An elongated soft palate is a congenital hereditary disorder that negatively affect dogs and cats' breathing and eating. A soft palate is considered elongated when it extends past the top of the epiglottis and/or past the middle of the tonsillar crypts.[1] The soft palate is made up of muscle and connective tissue located in the posterior portion on the roof of the mouth. The soft palate creates a barrier between the mouth (oral cavity) and nose (nasal cavity).[2] This continuation between the cavities makes it possible to chew and breathe at the same time. The soft palate only blocks the nasal cavity while swallowing. At rest the soft palate should only stretch caudally from the hard palate to the tip of the epiglottis leaving an opening between the nasal and oral cavities. When the soft palate is elongated, it partially blocks the throat thereby creating breathing and feeding-related issues. The elongation and other accompanying symptoms occur in breeds characterized with “smooshed faces” such as pugs, bulldogs, and Persian cats.[3] This condition is a congenital, meaning it is present when the animal is born. The “smooshed” characteristics is the result of a genetic mutation. The animal’s genetic code causes the bones in their skull to grow to a smaller size. Because the bones are smaller, muscles and other tissues that surround the bones of the skull are out of proportion. These animals are often referred to as brachycephalic, derived from the Greek words for “short” and “head”.[3] An elongated soft palate is a symptom of Brachycephalic Obstructive Airway Syndrome (BOAS) and is common in brachycephalic dog breeds and has been reported in brachycephalic cat breeds as well.[4] Some of the other BOAS related symptoms include stenotic nares, everted laryngeal saccules, and laryngeal collapse.[5]
