I do with George, but I have been getting faulted a lot this year at shows with it now that I am having to push him faster, some have been very close, but with a blink of an eye it can be missed because they don't stop,
One show I was at a lot of the running contacts were faulted and they were fast G7 medium dogs
our winter training is to get him to bring his head down without treats so to get it ever time , but with no pressure at him ,as more we focus on it the more he can pop it
