Breed standards that prioritize exaggerated physical features over health and functionality have produced severe chronic welfare problems in many popular companion dog breeds.
Breed-related welfare problems represent one of the most ethically challenging areas in companion animal welfare - millions of dogs live with chronic pain and disability as a consequence of deliberate selection for appearance. The severity of brachycephalic airway syndrome in English bulldogs is such that the breed cannot reproduce naturally and most individuals require surgical intervention to breathe adequately. Reform requires changes in breed standards, show judging criteria, and ultimately consumer demand for less extreme phenotypes.
