Why does your dog make himself dead weight the minute you put a leash on him?

When a dog goes limp or becomes "dead weight" when you put a leash on, it can be a sign of reluctance or anxiety about going for a walk. This behavior might stem from a lack of positive associations with the leash or previous negative experiences. Dogs may also seek to assert their independence or simply prefer to stay where they are. Encouraging positive reinforcement and gradually desensitizing them to the leash can help alleviate this behavior.
