We raise sheep and have had good luck with our gaurd llamas. They are very easy to care for. A gelded male is the best choice. We raise sheep and our farm borders the Charles River where coyotes are plenty. Over the winter we lost one of our llamas to old age and when we were a llama down the coyotes got one of our goats. Needles to say we got another llama and I sleep a lot better now. Good luck!
