I roamed the center tiles of the quest area in the zoomed in map until I heard wolf's howls, then I leashed and fed my dogs and unwielded my weapons. Then I continued carefully toward the howlings, waiting a few turns between every few steps, until the wolf appeared. Then I dropped 4 spots of "bait" and flatbread, slowly moving backwards. Luckily I was in a heathland so I could keep the wolf in my sight while dropping stuff and strifing backward with crtl+movement. I then waited a bit. The wolf did not attack me (probably because I had my dogs on a leash and I was unarmed). It ate a fresh meat cut but not the flatbread, then walked around for a while, then ate a second cut and the flatbread with it, and immediately fled. I returned to the village and completed the quest.
