Resource guarding is a normal dog behavior that becomes a welfare and safety problem when extreme. Positive behavior modification reduces guarding without punishment and improves household welfare.
Untreated resource guarding creates welfare problems through anxiety around valued resources and risk of punishment that suppresses warning signals. Dogs that receive punishment for growling may bite without warning having learned that growling is not effective. Positive behavior modification reduces the anxiety driving guarding behavior rather than suppressing its expression. Professional guidance is essential for guarding cases involving biting.
