I will certainly be on the hunt for the VA ones as well... And will my dog hunting a lot in PA, the less venomous ones up there, the less I have to worry about her being bit again.

I did check on snake breaking classes with the vet today. He said snake bites are so rare on dogs in VA he doesn't know of any in the area. He did say they came out with a new "vaccine" for rattle snake venom you actually can give to a dog. He wasn't sure if it would work for copperheads and didn't know of any vets in my area who had been using it yet. He said it was a western thing mostly.
