Learned helplessness occurs when a dog ceases to respond in a situation where it has no option to avoid a negative event. For learned helplessness to occur, the event must be both traumatic and outside the dog's control. Family dogs that are exposed to unpredictable or uncontrolled punishment are at risk of developing disturbances associated with the learned helplessness disorder. Punishment which is poorly coordinated with identifiable avoidance cues or response options, such as when punishment takes place long after the event, meet the criteria of inescapable trauma.
