I guess the 'wrong direction the adivice has taken' is aimed at me. Mind you, I never said to roll the pup. I said to stop yelling 'ouch' and take some charge. And yes, grabbing her by the scruff of the neck is one way that can easily be accomplished. If the poster has issues with that, then I really think that the pup will grow over her head anyway in due time (when things will be so much harder to correct) I don't think it will take a lot of firmer behavior to make a point with this pup. I do not read dominance, but opportunity. Naturally, everyone is limited by their own actions when it comes to what they can do with dogs. I mostly get the total nutcases, created by many many loving hands that were never used to give direction, and yes, some created by brutality, but a vast minority.
Nobody ever advised to be mean. But rather to set clear boundaries and limitations on what is or what is not allowed. I also adviced seeking a group to train the pup with, since internet diagnosis is a dangerous animal.
Sorry that you have taken issue with it, unless I misunderstood that, in which case I apologize.
