These wolves spawn only in packs and are 1000% hostile to everything they encounter quite wandering around. Use a Fabricated Sniper Rifle to weaken and get killed the weather wolves you don't want to tame, and letting the 145-150 Alphas survive. Then help the Alpha win against that Mammoth that killed it's pack, with your rifle. Bola and tame it after.
These things are really fun to tame. I once knocked out a lvl 95 Female and a lvl 45 Male in the same trap. I stood there and watched youtube while slowly feeding them narcs while they tamed. Later on I had to leave and thus I realized. The lvl 95 was NO way near being tamed. I sacrificed the 95 to the 45 for food.
These things are great scouts and have amazing damage for their size. Be careful when taming. Try to trap them so they cant hit you or escape when taming. Always make sure you have stamina on them as they dont move fast when winded.
