Here is a summary of the entry in the Kwick Training Journal (the photos may help):

July 17th - set up a new drill called the "No-No Push/Pull Road Drill" to work on Gunny's "lock"

1st identified the visible 25 yard pile pile from between two stickmen on what will be the far side
of a gravel driveway (referred to as road from now on) Gunny lined the pile a few times

2nd lined the pile again going between 2 bumpers placed on the near side of the road, but from
a position where the pile is the target and these two bumpers are clearly out of his peripheral
focus, after crossing the road. Gunny No-No'd the stickmen and lines the pile

3rd Gunny's next run is from a line far enough back of the diversion bumpers to need to be
push/pulled to the center (away from them).......he splits the visible diversion bumpers this side
of the road, crosses the road, No-No's the stickmen & lines the pile, which is not visible from the "third" line because the road is higher than both "grassy" sides  (not unlike running out of a ditch
and into another)

note: Gunny never picks up the two bumpers he is "pushed" or "pulled" off of, he has essentially three things to "click" on, the correct one is straight ahead & not immediately visible (but he has
a clear mental picture of its existence), with the tree line in the far background he is locking on a direction

note: Gunny was giving me three distinct "clicks"....off the cues....."no"..."no" and "good" which
was the primary goal

note: The fact that the pile becomes quickly visible is kind of like a pop up blind. It is an immediate reward for making the right "lock".

                                                 The Analysis and Rationale

I have figured out a reason this may be effective. When doing a wagon wheel split, the dog will look down at the near bumpers and must raise his head to look longer. In this drill all the "attractants" are at eye level.......because they are "up" on the road or beyond. The dog is looking forward at the same level.......at something or "out". The premise is that it is more difficult to ask a dog to look up when he has been looking "down" (i.e. bugging).

This morning something unusual clarified this idea. My pup had just finished a water lining drill and was being walked back to the van. We passed beneath the second story, raised deck of the owner. He and his wife started talking. The pup was jumping all over the place and barking trying to figure out where the voices were coming from. He never looked up......only straight ahead. Gunny was confused.....there was no one there.

Now if a pup has to learn to look up......it seems looking out (at nothing) might be just as difficult. So anticipation must be developed, distractions must be ignored and looking in the right direction must be taught.

Daisy is my three year old. Up until about three days ago she was taking cues and "looking out"
on blinds really well. I think she is about to come in heat and has become a bit "buggy" on her blinds. Her focus seems to have diminished.

So this morning, I ran her on this drill. After about five or six goes, the "Stevie Wonder" disappeared. She was sitting up tall and looking out. Her attitude changed dramatically. The attraction of the stickmen and visible bumpers gave her something to look at....a focus. I could "no" her off "something" rather than "nothing" a lot easier. That left the pile of bumpers "out there" that she could NOT see as the "good". Anticipation was the new focus, and since
everything was at eye level.....looking out was easy. Daisy was not confused, and her attitude improved.

note: The key is having "things" at eye level when sitting high.

With "reps", I can see where this might help break the pattern of "huge, meaningless clicks".
