• What did the research find?

The sensitivity of clinical examination for brachycephalic obstructive airway syndrome (BOAS) diagnosis was 56.7 per cent at rest, 70 per cent after a five-minute walk test and 93.3 per cent after a three-minute trot test. The sensitivity of laryngeal stridor as a predictor of laryngeal collapse was improved after exercise.

• How was it conducted?

Clinical examinations were performed on 44 client-owned brachycephalic dogs at rest and after five-minute walk and three-minute trot tests. A grade from 0 to 3, reflective of BOAS severity, was then assigned. Whole-body barometric plethysmography (WBBP) was used as a comparative, objective measure of disease severity. In the second part of the study, the degree of laryngeal collapse present in 57 dogs undergoing BOAS surgery was compared with …
