The howl sounds a mere block over from Vincent's position, alerting him quite clearly to the pup's location. To Matthew it also seems that he is close to the new wolf, and should be able to reach him shortly.
Meanwhile Jeremiah continues to run, the pavement of deserted city streets giving way to the soft grass and hard tombstones of East Lawn Memorial Cemetery. And as he runs he begins to get the feeling that there's something above, something watching.
Matthew and Vincent can both catch up to Jeremiah in their next post, and all werewolves near him (including Jeremiah himself) should Roll Wits + Occult + Primal Urge.
