Cleft lip/palate and syndactyly (CLPS)

Cleft palate is a genetically inherited craniofacial birth defect affecting Nova Scotia Duck Tolling Retrievers, amongst other breeds. The defect is caused by a disruption in the secondary palate development, which is the bony structure separating the nose from the mouth, resulting in a hole or cleft in the palate. The cleft palate is accompanied by an uneven alignment of the upper and lower jaw, shorter mandibles, poorly developed or absent nasal septum and posteriorly placed tongue. The affected dogs show difficulties in feeding, with a high risk of aspiration pneumonia due to food entering the cleft. The disorder manifests itself during early stages of embryonic development.
