What is a wheeze characterized by in canine respiratory examinations?

• A. A soft gurgling sound
• B. A continuous musical tone
• C. A sharp cracking sound
• D. A low rumbling noise

Answer: (B)

Wheezing in canine respiratory examinations is characterized by a continuous musical tone. This sound typically occurs during expiration and can indicate narrowed airways, often due to conditions such as bronchoconstriction or inflammation within the respiratory tract. The musical quality arises from airflow passing through these narrowed passages, creating vibrations that produce the sound characteristic of wheezing. In contrast, other sounds listed do not describe wheezing. A soft gurgling sound may suggest fluid in the airways or a different condition like bronchial secretions. A sharp cracking sound is often associated with sudden openings of collapsed airways, while a low rumbling noise might indicate airflow through larger bronchi rather than the high-pitched tones typical of wheezing. Therefore, identifying wheezing specifically as a continuous musical tone helps in diagnosing potential underlying respiratory issues in canines.
