Abstract
The trachea has the important function of connecting the upper and lower respiratory systems, it has a flexible tubular structure, containing cartilaginous rings along its entire length. Imaging technology makes it possible to study this organ, and can then diagnose dysfunctions and natural thinning of its diameter, as occurs with the Shih-tzu breed (brachycephalic). The study with brachycephalic breeds aims to define racial characteristics in relation to the aforementioned organ through radiographic examination. Image analysis was performed with 24 Shih-tzus of both sexes, 1 to 9 years old. In the study, 41.67% of the dogs of both sexes obtained values within the references studied; 25% of the animals obtained values equal and above 0.2 cm, fitting the parameters for non-brachycephalic dogs, and 33.33% were below 0.16, fitting the bulldog breed. Further studies are needed for a better clinical understanding of the particularities of this breed.
