The Boerboel, also known as the South African Mastiff, is a large and powerful breed that was originally bred as a farm dog. They are known for their loyalty, protectiveness, and bravery, and make excellent guard dogs. Boerboels are also very intelligent and trainable, but they require an experienced owner who can handle their size and strength. With proper training and socialization, Boerboels can be loving and affectionate family pets.
