I'm not going to try hunt all of the snakes down on 320 acres in the flint hills. You are welcome to come out and give it a try. There is rattlesnake venom vaccines for dogs, cost $25 at your local vet.Dogs, although not good, don't react as seriously to rattlesnake venom as humans.
Don't blame you, but - no thanks, not that enamored with them to overtly seek them out...run across them "accidentally" enough
Many a good gundog is lost annually in the various bird seasons to the fanged ones--despite "snake training."
