When To Start
Dog socialisation should begin as early as you can. For puppies the ideal time is between 3 and 14 weeks of age.
A good breeder should have started this process for you before you bring your puppy home. The first 3 months are the critical period for dogs so exposing your puppy to as many people, animals, and environments as possible will give them a great start in life. Always make sure this is done in a positive and controlled way.
