The real question is why so many amateurs and pros still accept risks, brutality and poor results when the simple, effective solution has existed since 1986. It's a tape, now also a CD, that desensitizes dogs to gunfire. Based on a study suggesting that students learn better while listening to music with a beat that corresponds to their own heart rate, original music was written for dogs. Segment one is music only. In following segments, gunfire is added and gradually escalates from a few pops weaker than BB guns to many shotgun blasts as loud as the music. After that, the music diminishes with each segment until only the loud shooting remains. Throughout, the volume setting stays at a level that makes the gunfire in the final segments as loud as nearby shotgunning. I tested the original prototype on an otherwise incorrigibly gun-shy Lab who had been punished for noise sensitivity before coming to me. He found the music calming, accepted the gradually increasing gunfire as part of the music and by the end was desensitized into thinking shotguns are as soothing as music. It works.
