Selective breeding for extreme physical characteristics has created welfare problems across numerous popular dog breeds, with respiratory, neurological, skin, and eye conditions built into breed standards.
Conformation-related welfare problems represent suffering designed into dogs before birth through selective breeding choices. The scale of the problem is vast — French bulldogs are now one of the most popular breeds globally despite significant proportions requiring surgical intervention to breathe adequately. Reform requires action at multiple levels: breed standard revision, veterinary advocacy, consumer education, and ultimately purchasing decisions that do not reward extreme conformation with premium prices.
