The Old West wasn't wild just because of the people. Even the animals wanted a piece of the action. Hunt animals that come across your path, and maybe everyone will get dinner tonight. These missions are triggered by talking to the Indian Hunter near Piper Lake.
You begin to hunt take to the native American hunter. First things first you need a bow as apparently killing them with a bullet takes no skill and I'm glad the bow is a fantastic weapon. Next you will need to find your prey going only on the hunches the hunter will give you, well you don't as I'm doing the work for you yah lazy beggar. Once you close on the are of your prey you will get a message saying that it is near that's your cue to get off your horse, I repeat get off your horse. Now you creep up on your prey by crouching and treading lightly aim with the bow and zoom. You will get another message telling you when your in range, aim for the head and let arrows fly. If you miss of hit the body the animal will generally run off and you have to find it again but sometimes it'll just run around in a circle leaving you aim again and this time don't miss. Remember aim for the head no matter how many arrows you put in the rest of the creature it won't die.
Grey Wolf
The Grey Wolf can be found in one of two places - either by the bridge to Dodge, or by the ranch where you chase Chavez y Chavez. Either way, the strategy is clear - sneak up on the wolf and shoot it in the head with the bow. Using the bow is CRITICAL in these missions, as if you use your guns, the result is that you destroy the pelts and lose money for it; for the same reason, only use the Apache or the Blackfoot Fire bows, not the Dynamite Bow. When outside Dodge city the best place to be is on the other side of the rail tracks away from the wolf because if you miss, the wolf will run away in your direction giving you another chance to hit it in the head.
Great White Buffalo
It's on the plains just outside the ranch, the best position for you be in is by the hilly side of the plains as if you miss it'll run towards you giving you another chance to hit it in right between the eyes.
White Wolf
This she wolf hangs around either Piper Lake or the Apache's tribal grounds is you don't know where that is it's also where you meet Soapy after the steamboat ordeal. If your around the Apache's tribal site then approach from under the bridge as once again this is the way it will run towards if you miss or spook it giving you a chance to hit it where it counts, the head guys, come on focus.
Great Mountain Lion
This appears to the east of the hunter in devils canyon go past the rail tracks and into the track that has brown soil. Now this is an odd one as it will just get running around in circles if you miss so the only danger is if you run out of arrows.
Black Wolf
The Black wolf appears in the hilly part of the plains outside the ranch by the old mine. Approach from the west side as that's the way it seems to run, you should know what to do by now.
Hunt The Grizzly
Those of you paying attention would have noticed that is a mission so that means you don't have to use the bow, thankfully. Head over to the empire you're guided now so it shouldn't be hard to find but encase you can't find him he's at the end of the gully that runs alongside Empire. Now the first thing to do once you've seen it is get off your horse and get it to a safe distance away, not too far mind as we'll need it later. Fight the grizzly as you fought the bear back at the start of the game, avoid it's charges and blast it with the shotgun. After it's taken a large amount of damage it'll run off. Now you see why I told you to get the horse safe, without it, it'll get too far ahead and mission failed. Once you've cornered it start the battle again, be wary as the grizzly will have full health again. Once you've don't that you've finished all the hunting missions, yay for you, apart from you've been cheating by reading this.
