I wouldn't even bother. I am level 25 and it is a absolute nightmare to even try and get him. I have logged on the past week before I go to work and even in the early hours of the morning there are several hunters about. It is even worse that I am Horde. It is actually a bug that he does do shadow damage and was fixed in 1.8 or 1.9. The fact that we have weapon normalisation and Alterac Valley wolves do normal run speed should mean that Lupos should have normal damage.
Back on live Vanilla it took me ten minutes to tame Lupos because no one knew about him. The same for Broken Tooth as well. Not looking forward trying to tame that. Might just stick with my Rake.
