#5 Doberman Pinscher
Dobermans were bred to serve as personal guard dogs. This makes it clear why many consider them to be potentially dangerous and overly aggressive. Many individuals experience terror just by glancing at these dogs, which is normal.
Doberman Pinschers are now used as service dogs by the military and police. As a result, they have an aggressive reputation that is not entirely undeserved.
Dobermans may exhibit aggressive behavior toward strangers because of fear or a desire to defend their owners. They’re incredibly clever and trainable, though, and with the right handling, they can make excellent companion animals. Your Doberman needs to be socialized from an early age in order to learn how to act among strangers.
