Brachycephalic syndrome, BOAS
What is brachycephalic syndrome? Symptoms of BOAS
Brachycephalic syndrome is a series of defects, such as malocclusion, an enlarged tongue, an elongated soft palate, narrowed nostrils and trachea, and swelling of the tissues around the larynx. Dogs with BOAS have difficulty breathing, which may be symptomatic of:
- loud breathing, wheezing,
- snoring during sleep, apnea,
- breathing through an open mouth, yawning,
- shortness of breath (especially after physical exertion), coughing,
- frequent sneezing,
- reflux, gagging, vomiting after meals,
- low exercise tolerance, rapid fatigue,
- intolerance to high temperatures,
- loss of consciousness, fainting,
- blue discoloration of the tongue and gums.
If you notice any worrying symptoms that may indicate that your dog is suffering from brachycephalic syndrome, you should visit your veterinarian immediately. Book an appointment now!

BOAS – diagnostic tests
- clinical examination,
- radiographic examination,
- endoscopic examination,
- anterior and posterior rhinoscopy, rhinomanometry,
- gastroendoscopy,
- oscillometry,
- blood tests (alkalosis in blood gas analysis).
Brachycephalic syndrome – treatment
BOAS treatment can be divided into conservative and surgical treatment. Surgery is usually required in moderate to severe cases. It may include nostril correction (rhinoplasty), tracheal correction, shortening of the soft palate (palatoplasty), removal of laryngeal pockets or tonsils.
Conservative treatment is recommended when symptoms are very mild. It involves the administration of anti-inflammatory drugs and bronchodilators, which facilitate airflow through the airways and aid breathing. An important part of conservative treatment is also preventing your dog from becoming overweight or obese, avoiding overheating and adjusting physical activity to your pet’s abilities. However, in most cases, surgery is necessary to restore your pet’s quality of life.
Untreated brachycephalic syndrome
One of the most dangerous consequences of untreated brachycephalic syndrome is hypoxia, caused by prolonged breathing disorders. Others include sleep disorders, overheating, heat stroke, fainting, loss of consciousness, chronic respiratory inflammation, permanent respiratory abnormalities, and cardiovascular problems. Unfortunately, the cute appearance and growing popularity of brachycephalic breeds do not serve them well. When taking care of such a dog, it is important to remember the health problems and conditions it will have to face throughout its life.
It is worth mentioning that the first symptoms of brachycephalic syndrome can appear in dogs as young as a few months old, and downplaying them increases the risk of complications.
