The guy that "breeded" them, may not have actually had wolves. There are many out there they just say they are to make more money. If a breeder ever calls one a cub that is usually an easy sign to tell, as they are pups not cubs... Gotta be careful with shady ppl. Also, as stated above they mix them with alaskan malamute also there are a few others... I don't see how they would "end up dead" shortly after it...
