This video covers the Taming the Beast quest chain from the point just prior to Thotar offers you a taming Rod for just a Dire Mottled Boar in Razor Hill. Thotar gives you a series of 3 taming rods, every one is different and allows you tame beasts in the next order: Dire Mottled Boar, Surf Crawler and finally an Armored Scorpid.

Upon getting accomplished the taming Portion of The search chain, you will have to head to Orgrimmar and talk to Ormak Grimshot in the Valley of Honor in an effort to unlock your companion pet handling skills: Tame Beast; Feed Pet; Revive Pet; and Beast Training.

At last, don't forget to go read review to the Pet Trainer and get the Pet capabilities that you will have to give to your companion pet.
