Bull pet

I killed a bull looking animal with big horns in pre-searing ascalon and been looking for another ever since to charm it. So far i can't find it anywhere.
Are these things still running around in post-searing or did i kill a once in a lifetime opportunity?

You can't charm it anyways.

and just incase your wondering, it's the Rogue Bull belonging to Old Mack. You kill it for the quest Mesmer's Burden (from Lady Althea), it's only there when this quest is active.

Well too bad then but tnx for the info.
