Features of BOAS
- Stenotic Nares (Narrow Nostrils):Narrowed nostrils makes it difficult for affected dogs to breathe in air. Surgery aims to widen the nares.
- Elongated Soft Palate:The soft palate, located at the back of the throat, extends further back in brachycephalic dogs due to their short skull length. This excess tissue can obstruct the airway and interfere with normal breathing. Surgical treatment involves taking away some of the excess tissue.
- Hypoplastic Trachea (Narrow Windpipe):The windpipe (trachea) may be narrower than usual, further impeding the flow of air into the lungs. Unfortunately surgery cannot treat this aspect of BOAS, instead treatment is more conservative.
- Everted Laryngeal Saccules:Small structures called laryngeal saccules, located in the voice box (larynx), may evert or protrude into the airway, causing additional airway obstruction. These can be dissected in surgery.
Symptoms of BOAS
Noisy Breathing: Brachycephalic dogs often exhibit loud and laboured breathing, especially during physical activity or in warm weather.
Exercise Intolerance: Difficulty breathing can lead to reduced stamina and intolerance to exercise.
Snoring and Snorting: These breeds may snore loudly or make snorting sounds, especially when sleeping.
Gagging or Vomiting: Due to the elongated soft palate, some dogs may gag, choke, or even vomit when eating or drinking.
Heat Intolerance: Brachycephalic dogs are more prone to overheating due to their compromised ability to cool themselves through panting.
Treatment and Management
- Surgical Intervention:In severe cases, surgical procedures may be recommended to address specific anatomical abnormalities.
- Weight Management:Maintaining a healthy weight is crucial to reduce the extra stress on the respiratory system. Many veterinary practices offer nurse clinics to support pet owners. Please contact your practice for advice.
- Environmental Considerations:Owners should be cautious about exposing brachycephalic dogs to high temperatures and strenuous exercise.
- Regular Veterinary Check-ups:Routine veterinary examinations are important for monitoring respiratory health and addressing any emerging issues promptly.
