At our last Euro-style agility class we were doing backwards threadles. It didn't always work out so well for me.
At the point where I took the fall, we are supposed to move (run) backwards, call the dog in to us then send them out over the jump that Beckett took coming towards me, then pull them through the two jumps and send them back out over the second jump. When it works it works beautifully but not this time.
Beckett did jump this course beautifully for the most part. It's really pretty amazing as in this class we were not allowed to use verbal cues only our body language and position tells the dog what to do. I can see in the video where Beckett knocked the bar that I hadn't given him any cue as to what he was supposed to do so he chose correctly to do the jump but wasn't really in a good position for the take-off.
Believe me, we ran this course again right after this and got through the whole thing. It felt awesome.
