Doberman Pinscher
Doberman Pinschers are usually known for being police dogs, loyal companions of law enforcers, but that isn’t as common today as more breeds are capable of doing what they do. A little less dangerous than the dogs on this list, but still dangerous in general because they only tend to be very aggressive towards strangers than people they are familiar with, like their owners. There has only been one reported incident of an attack, and that was back in 2011, when a Doberman Pinscher killed its owner, an elderly woman.
