Well the spin is what I'm going for, but for now I've started mainly with rollbacks using the fenceline as my pivot point (if that makes sense). Just doing a 180 reverse on the fenceline, with the front end coming inside.
I find it's really helping with her neck-reining training and making her, overall, better with moving off her hind end.
And thanks Sorrelhorse and nrhareiner. Apparently I've been doing it correctly :)
Although, it would really help you if you could explain some exercises for teaching them to follow their nose. And possible exercises for moving different parts of the body. I know what it is, and what you're talking about when you say it, but doing it is another story. And by exercises, I just mean thing I can work on with them, different tricks/techniques I can use and what cues or signals I should be giving.
Thanks a lot guys :)
