What is the Puppy Socialization Window?

The puppy socialization window is the critical developmental period from 3-12 weeks of age during which puppies are neurologically primed to accept new experiences without fear. During this window, the brain is extraordinarily flexible - positive exposure to diverse people, animals, environments, sounds, and handling shapes adult temperament more profoundly than any other factor. A secondary socialization window extends from 12-16 weeks, though puppies become progressively more cautious as the window closes.
