Tracheal Collapse Management in Canine Health

Tracheal collapse is a progressive weakening of the cartilaginous rings in the canine trachea, most commonly affecting small and toy breeds. Clinical signs include chronic cough, respiratory distress, exercise intolerance and secondary airway inflammation. Management strategies span medical, environmental and interventional approaches. Medical therapy typically comprises weight reduction, cough suppressants, anti-inflammatories and bronchodilators. Environmental measures focus on minimising airway irritants and stress, often with harness use instead of collars. Interventional options include intraluminal stenting—most frequently with self-expanding nitinol devices—and novel extraluminal prostheses. Imaging modalities such as radiography, fluoroscopy and computed tomography guide diagnosis and severity grading, while emerging serum biomarkers offer objective measures of disease progression. Key challenges in long-term stent management include granulation tissue formation and device-related complications. A multidisciplinary approach tailored to individual patient severity has improved quality of life and prolonged survival in affected dogs globally.

The graph below shows the total number of articles in tracheal collapse management in canine health across all publications each year (not limited to Nature Index journals).

Technical terms

Tracheal collapse: A condition in which the cartilaginous rings of the trachea weaken, leading to airway narrowing and respiratory distress.

Fluoroscopy: A dynamic imaging technique using continuous X-rays to assess real-time tracheal collapse and airway motion.

Endoluminal stent: A self-expanding metallic device placed inside the tracheal lumen to mechanically support airway patency.

Matrix metalloproteinase-9 (MMP-9): An enzyme measurable in serum that reflects extracellular matrix remodelling and correlates with cough severity in tracheal collapse.
