Brachycephalic dogs including Bulldogs, French Bulldogs, and Pugs suffer from chronic respiratory compromise caused by extreme skull conformation that is a direct result of breeding selection.
Brachycephalic syndrome represents a welfare crisis created by human breeding preferences. Dogs that struggle to breathe, sleep, or exercise without distress are being produced in record numbers to satisfy consumer demand for flat-faced appearances. Every breath for a severely affected dog involves effort and partial obstruction. Surgery helps but cannot restore normal function. The most effective intervention is breeding reform — selecting away from extreme conformations through breed standards revision, grading schemes that assess breathing capacity before breeding, and consumer education about the welfare costs of extreme brachycephalic conformation.
