Well, in reference to the "XO wolf" comment, they are called the Beta wolf. The chain goes like this:
Alpha: Top of the heap, gets to mate (the others dont). Note that there is both an alpha male and an alpha female.
Beta: Second to the Alpha's, but beats down everyone else, will likely take over if the alpha dies.
Omega: The douche-bags. Dont get to mate, last to eat at a kill, etc...
I'd probably be Beta. I'm not motivated enough to be the Alpha, but I'm also a pretty big guy.
