Doberman Pinschers

First discovered by a German tax collector, Friedrich Louis Dobermann, in 1890, the Doberman Pinschers are mid-sized domestic dogs that have gained wide recognition as being too protective and caring for the youngster with whom they were nurtured.

While the Doberman breed is lively and robust, making them a perfect choice as a family security dog, nonetheless, their overprotectiveness at times becomes an obstacle. This four-legged companion usually requires a lot of training, socializing, and exercising and may become impatient and aggressive when stimulated in their protective mode.
