Reform of breed standards to prioritise health over extreme physical traits is urgently needed to improve the welfare of millions of pedigree dogs.
Breeding dogs for extreme physical traits prioritised by show standards or fashion causes heritable welfare problems that affect millions of individual dogs. Brachycephalic breeds experience lifelong respiratory distress, exercise intolerance, and sleep apnoea. Reform requires changes to breed standards, adoption of mandatory health testing, and shifts in consumer demand toward healthier breed types.
