Selective breeding for extreme physical traits has created dogs that suffer significant health problems as a direct result of their appearance.
Breed-related health problems represent an ethical crisis in companion animal welfare — dogs are bred to appearance standards that guarantee suffering. A bulldog that cannot breathe normally, sleep comfortably or exercise adequately is experiencing chronic welfare compromise. The suffering is built into the dog before birth. Reform requires changing breed standards to prioritize health, education of buyers and support for breeders selecting for health over appearance extremes.
