Flat-faced pets have become hugely popular in the UK over the last two decades. Breeds like French Bulldogs, Pugs and Persian cats are loved for their distinctive looks and affectionate personalities. But their unique features can also bring certain health challenges.
Many brachycephalic pets are affected by breathing difficulties and other long-term conditions linked to their shortened skull shape. By understanding the risks, you can recognise potential problems early and help your pet enjoy the best possible quality of life.

Brachycephalic syndrome – often called brachycephalic obstructive airway syndrome (BOAS) – is a group of airway abnormalities commonly seen in flat-faced pets.
Because these animals have shorter skulls and compressed airways, breathing can become more difficult.
Common issues include:
These conditions can range from mild to severe and often worsen over time.

Some flat-faced pets show symptoms from a young age, while others develop more noticeable problems later on.
Common signs include:
Many owners assume snorting and snoring are normal for flat-faced breeds, but they can actually be signs of restricted breathing.

Brachycephalic pets can also be more prone to a range of related health conditions.
Their prominent eyes and shallow eye sockets can increase the risk of:
Because their jaws are shortened, teeth may become overcrowded.
This can lead to:

Deep facial folds can trap moisture and bacteria, causing:
Some breeds may develop spinal abnormalities or neurological issues linked to their body shape.
Breathing difficulties can make exercise harder, increasing the risk of weight gain – which in turn can worsen BOAS symptoms.

According to Blue Cross, brachycephalic breeds make up about a fifth of the nation’s dogs – roughly two million.
Flat-faced pets experienced a surge of popularity over the last two decades – in many cases influenced by social media, celebrities and advertising.
Although recent figures suggest a slowing of this trend. According to The Kennel Club in 2023, there were 42% fewer registrations of Pugs, 39% fewer of English Bulldogs and 34% fewer of French Bulldogs.
Dan O’Neill is Chair of the Brachycephalic Working Group (BWG), comprising vets, national animal welfare organisations, scientists and dog breed clubs. He said:
“We hope this is a sign that more and more puppy buyers, owners and breeders are considering the serious health and welfare implications for flat-faced dogs.
“This is particularly important if these dogs are bought on an impulse because they ‘look cute’ but without proper understanding of their potential health issues or how indiscriminate breeding to meet demand results in poor welfare.”

Many popular dog breeds fall into the brachycephalic category.
Some pet insurers may apply restrictions or exclusions to certain brachycephalic breeds, so it’s always worth checking policy details carefully.

Brachycephaly is less common in cats, but several breeds are affected.
Popular flat-faced cat breeds include:
Some other breeds – including British Shorthairs and Scottish Folds – may also show brachycephalic characteristics.

Vets diagnose brachycephalic syndrome through a physical examination and assessment of your pet’s breathing.
They may check:
In some cases, sedation or imaging may be needed to fully assess the airway and determine how severe the condition is.

Treatment depends on how badly your pet is affected.
Keeping your pet slim is one of the most important ways to reduce symptoms.
Your vet may recommend:

Short-term treatments can include:
For more severe cases, surgery may help improve airflow and quality of life.
Common procedures include:
Many dogs show significant improvement after surgery, especially when treated early.

The cost of BOAS surgery can vary depending on:
In the UK, prices tend to cost between £1,100 and £2,300 according to the charity All Dogs Matter. But more complex procedures can cost considerably more.
Costs might include:

Some pet insurance policies may cover surgery for brachycephalic obstructive airway syndrome, depending on the policy terms and whether the condition is classed as pre-existing.
