aversion in training does not automatically = shutdown dog but it is very easy to do wrong, you should only learn about how to use aversion from a good certified trainer
I will say you donāt have too use aversion if you donāt want to, it is 100% possible to train without it. I personally donāt like using aversive training methods, I donāt think that it does any good but that isnāt the point I was trying to make
there is a lot of good information that is more common in the +R training community then in the balance one that I think is good for everyone to use. There is also a lot of bad information that is mostly in the balance training community unfortunately
