The best way to tame a dilo early game is to weave about so it can not hit you with its spit attack, just after it spits at you run in and start trying to knock it out ( punching works if there is no alternative) repeat this proses every ten seconds to avoid the spit . On a final note choose which dilo to attack carefully because you can easily be swarmed if there are any other dilos in the area
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......
