White Wolf  

As a pet they have a nice feature. If you charm the right one, there is a linked one with it, maybe more than one. If the wolf is being hit and howls, the second or the rest of the pack will appear soon. Saw a 40+ Lurikeen Invader with a pack on his heals after i send my wolf on his trail and he tried to kill it.
An other hunter told me when he was attacked by a frosthound there suddenly was an add. First he tought that was bad and he will die now. But then, to his astonishment, that second wolf helped him out of misery.

Neutral con, lack of faction, good cash loot (up to 35sp) and a wide ranging area to avoid over-camping. These critters are a friend to everyone power-leveling through their upper 20's
