Interesting hypothesis, but in Korea, family pets are just as common as here. And they are as loved and wel-cared for as here in USA. There is a distinct seperation of 'pets' and 'food animals' made.
I have eaten dog, and a lot of other 'mystery meat' and can only say one thing - I ate it and have no regrets. It has not lessened my love or appreciation of animals. And if it came down to it; if I died and my animals needed food, heck..Munch away lads!
Its no use to me anymore...lol.
Other countries have different cuisines. And, sometimes, national food dishes are best left to the nationals.
