English Shepherd female that is not neutered. She will be reared in the barn. When Lucy nears retirement age her backup will be another male German Pointer. I see good balance with having at least one dog that will give bad guys a little chase and at least one dog that hangs back with stock. The Pointers are proven to penetrate fence quickly as needed so predator does not use fencing against dogs. I was considering get a large breed LGD although only threats better dealt with by large size are also kept out by the hotwire. The speed and smarts more important if bigger dogs already excluded by fencing.
