Your wolves are not in the wild facing privation, where hierarchy determines who eats first and those at the bottom don't eat at all.
Your post no. 231 - Try telling them that! Their is definite heirarchy as to who gets what. It is just mainly a showing of teeth and snarling but not biting or attacking each other.
The Alpha is responsible for feeding the pack. They control the food supply.
They feed the pups first, then the weak and sick, and they will eat last or not at all.
As I explained in post 210 the hierarchy changes often due to the demands of leadership.
