Dog Reactivity and Fear-Based Behaviour: Understanding and Helping Reactive Dogs

Reactive dogs that bark, lunge, or growl at triggers suffer from fear or frustration. Evidence-based approaches help reactive dogs and prevent escalation to aggression.

Key Facts

Welfare Considerations

Reactive dogs experience significant emotional suffering — their reactivity is a behavioural expression of fear, frustration, or conflict about an approach-avoidance situation. Owners who punish reactive behaviour with corrections or punishment suppress the warning signals (growling, barking) while leaving the underlying emotional state unchanged, increasing bite risk. Effective treatment aims to change the emotional response to triggers: through systematic desensitisation (gradual, controlled exposure at sub-threshold distances) and counter-conditioning (creating positive associations with previously feared triggers), dogs can learn that triggers predict good things rather than threat. Management that avoids triggering situations while treatment progresses prevents rehearsal of the reactive response. Many reactive dogs can achieve significant improvement with appropriate treatment and owner commitment.
