Before I do, let me say that you have the cutest dog in the world! I love that picture of her in your sig
.
The way we did it:
I would start out standing on the right side of the poles, with my left foot lined up with the second pole. With the dog behind me (I'd throw a treat backwards if I had to), I would simply stare at a spot on the ground on the left side of the gap between poles 1 & 2. Whenever Meg looked that way, click and throw the treat backwards so we could start again. She pretty quickly started to run through the gap. Once the entry was really confident, instead of throwing the treat behind, I'd treat between the second and third poles so she was basically doing the entry and the next pair. I believe the instructer calls it a "macaroni" (like the elbow shaped ones). Once that was confident, we'd work our way down the set, treating for each "elbow". Within about a week, Meg got to the point where she could do a set of six (all I have at home) with one treat at the end. She's gotten much more independant fairly quickly. I can be pretty much anywhere in relation to the poles and send her through (although now we are working on my being and the end and calling her through - that's harder!). She also had no issues her first time doing 12.
Like I said, that was the first time I've seen weave poles done like that, but I can say that the school I'm at now has many more dogs who are great on the weaves than the school I used to be at that did channels/v's. I'm really interested in seeing more about the 2x2 - they sound like they have a really good success rate as well.
