Surgical correction of breathing problems in flat-faced dogs has become routine, but it treats the consequences of harmful selective breeding rather than the underlying cause.
BOAS surgery improves quality of life for individual affected dogs, and the veterinary welfare case for performing it is strong. However, the existence of a surgical correction does not justify breeding dogs whose anatomy makes surgery necessary. A dog that breathes with audible effort at rest, cannot exercise normally, and sleeps poorly is suffering from a welfare deficit that persists even after corrective surgery improves airflow. The welfare-conscious approach to brachycephalic breeds requires not just treating affected individuals but changing breeding selection to produce anatomically healthier dogs. This requires pressure on breed standards, breeder health testing requirements, and consumer willingness to choose dogs with less extreme conformations even if they look less "cute."
