I've had my weaves separated into 2 sets of 6 for quite a while to practice various entrances and exits and cross-in-fronts and -behinds. Put them all back together into the standard 12 in the middle of the lawn the other day.
My sister, sitting in the hot tub with me, said "Those are a lot of weave poles." I said it's just the normal set. Then I got curious--Tika was bringing her Toy to me at that time for tossing and tugging--so when I gained control of the toy, I pointed my arm in the general direction of the weaves--which were pointing straight away from us, starting about 20 feet away, and said "Weave!"
Tika charged over to the poles, made her entrance, wove speedily all the way through, and bounced on the thrown Toy with well-earned delight when she finished. What a good girl!
And what a good trainer, to have taught the dog that doing all that hard stuff is just another fun game!
