Wolf packs are very organized because they follow "rules". The most important rule is that there are leaders and there are followers. The leader of the pack is the Alpha male and Alpha female. They are usually the biggest strongest and smartest in the pack.
One of the most important ways that the wolves communicate is through body language. Tail straight means means attack, tail down means neutral, tail around the back leg means fearful defense, tail up means dominant threat and tail down means submission. Have you ever heard a wolf howl? Wolves howl to reunite with others, so if you think you heard a Wolfman, you're sadlly mistaken. Wolfman was created because people thought his howl sounded like a monster.
A healthy wolf has never has never attacked a man and wolves are more afraid than you than you are of them.
Another way wolves communicate is by smell. Wolves mark their territory by urine and scat. This is called scent marking. When a wolf is out of his territory or clan, he can smell this and know that he'd better boogie out of there, top speed.
