How can you have a white pup on wolfquest

"when you start the game, make your wolf a white wolf. At least one of your pups should turn out white. If you want to be doubly sure, choose a white wolf as a mate." actually, that's not true, you need 50,000 xp points by hunting, chasing off wolves, ect and if youre a white wolf with a white mate you will actually get a grey pup...
