When Do Japanese Spitz Stop Growing?

From birth to adulthood, a Japanese Spitz puppy develops at a rate of around 12-14 months. Due to their diminutive stature, they mature more quickly than other breeds.

The optimal period to get a Japanese Spitz puppy is between 6 and 8 weeks after birth. You could wait until they are closer to 10 weeks old, but this is not recommended.

There is no reason to delay your puppy's first veterinarian visit. When the time comes for your puppy to visit a veterinarian, you should not waste time. The longer you wait to take your puppy to the veterinarian, the more susceptible your puppy becomes to numerous health problems caused by viral and bacterial infections.

How To Weigh Your Japanese Spitz Puppy?

If you want to maintain track of your Japanese Spitz's weight, you must first learn how to weigh him properly.

To begin, you should be able to weigh your Japanese Spitz at home if he is a puppy or if you are just large enough to hold him. This can be accomplished with a standard bathroom scale.

To begin, weigh yourself and record the result. Then, while standing on the scale, pick up your dog and hold him. The difference in weights represents your dog's weight.

If your dog is too huge to carry, you can either invest in a dog scale, which can cost upwards of $100, or contact your veterinarian. The majority of veterinarian offices will enable you to use their scale.

Unless there is a health problem, you can weigh an adult Japanese Spitz once every six months. Once a week is sufficient for a puppy to ensure he is growing normally.

What Is A Japanese Spitz’s Neck Size?

To determine the neck size of your dog, use a soft and flexible tape measure to determine the neck size of your dog where her collar naturally falls. Then, put two fingers between your dog's neck and the tape measure to ensure that the dog collar fits snugly but comfortably. Japanese Spitz's average neck circumference is between 10 and 14 inches.

How Big Do Japanese Spitz's Get?

The average adult Japanese Spitz stands 12 to 16 inches (30 to 40 cm) tall at the shoulder, with males standing approximately an inch taller than females. Adult Japanese Spitzes typically weigh between 15 and 30 pounds, or 7 and 13.5 kg. This is strongly dependent on the height and body type of the animal.

This categorizes the Japanese Spitz as a “small to medium size dog,” which encompasses all breeds weighing between 0 and 25 kilograms, or approximately 11 kg.


Factors That Affect Japanese Spitz Puppy Growth 


Genetics and gender are the two most important factors that will determine the size of your Japanese Chin puppy. Genetics comes into play when determining the size of your pup's parents.

If they were larger Japanese Chin dogs, your puppy will almost certainly be larger as well.

Additionally, male dogs are larger and heavier than female dogs, which means that a male Japanese Chin puppy will develop into a larger dog than a girl.

Diet & Nutrition

It is a frequent misperception that nutrition will affect your dog's eventual size. Consider that a Havanese puppy will mature into an adult quite rapidly, and the amount of nutrients he receives is highly unlikely to have an effect on his eventual size.

Nutrition is still critical for your dog's overall health and longevity, but it is less likely to affect his size.

Physical Activity & Health

Physical activity is critical for all dogs, regardless of size. While activity has no effect on your dog's skeletal growth, a lack of activity or bad health may result in your dog being overweight.

If this is the case, it can be difficult to motivate an unhealthy, overweight dog to reduce the weight you desire. This will have an effect on his joints and may impair his mobility as he ages.

Common Questions about Japanese Spitz

At What Age Is A Japanese Spitz Fully Grown?

From birth to adulthood, a Japanese Spitz puppy develops at a rate of around 12-14 months. Due to their diminutive stature, they mature more quickly than other breeds.

Spitzes grow rapidly in height and length throughout the first six months of their lives, before plateauing as the adolescent puppy gains muscular mass; Spitzes are typically at or near full size by the time they reach the age of 10-12 months.

On the social front, things are also moving along slowly. In general, puppies reach puberty relatively early, usually between 3 and 4 months.

How Long Are Japanese Spitz Pregnant?

Pregnancy lasts an average of 60 to 64 days in a Japanese Spitz. Pregnant or lactating Japanese Spitzes exhibit the following characteristics:

Appetite loss

Vomiting is frequent throughout the first trimester of pregnancy.

They may appear lethargic, and their energy reserves are constantly exhausted.

As with other breeds, they go into heat or sexual maturity twice a year and will remain in that mature state for approximately 3 weeks.

This also holds true for all dog breeds. If your female Japanese Spitz is in good health, she will go into heat every six months. Age is also a factor in canine heat.

As a result, as they age, their heat phase may become less common. Additionally, they may experience what is referred to as “silent heat,” which is defined by the absence of bloody discharge from their vulva. Therefore, even in the absence of bloody discharge, they are still in heat.

The canine heat cycle lasts around 18 to 21 days and is divided into four separate periods. Experienced dog breeders use these stages to determine the optimal time to mate their canines, ensuring successful coitus or intercourse between the dam and sire. While the dam is in heat, she can breed with multiple males (sire).

How Many Puppies Do Japanese Spitz Have?

Japanese Spitz dogs have an average litter size of between one and six puppies. Given their petite stature, it makes natural that their bodies are limited to producing puppies up to that amount.

Having more than six puppies in the womb of this dog breed may endanger both the dam and her unborn puppies. Fortunately, this situation occurs infrequently in Japanese Spitzes.

If your Japanese Spitz dam is well cared for during her pregnancy, is in good condition, and is still relatively young (between 3 and 6 years old), there is a good chance that her litter will be healthy and powerful. As a result, the puppies have a good probability of survival following birth.

What Is The Life Expectancy Of Japanese Spitz?

Life expectancy is estimated to be between ten and sixteen years. As a result, it is one of the most enduring dog breeds.

How Much Does It Cost To Own A Japanese Spitz?

You should budget approximately $1,500 for a Japanese Spitz without breeding rights. Due to the likelihood that you will be unable to visit a breeder, you may be required to pay an additional $500 to ship the puppy to you. If you desire breeding rights, be prepared to pay a premium.

How To Help Your Japanese Spitz Lose Weight If He Is Overweight 

As with humans, exercise is critical for your overweight dog's health. Increased movement helps your dog burn off excess energy (and calories consumed). Avoid panic! Exercising your pet does not have to include marathons or lengthy hikes. Regular walks and the opportunity to run and play safely off-leash. 

Even creating a stimulating indoor environment that encourages your dog to exercise on a regular basis can help. Bear in mind that different breeds require varying amounts of exercise, so visit your veterinarian, breeder, or your dog's breed standard for recommendations on recommended activity levels.

Distinguish Begging from Hunger

Begging is not necessarily motivated by a desire for more food; it is also used to gain attention. (And, by rewarding the behavior, you reinforce and encourage it to continue.) If your dog begs, do not automatically assume he is hungry. Trust your instincts and keep track of the date and time of your last meal.

If your dog is prone to begging and you are prone to succumb to those puppy dog eyes, choose a high-protein meal with a fiber blend to help control your dog's hunger and voluntary food consumption. In this manner, you may feed your dog with the assurance that he will feel fuller and content for a longer period of time.

Restriction on treats and table scraps

Even when our dogs are not begging, many of us provide an excessive amount of treats and table scraps. Dogs are not required to share our food! Consider treats and scraps for your pet in the same way that you would candy for children to help you keep them in check. If you're going to utilize snacks for training, choose low-calorie, low-fat ones and keep the portions small. 

As an alternative, keep in mind that clickers are excellent for reinforcement… and they have no calories! After all, a few extra pounds can make a significant impact in the lives of dogs, which are significantly smaller than humans. (Even the colossal breeds!) Therefore, focus on a balanced diet and resist the temptation to “reward” them with extra.

Customize Your Dog's Diet

Not all weight-loss foods are created equal, which is why it's critical to match your dog's nutrition plan to their unique needs. Choose a brand that caters to your dog's unique needs, whether they be weight control, dietary sensitivities, or illnesses.

Conclusion on Japanese Spitz Growth Chart

These puppies should, in general, have a V-shaped black brow. Adult Japanese Spitz ears should be alert, yet the fur should be soft and not coarse.

If the puppy is less than five months old, evidence of improper color or shape may still be visible. As a result, do not consider such to be signs of something wrong with your dog. There is no cause to be alarmed if their ears do not entirely stand upright during the first five months of life or if their muzzle appears somewhat longer. Typically, these puppies' coloration will not be full until they reach the age of four or five.
