I ran a variety of tests this summer. Some AKC Senior, some Master, and some HRC Finished. Some were recorded by my wife with video-cam from behind the line. Some have a lot of vocalization going on as the dog is coming to the line and preparing to run. Some comes from the judges talking to bird stations via radio and some from the judges talking to handlers in the last holding blind, and to late comers who want to view the test. While my dog was not distracted, I must confess that I was to some degree distracted.
It is unreasonable to expect that when you are called to the line, that until you call for birds that it remains somewhat quiet? When we are hunting it is frequently highly noisey, but that is hunting, not testing.
I expect my dog to remain quiet and steady. Why not everyone else? JD
