Let me clarify. I totally understand about not using them at the line. That's just common sense. The judges, gallery, and pro's running multiple dogs would be acting like they'd just been to the farewell concert of The Who if full poppers were used at the line. I'm only talking about in the field with guns clamped into stands pointing in a safe direction. Sit only means sit if dogs have been exposed to the distractions they're going to encounter like louder gunfire. I've seen staked out dogs at training sessions barely blink with primers but I've seen those same dogs darn near try to yank the stakes out of the ground when full popper loads went off from 50-350 yards away.
