Yes, it is true, I agree. They eat dog!! Can't believe that they can do such cruel things. Dogs is our best friend of us, but they kill them and cook them just because of trying to find another good flavor 
If you can eat beef, pork, mutton, venison, veal, fish, chicken, caviar.etc, then what is wrong in eating dog meat? Also, it is a part of their tradition. Who you are to order them to stop practicing their customs and traditions?
It's about the torture the dogs have to endure before they get eaten.
