Canine Brachycephalic Obstructive Airway Syndrome (BOAS)

Canine Brachycephalic Obstructive Airway Syndrome

Canine Brachycephalic Obstructive Airway Syndrome (BOAS) is a condition that affects dogs, like the French Bulldog, Pug, and Boston Terrier. 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 may 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 seek veterinary care if your dog is showing 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 in dogs are:

  • Snoring
  • Snorting
  • Gagging
  • Reverse sneezing

Other signs may 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 the 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 the condition. Generally, there are three stages: 

Stage 1

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

Stage 2

Moderate BOAS is characterized by more pronounced symptoms such as gagging, reverse sneezing, and coughing. The dog may also 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

Treatment for BOAS in dogs depends on the severity of the condition. Mild cases may not require any treatment, while more severe cases may require surgery to correct the airway obstruction. In some cases, medications such as bronchodilators and corticosteroids may be prescribed to help manage the symptoms.

It is important to seek veterinary care if your dog is showing any signs of difficulty breathing.

Preventing Canine Brachycephalic Obstructive Airway Syndrome

The best way to prevent BOAS in dogs 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. 

Additionally, 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.

Finally, it is 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.
