- / Patch 4.0.1 (12-Oct-2010): Changed from Increases melee and ranged attack power by X for the wolf and its master for 20 sec.
- Patch 3.2.0 (04-Aug-2009): Ranks 1-5 will no longer give slightly more attack power than is listed in their tooltips.
- Patch 3.1.0 (14-Apr-2009): now stacks with Battle Shout and Blessing of Might, however, it only affects the wolf and hunter. Its effect and cooldown have been doubled so that it provides the same benefit but isn’t up 100% of the time.
- / Patch 3.0.2 (14-Oct-2008): Description changed from "Party members within 15 yards of the wolf receive an extra X damage to their next Physical attack. Lasts 10 sec." to "Increases melee and ranged attack power by 2 for party and raid members within 45 yards of the wolf. Lasts 10 sec."
- Patch 1.7.0 (13-Sep-2005): Added.
