UPDATE!!! She's an Arctic wolf! Arctic wolf (Canis lupus arctos) is a subspecies of the gray wolf.
In a second visit to this wolf pack I found out that this is actually an Arctic wolf. She was just in an enclosure with gray wolves and the signage did not mention the fact. Gray wolves can also be white however, so I suppose it is a gratuitous fact as far as art use goes.
