Try to find one who has strayed far from the pack or is by itself for it is nearly impossible to take one out without calling the other wolves attention. Use a bola on it and bring it down with tranq arrows. It usually takes about 4 or 5 arrows for me. Beating it with a club usually kills it instead
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.
