Brachycephalic Airway Syndrome in Dogs: Vet-Approved Causes, Symptoms & Treatments (2025 Guide)🐶🩺

By Dr. Duncan Houston BVSc

As a veterinarian, I often encounter cases of Brachycephalic Airway Syndrome (BAS) in dogs, particularly in breeds with flat faces. Understanding this condition is crucial for early detection and effective treatment. This comprehensive guide aims to educate pet owners on the causes, symptoms, and treatment options for BAS in dogs.

🧬 What Is Brachycephalic Airway Syndrome?

Brachycephalic Airway Syndrome refers to a set of upper airway abnormalities commonly found in brachycephalic (short-nosed) dog breeds. These anatomical deformities can lead to breathing difficulties and other health issues. The primary components of BAS include:

• 👃 Stenotic Nares: Narrowed nostrils that restrict airflow.
• 👅 Elongated Soft Palate: Excessive soft palate tissue that obstructs the airway.
• 🗣️ Everted Laryngeal Saccules: Tissue inside the larynx that turns outward, further blocking airflow.

Additional abnormalities may include a hypoplastic (narrow) trachea and laryngeal collapse.

🐾 Breeds Commonly Affected

Brachycephalic breeds prone to BAS include:

•  Pugs
•  Bulldogs (English and French)
•  Boston Terriers
•  Shih Tzus
•  Boxers
•  Pekingese
•  Lhasa Apsos

⚠️ Symptoms of Brachycephalic Airway Syndrome

Signs of BAS can vary in severity and may include:

•  Noisy breathing or snoring
•  Difficulty breathing, especially during exercise or in hot weather
•  Excessive panting or fatigue
•  Gagging or retching
•  Cyanosis (bluish gums) indicating low oxygen levels
•  Collapse or fainting episodes

🩺 Diagnosing Brachycephalic Airway Syndrome

Diagnosis involves a combination of physical examination and diagnostic tests:

• Physical Examination: Assessing nostril size and breathing sounds.
• Sedated Oral Examination: Evaluating the soft palate and laryngeal structures.
• Imaging: X-rays or CT scans to assess the trachea and other structures.
• Laboratory Tests: Blood work to evaluate overall health.

💊 Treatment Options

Treatment depends on the severity of the condition:

Conservative Management

• Weight Management: Maintaining a healthy weight to reduce respiratory effort.
• Environmental Control: Avoiding heat and humidity.
• Stress Reduction: Minimizing excitement and strenuous activity.

Surgical Interventions

• Stenotic Nares Resection: Widening the nostrils to improve airflow.
• Soft Palate Resection: Trimming the elongated soft palate.
• Laryngeal Saccule Removal: Removing everted saccules obstructing the airway.

These procedures can often be performed simultaneously and have shown significant improvement in affected dogs.

🛡️ Preventing Brachycephalic Airway Syndrome

While BAS is congenital, certain measures can help manage and prevent exacerbation:

• Regular Veterinary Check-ups: Early detection and monitoring.
• Proper Nutrition: Maintaining an ideal body condition.
• Use of Harnesses: Avoiding pressure on the neck from collars.
• Climate Control: Keeping the dog in a cool, comfortable environment.
