The dog is a genetic engineering monster from the USSR, and it only eats "Tourist Breakfast," but since the infamous USSR collapsed and "Tourist Breakfast" is no longer available, it starts eating canned McDonald's (i.e., Americans)))) And since the dog is from Chernobyl, it also loves nuclear power plants))) Well, of course, and barrels of nuclear waste.
Okay, but there's also a mega battle between an American kitty and a Soviet dog...
