Flat-faced dog breeds suffer widespread respiratory disease due to extreme selective breeding. BOAS is a preventable welfare crisis requiring both veterinary intervention and breeding reform.
BOAS represents a systematic breeding-induced welfare crisis affecting millions of dogs worldwide. Affected dogs cannot breathe normally throughout their lives — every breath requires more effort than it should. They cannot exercise normally, struggle to cool down in warm weather (a potentially fatal limitation), and may experience sleep apnoea disrupting rest. Many experience this chronic respiratory compromise as their normal baseline, never knowing what unrestricted breathing feels like. The popularity of these breeds has accelerated despite growing welfare evidence. The continued breeding of dogs with extreme conformations causing predictable, severe health problems represents a fundamental ethical failure of the breeding community and regulatory systems that permit it.
