I'm not a dog owner myself, but see a lot of pugs around here. It always makes me wonder why people would buy a dog that's well known to have breathing issues because it's been bred to be malformed. But maybe the main question is why breeders have created the extreme face shape of the breed in the first place. I just saw a thread on here from someone thinking of buying a German Shepherd puppy and almost the first reply was to watch out for back problems since they've been bred to have their front half much taller than the back.
Naively I would have thought that people who breed dogs carefully (not talking about puppy farms or anything) and those who set the standards go into it because they're dog lovers. So why do they take healthy dog breeds and make them less healthy?
