Dog Chronic Bronchitis: Welfare and Long-term Management

Canine chronic bronchitis is a progressive inflammatory airway disease causing persistent cough and reduced exercise tolerance, requiring lifelong management for welfare.

Key Facts

Chronic bronchitis is defined as persistent cough on most days for at least two consecutive months without identifiable cause
Small and toy breed dogs including West Highland white terriers and cocker spaniels are predisposed
Environmental triggers including cigarette smoke, dust, and air fresheners worsen clinical signs
Inhaled corticosteroids delivered via spacer devices are an effective and safe long-term treatment
Collapse of the trachea is commonly concurrent with chronic bronchitis in small breed dogs

Welfare Considerations

Chronic bronchitis causes persistent coughing that disrupts sleep, limits exercise, and reflects ongoing airway inflammation that reduces quality of life. Severely affected dogs hack repeatedly, often producing mucus or experiencing gagging. Chronic coughing fatigues respiratory muscles and can cause vomiting. Without management, the condition is progressive and increasingly disabling. Inhaled corticosteroids reduce airway inflammation effectively, often providing dramatic improvement in cough frequency and exercise tolerance. Environmental management — eliminating triggers including cigarette smoke, scented candles, and dusty bedding — is a critical and often underemphasised welfare intervention.

What You Can Do

Eliminate cigarette smoke, air fresheners, scented candles, and dusty substrates from environments shared with affected dogs
Work with a veterinarian to initiate inhaled corticosteroid therapy using an appropriately sized spacer device
Monitor exercise tolerance and cough frequency to assess treatment response
Investigate concurrent tracheal collapse in small breed dogs with chronic bronchitis and cough
