How Dogs Become Aggressive
The two most common causes of aggression in dogs are poor pack structure, which can lead to dominance aggression.
And second, aggression based in the fight/flight response of the defensive drive, which leads to fear aggression.
17 Types of Aggression in Dogs

drive)
Dominance Aggression
Dogs are pack-oriented animals that see themselves in relationship to others—a hierarchy.
A dog has no other way of relating to his family pack. The requirement for rank and order are a matter of survival and anchored in the pack drive.
A dog who views itself as higher-ranking than some or all family members can act aggressively to assert its position when things don’t go its way. This is referred to as poor pack structure.
A dog should never be allowed to rank above a human.
Dominance Aggression cont.Dominance can form in several ways:
• Genetic predisposition for dominance at birth.
• Adding or removing dogs to or from a home, require the adult family pack to re-establish the hierarchy.
• A dog that only respects one family member can create a false sense of safely in their presence.
• Moving with dogs requires them to re-establish the pack hierarchy at the new location.
Dominance Aggression cont.Dominance aggression is mostly caused by poor pack structure.
Resolution Approach:• Strong leadership and proper pack-structure• Correction-centered counter-conditioning approach
Fear AggressionFear-based aggression is the most common form of aggression. It is based in the fight or flight response of the defensive drive.Characteristics:• Weak nerves• Can’t handle stress• Dog learned that aggression is the best defense• Aggression escalates if successful• Dog is emboldened each time
Resolution Approach:• Strong leadership and proper pack-structure to make the dog feel safe• Balanced counter-conditioning approach
Possessive AggressionSimilar to dominance aggression but more focused on objects or locations. I.e. food bowls, toys, furniture, beds, or crates.
Resolution Approach:• Strong leadership and proper pack-structure• Correction-centered counter-conditioning approach (negative punishment)
Characteristics:• Object guarding• Dog growls and shows teeth when approached while guarding• Dog bites when trying to claim objects from it.
Territorial AggressionUsually observed with dominant dogs or dogs with fear-based aggression.
Resolution Approach:• Strong leadership and proper pack-structure• Counter-conditioning approach depends on root cause
Characteristics:• Strong pack drive• Unfamiliar people or animals are not welcome in the pack.• Responds to intrusion with aggression• Dogs consider every area they regularly pass through their territory—not just
the home or yard
Predatory AggressionCommonly directed towards smaller animals or small children and babies in motion.
Characteristics:• High prey drive• Genetic predisposition to chase and bite things that move quickly
Resolution Approach:• Strong leadership and proper pack-structure• Balanced counter-conditioning approach
Play AggressionPart of dominance aggression. Play can escalate, become too rough and turn into aggression.
Characteristics:• Never play tug games with a play aggressive dog unless you can control it
Resolution Approach:• Strong leadership and proper pack-structure
Inter-Male AggressionPart of dominance aggression and directed towards other male dogs.
Characteristics:• Such dogs are often comfortable with female dogs. • Neutering can help but only leads to noticeable improvements about 40% of
the time.
Resolution Approach:• Neutering between 6 and 8 months—before the dog reaches sexual maturity.• Strong leadership and proper pack-structure• Correction-centered counter-conditioning approach
Inter-Female AggressionPart of dominance aggression and directed towards other female dogs. Considered the worst kind of dog aggression.
Characteristics:• Significantly higher levels of brutality and determination than with inter-male
aggression.• Such dogs are usually comfortable with male dogs.• Often triggered by hormones when one of the females enters the heat cycle.• Spaying can make the aggression issues more severe.
Resolution Approach:• Spaying between 6 and 8 months—before the dog reaches sexual maturity.• Strong leadership and proper pack-structure• Correction-centered counter-conditioning approach
Animal AggressionSuch dogs get along with other members of their own species—male and female—but attack other animals.
Characteristics:• Attack non-canine animals like chickens, cats, horses, cattle and so forth.
Resolution Approach:• Strong leadership and proper pack-structure• Correction-centered counter-conditioning approach
Pain-elicited AggressionDogs in pain can show aggression upon touch by the owner or a veterinarian.
Characteristics:• Preventable by building strong trust and respect.• Can also occur through improper use of remote collars by inexperienced
handlers.
Resolution Approach:• Strong leadership and proper pack-structure
Punishment-elicited AggressionDogs with serious dominance problems can bite their handler when receiving strong corrections during training.
Characteristics:• Tends to occur only with hard temperament dogs—i.e. police dog candidates
Resolution Approach:• Strong leadership and proper pack-structure• Correction-centered counter-conditioning approach
Redirected AggressionOccurs when a dog is highly excited by an external stimulus and the handler or another dog gets to close.
Characteristics:• High-energy and excitement• The bite is a reflex
Resolution Approach:• Strong leadership and proper pack-structure• Correction-centered counter-conditioning approach
Maternal AggressionMaternal aggression is observed in female dogs protecting their puppies.
Characteristics:• Some female dogs become highly aggressive after a litter is born and attack
anyone coming near the puppies• Tends to resolves itself within one week and disappears completely once the
puppies are weaned from the mother.
Resolution Approach:• n/a – just be patient• Somewhat preventable by a good pack structure, trust and respect
Medical AggressionSome aggression has medical issues. I.e. thyroid malfunction, brain tumors and some auto immune disease medication.Characteristics:• Sudden onset of unexplainable aggression without any changes in the dogs
lifestyle.• NO build-up of aggressive behaviors over time.
Resolution Approach:• Medical treatment
Displaced AggressionCan occur in under-exercised or under-stimulated dogs
Characteristics:• Random attacks on other dogs, people or objects.• Can be triggered by loud noises or surprises
Resolution Approach:• Provide sufficient exercise and mental stimulation• Strong leadership and proper pack-structure
Genetic AggressionSome people believe certain breeds are genetically programmed to be aggressive. There is NO evidence for this belief.
Characteristics:• However, within a breed, certain families of dogs can genetically be predisposed
to be dominant or aggressive.
Resolution Approach:• Problems preventable with strong leadership and proper pack-structure
Defensive Aggression (aka fight drive)
• View a human opponent as a challenge to be defeated.• Don’t fear humans in any way and attack when
challenged.• Losing against a human is not something such dogs think
is possible.• Not territorially restricted. Will fight a human anywhere.• Only present in mature dogs with the right temperament
and training.• This is a trained behavior and doesn’t occur with family
pets.
These are characteristics of a good police service dog.
How To Resolve Aggression in Dogs• Establish proper pack structure—people first. This is
accomplished by controlling a dogs environment and life to 100% with crates and leashes for a period of time (usually 3-4 months).
• Teach dog leadership skills. Dog owners must become pack leaders.
• Counter-condition adopted behaviors to break the automatic fight response.
