Snake Stopper or other snake repellant

[scogind]

I've had a couple of snakes get to the eggs over the years and every time he/she (who can tell?) was within 10-20ft of the coop. They don't feel like crawling very far after filling up on eggs I guess. But, ever since this little stray dog I call "Bingo" came around I haven't had any snake problems. My other 2 dogs just bark at them, but Bingo rushes in and kills them on the spot. He's strickly business when it comes to snakes.
