Breed-related health problems cause widespread suffering in dogs and require systematic reform in breeding practices, registration requirements, and consumer behaviour.
Breed-related health problems represent some of the most severe and widespread welfare issues in companion animal care. Cavalier King Charles Spaniels bred with skulls too small for their brains develop chronic pain from fluid accumulation in the spine. Flat-faced dogs struggle to breathe throughout their lives. These conditions affect millions of dogs globally and are the direct consequence of breeding standards prioritising appearance over health. Systemic reform requires changes in breed standards, mandatory health testing, consumer education, and legislation restricting breeding of dogs with conformational conditions.
