There is NOTHING that a human can do in normal, every day encounters that would make it reasonable for a dog to severely attack with intent to kill. Period. The process of domestication of various species is breeding for docility and tameness toward humans, reduced fearfulness, and basically breeding for low hypothalamic-pituitary-adrenal (HPA) axis function (the body's stress/threat detection and response system). With many dogs that we see in the U.S. nowadays, dogs suffer from extreme fear and anxiety which can lead to aggression toward humans, including owners. It is not unusual to hear of dogs who cannot be anywhere near strangers who are minding their own business while walking down the street without the likelihood of aggressive behavior being displayed. Not a guarding context, for which some dogs were bred. When the opposite of "docility" is achieved and aggression is heightened toward humans, something is very wrong. Even livestock guardian breeds are bred for non-lethal deterrence, and not with the intention of killing the trespassing human or wildlife.
This woman reportedly acquired the dogs who nearly killed her from rescue groups and was actively fostering a sixth dog. Many people make excuses for dogs' extreme aggression but the bottom line is that this is completely abnormal behavior that is unfortunately becoming more normalized in the United States. Nearly killing (and reportedly eating) the owner is not a normal way a dog resolves conflict, but it is becoming more common to see dogs display unmodulated aggression nowadays, likely for many reasons, including heightened fear from impoverished socialization, genetics tending toward fear & anxiety, strongly intact prey drive for the full predatory sequence, neglect, and early life trauma/adversity. However, research is also showing evidence of particular genes associated with aggression, increases in particular gene expressions that reduce the modulation of aggressive behaviors in a few breeds, altered neuroanatomy that heighten fear and reduce aggression modulation, and altered hormone and neurotransmitter levels -- all of which can affect the intensity of aggressive behaviors (more on that in a future post with extensive citations). This is important to note because aggression caused by neurological and physiological issues are NOT training issues. You cannot train away mental or physiological illnesses. There may or may not be appropriate medical treatments to make these dogs consistently safe. That is a truth that is immensely difficult for many people to face.
Someone stepping a dog's tail, reaching to pet them too quickly, or going near their food should never result in them being seriously bitten and certainly not mauled to death. Dogs who are unwell (physically or psychologically) may do that. Ritualized aggression is what healthy dogs do to assert boundaries without real harm coming to either party. Both wild canids (within the pack) and domesticated dogs display ritualized aggression (and submissive signs) to resolve conflict -- hard stares, lips raised, growls, and alternatively, head turns, backing away, appeasement licking, rolling over, etc.
Additionally, rescues need to stop adopting out dogs like this. It is business-as-usual for me to see dogs adopted out from local rescues that immediately begin displayed some pretty serious aggression in their new homes. Adopters and fosters, in my experience, often are told little/nothing about the dogs' histories except sometimes being told that they were "saved" from shelter aggression euthanasia lists. There is a lot of faith put into these organizations that they know the dogs' histories and have vetted the dogs as "safe" to be in their home, but that is not always the case. There is no mandatory period or record keeping for rescues, at least in Nevada, for testing and documenting the behavior of a dog before he/she is adopted out into the community.
There are lots of wonderful dogs out there who need homes, but the adoption of seriously aggressive dogs of any breed only deters people from ever wanting to trust a rescue organization enough to adopt a rescue. I am hopeful that the rescues in this case are held legally responsible for the injuries to this woman if there was any shred of evidence that these dogs displayed aggression before adoption or if there was a lack of adequate vetting of the dogs prior to adoption. Adopting dangerous dogs -- human aggressive or severely dog-aggressive -- out into the community puts everyone at risk. People accidentally forget to latch doors, people may drop a leash during a walk, the backyard gate can blow open, owners can have medical events while walking their dogs that result in them losing control. It should not result in serious injury (or death) to someone if a dog gets loose. Yet, we see people killed by dogs regularly who were loose roaming the neighborhood, or going after their own family members in their own homes.
Bottom line.
Please don't believe this type of high intensity severe aggression is normal. It is very ABNORMAL behavior and the opposite of what domestication is supposed to achieve. When seeing a loose dog on the streets, no one should have to be afraid to approach that dog to leash them and take them to safety for fear of serious bodily harm and/or losing their life. A small nip or bite on the hand that barely breaks skin is different than an uninhibited multi-bite attack intended to kill the victim. This has nothing to do with breed but everything to do with vetting for normal versus abnormal behavior in the dogs we allow into our homes and communities. It is not helping dogs to place them in situations where they are set to fail.
As a reminder -- trolls will have their comments deleted.
