Socialization – What’s The Big Deal?

Socialization is much more than introducing puppies to other dogs. It’s more than

trips to the dog park and puppy parties in your living room. Getting a puppy out in

the world to observe and take in common and random sights, sounds and

environments is socializing it. Exposing your puppy to life beyond your home is an

important part of development. Their critical socialization period ends at 16 weeks.

Once that window closes, it does not open again. Ever.

Socialization is the single most critical period for a dog’s emotional well-being. Whereas

vaccinations are critical for your pup’s physical health, exposure to the world in a safe

manner is paramount for a pup’s mental health. What they are exposed to at a young

age imprints that those noises, sights and experiences are not to be feared. It’s like

anti-anxiety vaccinations for your puppy. If your puppy is kept under lock and key

indoors until 4 months old, when vaccinations are typically complete, there is a good

chance your puppy will be fearful and potentially aggressive as it grows up.

Be very mindful of your pup’s vaccination schedule and do not risk going to public

parks or dog parks. Instead, drive your pup and hold them as you step out of the car

for a few minutes. It doesn’t take much to expose your dog to the various sights and

sounds the world is filled with. A strip mall or grocery store parking lot will expose

your little one to many, many different people (walking gaits, height, weight, color,

clothing – hats, heavy boots, baggy jackets), as well as vehicles (motorcycles, trucks,

big trucks and maybe even bicycles and skateboards). Being able to observe these

stimulations from the safety of your car or in your arms will do your pup a big favor.

If anyone wants to pet them, go for it!

If your home does not have children, try taking the puppy to a schoolyard or

playground where they can watch and hear the screams and giggles coming from the

area. Basketball, baseball or other games on the playground are a bonus. Even

having visitors to your home will ensure your puppy that other people are friendly.

There is no need to run away from them, or worse bark as if they are a threat.

Oh! Let’s not forget construction sites with hammering, drilling and various unusual


This is an open letter from Dr. R.K. Anderson, who encourages veterinarians and puppy guardians to make puppy socialization a first priority. Socialization cannot be overrated.

Puppy Vaccination and Socialization Should Go Together

TO: My Colleagues in Veterinary Medicine:

Common questions I receive from puppy owners, dog trainers and veterinarians concern: 1) what is the most favorable age or period of time when puppies learn best? 2) what are the health implications of my advice that veterinarians and trainers should offer socialization programs for puppies starting at 8 to 9 weeks of age.

Puppies begin learning at birth and their brains appear to be particularly responsive to learning and retaining experiences that are encountered during the first 13 to 16 weeks after birth [Dr. Anderson is saying that the prime time for puppy socialization stops somewhere between 13 and 16 weeks, although more socialization occurs after that time]. This means that breeders, new puppy owners, veterinarians, trainers and behaviorists have a responsibility to assist in providing these learning/socialization experiences with other puppies/dogs, with children/adults and with various environmental situations during this optimal period from birth to 16 weeks.

Many veterinarians are making this early socialization and learning program part of a total wellness plan for breeders and new owners of puppies during the first 16 weeks of a puppy’s life — the first 7-8 weeks with the breeder and the next 8 weeks with the new owners. This socialization program should enroll puppies from 8 to 12 weeks of age as a key part of any preventive medicine program to improve the bond between pets and their people and keep dogs as valued members of the family for 12 to 18 years.

To take full advantage of this early special learning period, many veterinarians recommend that new owners take their puppies to puppy socialization classes, beginning at 8 to 9 weeks of age. At this age they should have (and can be required to have) received a minimum of their first series of vaccines for protection against infectious diseases. This provides the basis for increasing immunity by further repeated exposure to these antigens either through natural exposure in small doses or artificial exposure with vaccines during the next 8 to 12 weeks. In addition the owner and people offering puppy socialization should take precautions to have the environment and the participating puppies as free of natural exposure as possible by good hygiene and caring by careful instructors and owners.

Experience and epidemiologic data support the relative safety and lack of transmission of disease in these puppy socialization classes over the past 10 years in many parts of the United States. In fact; the risk of a dog dying because of infection with distemper or parvo disease is far less than the much higher risk of a dog dying (euthanasia) because of a behavior problem. Many veterinarians are now offering new puppy owners puppy socialization classes in their hospitals or nearby training facilities in conjunction with trainers and behaviorists because they want socialization and training to be very important parts of a wellness plan for every puppy. We need to recognize that this special sensitive period for learning is the best opportunity we have to influence behavior for dogs and the most important and longest lasting part of a total wellness plan.

Are there risks? Yes. But 10 years of good experience and data, with few exceptions, offers veterinarians the opportunity to generally recommend early socialization and training classes, beginning when puppies are 8 to 9 weeks of age. However, we always follow a veterinarian’s professional judgment, in individual cases or situations, where special circumstances warrant further immunization for a special puppy before starting such classes. During any period of delay for puppy classes, owners should begin a program of socialization with children and adults, outside their family, to take advantage of this special period in a puppy’s life.

If there are further questions, veterinarians may call me at 651-644-7400 for discussion and clarification.
