Land/water Doubles, Shore-handling Toolkit

Summary. At Cheltenham, with son Eric helping:
  • Series A, B, C. Poorman land/water doubles (both dogs)
  • Series D. Continued work on toolkit Tools #8 and #9 (Laddie)
Series A, B, C. Because Laddie has marooned on LTL retrieves at group training on marks comparable to ones where he no longer maroons in solo training, I asked Eric to come throw for us so that Laddie could develop fluency when a thrower is involved. As on previous days, we set up in three locations, and in each location, created a different set up for each dog. Today, all of the set-ups followed this design:
  • #1 (the memory bird): A tempting, open water mark thrown by me from a position marked by a stickman, using a duck. I would fire a pistol, throw the duck, then return to the dog to call for the second throw.
  • #2 (the go bird): A challenging mark thrown by Eric, using a white dummy. Eric would fire a pistol, then throw.
For Laddie, #1 was a non-cheating mark and #2 was always an LWL retrieve. Laddie had no difficulty with any of the doubles.

For Lumi, #1 was a long cheating mark that she was unlikely to cheat on, and #2 was an LWLW thru channel with dense debris for Series A, an LWLWLW for Series B, and an LWLW with the fall invisible from the SL for Series C. All of the #2 marks required significant handling, and Series B finally required me to call Lumi back to me, then walk her around to a closer point and send her from there. As soon as she had the dummy, I ran back to the original SL and she had no difficulty with her return and delivery.

An example that I think illustrates Lumi's current level was on Series B, #2. After Lumi crossed the strip of land between the two water segments, she was not visible to me for some time. The dummy was well on the far side of the channel and well to the right. If Lumi had wanted to run the bank, she would have crossed straight over to the far shore, then run the bank to the dummy. She also could have done that on the return. If she had done it on the way out, I wouldn't have been able to see it or try to handle her until she was nearly across.

But as I watched the visible area of the channel after Lumi disappeared behind the embankment, she finally came back into view. I was pleased to see that she was on a line from her water entry point directly to the dummy. I was again pleased when she arrived at the far shore, picked up the dummy, and entered the water immediately, swimming back the way she'd come, directly toward me, despite the bank running option and also a point she could have diverted to on the way back. She then crossed the strip of land and again entered the water on a direct line back to me, despite bank running options on both sides of the pond she was entering.

Lumi seems to be gaining a nice understanding of how to stay on a straight route in the presence of cheating opportunities.

Series D. For Laddies work on Tool #8, Over-LTW-W, combined with Tool #9, Over-WTL-W, I placed a lining pole on each side of the pond we used for Lumi's swim-by a few days ago, and where we'll also do Laddie's swim-by. I then had him make four crossings, alternating between left to right and right to left. For each crossing:
  1. I placed Laddie in a sit at one of the lining poles with a dummy between him and the water.
  2. I walked around to the other side, stopping 6' before I got to the lining pole on that side.
  3. I cued Over verbally and visually.
  4. Laddie pounced on the dummy, then quickly entered the water and began swimming toward me.
  5. I repeatedly cued Over as he was swimming, gradually influencing him to veer away from me and toward the other lining pole.
  6. When he came out of the water near the lining pole, I cued Sit, then cheered and ran over to engage him in play.
Hopefully in the next few sessions, I'll be able to move further and further from the target lining pole, eventually holding my position at the end of the channel and letting Laddie swim by me from one pole to the other. Next would be to remove the poles, and finally backchain the earlier steps of a full swim-by.
