Brachycephalic obstructive airway syndrome (BOAS) is a disease of high prevalence in the three extreme brachycephalic breeds of dogs, the pug, bulldog and French bulldog. The lesion sites in these dogs are different, with nasal obstruction being more important in the French bulldog, laryngeal collapse and tracheal collapse in the pug and pharyngeal obstruction in the bulldog. At the moment, the most important predictive conformational factor of whether a dog will develop BOAS in the UK is the degree of nasal stenosis.The hypothesis of this study is wether the nasal stenosis is a reflection of excessive nasal cavity tissue, by looking at the amount of turbinate tissue present in the nasal cavity, the aberrant turbinates and the soft tissue proportion at the choanea, and also if there is a way that rhinoscopic measurements can be correlated with computed tomography (CT) measurements in dogs that undergo investigation for BOAS.
