Classic WoW Lvl 10 Pet Quest for Troll Hunter
This video handles 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 allows you tame beasts in the next order: Dire Mottled Boar, Surf Crawler and finally an Armored Scorpid.
After getting finished the taming part of The hunt chain, you will need to head to Orgrimmar and speak to Ormak Grimshot during the Valley of Honor as a way to unlock your Source companion pet managing abilities: Tame Beast; Feed Pet; Revive Pet; and Beast Training.
Eventually, don't forget to visit the Pet Trainer and grab the Pet capabilities that you need to give to your companion pet.
