This video covers the Taming the Beast quest chain from the point just before Thotar gives you a taming Rod for your Dire Mottled Boar in Razor Hill. Thotar provides you with a number of 3 taming rods, every one is different and lets you tame beasts in the following order: Dire Mottled Boar, Surf Crawler and at last an Armored Scorpid.

When you have completed the taming Section of the Quest chain, you need to head to Orgrimmar and talk to Ormak Grimshot inside the Valley of Honor so that you can unlock your pet managing capabilities: Tame Beast; Feed Pet; Revive Pet; and Beast Training.

Lastly, do not forget to go to the Pet Trainer and get the Pet look at this site abilities that you need to give to your companion pet.
