I assume we are talking about Central Eastern United States. Generally if you have no standing water and no rock piles you will seldom find snakes on your property. Also I never met a dog that didn't go straight to snakes, hidden or sunning. That said, erickonphoenix is very correct, you need to learn to identify them. Copper heads, water moccasin's are IMO to be avoided as I have found them aggressive. Eastern Diamondback's can be territorial but don't want human contact. I have spent millions of hours on a farm, hunting, back packing and mountain biking and I honestly don't remember more that 10 encounters with venomous snakes. A couple hundred black snakes and quite a number of water snakes. A snake bite kit is reasonable but there is a lot of home work on what kit and shelf life.
For a real kick I have been to this once and IMO these folks are nutz.
