Tracheal collapse is a degenerative and progressive disease characterized by anatomical and histological changes in the trachea, and is considered a common cause of upper airway obstruction in small animals. The diagnosis is made based on the animal's history, but it is only definitive through complementary exams, in which radiography is the most used. This study aimed to determine the occurrence of tracheal collapse in dogs through radiographic examination with external cervical tracheal compression, evaluating the degree of severity in symptomatic and asymptomatic animals, as well as determining the most affected breeds, sizes and ages. For this, a retrospective study was conducted in which clinical records and exams of 332 dogs that underwent radiographic method of tracheal compression in the veterinary hospital of the institution were analyzed in the period from January 1, 2010 to December 31, 2020. Data were collected regarding age, breed, size, gender and presence of characteristic clinical symptoms, in addition to verifying the reduction of the tracheal lumen and the corresponding degree of collapse. These data were tabulated and statistically analyzed using Tukey's test, Chi-square test for independence, and descriptive statistics. Through the interpretation of the results, there was a higher number of symptomatic animals, which were related to more severe degrees of tracheal collapse. Small dogs were the most affected, especially the breeds Poodle, Yorkshire terrier and Pinscher. Moreover, it was noted a higher incidence of this disease in adult to elderly dogs. By analyzing the results obtained with the compressive radiography, it was observed that it is a simple, safe and highly accurate diagnostic method for the diagnosis of tracheal collapse. Furthermore, the findings regarding the clinical predispositions and tendencies of the patients culminate with the aid of clinical thinking for the correct and early diagnosis of tracheal collapse.
