i used to have 257 skining, but got rid of it, now i have it back im lvl 41, so  where can i raise it without looking for lvl 4 wolves?

You cant u have to start all over and go back to kill the lower levels

yea i did that too... when i was like lvl 15 i had like lvl 80 skinning but i dropped lw and skinning in favor of herbalism/alch... i recently picked it up, now at lvl 43 i am lv 130 skinning, i just go to duskwood and skin and skin and skin... if u devote time to it not questing, etc., it will be at a suitable lvl in no time.... major pain in the ass though lol
