To tame: don't miss around with hitting it and backing up,just start with a bola, then punch to your heart's content. Anything lower lvl in the wild doesn't even need narcotics of any kind, including berries!
I've always loved my 10+pack of higher lvl dilos. Dennis was my first. They're surprisingly useful at keeping you alive in sticky situations, have cute chirping sounds, and collect more meat then you could possibly find a use for. Great starter tame, one of my favorites.
1.kill some dilos, dodos or compy so that you can collect meat.
2.Craft a slingshot, wooden club or you can beat it with fist (If your trying to knock it with fists choose a low level one; if with slingshot collect a amount of stones first also remember wooden club breaks fast so craft and keep atleast 3 more wooden club for backup)
3.Find a dilo
4.after it's unconscious open its inventory by going near to it and tap and hold. After you need to put some meat which we collected at first
5. Wait.....if your dilo eats all the meat but still not tamed put some more meat to its inventory and wait......
