Aggression in dogs is frequently rooted in fear and anxiety rather than dominance. Understanding this changes how welfare-conscious owners and trainers should respond.
Aggressive behaviour in dogs is almost always a sign of welfare compromise — chronic fear, pain, social conflict, or prior experience of failed communication. A dog that bites has typically communicated its distress through dozens of earlier signals — yawning, lip licking, stiffening, growling — that were either missed or actively suppressed by owners using punishment. Suppressing these signals does not remove the underlying fear; it removes the warning system, making bites more likely without prior warning. Welfare-centred approaches to aggression involve identifying and addressing the underlying fear or pain, not punishing the symptom. This protects both the dog and the humans around it.
