Chronic Bronchitis in Dogs: Long-term Airway Management

Canine chronic bronchitis causes persistent cough and progressive airway damage, requiring sustained management to maintain good respiratory welfare.

Key Facts

Chronic bronchitis is defined as daily cough for 2+ months without other identifiable cause
Irreversible airway changes develop over time, including mucus gland hypertrophy and airway remodeling
Bronchoalveolar lavage provides cytology and culture to characterize inflammation and identify infection
Prednisolone reduces airway inflammation and is the primary management tool
Inhaled fluticasone via AeroDawg spacer provides targeted airway treatment with fewer systemic effects
Bronchoscopy enables direct visualization of airway changes and sample collection
Secondary bacterial infection requires antibiotic treatment based on culture and sensitivity

Welfare Considerations

Chronic bronchitis causes persistent, distressing cough that disrupts sleep, exercise, and daily comfort. Dogs with poorly managed chronic bronchitis cough constantly, become exercise intolerant, and in severe cases develop hypoxia. The progressive nature of airway remodeling means that management must be sustained and optimized to slow disease progression. Inhaled corticosteroid therapy through aerosol chambers designed for dogs provides effective airway treatment with substantially fewer side effects than oral steroids, enabling safer long-term management. Weight management and avoiding respiratory irritants (smoke, dusty environments) are important adjuncts.

What You Can Do

Pursue diagnostic workup including chest radiography, airway lavage, and culture before committing to long-term management
Discuss inhaled corticosteroid therapy through a veterinary aerosol chamber to reduce systemic steroid side effects
Maintain healthy weight in dogs with chronic bronchitis - obesity worsens respiratory compromise
Avoid smoke, dusty environments, and respiratory irritants that exacerbate airway inflammation
Administer bronchodilators as prescribed for acute exacerbations
Monitor for secondary bacterial infection with increased cough, mucus production, or fever
Track cough frequency as an objective welfare metric showing treatment response
