When you're on the quest A Dire Situation you get Rina's Diminution Powder which you can use on wolves, so they shrink and become friendly.
This is in Blade's Edge Mountains.
BUT, if you have a pet attacking it while you're throwing the dust on him, he will still stay hostile, and you can skill your weapons without the wolves attacking you back.
