A more recent study published in the journal Applied Animal Behavior Science in 2014 reported that breed was not a good predictor of aggressiveness towards humans. Dogs purchased from breeders were less aggressive towards humans than dogs purchased from pet shops or obtained from rescues. Dogs that had attended puppy training classes were less aggressive towards humans. Spayed female dogs were less likely to be aggressive towards humans in all contexts. The 2014 study did not evaluate aggression towards other dogs.
