Having a French Bulldog is a joy, but it’s important to be aware of any potential health issues that may arise.

One common issue is an underbite, which is when the lower jaw protrudes further than the upper jaw. While this can be a normal trait for French Bulldogs, it can also be a sign of an underlying health problem.

If your French Bulldog has an underbite, it’s important to have them checked out by a vet to make sure there are no other issues. An underbite can cause difficulty eating and speaking, as well as dental problems.

It can also lead to other health problems, such as respiratory issues and joint pain. If your French Bulldog does have an underbite, there are steps you can take to help manage the condition and improve its quality of life.

These include maintaining good oral hygiene, providing soft foods that are easier to chew, and avoiding activities that put a strain on the jaw. With proper care, your French Bulldog can still live a happy and healthy life with an underbite.

Causes of Underbites in French Bulldogs

The most common cause of an underbite in French Bulldogs is hereditary genetics.

Some dogs may be born with this condition, while others may develop it over time due to poor nutrition or dental hygiene.

Other causes of underbites include trauma to the face or jaw, certain diseases like arthritis or periodontal disease, and even poor breeding practices.

Symptoms of an Underbite in French Bulldogs

An underbite can be easily identified by looking at your dog’s mouth from above.

The lower jaw should not protrude out past the upper jaw when viewed from this angle.

If it does, then your dog likely has an underbite.

Other signs include difficulty eating or chewing food due to misaligned teeth or jaws, drooling more than usual, and bad breath due to food particles being trapped between teeth due to overcrowding or misalignment.

Treatment Options for French Bulldogs with an Underbite

If your Frenchie has been diagnosed with an underbite, you have several treatment options depending on how severe the condition is.

Mild cases may be able to be managed through diet changes and regular dental hygiene, while more severe cases may require surgery to correct the misalignment of their jaws.

Your veterinarian will be able to help you determine which option is best for your pup’s individual needs.

Prevention of an Underbite in French Bulldogs


The French Bulldog breed is predisposed to underbites due to their short snouts and wide jaws. This genetic predisposition means that the breed is more likely to develop an underbite than other breeds.

To prevent an underbite, it is important to understand the genetics of the breed and work with a reputable breeder who can provide information on the lineage of the puppy.

It is also important to be aware of any health issues that may be present in the puppy’s parents or grandparents, as these can increase the chances of an underbite developing.


Diet plays a major role in preventing an underbite in French Bulldogs.

An appropriate diet should include high-quality, nutrient-dense foods that are specifically formulated for this breed. Feeding your French Bulldog a balanced diet will help ensure that its teeth and jaw stay strong and healthy, reducing the chances of an underbite developing.

Additionally, avoiding treats with hard or crunchy textures can help prevent an underbite from forming by keeping their teeth and jaw from becoming misaligned.

Oral Hygiene

Regular oral hygiene is essential for preventing an underbite in French Bulldogs.

Brushing their teeth at least once a day with a soft-bristled toothbrush will help keep their teeth clean and free from plaque buildup, which can cause misalignment of the jaw and teeth.

Additionally, regular dental checkups with a veterinarian are important for identifying any potential issues before they become serious problems.


Exercise is also important for preventing an underbite in French Bulldogs. Regular exercise helps keep their muscles strong and flexible, which can help prevent misalignment of the jaw and teeth over time.

Additionally, providing toys that require chewing can help strengthen their jaw muscles and keep them from becoming too weak or misaligned due to lack of use.

Professional Care

Finally, professional care is essential for preventing an underbite in French Bulldogs. Visiting a veterinarian regularly for checkups and dental cleanings will help identify any potential issues before they become serious problems.

Additionally, visiting an experienced dog trainer can help teach your French Bulldog proper behaviors that will reduce the chances of them developing an underbite due to bad habits such as excessive chewing or biting on hard objects.

Pros and Cons of Having a French Bulldog With An Underbite

Owning a Frenchie with an underbite comes with its own set of pros and cons, depending on how severe his/her case may be.

On one hand, having a mild case means you don’t have to worry about any special treatments beyond regular dental care.

However, if your pup has a more severe case, then surgery might be necessary, which could come at quite a hefty price tag.

Additionally, if left untreated, these conditions could lead to further health complications down the line, so owners must take proactive steps toward prevention and treatment if needed.
