Treating collapsing trachea in dogs can be a daunting prospect for owners. Tracheal collapse occurs when the windpipe becomes flattened and the airflow in and out of the lungs is obstructed.
Tracheal collapse in dogs is a condition characterized by incomplete formation or weakening of the cartilaginous rings of the trachea resulting in flattening of the trachea. It can be congenital or acquired, and extrathoracic or intrathoracic (inside or outside the thoracic cavity). Tracheal collapse is a dynamic condition.
In dogs, particularly miniature dogs and toy dogs, tracheomalacia, as well as bronchomalacia, [15] can lead to tracheal collapse, ...
