Thats great that it took care of the rat problem. That is what those dogs are bred for. I am sure it is much happier killing rats than being some overly groomed purse dog.A few years ago, my mom adopted an insane terrier that looks like it hails from Chernobyl. We realized that he has taken care of our rat problem when we found some eggs under the chicken house. They were only there for a few days and had not been touched. In years past, we've noticed rats moving around under their house and I'd find them poking around in the pen after dark. One summer, I was having such fun sitting at an open window with my .22, plugging rats as they popped out of their hole in the back garden. Haven't seen a single one back there. Haven't seen any scrounging around for seed under the bird feeders. That was another good sniping spot. While I despise the dog, I'm pleased that we don't have rats any more.
