Although Pomeranian growth stages week by week are quite predictable, every puppy and dog breed is unique and differs a little at each stage of their puppy development.
Similar to how humans develop, Pomeranian pups also have a predictable pattern of steps, although there has never been any official agreement regarding the exact ages a puppy maybe when each step is taken.
Small toy breeds like Pomeranians develop quickly, many reaching maturity before bigger dog breeds.
The previous rule stating that one dog year is the same as seven years for a person is untrue. Smaller dogs mature earlier than big dogs, and the Pom females are often only 6-7 months of age when experiencing their first heat.
Puppy Development Stages Month by Month
At What Age Do Pomeranians Stop Growing?
A 1-year-old Pomeranian is a fully grown adult dog. Numerous changes occur in a puppy’s first year of living. He starts as a relatively helpless newborn pup, unable to hear, see or go potty alone.

An Overview of Pomeranian Life Stages
Newborn Pomeranian Puppy Stage
When the puppy is firstborn, his ears and eyes are shut. Only his senses of taste, touch, and smell work, but they’re not fully functional. He can respond to discomfort, pain, and minor disturbances and cry or whine to inform you.
His body temperature is far lower than a mature dog's, and he can’t handle cool weather. To help with ideal development, the room should be kept quite warm (around 80 degrees), and breeders achieve this through the use of heating pads and/or heat lamps.
Newborn pups need their mother to stimulate the defecating and urinating process as they can’t do it for themselves.
A puppy's first goal in life is to find food and warmth. Although they don’t yet have teeth, their nails are fully grown and might need to be trimmed within the first week of birth.
Their main activities are to look for nourishment from their mother and also to sleep as much as possible.
Newborn pups usually sleep, sometimes twitching or moving slightly to change position. The twitching happens because their main sleep is REM sleep, a level caused by higher brain activity.
Apart from that, they don’t interact with others in the litter or their surroundings except to huddle as close as possible to their mother and littermates to keep warm.
Pomeranian pups rely on the mother to supply nourishment and help them go potty. The mother also has to clean up the potty messes, which she happily does.
Puppy’s eyes start opening when they’re about two weeks old. A couple of days after that, their ears also open. Their sight is blurry at first but soon settles, and they can take their first view of their environment. Sight doesn’t get very sharp even as they start growing into adulthood.
After their ears open, they may get startled by different sounds around them. Even when their ears start working, they can hear the ultrasonic range, and their range is almost twice the capacity of humans.
3 to 6 Weeks Puppy Growth
At three weeks, puppies will become a bit adventurous and start to move around, albeit clumsy. This can be likened to a human infant’s crawling period. At this time, progress happens quickly. By 3 ½ weeks, most puppies are stable and can move around independently.
Hearing and sight improve each day. They can start to drink liquids and eat mushy solid foods. They will have some interaction with others in their litter, but most of this will be deciding who will act as a blanket as they sleep in a pile and cuddle up underneath.
However, they don’t mind either role. This is also the time when they first start socializing. With open ears and eyes, they crawl a lot more and even begin trying to stand up and walk properly.
By the time they’re four weeks old, they know what “real” puppy food is, eat more of such foods, and reduce their nursing.
They’re not weaned at this stage. Pomeranian pups sleep less and spend more time moving around. At this point, they begin to socialize with the world around them.
They should listen to sounds like the vacuum cleaner, dishwasher, can opener, and hairdryer. They should listen to the TV or music as well.
This is the perfect time for the puppy to walk on different textured surfaces such as grass, tile, wood, dirt, carpet, and concrete.
Additional textures can be added to his bedding, and the breeder can wear different textures in clothing so the puppy can snuggle up and feel them for himself.
The puppy is starting to control his body temperature, develop a puppy coat, and do his business without stimulation from the mother.
However, she’ll keep cleaning up after him for a bit longer. At the five-week point, he’s now considered a toddler and will spend much time mixing with humans, his mother, and litter mates.
If he has toys, he’ll explore them, but they won’t be an object of vigorous play until he’s a bit older. The mother will encourage her little to wean by being unavailable for drinks whenever they desire.
Puppies begin to “play fight” with their mates but are still too young to work out their pecking order and temperament. Some mothers regurgitate food for the puppies, but this doesn’t often happen in domesticated dogs.
Playtime changes dramatically at this stage, and toys become objects of pure fascination and delight. Puppies will find different ways to explore every possible corner of their surroundings.
Breeders should offer plenty of stimuli regarding smells, sounds, and textures and vary the environments where puppies can safely explore. The mother will keep teaching manners, particularly regarding “bite suppression.”
Puppies will gradually learn what is and isn’t appropriate canine behavior. These behaviors will continue for two weeks until they’re completely weaned and can be taken to permanent homes. Smaller dog breeds like Pomeranians might need extra time with the litter and mother.
At six weeks, a puppy is outgoing, friendly, curious, and eager to learn. If socializing is handled properly, the puppy will be keen to please his new owners when that time arrives.
8 Week Old Pomeranian Puppy
At the eight-week-old mark, many smaller breeds are prepared to be taken to their permanent homes. Other types may need as much as four more weeks in the breeder's and mother's care, especially if the puppies are the tiniest Pomeranian pups.
When the puppy is eight weeks old, he starts to exercise caution in his behavior. Before this, he would be reckless and exuberant, running headlong into any adventure fearlessly.
During the following two weeks, he becomes more cautious as he investigates everything around him. New owners must let him go through this stage because he’ll move past it quickly.
During this time, pet parents shouldn’t baby and cuddle” the puppy. Instead, they can assure his safety without moving in to rescue him when it’s not needed.
Anxiety and fear issues may arise in puppies who get rescued too early, which can be difficult to correct down the track. When a puppy is taken to his new home, his first few nights can be hard because he hasn’t spent much time alone.
3 Month Old Pomeranian Stage
Socialization is critical during this period and should be maintained. Even before he’s brought home, the home must be ready for his grand arrival.
This includes puppy-proofing all rooms of the house and ensuring he has everything necessary to enable him to feel comfortable.
The puppy should be exposed to as many new smells, sounds, sights, and sensations as possible. The more stimuli and experiences he faces, the easier he handles changes as he ages. This is also an ideal starting point for training.
Potty training is the first essential focus, followed by basic commands. Teaching basic obedience skills is best commenced in the home, and down the track, he can be enrolled in an obedience school after he has been immunized and is ready for that next phase.
Immunizations Are Critical to The Health Of All Young Puppies
They must be a top priority, even over socializing attempts. A puppy can’t go into dog parks until he has received his shots. Consider a puppy in a similar vein to a newborn infant baby. If you wouldn’t do something to an infant, why would you do it to a puppy?
The puppies are now in the “tween” phase, exhibiting some examples of independence. It’s likened to the pre-teen stage in humans and is demanding in nature.
Instead of the puppy sticking to you like glue, he’ll wander off to do whatever he wants. Puppy’s behavior is more erratic, and he may be a cute little baby one minute and the most stubborn of tweens the next.
This is the point when teething sets in, and he’ll look to find anything he can chew on, including toys, a wooden chair, and even a person’s toes or fingers.
He should start being potty trained and basic obedience training, such as how to walk properly on a leash, not always by your heel.
At this point, his growth spurt should slow down, and he may eat less food. At the end of this stage, the puppy must have had his third round of shots and a Rabies shot as well.
Once vaccinated, it’s a perfect time to take the puppy exploring. Take him whenever you go out (if possible). It’s also good to start teaching basic commands.
6-Month-Old Pomeranian Puppy Stage
Congratulations, your fur child has finally reached his teenage years. His attitude is everything now. He’ll try breaking rules and testing boundaries when he sees chances to do so.
He won't become a juvenile delinquent if you have been training and socializing with him. He can go to puppy classes and learn more commands.
His baby teeth will fall out, replaced by a full mouth of adult teeth. Dental care is critical from this point on. Puppy will be at the sexual maturity stage at some point in this time. It’s wise to have her spayed or neutered.
Most vets recommend doing this by the age of six months. A puppy needs lots of chew toys, exercise, and discipline. Patience will be your new best friend.
1 Year Old Pomeranian
After this stage, the puppy is now an adult dog and is sexually mature. Smaller breeds will be their full adult weight, Pomeranian size, and height. If spaying or neutering hasn’t occurred, there will be visible signs of sexual maturity.
Pomeranian Sexual Maturity?
Is my Pomeranian in heat? Females will have had their first heat between 6-9 months old. If the males haven’t been neutered, they will commence displaying sexual behavior and mark their territory. Males may be fathers when they’re as young as seven months of age.
Final Thoughts on Pomeranian Puppy Growth Stages
There won’t be visible changes immediately, and Pomeranians often retain a playful personality for most of their life. Over time, their youthful exuberance will fade, and (provided you did socialize and train properly) the dog will become calmer and behave more predictably with the same habits.
