If you see one of these things chasing after something by itself it is usually alone, so take the opportunity and chase after it and bola it. After you have used the bola, get out or make a wooden club and hit in the butt or on the side so it can’t hit you back. After you have done this and it is knocked out, put some prime meat in it for level ups and put some regular meat in it so that it has 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.
