most of the dire wolfs come in packs if you see one alone there most likely are some still around the corner, watch out for when they howl the pack comes! also dire wolfs are pretty fast so if i was you i would tame a bird first, the bird could easily pick one up and put it in a trap (if you make a trap) the bird could also be an quick escape, the best way to get one trapped where you can knock it out is if it eating/killing/fighting something but beware the thing it is fighting will try to kill it when its knocked out
