Out of 21 assessments, only 4 dogs
showed any form of
aggression towards humans, and some, like dog # 31 (whose assessment is pictured below),
showed no
aggression whatsoever.»
Most of our dog breeds have some form of
aggression in them, since they needed different forms of
aggression to do their work: terriers are often aggressive
towards other dogs and animals — they were and are fighters, the man working dogs imprint
humans as being of their same species so they
show the same kind of
aggression that they
show towards other dogs, the sight hounds were bred to be killers of game and sometimes other canines, the mastiffs were bred to take down large game and guard property, the flock guards were bred to be aggressive
towards canines, the hounds were bred to be aggressive
towards furred animals, some of the pointers were bred to be able to guard the hunter's game, etc., etc..
A higher proportion of dachshunds, Chihuahuas and Jack Russell terriers
showed serious
aggression to
humans, whereas serious
aggression towards unfamiliar dogs was reported in more than 20 % of the Akitas, Jack Russell terriers and those dogs classified as pit bull terriers.
