Summary — Moving to a different part of the yard. Session 25 (6 mins) 2 sets, 7′ apart; session 26 (4.5 mins) 2 sets, 7′ apart; session 27 (6 mins) 2 sets, starting 7′ apart and moving to 4′ apart mid-session.
You can immediately see that moving to a new part of the yard threw him off. It just shows how important that really is. You never know if they’re thinking “I need to wrap around the first pole and enter” or “ok – I head toward the aframe and then make a u turn when I see the dogwalk and then enter”.
He also started having alot of trouble with the first set once I added the second set. I still occationally reward in the middle, and I don’t think his problem is not having enough value in the 1st set. If that were the case, I think he would cut it out all together. But it’s like he wraps around the first set and doesn’t see the opening the way he used to. Perhaps he’s already shifted focus to the second set. At any rate, he has a definate weak side. (See Part 1 ~1:10-1:55) This is one of those moments where I have learned to have faith and wait him out. Hubby’s not sure he could stand there and let them fail so many times in a row 
I also realized at this point that I hadn’t added enough body motion at the 2 pole stage. I partly simply forgot. And I’m going to play the pregnancy card – moving is a wee bit difficult at the moment. Looking back – I think I probably added too much movement too quickly. You can see a particularly troubling segment at Part 2 ~2:35-4:36 – though I also seem to recall that after that session he walked right off the field and pooped 
That might have had something to do with his lack of concentration. Yet another lesson learned
This first session with the poles at 4′ apart was particularly tough with alot of failures. We’ll have to see what future sessions bring!!!
