Plain-English summary
A group of elderly small breed dogs with bronchomalacia, a condition that causes chronic coughing and breathing problems, were examined for their oxygen levels. Most of these dogs showed low oxygen levels but normal carbon dioxide levels, indicating difficulty in getting enough oxygen. Imaging tests revealed abnormal lung patterns in all the dogs, confirming the diagnosis. The study suggests that blood gas analysis can help identify breathing issues related to bronchomalacia.

Abstract
Canine bronchomalacia (CBM) is a structural airway disease leading to chronic cough and intermittent respiratory distress, primarily affecting elderly dogs of small breeds. Results of blood gas analysis have been reported in dogs with several diseases, but not yet in those with CBM. Eleven dogs with CBM were recruited in this study. Most dogs presented with mild hypoxemia and normocapnia, and all with increased alveolar-arterial difference for O2 (A-aDO2). In computed tomography, abnormal lung patterns, such as atelectasis and parenchymal band, were detected in all dogs, consistent with the regions affected by CBM. We conclude that CBM causes abnormal lung patterns and results in impaired oxygenation. Blood gas analysis is a useful tool for detecting mild pulmonary lesions and concurrent CBM.
