Their compressed airways make breathing difficult during exercise, heat, or even rest. Many require surgery just to breathe normally. Bulldogs, for instance, frequently need cesarean sections because puppies' heads are too large to pass through the birth canal naturally—a clear sign that breeding has pushed ph...
