They seem to like a bit of abuse. If the Pego is standing at your feet staring up at you, as they often do while i'm trying to tame them, you can punch them causing them to retaliate and steal from you. This didn't lower the taming effectiveness any, and don't worry too much about knocking it out as the tamkng progress doesn't drop while unconscious.
literally bought console ark after playing mobile ark for ages, this little sh it came and robbed me of my tranq arrows, then, had the audacity to come and tame itself on me after taking my 20 mejoberries, didn’t want this pet but I took it home, died 20 seconds later to a bird that picked it up and ate it, still don’t know why or how but I also don’t care
I was throwing away stuff from my inventory and a pego ran at me and the for some reason it said you tamed a pegomaster and I was sitting there for five minutes like what just happened and how so I guess you can tame a pegomaster by chucking junk at it so yea that was weird
