Honestly, that is difficult! I would hands down have a dog always. That being said, I put goat down because I don't really consider a dog to be a herd animal; it's a necessity! I don't have one right now but hope to get another Aussie soon. I had two Aussies (both passed on )that were just the best at keeping the yard free from predators plus they were great with all of our animals. Our older dog, Max, always kept a close eye on the chickens (especially the young ones) to make sure they were okay.
