Why Developmental Stages Matter
Each stage of a puppy’s development comes with unique opportunities and challenges. The socialization window (3–12 weeks) is especially critical — puppies who are positively exposed to a wide range of experiences during this period grow up to be more confident and less fearful.
Missing these windows doesn’t mean all is lost, but it does mean you may need to work harder later. By understanding where your puppy is on the timeline, you can prioritize the right activities at the right time.
The PupStart app creates a personalized training plan based on your puppy’s exact age and breed, so you never miss a critical milestone.
