Resource guarding is a normal canine behavior that becomes a welfare concern when it triggers anxiety in the dog or creates dangerous situations through mismanaged owner responses.
Dogs who guard resources are often doing so from a place of genuine anxiety about losing something valuable. Punishing this anxiety-driven behavior removes the warning signal (growling) without addressing the underlying fear, leading to biting without warning — dangerous for humans and likely to result in euthanasia of the dog. Positive behavior modification that changes the emotional association with resource approach transforms guarding into greeting behavior. The welfare of both the dog and human household members is served by humane, evidence-based intervention.
