Resource guarding in dogs is a normal but often mismanaged behavior that leads to conflict, punishment, and relinquishment, despite being manageable through appropriate behavioral approaches.
Resource guarding creates a welfare cycle where dogs are punished for expressing a natural behavior, which increases their anxiety about resource loss, which intensifies guarding, which elicits more punishment. Dogs caught in this cycle experience chronic anxiety and may develop aggression that leads to relinquishment or euthanasia. The welfare harm comes both from the anxiety underlying guarding and from the punitive responses it elicits. Behavioral welfare is improved by addressing the anxiety that drives guarding through systematic desensitization — teaching the dog that human approach to their resource predicts something better rather than loss. This transforms an anxiety-driven behavior into a trust-based one without punishment or suppression.
