As I get close enough to the jump, I turn to face her and bring up my right arm. The initial step of this is to keep the arm down near me to call her in to me. Once she gets close, and I am in position - blocking half the jump, basically - I lift my right arm give her the cue to jump. It's a bit of an arm motion, up and back, with the shoulder somewhat involved. It is an obvious, irrefutable cue to jump. My positioning blocking half the jump tells the dog to wrap around me, and thus the jump wing.
The dog lands and I pick her up on the left side and move on. Because this cue ALWAYS means to wrap the jump wing (me), it is ALWAYS a pull-through maneuver, and she should never take the other jump when I do this. So far in training, she is doing this very well. Once she understands the cue, and I get my positioning right every time, I should be able to cue it and begin running immediately again.
Previously wraps and pull-through's have been difficult with Seri, not because she won't do them, but because she has a lot of trouble keeping the bars up and turning tightly. These 2 handling styles (new to me, but I certainly did not create them) seem to help both these issues tremendously, and I have some hope for our future!
