I thought it might be fun to discuss puppy development, as our puppies have transitioned from one stage to the next. They were in the “neonatal stage,” but are now in the “transitional stage.”
0-2 Weeks: Neonatal Stage (Dependence)
Completely reliant on mother for warmth, cleaning, and food (colostrum is vital).
Senses of touch and taste are present; sight and hearing are undeveloped.
2-4 Weeks: Transitional Stage (senses awaken)
Sensory Growth: Eyes open (around 2 weeks) for blurry vision, ears start working, and smell becomes more refined.
Physical Milestones: They gain leg strength, begin to stand, and by week 4, can usually walk, run, and play.
Socialization: They start interacting with siblings, learning bite inhibition from play, and get used to being handled gently.
Teeth: Baby teeth (deciduous teeth) begin to emerge.
Early Weaning: Around 3 weeks, start introducing a gruel of milk replacer mixed with softened puppy food.
They can see and hear now, and they have started to communicate with us and each other. I love this stage, as their personalities really start to develop and they begin exploring and learning. They’ve begun climbing, barking and even play growling.
Their development in this stage is so rapid, they change from day to day. Yesterday this little blue girl and both boys, kept climbing in my lap. So they are already seeking out comfort and attention!
This was the green collar smooth boy, now called Sam
This was the red collar rough boy, now called Dean
Sweet Danika, she was the first puppy born, the rough who with the purple collar
This transitional period is crucial for building foundational social skills and sensory processing, setting the stage for future learning and confidence.

As we always try to follow helpful guidelines created by Puppy Culture, these are their recommendations for 2 - 4 week old puppies:
Puppy Culture for 2-4 week old puppies focuses on stimulating their developing senses (touch, smell, sound) and introducing novel experiences like different textures, sounds (classical music, mild noises), and early handling (Early Neurological Stimulation - ENS/ESI) to build stress tolerance, alongside littermate socialization, litter training, and beginning "manding" (sitting for rewards) as they start to walk and eat gruel/soft food, preparing them for the world and building confidence.
Key Activities (Weeks 2-4):
Early Neurological Stimulation (ENS) & Scent (ESI): Gentle exercises like holding puppies in different orientations (head up, head down, supine) and introducing scents (orange, rosemary, banana) helps wire stronger nervous systems.
Sensory Exposure: Introducing new objects, sounds (classical music, thunder/fireworks recordings), and different surfaces (mats, toys) to build "bomb-proofing" and curiosity, not fear.
Physical Development: Pups start walking, pawing, and mock-fighting; they begin to move away from the mother for short periods.
Early Weaning: Introducing softened gruel or meat, often served on different textured surfaces (dishes, frisbees) to get them used to varied feeding environments.
Manding: Teaching them to sit politely to ask for something, starting with taking treats from hands, building self-control.
Litter Training: Introducing a litter box within the whelping area.
Handler Interactions: Daily individual cuddles and positive touch, introducing new people.
Goals for this Stage:
Build a stronger, more resilient nervous system (via ENS/ESI).
Develop problem-solving skills by encountering new things.
Condition them to novel sights, sounds, and textures.
Foster independence from the mother and littermates.
Teach basic manners (manding).
This period is crucial for neurological development, teaching puppies to explore and process the world in a controlled, positive way.
We are so thankful our puppies are all doing well, and can’t wait to share more of their growth and development with you in the upcoming weeks!
The puppies ventured outside for the first time on Monday, and they were not fans! They liked their new toys, and enjoyed the soft bed. But outside was too big, the grass too prickly and there were way too many new smells! It’s the same with every litter, the puppies are always overwhelmed at first.
They definitely like the new toys, but prefer to play inside in the air conditioning! They also like being downstairs now, so they can see everyone.
Nolan, who is not quite 8 months old and is still very much a puppy, was so happy they were moved into the living room. He got to meet the girls for the first time, and fell in love with them. (he is shedding like crazy right now!). Morgan really seemed to like him too. Rory was a little more hesitant about the big guy.
It was a very big day for them, with lots of new experiences. But they recovered quickly, and seemed very happy.
We have so many more adventures planned for them, but we are taking it slow, this was enough for a few days.
They are becoming such beautiful collies, I love their sweet little faces!

There are three kinds of stimulation that influence how a puppy develops. The first, as previously discussed here, is ENS or early neurological stimulation. The second is called socialization. To be the most effective, the ideal time for puppy socialization is between 4 and 16 weeks old. Too much or too little socialization during this period can negatively impact the puppies development, creating fearful, anxious or shy adults.
I’ve written posts about puppy socialization in the past, and they can be found here:
Of course our new puppies aren’t here yet, but we have already reached out to friends in anticipation of their arrival. We’ve asked friends to plan on visiting our puppies, to help socialize them. And they’ve all said yes, because who doesn’t want to cuddle a collie puppy?
The third kind of stimulation is called enrichment. This stimulation has no time limit, as you can begin as soon as the puppies have opened their eyes and have begun to explore their environment. Enrichment provides puppies with positive experiences. This allows the puppies to explore and investigate the world around them while helping build their confidence. Puppies supplied with many different forms of enrichment typically grow up to be more inquisitive and intelligent adults.
There are many forms of enrichment, and we have enjoyed creating new methods with our past litters. I thought it would be fun to share some of the videos from when Peyton and Addi were puppies, as I don’t think I ever shared them here. They show some of our efforts to provide socialization and enrichment.
In this video the puppy with the white on her nose and head is Peyton.
Hungry little puppies, can you spot Peyton?
Melody, now Lilac, was the only rough puppy in the litter. This was her trying out the tunnel for the first time.
This is when we introduced some puppy play equipment.
The puppies can be seen here learning about new, loud noises as a large truck drives by the yard.
Here the puppies met a new friend! They were definitely unsure, but curious, about the talking dragon!
This was the day we introduced the snuffle mat
And here is the first day we introduced their pool. They quickly became fans of the pool, with the hot Summer weather we were experiencing!
I am researching new ideas to provide both socialization and enrichment for the new puppies. I can’t wait to meet them!
I have listened to my coworkers complain about how their dogs do not get along with other dogs. They complain about how they can't take their dogs anywhere. They question why their dogs behave this way, but in may cases, this behavior is the result of a lack of socialization when the dog was young.
For a puppy to mature into a friendly, confident adult dog, he or she must be exposed to many different people, animals, experiences and places. Your puppy should have a variety of interesting experiences, and every new experience should be treated as a fun, new adventure. Your puppy needs to bond with you, so that they trust you to lead the way in these new situations that are potentially frightening to a young puppy. From the time a puppy is 8 weeks old, until she is 16 weeks old, is the ideal time to introduce your puppy to new people, animals, places and experiences.
This includes giving her a first bath, trimming her nails so she doesn't mind you touching her paws. And invite young children, who are gentle, to interact with your puppy under close supervision. If you are a woman, living alone, introduce your puppy to friendly men, especially those in uniform. Begin leash and collar training, most puppies do not like being led by a leash at first, so make it a game and reward them for following you.
But one of the best things you can do for your puppy is help her to learn how to play with other dogs. Many dog training facilities offer Puppy Kindergarten classes, where puppies can play and interact with each other in a safe environment with supervision by trainers.
There is a checklist of things/people you should introduce to your puppy before he or she is 16 weeks old. Unfamiliar People

The idea is to expose your puppy to as many new things, in a fun and positive way, as possible. This will help to prevent your adult dog from reacting with fear or aggression. After all, you could have a dog who never leaves the house/yard and is afraid of strangers or other animals. Or you could have a dog that can go anywhere with you, and who thinks each new experience is an adventure. Which would you want? Kori is very happy that we took her to puppy socialization classes as a puppy, you can see it when you watch her visit Doggie Daycare with my daughter. It's up to you!
