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

Upon getting accomplished the taming part of The hunt chain, you will need to head to Orgrimmar and speak to Ormak Grimshot within the Valley of Honor so as to unlock your pet managing capabilities: Tame Beast; Feed Pet; Revive Pet; and Beast Training.

Last but not least, great post to read remember to visit the Pet Trainer and get the Pet capabilities that you will have to give to your companion pet.
