Now Level 5

So I am now level Five in World of Warcraft. I hope to soon train my bear with the pet trainer if that  is possible. I still can't find any more of the beers I am supposed to be looking for. I had to go back to my original town because the foes in Dun Mough were too difficult and killed me. A wolf killed me and attacked me without any warning. Has this happened to anyone else? I had to resurrect myself and my bear at the graveyard. Does anyone know where to find the other beers I need?
