Oh Goodness. These things are on crystal aisles and It was my first te encountering them EVER. I thought they'd be a piece of cake to kill. After getting killed 4 times back to back my mind was changed. I'd rather encounter 2 Gigas and 5 rexes than deal woth them. They're like Haeyandadons on steroids and super aggressive
If you encounter one of these wolf like creatures then hit it with a bola then can either shoot it with a bow/crossbow/gun or run. You can also run into water because they cannot attack you and eventually they will run away. Stay safe survivors!
