Breed health reform campaigns are making progress in addressing congenital welfare problems in extreme dog breeds.
Brachycephalic breeds experience chronic breathing difficulty, overheating, eye problems, and dental crowding from extreme skull conformation. Breeding toward less extreme morphology improves welfare without eliminating breed character. Progress requires collective action from kennel clubs, breeders, vets, and purchasers. Consumer demand for extreme appearance perpetuates the breeding that causes suffering.
