Just a reference to which canine would be more likely to be on a North Korea dinner table and which would be more commonly available in the USA, not an indictment of anyone's culture. (And yes, I know, the Doberman is German, the Beagle English.)
As to the list of animal protein consumed in the USA you forgot horse on your listing of red meats. It hasn't been that long ago that equine steaks and burgers were a possibility on the menu in the US. You can still find it commercially available in Europe, particularly northern France and Belgium. And while it's been a long time since I sampled a "Triggerburger" both rodent and lagomorph have been on the menu more recently. (Squirrel pot-pie or rabbit stew anyone?) Bon appetit!
