In the video below, I demonstrate some of the steps involved in increasing the distance from which you can handle the wrap to the tunnel. I begin with Libby at the "good start" position. Since she doesn't send to the tunnel the first time, I move in with her as needed. With a less experienced dog, I would move in even closer to tunnel. However, since I am working on sending to the tunnel, I would not get closer than four or five feet to the tunnel entrance. As the dog gains confidence, I can then work my way back to the black distance line.
When I began writing this post, I thought there were only two components involved in achieving the distance needed to successfully complete this exercise beginning from "the goal" without crossing the purple distance line: send distance and lateral distance. As I worked toward "the goal" with Belle, I discovered being able to send her from this spot also involves getting her over jumps A & B and then being able to turn her to the right after C/#1.
(P.S. 03/21/11. As you watch the video notice how much more successful we are when I remain in motion rather than coming to a standstill and depending upon arm movement to send the dogs.)
I was pleased with how well the dogs did. Dusty did a nice job with a bit of increased send distance, and Belle was able to handle both the increased send and lateral distance challenges. I think that if obstacles #1-#3 had been the only obstacles on the field, Belle and I could have completed this exercise from way out by "the goal." (I wish I would have thought to try that before tearing down this course.) When I set up this course again, I will work on the exercise below. Once we can do that, I'll see if we can get that pesky wrap into the tunnel.
