Medical Details

Transmission

This is a chronic inflammatory disease, not an infection. It is not contagious to other animals or humans.

Progression & Stages

The disease begins with a mild dry cough that progressively worsens over months or years. In late stages, it can lead to exercise intolerance and tracheal sensitivity. It can predispose to respiratory infections.

Diagnosis

Diagnosis is one of exclusion. Vet rule out heart disease, parasites, and infection. Chest X-rays typically show a "bronchial" pattern (donuts/tramlines). Bronchoscopy is the gold standard.

Treatment Protocols

Management involves weight loss (to reduce oxygen demand), using a harness instead of a collar, and potentially inhaled or oral corticosteroids to reduce inflammation. Cough suppressants may help comfort.

Prevention

There is no specific prevention, but maintaining a healthy weight and avoiding respiratory irritants (smoke, perfume) can help manage risk.

Prognosis

The condition is irreversible and progressive but can be managed successfully for years, allowing for a good quality of life.
