A major tip for taming dilos would be if you see them in a pack, ( The highest number of dilos in a pack is about three ) craft a few bolas and go off. The perfect knock out weapon for dilos is a club. I use my Axe first to drain dilos health. Over all dilos are easy tames and can farm hide that for people in the early game can be hard to get. But as soon as you unlock the crossbow try to tame what is basically the better version of the Dilos the Raptor.
