Played with Bud tonight using my cap gun with out the caps but it still makes a noise, I thot it would scare him but he wanted to smell it more than be worried about it. I walked all around him constantly "shooting" and he never moved, I even laid my arm across his back and shot and he just stood there, so my next object was a noodle like people use in their pool , amazingly that didnt bother him either, but let the neighbor walk around up the drive way and his head is up and looking....hmmm, he can be such a goober!
