I should say one of Rowdy's odd quirks. I cue my dogs on "mark" prior to launching birds when we arrive at the mat and he has had time to look around. All my previous dogs when I cue mark will perk up their ears. Not Rowdy. When he gets to the mat his ears are already up. When I cue "mark", he tilts his head slightly to the left and down for a brief sec.
I guess this is his way of acknowlegding the cue. Anyone else noticed anything like this?
