19. Boerboel

Boerboels weigh between 120 and 200 pounds, but they often underestimate their strength. The Boerboel is brave and devoted to its owners because they were bred to protect families and hunt game in order to survive. With a name that means “farmer’s dog,” this breed is fiercely dedicated. They will protect their family at all costs, and when they sense danger, they may become vicious. The Boerboel can revert to a vicious survival mode when their human prey appears to be in danger. The American Kennel Club encourages caution, early socialization, and training for new dog owners.
