The Boerboel [ˈbuːrbul], is a large, mastiff-type dog breed from South Africa and is bred for the purpose of guarding the homestead and working the farm. They are one of the most powerful dog breeds in the world and have a bite force of 985 psi.Boerboel breeding is both a hobby and an industry in South Africa. These dogs are now exported from South Africa to other parts of the world. Due to its use as a farm dog which brought it into conflict with large African predators such as lions, the Boerboel has been artificially selected for ability to protect themselves and others.
