Understanding Brachycephalic Airway Disease in Dogs


Brachycephalic Airway Disease (BOAS) is commonly found in dogs with short, pushed-in faces, such as Bulldogs, Pugs, and French Bulldogs. This disease affects their respiratory system and can lead to significant health issues if left untreated. Pet Insurance Australia explores BOAS, its causes, symptoms, treatment options, and more to help you better understand and care for your furry companions.

What is Brachycephalic Airway Disease (BOAS)?

Brachycephalic Airway Disease (BOAS) is a syndrome characterised by a combination of upper airway abnormalities, including stenotic nares (narrowed nostrils), elongated soft palate, everted laryngeal saccules (protrusion of tissue into the larynx), and hypoplastic trachea (narrowed windpipe). These anatomical abnormalities restrict airflow, making breathing difficult for affected dogs, especially during physical activity or in hot weather.

Causes of Brachycephalic Airway Disease

The primary cause of BOAS is the physical conformation of brachycephalic dog breeds. Their short, flattened faces result in compressed airways and restricted breathing passages, predisposing them to respiratory issues. Other contributing factors may include obesity, excessive heat, exercise intolerance, and environmental pollutants.

Top Symptoms of Brachycephalic Airway Disease in Dogs

  • Noisy or difficult breathing, especially during exercise or excitement
  • Snorting, snoring, or wheezing sounds
  • Difficulty breathing, especially when sleeping or resting
  • Exercise intolerance or reluctance to engage in physical activity
  • Cyanosis (bluish discolouration of the gums or tongue) during periods of exertion

 How Do You Treat Brachycephalic Obstructive Airway Syndrome?

Treatment for BOAS typically involves a combination of medical management and surgical intervention. Medical management may include:

  • Weight management.
  • Environmental modifications (such as keeping the dog in cool, well-ventilated areas).
  • Medications to reduce inflammation or respiratory distress.
  • Surgical intervention, such as soft palate resection or nares widening surgery, may be necessary to alleviate airway obstruction and improve breathing.

 

How Long Does It Take to Recover from BOAS Surgery?

Recovery from BOAS surgery varies depending on the extent of the procedure and the individual dog’s health and condition. Dogs undergoing surgical intervention for BOAS may require several weeks to recover fully. During this time, they may need restricted activity and close monitoring for complications.

Common Dog Breeds Affected by BOAS & Why?

Brachycephalic Airway Disease primarily affects dog breeds with short, flat faces, including Boxers, Pugs, French Bulldogs, Boston Terriers, and British Bulldog/English Bulldogs. These squishy-faced breeds are predisposed to BOAS due to their anatomical conformation, which includes narrowed nostrils, elongated soft palates, and other upper airway abnormalities that impede airflow.

Is Brachycephalic Airway Syndrome Fatal?

While Brachycephalic Airway Disease itself may not be fatal, severe cases can lead to respiratory distress, heat stroke, or other complications that may be life-threatening if left untreated. Prompt diagnosis and appropriate management are essential for optimising affected dogs’ quality of life and longevity.

Can Brachycephalic Airway Disease in Dogs Be Cured?

Brachycephalic Airway Disease cannot be cured, but it can be managed effectively with a combination of medical and surgical interventions. By addressing underlying airway abnormalities and implementing lifestyle modifications, such as weight management and environmental adjustments, the symptoms of BOAS can be alleviated, and the progression of the disease can be slowed. This reassurance instills a sense of hope and optimism in the face of this condition.

What is the Lifespan of Chronic Brachycephalic?

The lifespan of a dog with chronic Brachycephalic Airway Disease may be reduced compared to dogs without respiratory issues. However, with proper management and care, many affected dogs can lead happy, comfortable lives well into their senior years.

Does BOAS Get Worse with Age?

Early intervention is crucial in Brachycephalic Airway Disease. As the dog’s airway abnormalities progress or as the dog ages, the symptoms may worsen. However, proactive management strategies and timely veterinary care can help slow the progression of the disease, improve the dog’s quality of life, and prevent potentially life-threatening complications.

 

How Much Does Brachycephalic Airway Syndrome Surgery Cost in Australia?

The cost of BOAS surgery in Australia can vary depending on the specific procedure performed, the veterinary clinic or specialist performing the surgery, the dog’s overall health, and any additional services or medications required. Generally, surgical treatment for BOAS can range from several hundred to several thousand dollars.

 

Prevention Tips Brachycephalic Airway Disease in Dogs

While Brachycephalic Airway Disease cannot always be prevented, there are steps that owners of brachycephalic breeds can take to reduce the risk and severity of respiratory issues:

  • Choose a reputable breeder who prioritises health and sound breeding practices.
  • Maintain a healthy weight for your dog through proper diet and exercise.
  • Avoid strenuous exercise, especially in hot or humid weather.
  • Provide your dog with a cool, well-ventilated environment, especially during warmer months.
  • Monitor your dog closely for signs of respiratory distress and seek veterinary care if symptoms arise.

 

Is Brachycephalic Syndrome Hereditary?

Brachycephalic Airway Disease is primarily caused by the physical conformation of brachycephalic dog breeds, which is influenced by genetics. While the syndrome itself is not hereditary, the predisposition to BOAS is passed down through generations of selectively bred brachycephalic dog breeds.

How Do You Know If Your Dog Needs BOAS Surgery?

If your dog shows signs of Brachycephalic Airway Disease, such as noisy or laboured breathing, difficulty exercising, or cyanosis (a bluish to purplish tint of the skin or gums caused by insufficient oxygenation), it’s crucial to seek veterinary evaluation promptly. Early detection empowers you to take proactive steps in your pet’s health. Your veterinarian can perform diagnostic tests, such as physical examination, x-rays, or airway endoscopy, to assess the severity of your dog’s condition and recommend appropriate treatment options, which may include surgery.

Can Brachycephalic Syndrome Be Prevented?

While Brachycephalic Airway Disease cannot always be prevented, responsible breeding practices play a significant role in reducing the risk and severity of respiratory issues in brachycephalic dog breeds. By prioritising health and well-being, you demonstrate your care and responsibility towards your beloved companions.

How to Choose the Right Time for BOAS Surgery

Determining the ideal age for Brachycephalic Obstructive Airway Syndrome (BOAS) surgery depends on various factors, including the severity of the dog’s symptoms, overall health, and breed. While there is no one-size-fits-all answer, veterinarians typically recommend waiting until the dog has reached skeletal maturity before considering surgical intervention for BOAS. This usually occurs around 12 to 18 months of age for most brachycephalic breeds.

 

Do All Brachycephalic Breeds Require BOAS Surgery?

While Brachycephalic Airway Disease is more prevalent in certain breeds with extreme facial features, such as Bulldogs, Pugs, and French Bulldogs, not all brachycephalic dogs will require surgery. The decision to undergo BOAS surgery depends on the severity of the dog’s symptoms and the impact on their quality of life. Some brachycephalic dogs may manage well with lifestyle modifications and medical management alone, while others may benefit from surgical intervention to improve their breathing and overall well-being.

 

How Do Vets Diagnose & Test for BOAS?

Veterinarians use a combination of diagnostic tests to assess and diagnose Brachycephalic Airway Syndrome in dogs:

  1. Physical Examination: A thorough physical examination allows the veterinarian to assess the dog’s airway anatomy, including the presence of stenotic nares (closed or narrow nostrils) , elongated soft palate, and other upper airway abnormalities.
  1. X-rays: Radiographs (x-rays) of the chest may be taken to evaluate the size and shape of the dog’s airway structures, such as the trachea and larynx.
  2. Endoscopy: Airway endoscopy involves inserting a flexible camera (endoscope) into the dog’s airway to visualise and assess abnormalities, such as narrowed nostrils, elongated soft palate, or everted laryngeal saccules.
  3. Respiratory Function Tests: Pulmonary function tests, such as arterial blood gas analysis or respiratory airflow measurements, may be performed to evaluate the dog’s respiratory function and assess the severity of airway obstruction.

Brachycephalic Airway Disease is a severe health concern for many brachycephalic dog breeds, but with early detection, proper management, and veterinary care, affected dogs can lead happy, comfortable lives. By understanding the causes, symptoms, treatment options, and prevention strategies for BOAS.

How to Help Brachycephalic Dogs
