A great LGD will keep watch over your livestock at all times and should be friendly toward them, as it's their job to protect the herd or flock from any potential predators that may be lurking. Good LGD Breeds include the Great Pyrenees, which has been used as a livestock guardian for hundreds of years because of its excellent disposition and its natural guarding instincts. This dog can be extremely aggressive toward predators, but is also a wonderful companion to gentle and helpless small animals like chickens. The Maremma Sheep Dog is another option, which is very good with animals, particularly lambs, and offers protection against terrestrial and aerial predators. The Anatolian Shepherd is also a good choice, as it exhibits impressive speed and agility, making it perfect for defending against predators, and its natural protective instincts and intelligence allow it to guard livestock and poultry without much human direction or supervision.
