CJ, I've had several dogs that were bit by copperheads as well as rattle snakes, they all came through just fine. I had a border collie that was bit apprx 5-7 times, my dad was to poor at the time to go to a vet(I was a kid)he would melt 2 sticks of butter and the dog would drink it, within 24 hours he was at it again. Good luck, Cody
