What is the Most deformed breed of dog?

The most deformed breed of dog is often considered to be the French Bulldog, largely due to their brachycephalic (short-nosed) structure, which can lead to various health issues such as breathing difficulties and dental problems. Other breeds like the English Bulldog and Pug also exhibit significant deformities related to their physical conformation. These structural traits are often prioritized in breeding, sometimes at the expense of the dogs' overall health and well-being.
