Considering that she is talking about what she learnt in a school, I find the example to be extremely relevant to the issue.
Lesson horses ridden all day long by novices sometimes DO get unresponsive to leg aids- I don't see the difference your trying to push here. I didn't say you were uncorrect (In fact, I didn't address what you said to do, I addressed the main post, referring to the three choices she has been taught- not you specifically).
Please re-read my post- what I stated is that if you hold horses in, it is an attempt to avoid all mistakes. I'm saying, give them a cue and then give them a chance to listen to it, instead of doing the work for them.
Swuezo, I also didn't pick on you about your reins. Look at this logically- you stated one opinion, not the way you ride. Hence, I have no way to critisize you specifically. Sorry to snark, I'm just really tired of people on here skimming my posts and assuming things or assuming I am talking to or about them- it's not the case. If I were, I would have clearly stated your name or inserted a quote. Your style of riding has nothing to do with ym advice for someone else in this case. YOU are not the one asking the question- so there is no need to assume that I was directing my advice or opinion to you. That would be a waste of time here.
As a note just to you: I don't drive my horses at a walk. I ask for a walk, and they walk until they are directed to stop or perform a transition. Maybe it's a western thing. We don't do that- we ask and then reward. Pushing a horse constantly is usually visable, and isn't the best sign of training where I'm from.
