It's called brachycephaly which means short head. Brachycephalic dogs have a shorter nose and face in general, which leads to most of the mentioned problems: Teeth, ears (Bulla) and problems getting air. Distinct from that is the "wedge vertebrae" problem (spine and curly tail). Yet distinct is the chondrodystrophy: Shorter, deformed legs. The latter is more pronounced in Dachshund or some other bulldog breeds. Not sure if Boston terriers are that much better though. Don't have evidence in front of me.
