Brachycephalic dog breeds including bulldogs, pugs, and French bulldogs suffer from serious structural health problems caused by selective breeding for extreme facial features.
Brachycephalic dogs are among the most significant examples of welfare harm caused by human aesthetic preferences in selective breeding. Animals bred for extreme flat-faced conformations often spend their entire lives with chronically compromised breathing, exercise intolerance, disrupted sleep, and high risk of heat stroke. Yet these features are precisely what drive consumer demand. Veterinary organizations worldwide have called for breeding reform, advertising restrictions, and health testing requirements. The welfare case for regulation is compelling — individual animals suffer chronically from birth to death as a direct result of deliberate breeding choices. Reform requires simultaneous action from kennel clubs, breeders, advertisers, and buyers.
