Livestock gaurdian's are essential for keeping the sheep, and goats safe. They protect from preditors, both flying (eagles, hawks), and the four legged type (cyototes, wolves, and bear). Elliot, the gelded llama, takes his job very seriously and will sound the alert when anything unusual is going on. Three dogs, also, stay with the sheep. They are a mix of Great Pyrenees, Akbash, Anatolian shepherd, and just a bit of Newfoundland. They work well together.
