Ok- I'll play.
Would anyone see an advantage in being on the left side of the dog as they go over 6 and then crossing as the dog lands to get to the weaves?
The only advantage I can see from not rear crossing 6 is that it pulls the dog further out from the weaves in order to help setup a better weave pole entrance. I see this as entirely unnecessary unless your dog struggles with on-side weaves.
From 10,11,12, if the handler stayed on the right.... would that cue the off course jump (that has no number on it?). What handling moves would take the off course jump out of the picture entirely for the dog so while they were taking off for 11 they'd only be seeing 12?
Entirely depends on the dog. And the handler. If the handler just stands in the middle of 9-10-11 to do the pinwheel without hauling
to get in front of 11- then yes, I think the off course is a strong likelihood. But it would be (as usual) entirely the handler's fault. The way I see it- as soon as the dog has committed to 10, the handler should be hustling over to the right wing on 11, indicating a slice. The handler needs to be pointing at 11 while shoulders are pointing at 12. It's just a slice at that point, and there shouldn't be a reason for the dog to want to take the off course. You might even support this with your off hand.
THe line from tunnel, #16, 17, 18... if the handler's plan is to stay on the dogs left as they come out the tunnel and go to 16... as the dog gets ready to take 16, FROM THE HANDLER POSITION, would the dog be more likely to guess the course continues to the left with the off course #4/#11 jump? Is there something the handler can do (have done?) as the dog exits the tunnel that takes the off course 4/11 out of the picture?
Again- I think this entirely depends on the dog. If the dog is very velcro, then it may want to turn into the handler. But in actuality- this setup is not much different from 10-11-12. It's just a slice. In fact, there is a perfectly straight line out of the tunnel, over 16, and onto 17. If one has put in the practice on slicing jumps- there shouldn't be an issue. Now, if you aren't fast enough and your dog is way ahead, then sure- there could be issues here. That's all part of knowing your dog (and how well you keep up with them). For my dog, she doesn't particularly rocket out of tunnels. So in sending her to the tunnel, I'd be sprinting to that 16 jump to ensure that I am at her side when she makes it to the 16. I'd just paint the line to 17, and move forward with the rear cross.
Is there something the handler could do to take the 4/11 out- well sure. The handler could
rear cross the tunnel entrance to put themselves on the right side of the dog. While an interesting thought- I posit that making the handler's line longer than the dog's line is a good way to have your dog end up way
ahead of you. I'm not sure this is a great move unless you are crazy fast (or your dog is crazy slow). IMHO, of course.
Is it better to push (be in our dog's way to block) the path of the dog to show them the direction? Or is it better to be able to attempt a handler move to show them where to go.
Totally dependent on the dog. Pimg responds to pushes way
better than pulling.
