The cultures that eat dog meat have no standards as to humane treatment for the animal. Yes, there are flaws and problems within the US slaughtering industry, but their are rules and inspections and an attempt to be humane. In cultures that eat dogs they have no standards as far as treatment in raising and killing and in fact it is common practice to make the slaughter as painful as possible and the animal to suffer as long as possible because they believe the meat will taste better.
There is no reason to be intentionally cruel and barbaric to ANY animal raised for food. And that they do it to an animal that has been domesticated over the years to be "man's best friend" just makes it more heinous.
I have said this before, cultures can have their differences, but some things are just WRONG and standing behind "culture" does not make it right.
The Olympics being held in China should be boycotted because of the attrocities China is known for in it's treatment of animals as well as it's people, and all the recalls because of lead paint on children's toys and lethal ingredients they have put into products and shipped.
