Chronic bronchitis (CB) is an inflammatory airway disease, which in association with tracheobronchial collapse, is probably the most common chronic canine airway disorder.

Inflammation within airways causes a chronic cough and excessive mucusproduction. Chronic bronchial inflammation, regardless of cause, causes mucosal and airway wall thickening, mucus hypersecretion, and some degree of airway smooth muscle constriction.

The resulting signs are the defining features of canine CB and include cough and exercise intolerance. The primary treatment of CB is based entirely on controlling airway inflammation.
