After taming 100's of Valheim's creatures, starred wolves are the most challenging, in my experience. It is important to be in such a spot so that you can see them, but they can't see you. Often they will not feed to begin the taming process, unless the aiming reticle shows nothing detects you at all. To clear the reticle, put a little distance between yourself and your target (after throwing in some food), with an obstacle between, and pan your aiming reticle away, being careful to retain a peripheral line of sight on the target, preferably from behind it. Placing some floorboards around the edges of the top of the taming pit, with enough of an opening to be able to throw in food, not only helps to keep them from detecting you, it also prevents drakes from seeing and attacking them.
