this is silly because you're talking about domestic dogs ie those owned and bred by human beings, and floppy eared dogs have been around since recorded history
a wild canid with prick ears can't do anything about a tick embedded in its ear, or if a wound around its ear gets infected
they can't do shit about dental disease/losing a tooth either
a human that diligently cares for a floppy breed's ears/teeth will never have the dog experience illness from those vectors
nothing about a domestic animal is free from deformity in the first place, just because dogs with prick ears can look more like typical canids, they are still 100% domestic dog, ie neotenous mutant
