A non-Asian descent Canadian who lived in Pusan, Korea for a few years, is me. Bo-shin-tang (dog soup) is far from being a 'fading' element of the cuisine. The pungent-smelling Bo-shin-tang shops are everywhere in urban South Korea. It is believed that, along with a seemingly endless variety of other foodstuffs, that eating dog soup will contibute to one's 'stamina', a euphemism for sexual prowess.
Dog soup is quite delicious, especially when accompanied by a lot of beer and soju. The smell takes some getting used to, likewise the forlorn reddish-coated dogs that are the favored eating-breed.
Meat is meat, though.
