Selective breeding for extreme physical traits has created serious welfare problems in many popular dog breeds, causing lifetimes of discomfort and preventable suffering.
Breeding dogs for extreme conformational traits causes predictable, lifelong welfare problems. Brachycephalic dogs cannot breathe normally, sleep comfortably, or thermoregulate effectively. Many have undergone one or more corrective surgeries and still live with chronic discomfort. Syringomyelia in Cavaliers causes neurological pain throughout their lives. These welfare harms are not incidental — they are built into the breed standards. Welfare reform of breed standards, combined with consumer awareness and health testing requirements, is essential.
