Some points as FYI to clear up any confusion or assumptions:
-Koreans eat dogs just like you would beef, chicken, etc. They're prepared nicely, and it's a great dish.
-This DOES NOT mean they fucking go around killing and eating stray dogs or neighbor's or their own pet. Koreans LOVE dogs as pets too. They don't eat them. They're a first-world country.
-Most Koreans don't eat dogs. It's usually the older generations. Majority of people 30~ or under cringe at the thought of it. It's just like Americans frowning on bull testicles. Some eat it, doesn't mean all do.
