What is the critical socialization period for puppies?

The critical socialization period for puppies begins around 3 weeks and extends to approximately 16 weeks of age. During this time, a puppy's brain is most receptive to learning about their environment, other dogs, and humans. Positive exposure to various sights, sounds, people, and well-vaccinated dogs during this window significantly impacts their future temperament and behavior. Research suggests that puppies lacking adequate socialization during this period are more prone to fear-based behaviors and aggression.
