Socializing your puppy is vital and should start early, ideally after they begin receiving their vaccinations. Introduce your puppy to various environments, people, and other animals gradually to foster adaptability and reduce fearfulness. Aim for positive interactions in controlled settings during this sensitive phase, which lasts until about 16 weeks of age. Consistency and positive reinforcement during these experiences help develop a well-rounded adult dog. Always monitor their comfort level, ensuring that socialization remains a positive experience.
