Decades of selective breeding for extreme physical traits has left many dog breeds suffering from serious inherited health conditions. Reform efforts by kennel clubs, vets, and breeders are gaining ground but face significant resistance.
Breeding dogs for exaggerated physical features — extreme flat faces, excessive skin folds, tiny size, abnormally large heads — causes lifelong suffering. Brachycephalic dogs commonly require expensive surgery just to breathe adequately. Cavalier King Charles Spaniels are bred with skulls too small for their brains, causing chronic pain. Reform requires breed standards that prioritize health over appearance, mandatory health testing before breeding, and opening gene pools to allow diversity. Public demand for trendy breeds regardless of their health status drives continued harmful breeding practices.
