Surgical correction of BOAS in brachycephalic dogs substantially improves quality of life but also reflects the welfare problems created by extreme selective breeding.
Dogs with moderate to severe BOAS live in a state of chronic respiratory compromise that limits their ability to exercise, thermoregulate, and sleep normally. The gradual onset means owners often normalize their dog's breathing difficulty as breed-typical rather than recognizing it as chronic suffering. Surgical correction provides meaningful welfare improvement, but corrected dogs still have structurally compromised airways compared to non-brachycephalic dogs - surgery ameliorates rather than eliminates the problem. The need for surgery to achieve basic respiratory function highlights the fundamental welfare failure of extreme brachycephalic breeding. The long-term solution is breeding reform toward functional conformation.
