Although pit bulls, German shepherds, chow chows, Rottweilers and dobermans frequently are considered the most aggressive breeds of dogs, any dog of any breed can be aggressive. Research shows that training and socialization is more important than breed in predicting aggression, reports the Smithsonian Institution.

According to the Smithsonian, researchers discovered that a lack of puppy socialization and obedience training is likely to result in an aggressive dog. Dominance-based training methods also are linked to increased aggressive behaviors. In addition to the breeds already mentioned, insurance agencies often consider Great Danes, Presa Canarios, akitas, Alaskan malamutes, Siberian huskies and wolf hybrids to be dangerous breeds. Researchers advise training a dog early and well to prevent aggression issues.
