Reforming breed standards to prioritise health over appearance is the most significant welfare intervention available for pedigree dogs.
Pedigree dog welfare is determined largely at the breeding stage, before puppies are sold. Breeds carrying heritable disease burdens — progressive retinal atrophy, hip dysplasia, degenerative myelopathy, brachycephalic syndrome — pass suffering to offspring through deliberate selection for looks over health. Health testing before breeding, using the conditions required for registration, eliminates most heritable diseases within 2-3 generations. The barrier is breeder behaviour and show standard incentives, not technical difficulty. Welfare reform requires reforming the incentive structures that reward unhealthy appearance.
