Tame a 135+ and you have a great companion. He/She can slow down attackers when on your shoulder by throwing poop at them (even alphas and brontos), collect berries when on wander and makes a surprisingly good guard dog in bases. I get mine to 1k health then pump melee. I usually get 400% minimum, that's 40 damage on a small, fast, pooping flinging creature. It'll rek wanna be intruders in your base, especially I'd you put a good helmet on it for armour.
