Boerboel
These dogs might be scary, but not if you are the owner. They were meant to be watchdogs. They are tough, tall and scary. At first glance, you will surely run away from them. They can be easily trained though. They are self-assured and they are willing to fight when necessary. If you use them as guard dogs, you are assured that they can defend your family. You can also leave your house with confidence since you know they will fight off strangers who will try to break in. If you have kids though, you should never leave them unattended. These dogs tend to be aggressive even with kids at times.
