What to Do When Your Puppy Has a Cleft Palate: A Complete Guide for Pet Parents

Discovering that your new puppy has a cleft palate can feel overwhelming, especially when you’re not sure what it means for their health or quality of life. You’re not alone in facing this situation, and the good news is that with the right care and veterinary support, many puppies with cleft palates go on to live happy, fulfilling lives. This guide is here to help you understand what’s happening, what to watch for, and exactly what steps to take next.

Common Causes

A cleft palate is a congenital condition, meaning it develops before birth during the puppy’s early formation in the womb. It occurs when the two sides of the palate — the roof of the mouth — fail to fuse together properly, leaving a gap or opening that can range from minor to severe. In some cases, this opening extends to the lip as well, a condition known as a cleft lip or “harelip.”

Palate fusion is a delicate process that happens during a narrow window of fetal development, typically in the first few weeks of gestation. Any disruption to this process — whether genetic, environmental, or nutritional — can result in incomplete closure. Because this window is so brief and precise, even a short-term insult to the developing embryo can have lasting consequences. This is why veterinarians and breeders pay close attention to the health and nutrition of pregnant dogs, particularly during early pregnancy.

Understanding what leads to this condition can help breeders and pet owners make more informed decisions going forward. Common causes include:

• Genetics and hereditary factors: Certain breeds are more predisposed to cleft palates, including Bulldogs, Boston Terriers, Beagles, Cocker Spaniels, and Dachshunds. In these breeds, the condition can be passed from parents to offspring.
• Nutritional deficiencies during pregnancy: A lack of folic acid or other key nutrients in the mother’s diet during pregnancy has been linked to improper palate development in puppies.
• Exposure to toxins or medications: If a pregnant dog is exposed to certain chemicals, steroids, or medications — particularly during the first trimester — it can interfere with normal fetal development.
• Viral infections during pregnancy: Infections that affect the mother dog while she is pregnant can disrupt the development of her puppies, including proper formation of the palate.
• Unknown or multifactorial causes: In many cases, no single cause is identified. The condition may result from a combination of environmental and genetic factors that are difficult to pinpoint.

When a cleft palate is diagnosed in a puppy, your veterinarian will typically take a thorough history of the mother’s pregnancy — including her diet, any medications she received, potential toxin exposures, and whether she experienced illness during gestation. There are no specific prenatal imaging tools routinely used in dogs the way ultrasound is used in human medicine, so diagnosis is almost always made after birth through physical examination. In breeding programs where cleft palates have appeared before, genetic counseling and selective breeding practices are the primary tools for reducing recurrence.

It’s also worth noting that cleft palates do not follow a seasonal pattern, nor are they more common in puppies born at a particular time of year. They can and do occur in any litter, at any time — which is why newborn exams for every puppy in a litter are so important, regardless of breed or perceived risk.

Symptoms to Watch For

Cleft palates are sometimes visible at birth, but in other cases — particularly when the opening is located further back in the mouth — they can be easy to miss during a casual look. Knowing what signs to watch for in a young puppy is critical, because early detection makes a significant difference in outcome.

Common symptoms and warning signs include:

• Difficulty nursing or feeding: Puppies with a cleft palate often struggle to create the suction needed to nurse from their mother. This is frequently the first noticeable sign.
• Milk or formula coming out of the nose: This is one of the most telltale symptoms. Because the palate is incomplete, liquid can travel up into the nasal cavity and drain from the nostrils.
• Coughing, gagging, or choking during feeding: Aspiration of milk is a serious risk and can cause persistent coughing or gagging after every feeding attempt.
• Poor weight gain or failure to thrive: A puppy who cannot feed effectively will fall behind its littermates in growth and energy levels.
• Nasal discharge or frequent sneezing: Chronic nasal irritation from inhaled food and liquid can cause ongoing discharge and sneezing.
• Aspiration pneumonia: This is a potentially life-threatening complication that occurs when food or liquid enters the lungs. Signs include labored breathing, lethargy, and fever.

If your puppy is showing any of these signs, time is of the essence. The earlier the condition is identified, the sooner a management plan can be put in place.

Breeds Most at Risk

While cleft palates can technically occur in any dog, certain breeds carry a well-documented higher risk due to their genetics and physical conformation.

• English Bulldogs and French Bulldogs: Brachycephalic breeds — those with flattened, shortened skulls — are consistently overrepresented in cleft palate cases. The genetic mutations that create their distinctive facial structure also appear to increase the likelihood of abnormal palate development. In Bulldogs specifically, the condition is believed to have a heritable component, meaning it can be passed down through breeding lines.

• Boston Terriers: Like Bulldogs, Boston Terriers are brachycephalic and share similar genetic predispositions. Their compressed facial anatomy places them at elevated risk for several oral and airway developmental abnormalities, including cleft palate and cleft lip.

• Beagles and Cocker Spaniels: These breeds have been identified in veterinary literature as having higher-than-average incidence of cleft palate, though the mechanism is less directly tied to facial conformation and more likely linked to hereditary genetic factors. Responsible breeders of these breeds are encouraged to screen breeding pairs with a history of the condition in their lineage.

If you have one of these breeds, make sure your veterinarian performs a thorough oral examination of every puppy in the litter shortly after birth — even if no obvious symptoms are present. Clefts located toward the back of the soft palate can be especially easy to overlook without a careful, deliberate inspection.

What You Can Do at Home

While a cleft palate ultimately requires veterinary intervention and, in most cases, surgical correction, there are important steps you can take at home to support your puppy’s health in the meantime.

If your puppy is unable to nurse effectively, your veterinarian may recommend tube feeding, which delivers nutrition directly to the stomach and bypasses the palate entirely. This method requires proper instruction from a professional, so never attempt it without guidance. Once you’ve been trained, however, it can be performed safely at home and is often necessary to keep affected puppies alive and growing during the weeks before surgery is an option.

Keep your puppy warm, clean, and closely monitored. Watch for any signs of respiratory distress, changes in breathing, or lethargy, and keep a log of their weight to track whether they are gaining appropriately. Weigh your puppy daily using a kitchen scale, as even small fluctuations can be meaningful at this age.

Keep all feeding equipment scrupulously clean to reduce the risk of bacterial infection. Avoid any feeding method that encourages the puppy to eat too quickly, as this increases the risk of aspiration.

When to See a Vet

Your puppy should be evaluated by a veterinarian as soon as a cleft palate is suspected — or ideally, as part of a thorough newborn exam for the entire litter. This is not a wait-and-see situation. Without proper management, puppies with cleft palates are at high risk of aspiration pneumonia, malnutrition, and failure to thrive, all of which can be fatal without prompt intervention.

Your vet will assess the size and location of the cleft, determine the most appropriate feeding strategy, and discuss the timeline for surgical repair. Most surgeons recommend waiting until the puppy is at least eight to twelve weeks old before performing corrective surgery, as the tissues need to be developed enough to hold sutures effectively. Some cases may require multiple procedures.

If your puppy develops labored breathing, refuses to eat, becomes lethargic, or shows signs of pneumonia at any point, seek emergency veterinary care immediately. These are urgent situations that cannot wait for a regular appointment.

How Pet Insurance Can Help

The cost of managing a cleft palate — from diagnostic exams and tube feeding supplies to anesthesia and surgical correction — can add up quickly, and it often arrives at a time when you least expect it. Having a pet insurance policy in place before issues arise means you can focus entirely on getting your puppy the care they need rather than worrying about the bill. Many plans cover congenital conditions and surgical procedures, making them well worth considering for any new puppy.
