Understanding Brachycephalic Syndrome in Dogs

Shortnosed breeds, such as the Bulldog, Boston Terrier, Pug, and Pekingese, are among the most commonly affected by this syndrome.

Common physical features in dogs with this syndrome include narrow nostrils, an elongated soft palate, and an everted laryngeal saccule. Although these anomalies are present at birth, symptoms of difficulty breathing typically begin in early middle age.

The increased airway resistance caused by longstanding brachycephalic syndrome can lead to progressive respiratory distress. As the dog struggles to inhale, the immense negative pressure created pulls the larynx and trachea inward, making them fragile. Eventually, they may collapse, leading to severe airway obstruction, cyanosis (blue discoloration of the mucous membranes), and even death.

Signs of brachycephalic syndrome in dogs may include:

1. Noisy breathing

2. Intolerance to exercise

3. Cyanosis (blue gums due to oxygen deprivation)

4. Syncope (fainting)

Diagnosis of Brachycephalic Syndrome in Dogs

Diagnosis is usually based on the dog's breed and clinical symptoms. Possible diagnostic tests may include:

1. A thorough physical examination, including auscultation of the chest with a stethoscope to help rule out other causes of respiratory distress

2. Chest Xrays to check for heart or lung diseases

3. A visual examination of the nostrils to determine if there is a narrowing

4. (Under sedation) examination of the mouth and throat to diagnose an elongated soft palate or an everted laryngeal saccule

Treatment of Brachycephalic Syndrome in Dogs

Mild cases often do not require surgery and can be managed conservatively. While mild cases or sudden episodes of airway obstruction can be treated with medication (such as sedatives, oxygen, and hospitaladministered antiinflammatory steroids), there is a risk of progressive airway disease. Therefore, closely monitoring your dog's clinical symptoms is crucial.

Surgeries to correct the syndrome are relatively straightforward and offer better prognoses than attempting treatment after severe symptoms have developed. Potential surgeries (depending on the dog's specific anomalies) may include removing part of the nostrils to increase airflow, shortening the soft palate, and excising the everted laryngeal saccule.

AtHome Care

1. Keep a close watch for any worsening of your dog's clinical symptoms.

2. Prevent your dog from becoming overweight, as this can make breathing more difficult.

3. Avoid situations that could cause stress, such as exercising in hot, humid weather.

4. Avoid using a collar; instead, use a harness.

5. If your dog shows signs of respiratory distress or collapse, take it to the vet immediately.

6. After surgery, once your dog has recovered, special care may not be necessary. However, continue to monitor for any recurrence of clinical symptoms.
