Dog-Dog Aggression Rehabilitation Protocols

Dog-dog aggression is one of the most common behavioral referrals, with systematic behavior modification significantly improving outcomes for most cases.

Key Facts

Dog-dog aggression affects an estimated 15-20% of dogs and is among the top reasons for surrender to shelters
Two types are commonly distinguished: frustration-based (leash reactivity) and conflict aggression between familiar dogs
Fear is the underlying driver in the majority of inter-dog aggression cases - aggression is a distance-increasing behavior
Punishment-based methods suppress visible behavior while increasing underlying fear and often worsening aggression over time
Systematic desensitization and counter-conditioning protocols produce lasting improvement in 60-70% of cases with consistent work

Welfare Considerations

Dogs exhibiting inter-dog aggression typically suffer from fear and anxiety that the behavior is attempting to manage. Interpreting aggression as dominance rather than fear leads to punishment-based responses that compound the welfare harm. Dogs who injure other dogs are often euthanized unnecessarily when systematic behavior modification with a qualified behaviorist could resolve the underlying fear. Access to qualified, force-free behavioral support is a welfare issue - availability and cost barriers mean many dogs do not receive help that could save their lives.
