Forum:Giant gray wolf

I'm trying to find out what the giant gray wolf is. yesterday i started the master hunter challenge 10, and i found gordo, then about 30 seconds later i found a huge gray wolf surrounded by about 10 little normal gral wolves. it popped up on my screen saying i located a legendary animal and i killed it thinking it was lobo. then i went to sleep. when i woke up this morning i went looking for brumas, but i ran into lobo the black wolf. im trying to ind out what wolf i killed last night.

Thanks
