Selective breeding for extreme physical traits has created serious inherited health problems in many popular dog breeds. Welfare reform efforts aim to shift breeding standards toward health-focused criteria that reduce suffering across millions of dogs.
Inherited disease in pedigree dogs represents a large-scale, preventable welfare problem. Dogs with hip dysplasia experience pain throughout their adult lives that restricts exercise, disrupts sleep, and reduces quality of life substantially. Inherited eye diseases cause progressive vision loss that disorients and distresses affected animals. Cardiac conditions such as dilated cardiomyopathy in Dobermanns and mitral valve disease in Cavalier King Charles Spaniels significantly shorten lifespan. Many of these conditions are heavily influenced by breeding decisions and could be dramatically reduced through mandatory health testing, coefficient of inbreeding limits, and reformed breed standards. Consumer demand for health-tested dogs from responsible breeders drives market incentives for welfare improvement.
