Selective breeding for extreme physical traits in pets — flat faces, dwarfed limbs, exaggerated coats — causes measurable, lifelong suffering in millions of animals.
Breeding animals for features that cause structural suffering is a significant welfare crisis hidden in plain sight. Brachycephalic obstructive airway syndrome (BOAS) causes lifelong breathing difficulty that owners often misread as normal. Surgically correctable in some cases, the underlying genetic cause persists through continued breeding. Regulatory reform — breed standards that prioritize health, not appearance — is the most systematic intervention.
