A really well-trained agility team can perform any sequence in a variety of ways. While one technique might turn out to be optimal, advanced teams should have an arsenal of moves committed to reflex. First, it keeps the dog guessing and focused on the handler. Secondly, you never know when you might need to do something different than planned, including having someone else run your dog like I did in Monroe last weekend.
To this end, after my students have more or less mastered Handling Fundamentals, I get them handling each sequence in 2 or 3 ways. So far, so good. But this video, by Steve Schwarz, Agility Nerd, tops all I've ever seen. With only 2 jumps and a tunnel, he musters 11 different ways to send his border collie over the back side of both jumps. It also demonstrates clearly the PUSH and the PULL. It's called Double Back Side Exercise and can be practiced in a tiny space. The tunnel can be replaced with a see-saw, the bar jumps by other jumps.
I hope others will set this up and let me know how it works. WARNING: Steve makes everything look effortless. When I get around to setting it up for myself, I plan to video myself, perhaps getting a laugh or two. I do so wish to be funny. :-)
Upwards and onward!
