A livestock guarian dog (LGD) is a domesticated canine used to defend livestock against predators. LGDs are also commonly referred to as sheepdogs since they most often have guarded flocks of sheep, but most are capable of guarding other species of livestock. Unlike a herding dog such as the border collie, an LGD does not control the movement of the flock with aggressive or predatory actions causing bunching. Instead, LGDs tend to blend into the flock and generally ignore the individual animals in favor of keeping an eye out for potential threats. While bunching behavior is observed, it is the livestock that tend to bunch around the guarding dogs, especially on open range when predators are near.
