I did this about 3 times and believe me . Wait to you pull it it off succesfully and then an 'event' happens and all the wolves die . I finally went hunting at night and used the 'tame ' command after building a rather large corral to keep them in . A little cheezy i know , but I had wasted a lot of time trying to do it within the mechanics . Tamed them and walked them back to the homestead , fed them well and they multiplied like rabbits . I am highest level atm and have killed all bosses so i get some pretty tough attacks that can wipe out a lot of my star wolfs .
