Since
the primary socialization period for dogs ends by 3 months of age, puppy socialization classes are most valuable for puppies 8 weeks of age and older.
The best time to teach them is during
the primary socialization period, which is roughly from 2 to 7 weeks of age.
Behaviorists recommend they meet at least 100 people during
the primary socialization period.
This is when
the primary socialization period ends; socialization is still possible after this time but will take longer and may not be as successful.
The primary socialization period for dogs begins at 3 weeks of age and is diminishing by 12 weeks.
Exposure to animals of other species when dogs are young can help as well, but it's not foolproof, and
the primary socialization period for dogs is short, ending at between 12 and 14 weeks of age.
In
the primary socialization period they learn how to be a dog, in the human socialization period they learn how to navigate our complex world and everything in it.
Keeping in mind that
the primary socialization period ends at 12 weeks of age — go to puppy socials early and often!
