This time as part of our summer respiratory conditions awareness campaign, we are looking at Brachycephalic Obstructive Airway Syndrome, or simply BOAS.
This condition is a common issue among short-nosed, or brachycephalic, breeds such as French Bulldogs, Pugs, Shih Tzus, and Pekingese. BOAS can have a profound impact on their breathing often effecting sleep, excercise and digestive health.
Due to their compact facial structure, flat faced dogs have little room in their heads and nasal passages meaning there is reduced space in their airways when compared to other longer nosed breeds, meaning they struggle to breathe, even when resting.
Additional problems due to the unusual structure such as narrow nostrils, a thick, long soft palate, and a smaller voice box or windpipe can compound the issue.
If left untreated BOAS can lead to severe respiratory distress, particularly under stress, following exercise or warm temperatures. Due to the stress placed on the body due to the constant effort to breathe, gastrointestinal issues can develop in the form of regurgitation of food or froth, additionally behavioural issues due to discomfort and lack of sleep can develop over time.
Common signs to look out for include:
• Intense snoring
• Noisy breathing
• Effortful breathing - particularly in heat or following exercise
• Coughing and gagging - bringing up white froth/foam
• Fainting or collapse
• Sleep apnoea
• Behavioural changes - irritability and lethargy
