An eight-year-old male Siberian husky dog was evaluated for chronic coughing. Thoracic radiography revealed a diffuse bronchointerstitial pattern and dilatation of the left cranial and left caudal lobar bronchi. Bronchoscopy confirmed marked dilatation of the primary bronchi in the left cranial and caudal lung lobes. Bronchoalveolar lavage revealed septic, neutrophilic inflammation. A diagnosis of severe, focal, cylindrical bronchiectasis secondary to chronic bronchopneumonia was made. Initially, the dog responded well to antimicrobial therapy; however, clinical signs returned after cessation of therapy and generalised bronchiectasis developed after seven months. Chronic bacterial bronchopneumonia should be considered as a cause of focal and generalised bronchiectasis in dogs.
