Decades of selective breeding within closed pedigree populations has produced serious genetic health problems in many dog breeds, causing preventable suffering at population scale.
Pedigree dog breeding has prioritised aesthetic traits and breed type over health and welfare, producing breeds in which chronic suffering is normalised as characteristic appearance. Brachycephalic airway syndrome, hip dysplasia, syringomyelia, and progressive retinal atrophy are among the conditions that cause lifelong suffering in affected breeds. Reform requires change at multiple levels: kennel club standards, breed judge education, veterinary advice to prospective owners, and consumer demand shifts away from high-risk breeds. Genetic diversity restoration through outcrossing programmes offers a long-term structural solution.
