I knew that scent was important and I discovered that if I put on different clothes or washed or at different food, the beta male would start nipping me again until he was satisfied that the new smell didn't mean I was going to react differently to his approach or that my mood had changed. The other high-ranking wolves did the same thing, but it didn't involve every wolf in the enclosure. The lower-ranking members of the pack, I was to learn, don't question what the higher-ranking members decide; they are foot soldiers - they have an important job to do, but it is not to think for themselves.
