Tracheal Collapse

RespiratoryCanineNew

Key Points

Tracheal collapse is a chronic, progressive airway disorder, characterised by weakening of the tracheal cartilage rings and dorsal tracheal membrane laxity, leading to narrowing of the lumen
It’s most common in toy / small breed dogs (Yorkshire Terriers, Pomeranians)
Collapse can occur in the cervical trachea, thoracic trachea or both
Clinical signs include a characteristic “goose-honk” cough that worsens with excitement, activity or pressure on the neck
Diagnosis requires imaging to visualise the collapse
Medical management is often effective for mild-moderate cases, but stenting should be considered in severe or refractory cases
Weight management and avoiding irritants or triggers are key for ongoing management

Differential Diagnoses

Chronic bronchitis
Myxomatous mitral valve disease (MMVD)
