You have 3 challenges to do. The main part is the each challenge you complete you have to knock it out again and ride it each time. I'm not sure it'll be in order. 1st after riding it they'll try to shake off of you the mini game is that you have to maintain a blue bar to where the arrow is. The 2nd it'll point out what dinos to kill you have to kill a few of em. 3rd you have to feed (ext. Kibble for ez progress) it'll try to bite you before it does you feed it pressing F. (Similar to the octo taming) after all 3 challenges are done you have to knock it out again to really start the taming. P.S I hope this helps lol
