How to track: Like the other trackable hunter pets, you will not be able to see him when he's up. He is completely stealthed. In order to locate him, you will need to find and follow his tracks - tracks that thankfully only hunters can see. Once you've found his tracks you'll need to follow them until you don't see any more. This is where I like to wait and watch where I think that he'll be walking next. Often times you'll see a new track appear right in front of you - this means you've found him!
Once you find him, the only way to see where he is, will be for him to walk through a flare. Don't throw your flare down on top of the track he just left, throw it a little further out in front of where you think he is. When he walks through your flare he will become visible. You can take this opportunity to tame, or you can throw a Hunter's Mark on him - which will keep him visible to you when he goes back into stealth. Hunter's Mark will make him visible to you, but only you when he's in stealth.
Bristlespine's tracks are called "Puzzling Tracks", and they look a wee bit large for the size of this little fellow. Like other beasts' tracks they do not stay up indefinitely; the furthest ones behind disappear one by one as new tracks are created. His tracks are dark green in color and most of his path is along dark brown grass, making them a little difficult to spot at times. His tracks are definitely easier to find if ground clutter is turned down to the lowest setting.
(Tracks are now facing the correct direction as of patch 5.1. You no longer need to follow them backwards.)
The Southern end Bristlespine's path starts on the Auburn Bluffs overlooking the sea and The Jade Forest. From there he basically makes a large oval through the entire southern half of the zone until he reaches the northern Auburn Bluffs, just south of the Temple of the White Tiger. It takes him about 45 minutes to move from one end of the path to the other. When he reaches the end of his path, he simply turns around 180 degrees and heads back in the direction he came from.
