Stress is the most usual cause of escape behavior. An escape that succeeds is likely to be repeated. Before Zum’s bucking and running away habit can be broken, its component parts must be unlearned. I have my work cut out for me. I have to retrain Zum completely. His fear of doing a task is equal to his fear of not doing it. I have to relieve his stress every step of each activity that I do with him. Then I need to substitute reward and build security.
