It's useful to ponder if our personal biases make any sense. For example you seem to readily believe this dog torture = flavor argument that's perpetuated, after all that's why anyone would bother.
If that's the case, it should also be true of other mammals, ie the beef/pork business at least in china. So can you bother to do some basic research if that's true? Surely trivial for such large and visible industries.
Now I'm not saying it never happens, because all sort of folks believe/do crazy shit, but most of the time it's overblown niche cases. For some perspective, many people around the world believe in similar exaggeration about the US, like schools are scary because of all the shootings, etc.
