Private Training: T-drill, blinds, and diversion

Today we again had two outdoor sessions, early afternoon and late afternoon, the latter with Nate as helper. In each session, each dog had one series, for a total of four series:
  • Series A: Laddie on T-drill
  • Series B: Lumi on triple blind
  • Series C: Laddie on T-drill
  • Series D: Lumi on diversion drill
All work was done in a steady rain, with temps in the mid-40s and wind calm. Series A and C were done at the neighborhood lacrosse field, which I've selected as our fixed location for T-drill and later configurations built onto it. Series B was at a new homes construction site in low, clumpy cover and irregular footing, and Series D was on the ballfields at Sundown Park, with different lines of sight than we've used before.

I chose a fixed location for the T-drills per Alice's advice in yesterday evening's correspondence. The training plan for the T-drill was based on Alice's accompanying instructions, similar to but in several ways different from the diamond drills I ran Laddie on yesterday.

Laddie's T-drill was constructed as follows:
  • Pole P at 40 yards from the start line
  • Pole 1 at 40 yards to the right of pole P
  • Pole 2 at 40 yards behind pole P
  • Pole 3 at 40 yards to the left of pole P
When I lengthened the T-drill from 20 yards (center to each pile) yesterday to 40 yards today, Laddie's whistle sit (WS) problems disappeared. We did two sessions today, a total of 17 sends, about a dozen of them with a WS at the center, and Laddie didn't slip one of them. He also didn't refuse a single cast.

However, he developed a new problem, what looks to me like an avoidance behavior. It started near the end of the first session, then resumed in the second session and became so frequent that I finally quit the session after 7 retrieves with 3 still to go.

The behavior was that when sent out, he'd veer immediately to left or right about 45 degrees, stop after about 20 feet, and begin sniffing or eating the grass or something in the grass. If it was avoidance, I don't know what he was avoiding. Some possibilities:
  • Were the whistles hurting his ears? From cleaning his ears, I can see that he's fighting an infection in both ears. We're seeing the vet on Thursday.
  • Was he bored being sent the same direction from the same starting point over and over? Based on past experience, I don't tend to believe that dogs get bored, but maybe I'm wrong.
  • Did he, like Lumi in the past, find so many WSs at the center point on the way to dummies at pole 2 demotivating?
Lumi did great on her triple blind. I found a site almost exactly like one of your diagrams -- a wide ditch where I could send her straight across and at an angle in both directions. She didn't seem to square the ditch. Her biggest problem was some white soil-lining material sticking out of the ground to the right of the rightmost line. She was convinced that was where I was sending her and took three casts, ending with a straight "over", to pull her off that line.

When we did the throw-toward-line (TTL) diversion drill (DD) later, Lumi's performance on the retrieves to the dummy pile had problems she didn't have yesterday. Yesterday, with the throws from the left side, she lined every send to the pile and never needed to be handled once. Today, with the throws from the right side, she veered to Nate on the first send-out before she'd had a mark, and then veered to the fall on the first two of the three pile send-outs after marks. She handled fine the first two times to get her back on line, but on the third veer (after the second mark), it took three SWs before she sat. I don't know if I should be worried about her veering increasing from yesterday to today, but I don't think it's a good sign that her WSs deteriorated that way.

Tomorrow I plan to do another TTL from the left, and then the next day another from the right, hoping to get enough data points to understand the trend lines better. Maybe a more experienced trainer would already understand what's going on.
