Tracheal collapse in dogs is a respiratory condition that often coexists with other airway anomalies, such as bronchial collapse. These changes can have significant clinical repercussions, ranging from persistent cough to episodes of cyanosis and syncope, depending on the severity of the condition. Initial diagnosis is generally made through clinical evaluation and radiographs, but this approach may be insufficient as radiographs often underestimate the occurrence and severity of the collapse. Respiratory endoscopy, on the other hand, is considered the gold standard for confirming the diagnosis, allowing for precise visualization of the airways. However, the low frequency of respiratory endoscopies in dogs with respiratory symptoms limits the ability to obtain a conclusive diagnosis and proper staging of tracheal and bronchial collapse. This study aims to investigate the correlation between tracheal collapse and the presence of associated bronchial collapse, using respiratory endoscopy as the primary tool. The research seeks to demonstrate that tracheal collapse may be part of a broader picture of anatomical changes, and that a comprehensive diagnostic assessment is essential for effective treatment, aiming to improve the quality and life expectancy of affected patients.
