I use the V or weave a matics everyboy at our training facility uses them there are channel weaves there but they are rarely used.
We use toys thrown on the ground also and with some dogs food in a target at the end or their handler thows a throw tube with food in it , it all depends on what the dogs motivator is, at first they are slanted and you have an open channel, you gradually make them upright and rigid as the dog progresses, we preload and use opposition reflex and every dog there independently drives hard and fast through the weaves when their done with beginner class or they have to retake beginner, independent weave poles is a prerequisite to move to the intermediate class.
We actually replace a lot of broken poles.
The training poles are slightly shorter to allow for opposition reflex with the leash not getting tangled. I discovered this after hubby built and fabbed me weave o matics to AKC regulations for home and my leash was getting tangled.
Nobody prods, or drags, steps in we don't use props such as wires or gates either, total drive and motivation. Okay there is this one girl...................
Now some of us have rhythym moves, I have had several comments lately on how I run at the weave poles. Video evidene proves I have started to stutter step in rythym with her at the poles a lot, LOL. It looks like I am running an obstacle course with tires in it!
I have been working on getting away from this and leaving her in the poles so I guess I did have a crutch I didn't even notice I had.
