The trend toward extreme physical conformations in dog breeds such as flat-faced brachycephalic types causes lifelong suffering that requires urgent reform of breed standards and breeding practices.
Dogs bred for extreme physical characteristics live their entire lives with conditions that cause chronic discomfort and respiratory distress. A flat-faced dog that snores loudly is not charming; it is struggling to breathe adequately, particularly during exercise and sleep. Spinal deformities, eye conditions, and skin fold infections add to the welfare burden of breeds selected for appearance rather than health. The responsibility for this welfare crisis lies with breed clubs that maintained standards selecting for harmful conformations, the Kennel Club and its equivalents for allowing registration, and breeders and buyers who prioritised aesthetics over health.
