The wolf code

The Way A Wolf Pack Actually Works- I've seen a lot of rumours going round lately about the social structure of wolf packs. Things like they're being a single alpha, the Omega being the lowest rank and elders being left for dead. None of this is true! So I created a brief description of each of the ranks in the wolf pack. None of the images are mine, I do not claim ownership of them, they were used to make this description better.
