Patch 6.2 features 8 new hunter pet looks. There are no rares, but one of the new pets is a challenge tame — the Felbound Wolf. You can learn more about how to tame that in this post.
The video below will give you a quick look at 7 of the new looks. The 8th is a red worm pet only available if you’re on a particular part of the garrison campaign (I’m past it, so I couldn’t tame it for this video). However, if someone in your party has the quest you should be able to see the worm.
