Wolf Ranks...
ALPHA- The leader of the pack. Usually the strongest and bravest.
BETA- The second in command. Betas help keep the law and aid alphas with decision making.
SENTINEL- In big packs there are two pairs of sentinels. In smaller packs there is one. If the alpha is sick, lost or cannot lead the pack the sentinels take over. But they are only temporary. (They can also become beta wolves)
OMEGA- Omegas are the lowest ranking wolves. They really have no say and just go along with the other higher ranking members. They also keep the pack's spirits high and help keep the peace.
