Plain-English summary
A group of 222 dogs suspected of having tracheal collapse (TC) were examined, and 199 of them were diagnosed with the condition. Interestingly, many dogs with TC did not show a history of coughing, which means that a thorough physical exam and imaging tests are important for diagnosis. However, cervical lung herniation (CLH), which can occur alongside TC, was found to be linked to a history of coughing. This means that if your dog has a persistent cough, it might be worth discussing the possibility of CLH with your veterinarian, especially if they also show signs of breathing difficulties.

Abstract
This retrospective study included 222 dogs suspected to have tracheal collapse (TC) and examined between 1 January 2012 and 31 December 2015. Fluoroscopic and radiographic images and medical records were evaluated to investigate the fluoroscopic characteristics of TC and cervical lung herniation (CLH), and to determine their relationships to various influencing. Grade of TC, existence of tracheal kinking, location of CLH (right or left side), and grade of CLH were evaluated fluoroscopically. One hundred ninety-nine dogs (89.6%) were diagnosed with TC. Presence of TC was not associated with the patients' cough history; however, CLH was positively correlated with cough history (odds ratio [OR], 2.896; 95% confidence interval [CI], 1.556 to 5.390) and was affected by tracheal kinking (OR, 3.841; 95% CI, 1.884 to 7.831). Chronic cough was not related with CLH. Since TC can be observed in patients without a history of cough, presence of TC should be ruled out by using physical examination and diagnostic imaging. Although CLH is associated with a history of cough, it is a common appearance in dogs, and transient coughing can elicit CLH in patients without a history of cough.
