Cleft palates in French Bulldogs is a genetic disorder that is commonly seen in brachycephalic breeds.
It is characterized by an abnormal opening in the roof of the mouth.
During embryonic development, the two sides of the palate (roof of the mouth) fail to come together and fuse. This results in an opening between the nasal passages and the mouth.
Surgery to correct a cleft palate can be performed when puppies are 3-4 months old. It usually requires more than one operation to completely close the opening.
