I think to be fair we should perhaps focus on the well meaning part of the op's intention. As I read it he's debunking stunguns as treatment for snakebite. I dont think it was kids vs dogs.
That said, where I live I have the delightful Puff Adder everywhere I detect....they play dead and wont move out the way (yet are very fast strikers when need be) move at about 1/2 walking pace and normally kill you if you are 6 hours from help. Lets face it, it adds a little sizzle to detecting - it's all good sport!
To be honest though I spend as much time in nature as possible so my movement detection, animal/ human/ insect /tracking, weather spotting, tree /plant identification is pretty much on point.
