Scott, my dad was from the Missouri Ozarks, and yes, the cottonmouth is more aggressive than any snake I've ever seen. There's a small stream called Swan Creek, which empties into the White River at Forsyth, not far from Branson. There were plenty of water mocassains farther up the stream and they could be pretty aggressive. My mom was a tough Montana girl and she was afraid of going up there. Interesting comments on your father's experiences with the bad guy. I was a police officer for a brief time in Orange County, in the late 70's, and I recall stories such as this, especially after officers started using the Wondernines (hi capacity 9mm pistols). My dad was a career homicide detective with SPD and I've heard incredible stories of people shot up badly but exhibiting superhuman strength, not only through substance abuse, but also simple adrenaline. I recall one case where a guy was shot point-blank in the chest with a 12ga with buckshot and ran an entire city block before collasping. Your point is well taken.
Pieter, good comments. My dogs do NOT know enough to stay away from snakes. you can have a bird dog "snake trained", which is fairly common in the southern states where there are more snakes.
This is accomplished with a defanged rattler and e-collar. I understand it has a fairly high success rate, for those dogs which do not sprint right into one before being able to hear or sense it. I have a hunting pal who had his dog snake-broke with this method while he was living in Texas. Despite this, his dog was bitten on the nose in Robinson Canyon a couple of years back. He blundered into the rattler without having seen or smelled it and the snake didn't buzz him. So, it works, at least some of the time, and bird dogs being what they are - bold and aggressive, don't always do what they're supposed to do. I'm thinking about hunting mearns quail is Arizona next spring, and if I do I'm thinking strongly of having my younger setter snake-trained. As for not being able to be in a position to defend my dog with a handgun, well, that's just not true for me. I've been in a tight spot or two where a snake buzzed us and I was able to grab my dog and steer him away before he got into touble, but if I was more than ten seconds slower it might have been different. I could have just as easily shot the snake.
