The strongest Dragon Wolf, is either just pure AI, or Wrest Mastery. The Disarm and Paralyze from Wrest Mastery aren't all that useful, but the Knockout passive and Fists of Fury are. Knockout will increase auto attack damage (with a pretty wide range), and Fists of Fury is a retaliatory ability that'll trigger when they're hit (melee or magic) by an enemy within 2 tiles, and it'll attempt to land three attacks instantly. Against foes weak to the pet's elemental damage type, Fists of Fury can be devastating when all three hits land.
Here's a 3 hit Fists of Fury against a low resist target. 381 total damage.

The Dragon Wolf also has Dragon Breath, and Dragon Breath appears to have a 18-20 second cooldown on it. Dragon Breath appears to cap at 200 damage, and that's at 1,024 Health against a 0-2% Fire Resist foe.
