogs, Pugs, Pekingese, Shih Tzus and Boston Terriers are the most commonly diagnosed.

Flat-faced breeds are affected most. Our guides to the health problems French Bulldogs face and the health conditions Pugs are prone to put BOAS in the context of each breed.

If you own one of these breeds, understanding the specific health risks and insurance considerations for French Bulldogs or Pug insurance costs is worth doing before symptoms show up.

A 2024 cross-sectional study in PLOS ONE assessed 898 dogs across 14 brachycephalic breeds [1]. French Bulldogs, English Bulldogs and Pekingese had the highest proportion of clinically affected dogs.

Three risk factors stood out: body condition score (overweight dogs had 1.8 times the odds of BOAS), nostril stenosis, and craniofacial ratio. The flatter the face, the greater the risk.

Symptoms can appear in puppies or develop between ages 2 and 4.

Noisy breathing, exercise intolerance, overheating, regurgitation and episodes of collapse are the warning signs.

How Much Does BOAS Surgery Cost in the UK?

BOAS surgery in the UK typically costs between £1,850 and £4,000, depending on which procedures the dog needs, how severe the condition is, and where you go. That is the typical range in the UK, depending on which procedures the dog needs, how severe the condition is, and where you go.

Some fixed-price clinics offer BOAS surgery from around £1,000, but add X-rays or a CT scan and the total climbs.

The 3 most common surgical procedures are alarplasty (widening the nostrils), palatoplasty (trimming the elongated soft palate) and sacculectomy (removing everted laryngeal saccules). A dog that needs all 3 pays more than one that only needs nares widening.

Recovery means 24 hours at the clinic, roughly 2 weeks of rest at home, and 4 to 6 weeks for full healing.

Prices based on UK market averages as of 2026.

Actual costs vary by practice, location and case complexity.

When Does Pet Insurance Cover BOAS Surgery?

Pet insurance covers BOAS surgery when the condition developed and was first diagnosed after the policy waiting period ended – most UK policies apply a 14-day waiting period for illness. Most UK policies apply a 14-day waiting period for illness.

If your dog had no breathing symptoms before that window closed and BOAS is subsequently diagnosed, the surgery falls within your policy terms.

The claim works like any other illness claim. You pay the excess, co-payment applies if there is one, and the insurer reimburses up to the benefit limit.

Lifetime pet insurance may be more suitable in some circumstances.

The annual benefit limit resets each year. That matters if your dog needs follow-up treatment or develops complications months down the line.

When Does Pet Insurance NOT Cover BOAS Surgery?

Pet insurance does not cover BOAS surgery when the condition is classified as pre-existing, when symptoms appeared during the policy waiting period, or when the policy excludes hereditary or breed-related conditions – this is where owners get caught out.

BOAS is excluded as a pre-existing condition if your dog showed any breathing symptoms – snoring, noisy breathing, exercise intolerance – before the policy started or during the waiting period.

Insurers pull veterinary records. A puppy health check where the vet casually writes “noisy breathing” or “stenotic nares” creates a paper trail.

When you later claim for surgery costing thousands, that note is enough. Pre-existing.

Claim denied. It does not matter that nobody formally diagnosed BOAS at the time.

Some policies exclude hereditary and congenital conditions outright.

BOAS has a hereditary component – it exists because of the breed’s skull shape. Owners on breed forums report having claims denied because the insurer classified it as a congenital defect, even though symptoms only appeared well after cover started.

This exclusion hides in the full terms and conditions. People find out about it when the claim comes back rejected.

Accident-only policies do not cover BOAS either.

It is an illness, not an accident.

Does the Type of Policy Affect BOAS Coverage?

Yes, the type of policy significantly affects BOAS coverage, lifetime policies cover ongoing BOAS treatment year on year, while accident-only and time-limited policies leave gaps once limits are reached.

The 3 main UK pet insurance policy types handle it very differently.

Time-limited policies cover BOAS for 12 months from the first claim. After that window closes, you are on your own.

BOAS recovery usually finishes within 6 weeks, but secondary complications can surface months later – and by then, the clock has run out.

Maximum benefit policies cap the total payout per condition. No time limit, but a fixed pot.

Surgery costs £3,000 on a £4,000 limit and you have £1,000 left for anything that follows. If complications push costs higher, the shortfall is yours.

Lifetime policies reset the benefit limit each year upon renewal.

Ongoing cover for complications, monitoring, or a second surgery if needed. For breeds where BOAS is a known risk, this is the policy that does not leave a gap.

How Can You Maximise Your Chance of BOAS Coverage?

You can maximise your chance of BOAS coverage by insuring early, before any symptoms appear and before the policy’s waiting period needs to elapse.

That is the single most important thing. Get cover on your flat-faced puppy within the first few weeks of bringing them home, before any breathing issue has a chance to appear on a vet record.

The owners who run into problems are almost always the ones who waited.

Before buying a policy, confirm in writing that it covers hereditary and congenital conditions. Not all do.

Ask the insurer directly: would BOAS surgery be covered if it developed after the waiting period? Do not rely on the summary.

Read the full exclusions. This one question is the difference between a £3,500 reimbursement and a £3,500 bill you pay yourself.

Watch what your vet writes down.

Phrases like “typical for the breed” or “mild snoring noted” in clinical notes can be used to classify BOAS as pre-existing later. Make sure your vet documents that no respiratory concerns are present at each check-up.

A clean record protects you.

And pick a benefit limit that actually covers the surgery. BOAS plus pre-surgical imaging can hit £4,000 in complex cases.

A policy with a £2,000 limit does not get you there.

What Happens After BOAS Surgery?

After BOAS surgery, most dogs breathe noticeably better within 2 weeks – wider nostrils let more air in, and recovery typically completes within 4 to 6 weeks of restricted activity. Wider nostrils let more air in.

A shortened soft palate stops blocking the windpipe. Removed saccules clear the larynx.

The difference is often dramatic.

The first 10 days involve soft food, restricted exercise, anti-inflammatory medication and watching for swelling. Follow-up vet visits are covered under the original claim, subject to your policy limits.

But BOAS surgery does not change the skull.

It manages the symptoms. Some dogs need a second procedure – scar tissue forms, or one component of the syndrome was not addressed first time round.

Lifetime policies cover this because the annual limit resets. Time-limited policies do not, if the 12-month window has closed.

Weight matters too.

The PLOS ONE study found overweight dogs had 1.8 times the odds of clinically significant BOAS [1]. Keeping your dog lean after surgery reduces airway strain and improves outcomes long term.

BOAS is one of the most expensive conditions flat-faced breeds face, but it is far from the only one.

Choosing dog insurance that covers breed-specific surgical procedures before your pet develops symptoms is the most reliable way to avoid paying thousands out of pocket when a diagnosis arrives.
