Honestly, I disregard so much of the step-by-step teaching even in agility classes. They use a LOT of food targets at the end of obstacles to get the dog to drive through (or over) obstacles. Didn't work for me with either dog. Kylie didn't like the food, didn't like the instructor that close, and wasn't going to eat off the sandy ground, anyway. Molly does not need encouragement to drive more toward any danged thing. Teaching 2o2o when I needed it with Kylie as a separate cue and without the target worked fine, and it SEEMS to have worked for Molly. If it doesn't, I'll back up and try something else.
It's at the point now, though, where even in class, they just pick up the target and move when Molly is running. They know I don't use it, they know she's doesn't need it, and thankfully they're pretty willing to let me steer my own ship.
I'm teaching Molly weaves 2x2, but how I taught Kylie was basically a strange combination of luring, sharping, and a tiny bit of 2x2. I'm pretty sure my instructor would fall over and faint if she realized how I taught them, in spite of having a dog who weaves better than any novice dog in our club, and better and more reliably than many of the elite dogs. I don't know why it worked. I don't know what to call the method. I couldn't explain it again if my life depended on it. But it worked.
And yeah, I don't read instruction manuals, either. Just give me the thing and I'll poke at it for a while and figure it out. I know what it's supposed to look like/do. Good enough to get there.
