To me, it's a change in mind set. I didn't go cold turkey, but slowly phased out corrections, still believing they were needed sometimes. But the more I train Sienna and see the effects of even very mild corrections and stress, the more I realize that it's not needed, and it's all in my head. At least, with her. I still use aversives in the form of pressure, NRMs or "ah ah, leave it" type things as well, but I don't see the relationship as me vs. the dog anymore.
I was having some fetch issues recently that really brought home to me the difference between a command and a cue. I'm planning to write a blog post about it, but basically I was using "get it" to mean "please bring me the dumbbell now". Working through this problem (tall grass, short dumbbell, dog who thinks if she can't see it, it isn't there, but really, really wants to do what I ask so gets crazy stressed when she thinks she can't) made me realize that what "get it" SHOULD mean is "you now have permission to go get that dumbbell!"
In other words, I'm not telling or even asking the dog to do something anymore. I'm giving her permission to do the thing she really, really wants to do. So the first step in teaching the behavior is to get the dog to really, really want to do it.
Command vs cues - are like night and day to me now.
