Canine Aggression: Welfare Causes and Management

Canine aggression is frequently a welfare symptom rather than a character flaw, arising from fear, pain, frustration or inadequate socialisation, and requires welfare-centred assessment and management.

Key Facts

Fear is the most common emotional motivation underlying canine aggressive behaviour
Pain-related aggression is underdiagnosed and should be excluded in any dog showing new aggressive behaviour
Punitive training methods increase the risk of aggressive behaviour by increasing fear and frustration
Reward-based behaviour modification has strong evidence for improving aggressive behaviour welfare outcomes

Welfare Considerations

Canine aggression is most often a communication of distress rather than an intrinsic behavioural problem. Dogs that have been poorly socialised, are in chronic pain or are experiencing fear live in chronic negative emotional states that increase aggression risk. Addressing the underlying welfare deficit produces better outcomes than suppressing the behaviour without identifying its cause.

What You Can Do

Seek veterinary assessment to exclude pain as a contributing factor in any dog showing aggression
Work with a certified clinical animal behaviourist using reward-based methods exclusively
Never use punishment, aversive tools or dominance-based approaches for aggressive behaviour
Support legislative approaches to dangerous dog behaviour that address training and welfare rather than breed
