Brachycephalic Obstructive Airway Syndrome

BOAS is a breathing condition commonly found in flat-faced dog breeds. It involves issues like a long soft palate, narrow windpipe, protruding laryngeal saccules, and tight nostrils, making it challenging for these dogs to breathe comfortably.

BOAS primarily affects small to medium breeds like French Bulldogs, British Bulldogs, Pugs, Boston Terriers, and Pekinese. Breeding for shorter snouts has led to excessive soft tissue in a confined space, causing airway blockages.

Dogs with BOAS may exhibit symptoms like noisy breathing, difficulty exercising, overheating, and, in severe cases, collapsing or fainting due to insufficient oxygen reaching the brain.

Diagnosis is often based on breed and symptoms, but it may require a thorough examination under anaesthesia. Blood tests, X-rays, endoscopy, and CT scans may also be used for a comprehensive evaluation.

Treatment varies based on severity. In mild cases, weight management, preventing overheating, walking with a harness, and short-term medication may suffice. Severe cases may require surgical interventions like shortening the soft palate, widening nostrils, or removing laryngeal saccules.

Surgery aims to improve the dog’s breathing by addressing specific factors contributing to BOAS. While the extent of improvement varies, many dogs experience significant relief, enhancing their ability to breathe and exercise. Immediate recovery is usually good, with post-operative check-ups required.
