What is BUAS in Dogs?

Brachycephalic Upper Airway Syndrome (BUAS) is a respiratory condition commonly seen in breeds with short, flat faces—such as Bulldogs, Pugs, Boston Terriers, and French Bulldogs. These breeds have unique skull shapes that can cause structural obstructions in the upper airway, making it difficult for them to breathe normally.

Dogs with BUAS often experience one or more anatomical issues, including narrowed nostrils (stenotic nares), an elongated soft palate, everted laryngeal saccules, and, in some cases, a narrowed trachea. These obstructions can cause noisy breathing, limited exercise tolerance, and even life-threatening respiratory distress if left untreated.

Common Symptoms of BUAS

Recognizing the early signs of BUAS is key to ensuring your dog receives the right care.

Common symptoms include:

• Loud or Noisy Breathing: Especially noticeable during exercise, excitement, or heat.

• Snoring or Snorting: These sounds may occur even when your dog is awake.

• Exercise Intolerance: Affected dogs tire easily or may struggle to keep up on walks.

• Struggling to Breathe: Dogs may exhibit increased effort when inhaling, especially during physical activity.

• Regurgitation or Vomiting: Airway obstruction can lead to swallowing difficulties and gastrointestinal upset.

• Change in Posture: Some dogs may extend their necks or sleep in unusual positions in an effort to breathe more comfortably.

If your dog exhibits any of these signs, it’s important to consult your veterinarian. Early intervention can make a significant difference in comfort, safety, and long-term quality of life.

How Surgery Can Help

BUAS surgery is designed to remove or correct the physical obstructions that make breathing difficult. Depending on your dog’s condition, one or more surgical procedures may be recommended.

• Stenotic Nares Correction: Widens the nostrils to improve airflow through the nose.

• Soft Palate Resection: Shortens the elongated soft palate to prevent airway blockage.

• Laryngeal Saccule Removal: Removes tissue that has become everted and is obstructing airflow.

• Advanced Airway Procedures: In rare or severe cases, a tracheostomy or other specialized surgery may be necessary to restore safe breathing.
