Causes and Prevention of Bronchitis in Dogs

Causes of Canine Bronchitis

Bronchitis in dogs can be either an acute (sudden-onset) or a chronic (slow onset) condition. Acute canine bronchitis often comes at the tail end of a respiratory tract infection, which can be either bacterial or, more commonly, viral in nature. Other contributors to bronchitis in dogs can include physical or chemical inhaled atmospheric irritants, such as powdered feed products, chemical fumes, room deodorizers, irritating cleaning products and household dust, among others. However, a definitive cause of chronic bronchitis in canine companions has not yet been identified. This is a non-reversible, slowly progressive condition. When the sensitive lining of the respiratory tract becomes inflamed and irritated, it causes coughing and accompanying pathologic changes to the structure of the airways. They become thickened and narrowed, reducing the dog’s ability to inhale and exhale air properly and adversely affecting the normal transport and exchange of oxygen, carbon dioxide and other substances.

Prevention of Bronchitis

Keeping the household environment free from airborne fumes, chemicals and other irritants will help to prevent some cases of bronchitis in dogs. Otherwise, since the actual causes of chronic canine bronchitis are not well understood, it is not meaningful to speculate on what might be appropriate preventative measures.

Special Notes

Long-term bronchitis, which necessarily involves development of a chronic cough, can actually lead to broken ribs in especially severe cases.
