Could it be that we are confused by what part of the performance is learned and what part is taught. How did you teach your dog to be so intense that he quivers when being whoaed? Mine only appear that way when on an instinctive point. Giving a command of any kind to them at that point only tends to lessen the intensity of the point. The only time I want to speak to my dog on point is when his body language tells me he is fixing to break. A whoa then tells him you better not move a muscle until I release you and the learned "whoa command" prevents him from making a mistake while he continues to hold an instinctive point. What part, or point, am I missing here?
