Many popular dog breeds suffer from heritable conditions caused by selective breeding for appearance. Reform of breed standards and breeding practices is essential to improve canine welfare.
Dog breed health represents a systemic welfare crisis created by over a century of selection for appearance traits at the expense of physical soundness. Conditions like syringomyelia in Cavaliers — where the skull is too small for the brain, causing lifelong neurological pain — are direct consequences of breed standards that prioritise a domed head shape. Hip dysplasia in large breeds causes progressive arthritis from early adulthood. The Norwegian court ruling that found certain breeding practices violated the Animal Welfare Act represents a watershed moment in breed health regulation. Reform requires coordinated action by kennel clubs, veterinary associations, breeders and buyers — including willingness to select less extreme phenotypes and prioritise health-tested bloodlines.
