The Boerboel is a large, mastiff dog breed from South Africa, bred for the purpose of guarding the homestead. These dogs were often a first line of defense against predators and were valuable in tracking and holding down wounded game. Old farmers tell many tales of the strength, agility, and courage of their Boerboels.The Boerboel is a large, heavy mastiff breed. The height ranges from 60 to 70 cm (23 to 27 in) when fully grown (24 months), and the weight of an adult varies between 50 to 80 kg (110 to 175 lbs). For comparison purposes, a Boerboel is generally heavier than a Rottweiler or a Doberman, although the same weight, but not as tall as a Great Dane.Boerboels are an intelligent and energetic breed. If not provided with adequate stimulation, they will invent or discover ways to entertain themselves - ways that are often considered destructive by their owners. They are loyal and can be extremely protective of their family and territory. Obedience training is strongly recommended as they are a powerful and headstrong breed. Owners must socialize their boerboels when they are young by exposing them to unfamiliar adults, children, and animals, and to new situations. Prospective owners must recognize that owning a boerboel requires a significant commitment in time and energy as they must be well-trained and socialized in order to be happy members of the family. Boerboels are sensitive to their environment and their owners' moods - they cry and laugh right alongside you. They are quite charming when not being lazy, and will not hesitate to defend you to the death. This dog is the most protective dog breed that is not aggressive. The potential for aggression if not properly trained and socialized, combined with their intelligence, protective instincts, large size, physical strength, and sheer stubbornness, make the boerboel breed unsuitable for first-time or inexperienced dog owners. Boerboels require human companionship and structure. Owners must be able to control their dogs, through physical strength and social dominance, to prevent the breed's natural protectiveness from becoming aggression.
