Plain-English summary
A group of dogs with coughing issues underwent fluoroscopy, and it was found that 70% of them had cervical lung lobe herniation (CLLH), which is when part of the lung moves out of its normal position. Many of these dogs also showed signs of airway collapse. The study highlighted that while some dogs had a kink in their trachea during herniation, the length of time they had been coughing did not seem to affect the presence of CLLH. Understanding this condition can help veterinarians provide better care for dogs with persistent coughs and related breathing problems.

Abstract
This study aimed to determine the frequency of cervical lung lobe herniation (CLLH) in dogs evaluated fluoroscopically and to identify associated characteristics. Reports of diagnostic procedures and patient summaries from 2008 to 2010 were reviewed retrospectively. Signalment, body weight, duration of cough, presence of heart murmur and airway collapse, and radiographic findings were compared between dogs with and without CLLH. Of the 121 dogs that were examined, CLLH occurred in 85 (70%). The extra-thoracic trachea kinked during herniation in 33 (39%) dogs with CLLH. Collapse of the intra-thoracic trachea (assessed fluoroscopically or bronchoscopically) and collapse of major bronchi (assessed fluoroscopically) were strongly associated with CLLH. Although redundant dorsal tracheal membrane on radiographs was associated with CLLH, extra-thoracic tracheal collapse, assessed fluoroscopically or bronchoscopically, was not. No other associations were found. Cervical lung lobe herniation was present in most dogs evaluated during cough and was associated with intra-thoracic large airway collapse, but not duration of cough.
