DogsBite.org was recently introduced to a variety of works by internationally acclaimed animal behaviorist Alexandra Semyonova -- born in the U.S. and educated at John Hopkins University and University College London. Semyonova writes with breathtaking honesty about issues that matter the most: the reality of selecting for aggression and the repeated denial by humane organizations and dog breeders that such selection bears no hereditary significance.
Semyonova's 8-page academic paper explains, in easily understandable terms, the roots and results of selective breeding. Semyonova states in the opening sentence, "Probably everyone understands that all dog breeds we have created are a result of our own manipulation of inherited physical traits." Semyonova continues, "Once the discussion started about perhaps banning breeds that, as a breed, have a high tendency to attack and kill, everything got confused."
Semyonova's paper clears up this confusion by discussing how it is possible for behavior to be inherited in domestic dogs.
The paper begins by delving into the "physical conformation" of the dog, the shape that best suits the task the dog has been bred to perform, as well as the "behavioral conformation" of the dog. Both aspects are the result of generations of selective breeding, which is why a poodle can be taught to herd sheep but will never out-perform a border collie in the task. "We have bred certain things into various breeds genetically and thus irrevocably," Semyonova candidly states.
The next two areas talk about "selecting for abnormalities and/or pathologies" and "selecting for abnormal aggression." Semyonova distinguishes the difference between normal dog aggression (normal coping responses in a particular environment) and abnormal aggression (high arousal and aggressivitiy in a safe environment). Two studies are cited in these areas, Peremans (2002) and Van Den Berg (2006), that investigate the role of brain function and heredity in aggression.
The combination of these studies shows that through selection for "aggressive performance," breeders have in fact been selecting for specific abnormalities in the brain. In essence, instead of excluding abnormally aggressive dogs from their breeding stock, Semyonova points out that, "breeders focused on making lineages in which all the dogs would carry these genes (i.e., dogs which would reliably exhibit the desired impulsive aggressive behavior). They succeeded."
The concluding section discusses "form follows function." For example, it is by no mistake that dogs selected for "killing" (the pit bull, dogo Argentino and others) are characterized by exaggerated jaw muscles and the willingness to attack in the absence of species-specific signs. Additionally, the environments for which these behaviors were selected (the fighting pit and escaping slave) are so extreme that there is no appropriate context for them in normal life.
Through discussion and citations, Semyonova carefully maps out her central argument, which is the assertion by humane groups and dog breeders that aggression is not heritable in domestic dogs. This assertion, she writes, given emerging research "is no longer tenable." Furthermore, it is time to stop letting owners and breeders of these dogs deny that they could have known the dog would execute a serious or deadly attack. It is time, instead, to hold them responsible and liable.
