INTENTIONAL EARLY DEVELOPMENT
Our Next Level Puppy Program
Every Harman Corgi puppy is intentionally raised through a carefully designed early development program that helps build confidence, resilience, and a smoother transition into family life. Rather than following a rigid checklist, we introduce each new experience when puppies are developmentally ready, helping them build confidence through positive, age-appropriate learning that is tailored for each individual puppy.
Why Early Experiences Matter
The first few months of a puppy’s life are a remarkable period of growth. During this time, their brains, senses, and bodies develop rapidly, making early experiences especially important in shaping how they respond to the world around them.
Our Next Level Puppy Program is built on the proven principles of Puppy Culture, along with additional science-backed research in canine behavior and development.Every activity has a purpose, but we don’t simply follow a checklist or calendar. We follow the puppies.
Every litter develops a little differently, so new experiences are introduced when puppies are physically and mentally ready for them. For example, introducing household sounds wouldn’t accomplish much before a puppy’s ears have opened. By matching experiences to development, we can help puppies build confidence through positive, age-appropriate learning.
Birth to Go-Home Timeline
Puppies don’t just grow each week physically—they also go through important stages of brain development. As their brains mature, they become ready for new experiences and new skills to build the confidence that helps prepare them for life with their future families.
Our program evolves alongside them, introducing experiences that match each stage of development.
Birth - Day 14
During the first two weeks, puppies spend nearly all of their time nursing and sleeping while their bodies and nervous systems develop. Their eyes and ears remain closed, so their world is experienced primarily through touch and scent.
Beginning around day three, puppies who are healthy and thriving begin Early Neurological Stimulation (ENS) and Early Scent Introduction (ESI). These brief, carefully controlled exercises introduce tiny amounts of stress at a time when the nervous system is rapidly developing. Research suggests these early experiences may support improved resilience, cardiovascular performance, and stress recovery later in life.
Just as importantly, each puppy receives daily gentle handling and close observation to ensure they are healthy, comfortable, and growing appropriately.
Days 15-21: The World Begins to Open
Week three marks an exciting milestone in a puppy’s development. Between days 14 and 18, their eyes begin to open, followed a few days later by their ears unsealing. For the first time, puppies can begin to see and hear the world around them. As their developing brains begin processing these new sights and sounds, we can start introducing gentle sensory experiences.
As each puppy reaches these developmental milestones, we gradually expand their environment with small, positive experiences designed to build confidence and adaptability as their world grows.
As puppies become stronger, they begin taking their first wobbly steps and can eliminate on their own. This natural milestone allows us to begin laying the foundation for potty training by creating separate sleeping and potty areas within the whelping area.
During Week Three, Puppies Begin Experiencing:
- Daily gentle handling and positive human interaction
- Introduction to soft, low-volume household sounds and music
- Gradual increases in light levels
- A comfortable bed with new textures
- A designated potty area to begin early potty training habits
- Close observations to ensure each puppy is progressing at their own pace
Days 22-28: Curiosity Takes Over
During Week Four, Puppies Begin Experiencing:
Week four marks the beginning of the critical socialization period—one of the most important stages in a puppy’s development. From approximately 4 to 16 weeks of age, puppies’ brains are developing in ways that make this period unlike any other in their lives. They are especially receptive to new experiences. Like little sponges, they absorb information about the world around them and begin building a foundation they will draw upon throughout their lives.
We take advantage of this important developmental window by intentionally introducing a variety of positive, age-appropriate experiences while puppies are naturally curious and eager to explore.
As tiny teeth begin to emerge, puppies naturally investigate more of their world with their mouths, and we introduce puppy mush as they begin transitioning from nursing. Their environment also expands and changes regularly with carefully selected toys, textures, objects, sounds, and simple challenges that encourage curiosity, exploration, and problem-solving.
Because puppies typically show relatively little fear at this age, we also begin gentle startle and recovery exercises. The goal isn’t to prevent puppies from ever being startled—it’s to help them learn to recover from mild, unexpected experiences and continue exploring. These early experiences can help build confidence and adaptability as their world becomes larger.
- Introduction to puppy mush as baby teeth erupt
- An enriched environment filled with new objects and textures
- Interactive toys that encourage exploration and problem-solving
- Sound desensitization using a variety of everyday household noises
- Gentle startle and recovery exercises to build resilience
- First exposure to water and learning to lap liquids
- Continued litter box training to strengthen early potty habits
- Daily handling and positive human interaction
Days 29-35: Building Emotional Resilience
As puppies continue to develop, they become more aware of the world around them and begin recognizing that not everything is the same. Some puppies may experience a brief fear period—a normal stage of development when they begin distinguishing between what feels familiar and what may be unfamiliar.
Because every puppy develops at their own pace, we carefully observe each individual and adjust experiences as needed. Our goal is never to overwhelm or frighten a puppy. Instead, we provide positive, age-appropriate experiences that help puppies learn to recover from new or unexpected situations and build emotional resilience.
During this stage, we intentionally expand each puppy’s “mental library” by introducing new experiences every day. Each positive interaction with a different surface, object, sound, person, or animal becomes another reference point they can draw upon when they encounter something unfamiliar later in life.
Social development also expands as puppies begin interacting with a wider variety of friendly people, well-mannered adult dogs, and our barn cats through safe, supervised experiences. They meet people wearing hats, coats, masks, and other unfamiliar clothing, helping them learn that people can look different and still be safe.
Preparing for family life continues as puppies begin eating meals individually in crates, building positive associations with the crate while encouraging calm mealtimes and good manners. Regular grooming also continues with nail trims, gentle brushing, and positive handling so routine care becomes a familiar part of life.
During Week Five, Puppies Begin Experiencing:
- Daily introduction to new sights, sounds, textures, and novel objects
- Interactive toys that encourage exploration and problem-solving
- Household appliance and everyday home sound confidence training
- Individual crate feeding to build positive crate associations & manners
- Continued potty training foundations
- Weekly nail trims, brushing, and gentle grooming exercises
- Daily handling and confidence-building activities for each puppy
- Safe, socialized interactions with people, adult dogs, and barn cats.
Days 36-42: Building Relationships and Life Skills
By Week Six, puppies are becoming more social, interactive, and affectionate. They actively seek out people for attention and play, making this an ideal time to strengthen the human-dog bond while continuing to build confidence through positive experiences.
As their curiosity and confidence grow, we continue expanding each puppy’s mental library by introducing new sights, sounds, textures, and experiences every day. Everyday household activities become part of normal life as puppies continue developing confidence around common sounds and routines they are likely to encounter in their future homes.
This is also an important stage for introducing the foundations of good manners. Through gentle redirection and positive reinforcement, puppies begin learning appropriate ways to interact with people, including replacing playful biting with appropriate toys and learning that calm behavior earns attention and rewards.
Preparing for family life continues with introductions to harnesses, regular baths, different walking surfaces, and additional handling exercises. By pairing new experiences with positive outcomes, we help puppies develop positive associations with the people, routines, and experiences that will become part of everyday life.
During Week Six, Continue Begin Experiencing:
- Daily positive interaction and affection with people
- Confidence building around household sounds and routines
- New novel objects, textures, and enrichment activities
- Expanded social experiences with people and friendly animals
- Foundations of polite manners, including gentle bite inhibition
- Fun recall games and early responsiveness to people
- Introduction to harnesses
- Weekly baths and continued grooming exercises
- Continued potty training and crate confidence
- Positive associations with new experiences
Days 43-49: Confidence in Action
By Week Seven, puppies are becoming confident, curious, and increasingly engaged with the world around them. Their growing independence and openness to new experiences make this an ideal time to introduce more real-world experiences while continuing to build positive associations with new people, places, and activities.
This is when we begin bringing together many of the skills puppies have been developing over the previous weeks. Rather than simply introducing new experiences, we’re helping puppies learn how to think, solve problems, and respond appropriately in everyday situations. Every successful interaction adds another chapter to their growing mental library, preparing them to adapt confidently as they encounter new experiences throughout life.
Puppies begin learning simple manners, including sitting calmly before meals and for attention, while early marker training helps them understand how learning works. These short, enjoyable sessions encourage puppies to think, make choices, and build confidence through success.
As their world continues to expand, puppies experience car rides, stroller rides, outdoor adventures, moving objects, different surfaces, and a variety of everyday sounds. By building on previous positive experiences, we help puppies develop the confidence to approach increasingly complex situations with curiosity.
During Week Seven, Puppies Continue Experiencing:
- Sitting calmly before meals and for attention
- Early marker training through fun, positive learning games
- Recall games that strengthen responsiveness to people
- Introduction to barriers and simple problem-solving challenges
- Car rides and stroller rides
- Outdoor exploration in safe environments
- Confidence around moving objects and everyday activity
- Continued exposure to new sounds, textures, and novel experiences
- Positive interactions with people and animals in their social group
- Weekly grooming, handling, and bath routines
As puppies’ personalities become more consistent, we begin evaluating the individual traits, confidence, energy level, and social preferences of each puppy in preparation for temperament testing and family matching. These evaluations, combined with the observations we’ve gathered over the previous weeks, help families better understand who each puppy is before puppy selection.
Week 8-9: Ready for Family life
By the final weeks before go-home day, puppies are energetic, playful, and full of personality. They find their voices, race through joyful “zoomies,” wrestle with their littermates, and eagerly investigate everything around them. While they may look like carefree puppies, these final weeks are an important opportunity to reinforce the confidence, curiosity, and life skills they’ve been building since birth.
By now, each puppy has built a growing mental library filled with weeks of positive experiences. During these final weeks, we continue reinforcing those experiences while giving puppies opportunities to use the confidence and skills they’ve developed in increasingly real-world situations.
This stage focuses on preparing puppies for the routines of everyday family life. Through short, enjoyable training sessions, puppies continue practicing polite manners, strengthening recall, and learning that calm behavior earns rewards. Nose work games encourage problem-solving and confidence while giving puppies an opportunity to use their natural sense of smell.
Real-world experiences continue as puppies enjoy car rides, stroller rides, outdoor adventures, new textures, moving objects, household sounds, and daily opportunities to investigate novel items. Positive chew sessions help redirect normal puppy biting toward appropriate toys while supporting healthy teething habits.
As go-home day approaches, our goal is to send each puppy home with a strong foundation of confidence, curiosity, resilience, and positive experiences that their family can continue building upon.
During Weeks Eight & Nine, Puppies Continue Experiencing:
- Daily novel objects and new experiences
- Nose work and scent games
- Recall games and responsiveness to people
- Calm manners before meals and attention
- Positive chew sessions during teething
- Car rides and stroller rides
- Outdoor adventures and environmental exploration
- Continued confidence around household sounds and movement
- Barrier exercises and simple problem-solving games
- Grooming, handling, baths, and nail care
- Continued potty training and crate confidence
The Learning Continues at Home
Your puppy’s early development doesn’t end on go-home day. The important socialization period continues until approximately 16 weeks of age, making the first several weeks at home an important continuation of the work we’ve already begun.
We provide our families with resources to help them continue introducing positive experiences, establish routines, work on crate and potty training, and help their puppy adjust to life in their new home.
The goal isn’t to finish your puppy’s education before they leave us—it’s to give you and your puppy a strong foundation to continue building together.
