It didn't even yelp! At 30 yards I'm sure I'd have gotten some decent penetration even if I was using light loads. We've stung dogs before and had them yelp and yip for a long while, all while making tracks, but this one was quite. Either way, He's an educated dog now. Educated to roads, and educated to "things that go Boom." He still don't know calls yet though. Maybe we'll go make some noise in that area next weekend
