More than half of brachycephalic (flat faced) dogs suffer from a potentially life-threatening condition known as Brachycephalic Obstructive Airway Syndrome (BOAS).
BOAS significantly increases the risk of heatstroke during warmer weather.
In summer 2023, SASH saw 25 critical cases involving brachycephalic dogs during a single hot weekend. Sadly, some of these dogs passed away as a result of their condition.
Surgical correction of BOAS significantly improves the outcome in these critical cases and gives these dogs a new lease on life.
On a single hot weekend in summer 2023, SASH saw 25 critical cases involving brachycephalic dogs.
At-risk breeds
Brachycephalic dogs have skull bones that are shortened in length which give the face, snout and nose, a pushed-in appearance. The diagram below shows breeds that are all considered “at risk” for BOAS.
What causes BOAS?
The flat-face and shortened skull results in abnormal anatomy of the upper airways. Brachycephalic dogs typically have narrowed nostrils, overly-long soft palates and excessive tissue around the larynx (in the throat) and within the nasal cavity. The trachea (windpipe) can also be very narrow. They’re also at higher risk of internal hernias which can cause regurgitation.
As a result of their anatomy and narrowed airways, affected dogs can have breathing and digestive difficulties that negatively impact their daily life.
Signs of BOAS
BOAS physically obstructs airflow and causes problems with breathing. Dogs suffering from BOAS may exhibit the following:
- Snoring & trouble sleeping
- Loud or difficult breathing
- Reduced ability to exercise
- Poor tolerance to heat
- Digestive problems, such as regurgitation
Diagnosing BOAS
Your surgeon will gather a great deal of information about your pet by asking you for a detailed clinical history. They may ask questions about how your dog exercises, what noises they make at rest, during exercise and when asleep, and whether they have any digestive issues. Your surgeon will then conduct a physical examination and carefully listen to your dog’s airways with their stethoscope. Often this is all that is required for your surgeon to confidently recommend surgery for your pet.
BOAS Surgery
With the rising popularity of brachycephalic breeds, surgery to treat BOAS is very common. The aim of surgery is to remove excessive tissue to improve the anatomical issues that restrict airflow. Typically, this involves widening the nostrils, shortening the soft palate, and removing excessive tissue around the voice box and back of the throat.
Although BOAS surgery is regularly performed at SASH, like all procedures, it carries a degree of risk. SASH takes all necessary precautions by being one of the only centres in NSW to provide support from both specialist Anaesthesia and specialist Critical Care teams. They work closely with the highly experienced Surgery team to maximise positive outcomes from these surgeries.
After BOAS surgery, it is common for patients to remain overnight for careful, 24/7 monitoring in the ICU, under the care of the specialist Critical Care team.
Outcomes from BOAS surgery
Although we cannot “cure” BOAS, surgery will usually provide a significant improvement to airflow which enhances your dog’s quality of life. Generally, owners will notice reduced noises associated with breathing and a more active and playful dog. They may also see improvement in any pre-existing digestive issues.
With the lead up to summer, BOAS surgery can save lives by reducing the risk and severity of potentially deadly heatstroke. Dogs will often gain the most benefit from BOAS surgery when it is performed early in life, typically between the ages of 6 months and 2 years.
If your dog suffers from snoring, loud breathing, or exercise intolerance, it is recommended for them to be assessed by a veterinarian for BOAS. If BOAS has been determined to be a health or welfare concern, corrective surgery prior to hot weather may be beneficial to reduce to risk of heat stroke and other temperature-related complications
