Canine Brachycephalic Obstructive Airway Syndrome (BOAS)

Canine Brachycephalic Obstructive Airway Syndrome (BOAS) is a condition that affects dogs, like French Bulldogs, Pugs, and Boston Terriers. BOAS is caused by a dog’s short muzzle and flat face, which results in narrowed airways. 

BOAS can lead to difficulty breathing and other respiratory issues. Symptoms of BOAS include snoring, snorting, gagging, and reverse sneezing. In severe cases, the dog will have difficulty exercising or even collapse due to lack of oxygen.

BOAS is a serious condition that can have a significant impact on the quality of life of affected dogs. It’s important to recognize the signs and symptoms of BOAS and get veterinary care if your dog has any signs of difficulty breathing. With proper treatment, affected dogs can lead happy and healthy lives.

Symptoms of Canine Brachycephalic Obstructive Airway Syndrome

The most common symptoms of BOAS are:

  • Snoring
  • Snorting
  • Gagging
  • Reverse sneezing

Other signs can include:

  • Difficulty breathing
  • Coughing
  • Wheezing
  • Exercise intolerance

Diagnosing Canine Brachycephalic Obstructive Airway Syndrome

To diagnose BOAS, a veterinarian will perform a physical examination and could recommend imaging tests such as X-rays or CT scans to view your dog’s airway. The vet can also conduct a sedated upper airway endoscopy to visualize their larynx, trachea, and soft palate. This procedure can help determine the severity of their problems and make it easier to create treatment options.

Stages of Canine Brachycephalic Obstructive Airway Syndrome

The stages of BOAS can vary depending on the severity of their condition. Generally, there are three stages:

Stage 1

Mild BOAS is characterized by snoring and snorting. The dog might also have difficulty breathing during exercise or when exposed to heat or humidity.

Stage 2

Moderate BOAS is associated with more pronounced symptoms such as gagging, reverse sneezing, and coughing. The dog might have difficulty breathing during exercise or when exposed to heat or humidity.

Stage 3

Severe BOAS is characterized by extreme difficulty breathing, which can lead to collapse due to lack of oxygen.

Treating Canine Brachycephalic Obstructive Airway Syndrome

Treating BOAS depends on the severity of their condition. Mild cases might not need any treatment, while more severe cases could need surgery to correct the airway obstruction. In some cases, medications such as bronchodilators and corticosteroids will be prescribed to help manage the symptoms.

It’s important to get veterinary care if your dog has any signs of difficulty breathing.

Preventing Canine Brachycephalic Obstructive Airway Syndrome

The best way to prevent BOAS is to avoid breeding dogs with short muzzles and flat faces. This will help reduce the prevalence of the condition in future generations.

It’s also important to keep your dog at a healthy weight, as obesity can worsen the symptoms of BOAS. 

It’s important to give your dog plenty of exercise and mental stimulation, as this can help reduce stress and anxiety which can exacerbate BOAS symptoms.

It’s important to monitor your dog’s environment for potential triggers such as heat or humidity. If possible, try to keep your dog in a cool and comfortable environment.
