Where are scarewolves in dragon quest 9?

Answer 1

Zoom to Dourbridge, but don't enter. Instead, go south until you cross a bridge, taking you to a new area. You're now on a small landmass that doesn't lead anywhere else, but this is the Scarewolf's main spawn point, you should see them easily enough.

Answer 2

in the trees north of bloomingdale after the little bridge before the cave dont go towards the mountains.
