Is 4 months too late to socialize a puppy?

Puppies go through a critical socialization period from 6 to 16 weeks of age that will dramatically impact their behavior for the rest of their lives. During this period, their brains are like tiny sponges – soaking up everything they experience and filing it away for the future. Whatever puppies see at this age, they will consider a normal part of life as adults. Beyond 16 weeks, something happens, new things, which before were accepted with cheerful curiosity and a wagging tail, are now met with suspicion. You may have met adult dogs who are fearful of everyday objects or unfamiliar people; in many cases, this is the end result of poor socialization during this all-important period. Your puppy will not be fully vaccinated until after she’s 4-5 months old, if you wait until then, you’ve already missed your opportunity. The American Veterinary Society of Animal Behavior feels so strongly about this issue that they published a position statement on puppy socialization in 2008, stressing that owners should be introducing their puppies to new places, people and other dogs prior to completing their vaccination series. Just do it before 16 weeks of age.

It’s not too late but it’s important for you to be careful with your socialization strategy. If we’re talking about dogs over 6-7 months you’ve missed the critical time period when puppies are most impressionable because, even though they’re still young, your pup is starting to move into adolescence. This is when anxiety starts to present when they start to form preferences, and when it’s okay for them to have those preferences! By 7-8 months you’ve started to lose that flexibility that comes with a younger pup’s impressionability and it’s important for you to not force interactions. Ideally socializing your puppy when they’re still within the impressionable stage is best but you’re not necessarily too late either! It’s about shifting from quantity of socialization to quality. Socializing doesn’t necessarily mean interaction: Don’t force interactions after a dog is 7-8 months if they’re still hesitant to be social. Know when it’s better to limit social time: Just like humans, dogs get less social as they get older. If your pup doesn’t have the social need and they’re not successfully socializing with other dogs it can be helpful to think about why you want your pup to socialize.
