Guard dogs are an effective method to reduce predation on livestock.
Guard llamas and donkeys also appear to reduce losses but appear less effective than guard dogs. Llamas and donkeys are most effective in fenced pastures less than 300 acres. Raise guard dogs with sheep and treat them as working dogs. Introduce llamas and donkeys to sheep in small pens. They can be used to protect small or large flocks in fenced pastures, on open range and in feedlots.
