The way you're doing it, he's not dealing much damage and since he's dead, he's not taking much damage either. Therefore he will not evolve. He will remain unevolved all the way to level 20. For all intents and purposes, he is equivalent to an "Elder" pet, but his name will not change. It's like you trained him to be first aggressive, then hearty.
If you want aggressive/dire, you need to stop killing bad guys and let him kill everyone without taking too much damage. Try lower level baddies in the Old Ascalon for the first few levels and use symbiotic bond or something that will reduce damage to him.
