Are ES car-chasers like say Shelties? We live at a crossroads so I am concerned about that. Would an intruder be reluctant to proceed against an ES versus a larger dog? We had an middle-of-the-night visitor once. We have dairy cows, sheep, chickens and calves. I don't want a dog that will bite first and then bark so to speak. It gives me a sense of security when I am out working. I have thought about LGD but we haven't had a predator problem so don't know if that is best or not. Does anyone know of any breeders? What has your experience been with them? What is the cost of getting an ES puppy?
