If you have a young dog, you might experience a baffling phenomenon: one day your puppy is completely confident, and the next day they are suddenly terrified of a trash can, a cardboard box, or a familiar neighbor. Don't panic; your puppy hasn't suddenly broken, and your training hasn't failed. They are likely experiencing a developmental stage known as a "fear period." These temporary behavioral milestones occur as a puppy's brain matures, causing them to view the world with sudden, heightened suspicion.

During a fear period, forcing your dog to "face their fears" by dragging them up to the scary object will backfire, making the fear permanent. Instead, use your positive reinforcement tools to build a positive emotional association from a safe distance. If your pup spooks at a lawn ornament, stop moving, let them look at it from afar, and feed them high-value treats for simply observing it calmly. By keeping the experience low-pressure and letting them investigate at their own pace, you will help them ride out the developmental wave and emerge as a resilient, confident adult.
