Both of those are on the temperament test. They are suppose to let a friendly stranger approach, they are suppose to not react to a friendly stranger petting them, and they should hold their ground if a loud obnoxious person approaches. I'm not sure what reaction would cause them to fail with a gunshot, the gun is fired three times 15 ft away from them. Both of mine just looked in the direction of the shots, my male was slightly more alert and focused on the "shooter". All of the dogs that tested and made if that far reacted pretty much the same way.
