No, I'm pretty sure he's thinking Korea. This is what I've heard as well. I think the Phillipines also.
Really though, if you think about it, it's not "that" sick. Granted, I'd never eat dog personally, but it'd be the same as eating, say, wolf, which people would probably find far less disgusting. Americans, as well as other cultures, don't like the idea of eating dogs because they are commonly used as pets, and why would you eat your pet? Well, probably because your hungry.
