You wouldn’t want to run into a vicious Boerboel in the dead of night. The Boerboel is a South African Mastiff that was bred in order to help protect family homes and farmland. As such the Boerboel is a large breed that is attentive and capable of dealing out damage to anyone it deems a threat. Boerboels are known for being fiercely loyal while also being strong enough to take out wild game almost on their own. As is the case with any large and aggressive dog, poor training can sour the breed and turn them into a nightmare to deal with. If you want to own a Boerboel then you need to ensure that its natural aggressiveness is finely tuned with professional training.
