A cleft palate is a relatively common condition in dogs (up to 25% incidence). It occurs due to a failure of the roof of the mouth to close during development in the womb. This results in a hole between the mouth and the nasal cavity.

The defect can occur in the lip (primary cleft palate) or along the roof of the mouth (secondary cleft palate). Inside the mouth, the cleft can extend along the bony portion (hard palate), the soft palate at the back of the mouth, or both.

Cleft palate is generally regarded as an inherited condition. As such, purebred puppies, especially those with short noses (Brachycephalic breeds) such as Bulldogs, Boston terriers, Pekingese are more commonly affected than mixed breeds. Occasionally, nutritional deficiencies, viruses, and toxins affecting the mother during pregnancy may increase the risk of puppies being born with cleft palates.


Cleft palate in puppies Prognosis

A cleft palate is generally detected by visual examination of newborn puppies by the veterinary surgeon or breeder. Cleft palate of the lip or hard palate are easy to see, but soft palate defects can sometimes require sedation or general anaesthesia to visualise.
Affected puppies will often have difficulty suckling and swallowing. This is often seen as coughing, gagging, and milk bubbling from the pup’s nose. In less severe defects, more subtle signs such as sneezing, snorting, failure to grow, or sudden onset of breathing difficulty (due to aspiration of milk or food) can occur.


Treatment for cleft palate in puppies

Treatment depends on the severity of the condition, the age at which the diagnosis is made, and whether there are complicating factors, such as aspiration pneumonia.

  • Small primary clefts of the lip and nostril of the dog are unlikely to cause clinical problems.
  • Secondary cleft palates in dogs require surgical treatment to prevent long-term nasal and lung infections and to help the puppy to feed effectively. The surgery involves either creating a single flap of healthy tissue and overlapping it over the defect or creating a ‘double flap’, releasing the palate from the inside of the upper teeth, and sliding it to meet in the middle over the defect. This is a complex surgery, only performed by experienced soft tissue surgeons at our Bolton, Ellesmere Port and, Shrewsbury surgeries. The cost for Cleft Palate surgery at Animal Trust is £1489.

Feeding of affected puppies requires bottle or tube feeding small quantities of milk every 2 hours from birth; older pups may be weaned onto solid foods from as early as 4 weeks of age.

Puppies with aspiration pneumonia will require antibiotics and sometimes hospitalisation, dependent on severity before any surgery can be performed.

Each patient’s individual health concerns and severity of palatal defect will govern the ideal timing of surgery and the technique used. In some cases, more than one surgical procedure may be necessary as the puppy grows and the palate expands.

Ideally, puppies with cleft palates should be tube fed until 3-4 months of age before performing surgery. This allows the puppy to grow to a size where fewer procedures are required and safety under general anaesthesia is greater, whilst limiting the risk of aspiration and allowing adequate nutrition until this time. It also reduces the risk of affecting the adult teeth as they erupt.

Most cases have an excellent long-term prognosis following surgical correction (dependent on severity and location). However, some dogs can have long-term complications even following successful surgery. They can be at increased risk of upper respiratory infections and some may have a chronic nasal discharge that is not definitively treatable. Due to the condition, dogs that have been born with a cleft palate should not go on to have puppies of their own.
