Wow! So much info! Thanks a ton Bob.
I also really like the teamwork in a pack of wolves. In one of my wolf books, there was a section about the pack, and one part of that section showed a soaked adult wolf that was lying down in the snow, with a bunch of other adult wolves licking it. It looked like it was dead, but what had happened was it had fallen into a stream, and the other wolves in the pack had just recently pulled it out. You could see the alpha male welcoming it back as well, which was cool.
Another cool thing about wolves is how they act around the alphas. When they are around either of the alphas (whether the male or the female) they are not allowed to hold their head higher, they are not allowed to have their fur standing up (it has to be flattened), and they always have to lick or rub against the chin of the alpha they are around, as a sign of respect.
