pup’s socialization is based on their mother’s attitude
A basic part of a pup’s socialization is based on their mother’s attitude–relaxed or skittish–toward people. The way you interact with your new puppy can play a big role, too. Playing, petting, and talking with your pup can help him or her develop the “people skills” needed to be a good member of the family and the neighborhood.
While weaning for puppies can take place at six to seven weeks, they are still learning important skills from their littermates as their mother gradually leaves them for longer periods of time. Puppies that stay with their litter for at least three months are more likely to develop good social skills as they act as role models for each other.
