Responsible breeding practices including genetic health testing, conformation assessment, and breeding restriction policies dramatically reduce hereditary disease prevalence in dog populations.
Responsible breeding is one of the highest-leverage welfare interventions available in companion animal care because genetic decisions made today affect millions of dogs across future generations. The dramatic reduction in hip dysplasia rates achieved in some breeds through systematic testing and selective breeding demonstrates that hereditary disease prevalence can be meaningfully reduced over decades of commitment to evidence-based breeding programs. The challenge is that responsible breeding imposes costs on breeders — health testing, reduced breeding of popular but affected animals, and commitment to diversity over performance — that are not always matched by consumer willingness to pay premium prices. Policy tools including mandatory health testing requirements and breeding restrictions on affected animals can accelerate progress when voluntary adoption is insufficient.
