Very, very vague. All mobs spawn in "packs"... that's how minecraft spawns peaceful mobs, do you mean all the wolves should move in a general group with the alpha wolf? What would happen if the alpha wolf died? Can you tame the alpha wolf? If you can tame the alpha wolf, would the other wolfs *still move with it? Does the alpha wolf have certain attributes that other wolves don't have? Would wolves be assigned a pack, or follow the nearest alpha wolf? Can you create an image of what the alpha wolf should look like? Also, the A.I would be laggy.
