I have killed over a dozen wolves, both healthy and infected, in Oceangreen Hills, and not one of them has dropped a Wolf Whisker.
In Oceangreen Village, I have gotten drops about every 6-8 wolves killed. The problem with OGV, is there is not enough wolf spawns. Not sure what their placeholders are. Snakes? Rats? Bats? Undead? *shrug*. Very annoying to run out of wolf spawns for such a rare drop. EDIT: I started clearing the zone of every mob north of the Temple, both sides of the path. I started finally getting a good amount of wolf spawns. They seem to be mainly concentrated on the North West quadrant of the zone.
Maybe recycling the missions for the zone will be the way to go for a refreshed zone that may contain several wolves each cycle.
EDIT: Can confirm that Wolf Whiskers do drop in the Mission: 'A Dread Challenger'. Wolves were mainly populated on the north half of the zone. Out of about 10 wolves in the zone, I got 2 whiskers to drop.
