Tracheal Collapse in Dogs
Progressive weakening of the tracheal cartilage, most common in small and toy breed dogs, causing a characteristic "goose-honking" cough.
Overview
Tracheal collapse involves progressive flattening of the cartilage rings supporting the trachea. It is most common in small and toy breeds and can be worsened by obesity, environmental irritants such as smoke, and pressure from a neck collar.
Clinical signs
- A dry, "goose-honking" cough, often triggered by excitement, exercise, collar pressure, or eating/drinking
- Exercise intolerance
- In severe cases, respiratory distress
Diagnosis
- Clinical history and the characteristic cough
- Radiographs, sometimes dynamic or fluoroscopic imaging since collapse can be intermittent
- Tracheoscopy to confirm and grade severity in select cases
Treatment
- Weight management and switching from a neck collar to a harness
- Cough suppressants and anti-inflammatory medication for symptomatic control
- Avoiding environmental irritants such as smoke
- Surgical options (extraluminal rings) or tracheal stenting for severe, refractory cases
Prognosis
Many dogs are well managed long-term with medical management and lifestyle changes. Severe, medication-refractory cases have a more guarded prognosis, though interventional options exist.

Frequently asked questions
Is tracheal collapse curable?
No, it is a progressive, chronic condition, but most dogs are managed successfully long-term with weight control, a harness, and medication as needed. Severe cases may benefit from surgical or stenting options.
Why does switching to a harness help?
A collar puts direct pressure on the trachea with every pull or tug, which can trigger coughing episodes and worsen irritation. A harness redistributes that pressure away from the airway.
