Livestock guardian dog

The use of dogs in protecting livestock originated over 2,000 years ago,[4] with their use being recorded as early as 150 BC in Rome.[5] Both Aristotle's History of Animals and Virgil's Georgics mention the use of livestock guardian dogs by the Molossians in the ancient region of Epirus.[6][7]

The dogs are introduced to livestock as puppies so they "imprint" on the animals. Experts recommend that the pups begin living with the herd at 4 to 5 weeks of age.[1] This imprinting is thought to be largely olfactory and occurs between 3 and 16 weeks of age. Training requires regular daily handling and management, preferably from birth. A guardian dog is not considered reliable until it is at least 2 years of age. Until that time, supervision, guidance, and correction are needed to teach the dog the skills and rules it needs to do its job. Having older dogs that assist in training younger dogs streamlines this process considerably.

Trials are underway to protect penguins with LGDs.[8]

A "wolf-collar", commonly used as a neck-protection by LGDs against predators

In Namibia in Southwest Africa, Anatolians are used to guard goat herds from cheetahs, and are typically imprinted between 7 and 8 weeks of age. Before use of dogs was implemented, impoverished Namibian farmers often came into conflict with predatory cheetahs; now, Anatolians usually are able to drive off cheetahs with their barking and displays of aggression.[9]

The three qualities most sought after in LGDs are trustworthiness, attentiveness, and protectiveness; trustworthy in that they do not roam off and are not aggressive with the livestock, attentive in that they are situationally aware of threats by predators, and protective in that they attempt to drive off predators. Dogs, being social creatures with differing personalities, take on different roles with the herd and among themselves; most stick close to the livestock, others tend to follow the shepherd or rancher when one is present, and some drift away from the livestock. These differing roles are often complementary in terms of protecting livestock, and experienced ranchers and shepherds sometimes encourage these differences by adjustments in socialization technique so as to increase the effectiveness of their group of dogs in meeting specific predator threats. LGDs that follow the livestock closest assure that a guard dog is on hand if a predator attacks, while LGDs that patrol at the edges of a flock or herd are in a position to keep would-be attackers at a safe distance from livestock. Those dogs that are more attentive tend to alert those that are more passive, but perhaps also more trustworthy or less aggressive with the livestock.

At least two dogs may be placed with a flock or herd, depending on its size, the type of predators, their number, and the intensity of predation. If predators are scarce, one dog may be adequate, though most operations usually require at least two dogs. Large operations (particularly range operations) and heavy predator loads require more dogs. Male and female LGDs have proved to be equally effective in protecting of livestock.

While LGDs have been known to fight to the death with predators, in most cases, predator attacks are prevented by a display of aggressiveness. LGDs are known to drive off predators for which physically they would be no match, such as bears and even lions. With the reintroduction of predators into natural habitats in Europe and North America, environmentalists have come to appreciate LGDs because they allow sheep and cattle farming to coexist with predators in the same or nearby habitats. Unlike trapping and poisoning, LGDs seldom kill predators; instead, their aggressive behaviors tend to condition predators to seek unguarded (thus, nonfarm animal) prey. For instance, in Italy's Gran Sasso National Park, where LGDs and wolves have coexisted for centuries, older, more experienced wolves seem to "know" the LGDs and leave their flocks alone.

Many breeds of LGDs are little known outside of the regions where they are still worked. Nevertheless, some breeds are known to display traits advantageous to guarding livestock. Some specialist LGD breeds include:
