Plain-English summary
A group of 133 dogs with breathing problems underwent various tests to find out what was causing their symptoms. Many of these dogs showed signs of issues like coughing, which was linked to bronchial problems seen on CT scans and inflammation found in samples taken from their airways. Even when CT scans appeared normal, other tests like airway cytology and bronchoscopy revealed significant findings in most cases. This means that if your dog has respiratory issues, your vet may recommend multiple diagnostic tests to get a clearer picture of what’s happening, even if initial scans look fine.

Abstract
BACKGROUND: Several diagnostic techniques are used in dogs with signs of respiratory disease. The aims of the present study are to estimate the relative sensitivities and associations between the results of diagnostic tests in dogs with respiratory conditions. METHOD: A retrospective cross-sectional study of dogs referred for investigation of respiratory signs. Associations between clinical signs, thoracic CT findings, tracheobronchoscopic findings, cytology results and bacterial culture results were tested using binary logistic regression. RESULTS: One hundred and thirty-three dogs were included. Abnormalities were detected by cytology, tracheobronchoscopy, CT and bacterial culture in 91%, 88%, 80% and 25% cases, respectively. There were associations between cough and bronchial lesions on thoracic CT (odds ratio [OR] 2.6, 95% confidence interval [CI] 1.1-6.4, p = 0.037), and between cough and neutrophilic inflammation on cytology (OR 4.5, 95% CI 1.3-15.8, p = 0.020). Bronchial foreign body at bronchoscopy was associated with pulmonary consolidation on CT (OR 8.0, 95% CI 1.6-41.7, p = 0.013) and with positive bacterial culture (OR 10.9, 95% CI 2.1-57.0, p = 0.005). In dogs with normal thoracic CT, abnormalities were detected by cytology, tracheobronchoscopy and bacterial culture in 89%, 77% and 23% cases, respectively. CONCLUSION: Airway cytology and tracheobronchoscopy provided useful information for diagnosis in many dogs with respiratory signs that had a normal thoracic CT.
