Cleft palate in brachycephalic dogs: causes, effects & treatment
A cleft palate is a physical birth defect familiar to many because it occurs in babies, but it also affects dogs, particularly in certain breeds. Brachycephalic dogs, those with short, flat faces, are more prone to this hereditary abnormality which can range from mild to severe.
A cleft palate may be visible from the outside or hidden inside the roof of the mouth, impacting a dog's ability to suckle, feed, and thrive. It is essential for potential breeders or those considering adopting such dogs to understand this condition.
In this article, we explore the types of cleft palate found in dogs, their causes, affected breeds, health impacts, treatment options, and ethical breeding recommendations to reduce suffering and improve welfare.
What is a cleft palate?
A cleft palate is an abnormal gap or opening between the nasal and oral cavities, caused by incomplete fusion of tissues during embryonic development. This condition disrupts the normal separation, allowing food and fluids to pass incorrectly.
There are three main types:
- Cleft palate only: an opening in the roof of the mouth affecting the hard and/or soft palate inside.
- Cleft lip only: a visible split or gap usually affecting the upper lip.
- Cleft lip with cleft palate: involving abnormalities of both the lip and the palate.
In brachycephalic breeds, clefts involving the lip combined with palate are common, and puppies with cleft palate often face feeding difficulties and health risks.
What causes a cleft palate in brachycephalic dogs?
Cleft palate in dogs is a congenital condition caused by genetic and environmental factors:
- Genetics: Hereditary conformation defects lead to abnormal skull and facial development in susceptible breeds.
- Environmental risk factors: Maternal malnutrition, exposure to toxins, viral infections or certain medications during pregnancy may increase risk.
It is a multifactorial issue, with interactions between inherited predisposition and pregnancy environment influencing incidence.
Which breeds are most affected?
Brachycephalic breeds are especially at risk due to their distinctive skull shape. Some of the breeds with higher-than-average risk include the Boston Terrier puppies, Pekingese puppies, and English Bulldog puppies. The prevalence of cleft palate in these breeds highlights why responsible breeding avoiding extreme brachycephalic features is crucial.
How does a cleft palate affect a dog's health?
The severity of symptoms depends on the type and extent of the cleft. Dogs with cleft palate often struggle to properly suckle or eat, risking malnutrition and poor growth. A severe cleft may lead to food entering the nasal cavity or lungs, causing aspiration pneumonia—a life-threatening complication.
Early veterinary assessment is essential for puppies showing feeding difficulties or respiratory issues to improve survival chances.
What treatment options are available?
Surgical correction is the primary treatment for cleft palate in dogs. Expertise in oral surgery is required to repair the defective tissues, and surgery usually has a good success rate, especially if performed early. Supportive care, like tube feeding, may be needed before surgery to prevent aspiration.
In cases where surgery is not possible, prognosis is poor, and humane euthanasia might be considered to prevent suffering.
Why is ethical breeding important to prevent cleft palate?
Since cleft palate is hereditary, dogs affected or carriers should never be bred to avoid passing on this deformity. The Kennel Club and veterinary organisations strongly advocate for:
- Responsible breeders avoiding mating dogs with extreme brachycephalic features linked to clefts and other health issues.
- Utilising genetic screening and maintaining genetic diversity in breeding lines.
- Educating prospective owners and breeders about health risks associated with breed conformation.
- Promoting breed standards focusing on health and welfare over exaggerated physical traits.
These measures aim to improve the welfare of brachycephalic breeds and reduce congenital disorders like cleft palate.

FAQs
Can brachycephalic puppies with a cleft palate survive?
Quick Answer: Yes, with early diagnosis and surgical treatment, many puppies with cleft palate can survive and lead good lives.
While cleft palate used to have a poor prognosis, advances in veterinary surgery mean puppies given attentive care and timely repair often thrive. However, without intervention, feeding difficulties and aspiration pneumonia can be fatal, so prompt veterinary care is critical.
How to spot a cleft palate in a puppy?
Quick Answer: Feeding difficulties, nasal discharge when suckling, coughing, or noise during eating can indicate a cleft palate.
Visual inspection inside the puppy’s mouth by a vet is needed for diagnosis, especially for secondary clefts. Any pup struggling to feed normally should be evaluated promptly to prevent complications.
Where to find reputable breeders or puppies?
If you are looking to find a puppy from a brachycephalic breed, ensure you choose reputable breeders who prioritise health and responsible breeding practices. Avoid supporting breeders who select for extreme features that increase risk of congenital problems such as cleft palate.

Conclusion
Cleft palate in brachycephalic dogs is a serious inherited condition that requires understanding, early detection, and often surgical treatment to ensure affected puppies can thrive. Preventing this problem through ethical breeding is essential to safeguard the future health and welfare of these popular breeds.
By choosing responsible breeders and supporting health-focused breeding standards, prospective owners can help reduce the incidence of cleft palate and improve the quality of life for brachycephalic dogs in the UK.
