Dog aggression is a welfare concern for the dog experiencing fear or frustration, not just a safety concern for humans, and effective management requires addressing the emotional state driving aggressive behaviour.
Dog aggression welfare requires reframing the problem from a human safety issue to a dog welfare issue that also has human safety implications. Aggressive dogs experiencing chronic fear or pain have severely compromised welfare - the aggressive response is a symptom of distress, not a character flaw. Punishing aggressive behaviour without addressing the underlying cause typically worsens the emotional state and therefore the aggression, while simultaneously damaging the dog-human trust relationship. Effective management involves identifying triggers, managing the environment to prevent exposures, and systematic behaviour modification addressing underlying emotional responses. Veterinary assessment to rule out pain as a trigger is an essential first step in any aggression case.
