Question 1

MEDIUM

A 4-year-old male neutered Labrador Retriever is presented for acute onset coughing and increased respiratory effort after vigorous play. Temperature is normal. Lung sounds are harsh with expiratory wheezes. Thoracic radiographs show a diffuse bronchial pattern without cardiomegaly or pleural effusion. Which diagnostic test is MOST appropriate to confirm the suspected underlying condition before initiating long-term therapy?

Diffuse bronchial pattern with wheezes and cough suggests inflammatory lower airway disease (chronic bronchitis/asthma-like disease). Bronchoalveolar lavage helps confirm airway inflammation type (eosinophilic vs neutrophilic), assess for infection, and guides targeted therapy before committing to chronic corticosteroids. Heartworm testing is reasonable in coughing dogs but does not confirm bronchitis and would not define airway inflammation/infection status.
