This tutorial covers the Taming the Beast quest chain from the point just just before Thotar offers you a taming Rod for a Dire Mottled Boar in Razor Hill. Thotar offers you a series of three taming rods, each differs and makes it possible for you tame beasts in the following order: Dire Mottled Boar, Surf Crawler and eventually an Armored Scorpid.

Once you've finished the taming Element of the Quest chain, you must head to Orgrimmar and speak to Ormak Grimshot during the Valley of Honor as a way to unlock your companion pet handling skills: Tame Beast; page Feed Pet; Revive Pet; and Beast Training.

At last, don't forget to go to the Pet Trainer and get the Pet abilities that you need to give to your companion pet.
