Aside to an occasional copperhead,non-venomous snakes are much more aggressive by comparison. The only thing that give's rise to more old wives tales and tall tales in general than coyotes is snakes. The best thing you can do when living with venomous snakes is educate yourself. First priority is lean to identify each venomous snake in your area. Don't even try learning each species of non-venomous,it's a waste of time and require's 100 fold the experience and education required to identify the one's that are venomous. Not trying to discredit you,more so to get your education started. You said you saw a coral on a recent visit. Tell me how you knew for certain that's what is was. It's the easiest of all to identify but 90% of sightings are mistaken identity. We can come back and spend time on identifying all of them if you want to but for now we go to the second best thing for staying safe. Most any naturally aggressive breed of dog can be trained to find and bay snakes. Here's where the decision can get problematic. Eventhough many lap dogs can be trained as great snake finders,I highly recommend starting the relationship from day one looking to the dog as a tool and having it live outdoors when weather allows. Small to medium size terriers excel unless they need to defend against 4 legged intruders. I'd 2 to 1 rather have a small and alert dog that sound's the alarm then let's me handle it than a pit that chew's my long lost friend's leg off before I can stop it. Do those two things plus common sense like mowing and keeping trash to minimun and the odds are stacked overwhelmingly in you favor. I'll be happy to spend all the time you like on this if you ask.
