Doberman Pinschers are fiercely loyal and loving toward their chosen people. They’re also one of the smartest breeds around. Bred to be guard dogs, careless breeding in the past has given these dogs a problematic reputation. But if do your research and due diligence before you adopt one and are careful to work with reputable organizations, your Doberman should be loving, reliable, and protective. Many also work in the military and law enforcement.
