Decades of selective breeding for extreme physical traits in dogs has created breeds with severe congenital health problems, and welfare reform requires both regulatory action and consumer choice change.
The breeding of dogs for extreme physical characteristics is one of the most ethically troubling areas of companion animal welfare because the suffering is built into the genetics before an animal is born. Brachycephalic dogs — those with shortened skulls — are physically incapable of breathing normally; many cannot exercise, sleep, or regulate their temperature without distress. The popularity of these breeds, driven by social media exposure of their flat-faced appeal, has dramatically increased production and therefore suffering. Reform requires action at multiple levels: veterinary education about the true health burden, consumer choice shifts away from extreme breeds, regulatory reform of breed standards, and legislative restrictions on breeding to extreme phenotypes.
