benefit: dog meat is actually tasty
I dont see why we should discriminate dogs and cats not to be eaten and cows and chicken to be eaten. I mean westerners eat cute Rabbits. I do believe though that we all need to reduce our consumption of meat not because of the animals, but because of the environment. I rarely eat meat.

Also not everyone eats cats or dogs there, just a few. Less people for sure than there are western people eating rabbits. For me it was an interesting experience though as a tourist.
