To tame a dire wolf the fastest and easiest way possible, you will want to have an Argentavis (preferably one with high stamina.) You then want to go to the edges of the North zone, so you don't freeze to death, and then find a dire wolf of the level you want. You then want to pick your chosen dire wolf up and carry it back to your base or an area suitable for knocking it out and taming it.
Make a little trap carry with argy ( it can still attack your argy so give it high health ) then drop in a trap.
No need to worry about the pack just pick the leader or the one you want.
Once you have three you get a pack bonus and a leader bonus for highest level wolf
