I would call it more BS and false advertising which seems to run rampant in the hog hunting industry.
Russia is a country. Hogs born in Russia are Russian and if a boar then a Russian boar. Russian is NOT a classification or name of any species of hog. So to technically and legally be a Russian boar the hog would need to be a male born in the country of Russia. So any and all places which advertise REAL RUSSIAN BOARS is flat lying unless they personally imported them from Russia.
A more proper term to use would be European boar and even then unless the one you shoot was imported it really isn't that even. Black is the normal color for them so yes I'd say any white one would need to have pink eyes and no color in the hoofs to be an albino and if not that they it can be white only if bred for that coloration meaning it would not technically be pure. But realistically all hogs came from the same European brood stock and all are the same species even those bred for the commercial grocery store market.
