In a recent study, aggression was divided into four categories: aggression directed at strangers, owner, other strange dogs and rivalry with other household dogs. This study found that the Doberman Pinscher ranked relatively high on stranger-directed aggression (behind the Dachshund and chihuahua), but extremely low on owner-directed aggression. The Doberman Pinscher ranked as average on dog-directed aggression and dog rivalry. Looking only at bites and attempted bites, Doberman Pinschers rank as far less aggressive towards humans, and show less aggression than many breeds without a reputation (e.g., Cocker Spaniel, Border Collie and Great Dane). This study concluded that aggression has a genetic basis, that the Doberman shows a distinctive pattern of aggression depending on the situation, and that contemporary Doberman Pinschers are not an aggressive breed overall.
biologist Stanley Coren ranks the Doberman as the 5th most intelligent dog in the category of obedience command training in his book The Intelligence of Dogs. Additionally, in two studies, Hart and Hart (1985) ranked the Doberman Pinscher first in this category, and Tortora (1980) gave the Doberman the highest rank in trainability, as does Howe. Although the methods of evaluation differ, these studies consistently show that the Doberman Pinscher, along with the Border Collie, German Shepherd and Standard Poodle, is one of the most trainable breeds of dog.
