Dog Allergic Bronchitis: Chronic Airway Disease in Dogs

Allergic bronchitis, also called canine chronic bronchitis, causes persistent airway inflammation and coughing that significantly diminishes quality of life for affected dogs when poorly managed.

Key Facts

Canine chronic bronchitis is defined as a cough persisting for more than 2 months not caused by other disease
The condition involves airway inflammation that causes mucus overproduction and bronchospasm
Allergens, air pollutants, cigarette smoke, and dust can trigger and worsen airway inflammation
Small and toy breeds including West Highland White Terriers are at elevated risk
Diagnosis involves chest X-rays, bronchoscopy, and ruling out other causes of cough
Treatment typically includes corticosteroids to reduce inflammation and bronchodilators
Untreated chronic bronchitis can progress to bronchiectasis, a permanent structural airway change

Welfare Considerations

Dogs with poorly controlled allergic bronchitis experience chronic coughing episodes that are distressing and physically exhausting. The sensation of being unable to breathe easily causes anxiety and restricts activity. Dogs may avoid exercise because exertion triggers coughing fits. Environmental exposures including secondhand smoke, scented candles, and air fresheners can trigger paroxysmal coughing that causes dogs visible distress. The condition is manageable with appropriate veterinary care, but owners may underestimate the degree of suffering their dog experiences because dogs cannot verbally communicate respiratory discomfort.

What You Can Do

If your dog has a persistent cough lasting more than a few weeks, seek veterinary diagnosis
Eliminate cigarette smoke, scented aerosols, and dust exposure from your dog's environment
Adhere closely to prescribed medication schedules for dogs with diagnosed bronchitis
Use air purifiers with HEPA filtration in rooms where your dog spends most time
Keep your dog at a healthy weight, as obesity worsens respiratory symptoms significantly
