I know you have plenty of "pelts on your wall". If you haven't guessed, I'm Chuck M, the dog in question is Cinder out of Willow and Roy's Jag. Is your advice to create no go's by running force to pile until she no goes and then burn?
One additional piece of info. After Cinder no go'd in two consecutive MH tests in Fairbanks, I took her to the legal training area there. I though maybe it was the heat that caused the no go's. I ran about 15 consecutive blinds ranging from 100+ to 250 + yards hoping to get a no go and then burn. I never got one. In fact, I almost ran too many and gave her a heat stroke. Lucky I had an outdoor shower on the RV with cold water. Too bad Roy's not around in case he has some pertinent advice based on Jag. I never had this problem with Willow (mother) or Onyx (grandmother).
Sandy thinks Cinder can sense loss of confidence in me and there's nothing I can do about that since I don't know when or where this will happen again. It did happen again at Turnagain. As I stated, I reran the exact blinds later, and she got the long one with one handle and line the short one. She never has this problem in training. I believe she ran the exact test two years ago when she was 2 and had no problems.
I've signed up for the two HT's at Point M but am afraid the same will probably happen again.
