Go complete the fourth quest in the chain.
Can't remember but it's basically a "Go talk to this person" quest that teaches you Feed Pet, Dismiss Pet, and something else(I believe it's Train Pet, I can't remember if you buy Mend Pet from hunter trainer, it's been a while)
Edit: changed it from second to fourth even though I consider the 1st three basically the same quest only with different animals to tame, technically it is 3 seperate quests :-P
