On our small one acre farm we have 2 dwarf goats, 3 lambs and 9 chickens. We plan to add a few more sheep next year. Our English Setter is awesome with all of them but she is getting on in age and probably won't be with us for more than another 3 - 5 years. We would like to get a new dog or puppy so that she has the time and energy to help train the newbie. What breed will be good at protecting along with having herding instincts and yet not want to eat my free range chickens. I have been looking at Healers, Border Collies and Aussies but I'm uncertain how they will be with my hens. We have hot summers and cold winters here in Utah. I want a dog that will stay outside day and night to protect. The only downside to my Abby dog is that she has always been an inside dog and refuses to be out for long periods of time. Any advice on a new breed or mixed breed?
