Wolf

The  is one of eight possible pets in Torchlight II.

Inspired by the original 'Dog' pet of Torchlight, we went for bigger, better, and more badasser (that's totally a word). The Wolf is an all-new pet, brawnier and bigger than its domesticated cousin. Leaving paw-prints like dinner plates, man's best friend is also a Sturmbeorn's worst nightmare.
