Canine Tracheal Collapse: From Clinical Recognition to Definitive Management
Year: 2026
Type: article
Abstract: Canine tracheal collapse is a progressive, irreversible degenerative disease of the lower respiratory tract affecting primarily toy and miniature dog breeds. The condition is characterized by hypocellularity and loss of glycosaminoglycans within the C-shaped hyaline cartilaginous rings, leading to dorsoventral flattening of the tracheal lumen and laxity of the dorsal trachealis muscle. Clinical manifestations range from a mild, intermittent "goose-honk" cough to severe respiratory distress, cyanosis and syncope. Diagnosis relies on dynamic imaging techniques, including fluoroscopy and tracheobronchoscopy. Management encompasses conservative medical strategies—utilising antitussives, anti-inflammatory agents and weight management—alongside surgical interventions such as extraluminal ring prostheses or self-expanding intraluminal nitinol stents for refractory cases.
