It's pretty easy to tame
1. Bola it (so it can't chase you)
2. Use a slingshot or a club (I call them beaty sticks) to knock it out
3. Add some meat (it shouldn't take much)
Also, remember to dodge the poison spit
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.
