Nostalrius Begins - Quality wow vanilla realm (1.12)

So i turned lvl 10 made the hole taming quest chain and tamed "The Rake".
But he doesnt have growl, even tho he should, also when i tried out how to get it , i unlearned all talents of him, now he lost Bite aswell.
How do i get Bite back? And how does he learn growl? I checked the Spellbook, Pet section, nothing in there.

Beast Training in your general part of spellbook.

thanks
