Most and Least Aggressive Dogs
It turns out bigger might really be better after all. According to a study conducted by researchers Deborah Duffy and James Serpell of the University of Pennsylvania’s Center for the Interaction of Animals and Society, and Yuying Hsu of the National Taiwan Normal University, it seems that the smaller the dog, the more snap.
The researchers gathered data from multiple dog clubs, as well as an extensive online survey which asked owners to report on whether or not their dog nips, or tries to attack, unfamiliar (stranger) humans, owners, or other dogs, including whether or not their dog exhibits any rivalry toward other canines in general.
Ranking in the top ten most aggressive were Dachshunds coming in first; followed by the Chihuahua, which is noted to often snaps at its owners, strangers and other dogs; the Jack Russell terrier; the Akita; the Australian cattle dog; the pit bull; the beagle; the English springer spaniel; the border collie; and the German shepherd.
Among the least aggressive breeds were the Basset hound, golden retriever, Labradors, Siberian husky and greyhound.
Canine aggression studies based solely on reported attacks are often skewed because while most bites from small dogs aren’t serious, bites from large dogs often require medical attention and thus are reported.
While this is just anecdotal information taken straight from the mouths of owners, it does help explain why little dogs are often referred to as “ankle biters”. It’s also a generalization and is not intended to base sweeping breed assumptions upon. Every dog has a different temperment and should not be judged solely on his or her breed.
