Resource guarding in dogs is a normal canine behavior that becomes a welfare and safety concern when it is severe, leading to inappropriate punishment responses.
Resource guarding creates welfare concerns for both the dog and their human family. Dogs who guard resources intensely experience chronic anxiety around valued objects and people. Owners who punish growling risk suppressing warning signals, creating dogs that bite without warning. The welfare-optimal approach treats resource guarding as a trainable behavior problem through systematic desensitization: approaching at a distance that does not trigger guarding while offering high-value treats, gradually reducing distance until the dog associates human approach with positive outcomes. Severe resource guarding that poses safety risks requires veterinary behaviorist assessment. The welfare of the dog includes protection from punishment-based methods that cause fear and pain without addressing the underlying anxiety.
