ENS and Early Socialization: How We Raise Confident Goldendoodle Puppies

One of the most common questions we get from families on our waitlist is some version of this: “What are you doing with the puppies before we pick them up?” It’s a great question, and the answer matters more than most people realize.

At Strong Oaks, every puppy goes through a structured early development program from day one. Here’s what that looks like and why it makes a difference in the dog your puppy grows up to be.

What Is ENS?

ENS stands for Early Neurological Stimulation. It’s a set of five specific handling exercises performed once daily during days three through sixteen of a puppy’s life — a narrow developmental window when the neurological system is rapidly maturing and uniquely responsive to mild stress.

The five exercises are simple: briefly holding the puppy in different positions, stimulating between the toes with a cotton swab, and exposing them to a cool surface. Each exercise takes only three to five seconds. Together they take less than a minute per puppy per day.

The research behind ENS comes originally from the U.S. military’s Biosensor program, which studied ways to improve the performance of working dogs. What they found was that puppies who received ENS during that critical window showed measurable differences compared to those who didn’t — stronger cardiovascular systems, stronger adrenal glands, more resistance to disease, and greater tolerance for stress.

In practical terms: ENS puppies tend to be calmer under pressure, more adaptable to new situations, and easier to train. For a family dog that’s going to encounter kids, strangers, loud noises, car rides, and vet visits for the next decade, that foundation matters.

Beyond ENS: The Super Puppy Protocol

ENS is just the beginning. Starting around day three and continuing through the first several weeks, we also introduce what’s sometimes called the Super Puppy or Puppy Culture protocol — a broader early socialization framework that includes:

Gentle handling by multiple people from the earliest days. Our puppies are touched, held, and talked to by our family constantly. They hear normal household sounds — the TV, the dishwasher, kids playing, doors opening and closing — from birth. None of these things should be a surprise to a puppy by the time they go home.

Introduction to novel surfaces, textures, and objects. Puppies explore different floor surfaces, gentle sounds, and new smells in a controlled, positive way. The goal is a puppy that approaches new things with curiosity rather than fear.

Early litter socialization. Puppies learn from each other. Play between littermates teaches bite inhibition, reading body language, and basic social skills that carry over to how they interact with other dogs for the rest of their lives.

The Critical Socialization Window

Between three and twelve weeks of age, puppies have what behaviorists call the socialization window — a period when new experiences are absorbed and normalized far more readily than at any other point in their development. What a puppy experiences (or doesn’t experience) during this window shapes their temperament in ways that are very difficult to reverse later.

This is why where and how a puppy spends those first eight weeks matters so much. A puppy raised in a quiet kennel with minimal handling will have a fundamentally different nervous system than one raised inside a family home with daily stimulation and human interaction.

At Strong Oaks, our puppies are born and raised in our home. Not in a kennel, not in an outbuilding — in the house, with the sounds and rhythms of daily family life surrounding them from day one.

What This Means for Your Family

When you bring home a Strong Oaks puppy, you’re getting a dog that has already had eight weeks of intentional preparation for life with a family. They’ve been handled daily, exposed to normal household sounds, introduced to different surfaces and experiences, and socialized with people of different ages.

That doesn’t mean they won’t need continued socialization from you — they absolutely will. The socialization window extends to twelve weeks, so the first few weeks after pickup are critical. Take your puppy to new places, introduce them to new people, let them experience the world in a positive, controlled way. What we start, you continue.

But you’re starting from a much stronger foundation than you would be with a puppy that spent its first eight weeks in a cage.

A Note on ENS and Your Vet

Some veterinarians aren’t familiar with ENS or the Super Puppy protocol. If your vet asks what we do with our puppies before they go home, feel free to share this post or direct them to the research. We’re happy to answer questions from veterinary professionals too — just give us a call.
