He doesn't "weave" he just got macaroni weaves together and he will walk back and forth between them now. No speed, no pressure, supervised by an agility trainer. It's all clicker trained and just a flat command for him, currently. And this has been worked on all of three times, it is certainly not causing a lack of range of motion in his wrist when there's no impact, and to imply that it is, is completely insulting. Eta; there is a huge difference between running down open weaves (which he had been doing up until that post!)/walking in and out using reverse luring down a 6 set, and a finished "weave" which is not something we could have accomplished by now that would injure him if we tried. Which we haven't. Our trainer recommends to get motion down starting at 8/9 months and leave it until a year then start building drive and speed to get the real "weave" motion down.
