Back the topic of dogs, is it not possible to train dogs to NOT attack snakes. I mean I trained my border collie over years (sure he was a bc, they're smart) to sit and stay and down with hand signals. I am 100% confident that if he were still around (no he was not killed by a snake) he would not hesitate to listen to me and come instead of fighting with a snake.
I know it is a stuff up when something you love comes into contact with a deadly reptile, but perhaps there is some sort of solution besides letting them kill each other.
