Doberman Pinscher
Doberman Pinschers have a history of being used in the military thanks to their aggression. In the ‘70s, this dog breed was popular. However, there was also a rise in dog bites back then. Horror stories say that many dogs attacked their owners for seemingly no reason. While the cases have gone down as of late, things can get ugly when a Doberman turns on you. Insurance companies remain wary of them.
German Shepherd
German Shepherds are known for their loyalty, but they are also smart and obedient dogs. They are intelligent and aggressive, which makes them ideal for police use. Insurance companies know all about this, which is why you might want to think twice about getting one. Even though they can still be good family dogs, these large and strong animals might turn on the wrong person by mistake!
