On my two previous attemps, my pet

Why do they turn out playful?? Can anyone give me advise on raising an aggressive pet? I try not to comphort pet unless his life is very low, or after the fighting has ended, and then only if his life is low enough to take the full heal spell. On my last attempt i did not use any non BM skills except troll urgent when needed. I am still taking some damage, mostly from life siphon, but i feel taht my pet takes a great deal of the damage. Am I healing my pet too often by using predator pounce? should i never comphort animal when not in battle? Is my pet not receiving credit for kills due to bleeding? In the old pet guide i remember something said about healing your pet and which evolution it takes, but i cannot remember if it said to heal often or not at all. Does my ranger need to gain exp in order to make an aggressive pet? I believe it would be near impossibe to kill lv13 MOBs with a lv 5 pet. should i rough him up a bit before i charm him?? plz help anyone if you can.
