The "rack the pump" guys must have very quiet, empty, and small houses. In my house, the clocks tick, the floors squeak, the HVAC system clicks and clacks on and off, the refrigerator's compressor goes on and off, and the dog would be barking and howling. Chances are that if the dog is howling like that, I'll trigger the alarm system. Also, I keep the shotgun well maintained and lubricated. I have my doubts that putting in a round is going make the BG zero in on my position. More likely he'll be trying to figure out where the dog is and what kind. The alarm is more likely to make him run than the sound of the pump. And if he runs in the wrong direction - like into the bedroom where we've taken cover - I'll have a round racked and ready.
