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.
In that case, banning dog meat all together will not solve the problem. The activists should rather concentrate on encouraging humane slaughter of the dogs. I guess the dogs are beaten to pulp before slaughter to increase the tenderness of the meat. They do that for all types of meat, including mutton, venison, and pork.
