Tracheal Collapse
Tracheal collapse is a progressive weakening of the tracheal cartilage rings, leading to airway obstruction and chronic cough, especially in toy breeds.
Detailed Description
The trachea loses rigidity due to degeneration of cartilage, causing it to flatten and partially obstruct airflow. This results in a characteristic 'goose-honk' cough, exercise intolerance, and respiratory distress. Severity can range from mild to life-threatening.
Common Symptoms
- Honking cough
- Worsened by excitement or pressure on neck
- Exercise intolerance
- Respiratory distress
Management Options
- Weight management
- Cough suppressants
- Bronchodilators
- Anti-inflammatories
- Harness instead of collar
- Surgical intervention (tracheal stenting)
