Where to see red deer rutting? (North East Scotland)

Anyone have any tips for good spots to possibly see the red deer rutting in North East Scotland?  Have a friend coming up here on holiday and would like to catch the red deer rutting, know of a couple of places where they may be seen such as Loch Muick but just wondering if anyone else has some places they'd suggest - I'm between Dundee and Aberdeen so within a couple of hours driving distance.  Places with a nice walk for the dogs would also be a bonus!
