Which sound would be expected from a canine experiencing a respiratory issue?

In the context of respiratory issues in canines, nasal stridor is a common sound associated with airway obstruction or respiratory distress. Stridor is characterized by a high-pitched, wheezing sound created by turbulent airflow in narrowed airways. It often indicates problems such as laryngeal paralysis, tracheal collapse, or obstruction in the upper airways, all of which are critical conditions that require veterinary attention.

The other sounds listed do not typically relate to respiratory issues in dogs. Borborygmi refers to the rumbling sounds produced by the movement of fluid and gas in the gastrointestinal tract, indicating digestive activity rather than respiratory problems. Clicks can result from various non-respiratory conditions, such as joint movement or dental issues, and flatulence is a symptom of gastrointestinal gas release, not related to airway or lung function. Therefore, the expectation of nasal stridor occurring in a dog experiencing respiratory issues makes it the appropriate choice in this scenario.
