Easiest way to tame is knock out the Pogo and build a small pen around it that pretty much only the two of you can fit in. Be cautious though because it doesn't have a torpor meter, it will lose health. I don't know the exact amount but it seems to be a percentage based off of its health. It will not lose tame bonus from this, just make sure to swap your berries to the last slot in your hot bar. You will need a couple hundred berries I tamed a lvl 25 and it took about 4 stacks on a 1.5x taming weekend.
