Japanese Spitz Growth
Did you just get the Japanese Spitz puppy? And do you want to know when your Japanese Spitz will stop growing and how big your Japanese Spitz will get? Or do you want to know if your Japanese Spitz is of the ideal weight for its age?
In this article, we will answer all relevant questions related to Japanese Spitz growth and weight.
If you do not own the Japanese Spitz yet, make sure you purchase your Japanese Spitz from an ethical Japanese Spitz breeder or work with a reputable rescue. Check out our Japanese Spitz buying guide and Japanese Spitz price guide here.
It is important for you as a caring Japanese Spitz owner to know if your Japanese Spitz is growing normally and if your Japanese Spitz is not overweight or underweight.
Extensive research studies have shown that most dogs are overweight because their owners spoil them with food, treats, and an easy life. Most dogs eat way too much and do not get enough exercise. Research has also shown that one of the reasons many dogs die young is because they are overweight. You can extend your dog`s life by making sure your dog is of healthy weight and growth.One final reason to keep track of your Japanese Spitz`s weight and growth is that your Japanese Spitz`s weight and growth pattern can tell you if your Japanese Spitz has some underlying health conditions (such as bone, heart, hormone diseases). This is what recent research has shown.
This article contains the Japanese Spitz growth calculator that you can use to predict your Japanese Spitz`s adult weight. This article also contains the Japanese Spitz growth chart and weight calculator that you can use to approximately tell if your Japanese Spitz`s weight is in the normal range based on its current weight.
However, the more accurate method to predict and track normal growth in your Japanese Spitz is by regularly weighing your Japanese Spitz and recording the weight of your Japanese Spitz with our free dog weight tracker and weight predictor. Our tool will tell you, first, a more accurate future weight of your Japanese Spitz and, second, if your Japanese Spitz is growing normally.
We designed our dog weight tracker and weight predictor based on a recent research study carried out by researchers from Banfield Pet Hospitals and the University of Liverpool. This study collected and analyzed the weight of over 6 million healthy dogs in the United States. The dogs studied included dogs in the Japanese Spitz weight category.

Japanese Spitz Growth Calculator
Use the calculator below to estimate how big your Japanese Spitz will get based on its current weight.
This Japanese Spitz growth calculator is based on the typical weight curve of a Japanese Spitz shown above. The calculator assumes that your Japanese Spitz is growing normally, and not on its way to become overweight or underweight.
How Much Should a Japanese Spitz Weigh?
Japanese Spitzs typically weigh between 11 to 20 pounds.
Above is a graph that shows how much a Japanese Spitz should weigh at different ages. Check where the weight of your Japanese Spitz falls in the graph for its age.
The weights in the dark green region is typical for Japanese Spitzs.
If the weight of your Japanese Spitz falls outside the dark green region for its age, then you should consult a vet.
Also, you can use the Japanese Spitz weight calculator below to find the typical weight and the normal weight range of Japanese Spitzs, male or female, of any age between 12 weeks and 100 weeks.
If you want to see how the weight of your Japanese Spitz compares to that of other Japanese Spitz`s of its age, enter the weight of your Japanese Spitz in the calculator, and the calculator will show you where your Japanese Spitz stands on the weight chart.
The calculator will also tell you if your Japanese Spitz is within the normal weight range for the Japanese Spitz.
This Japanese Spitz weight calculator uses information from a research study on dog weight carried out by researchers at the University of Liverpool.
Please, talk to your vet before taking any decision on your pet`s weight and health.
What is the Height of the Japanese Spitz?
The adult Japanese Spitz is 10 to 16 inches. This is the average adult height of the Japanese Spitz.
Is Your Japanese Spitz Growing Normally? This is How to Tell
Puppy growth predictors, growth charts, and growth calculators like the ones above are approximate methods for predicting growth in dogs. However, these tools have limited capabilities. This is because each dog is unique and a dog`s growth may be different from that of the overall dog population.
A more accurate and scientific way to predict a dog`s growth is to measure the dog`s weight every week and record the weight. Doing this with your Japanese Spitz will give you a clearer picture of how your Japanese Spitz is growing.
You can use our free tool to track your Japanese Spitz`s growth and weight over time. Our tool will also let you know if your Japanese Spitz is growing normally.
Tracking your Japanese Spitz`s weight will let you see the unique growth trajectory of your Japanese Spitz. You can use this growth trajectory to accurately predict how big your Japanese Spitz will get. The growth trajectory will also let you know very early if your Japanese Spitz will become overweight or underweight.
Monitoring your dog`s weight is important because pet obesity is one of the leading causes of premature death in dogs. And these days, pets gain weight very easily because their owners spoil them with lots of treats and food. Catching early abnormal weight in your dog and correcting it (through diet changes, exercise) can significantly extend your dog`s life.
Below is what a normal growth pattern and what abnormal growth patterns look like in Japanese Spitzs. You can compare your Japanese Spitz growth trajectory against these references to see if your Japanese Spitz is growing normally or you can use our automatic tool.
How to Measure the Weight of your Japanese Spitz
There are two methods you can use to measure your Japanese Spitz`s weight.
The first method, which is the better and more accurate method to weigh your Japanese Spitz, is to use a dog weighing scale.
Using a dog scale is important if you would like to monitor your Japanese Spitz`s growth regularly to catch any abnormal growth early.
Having a scale for weighing your Japanese Spitz will make it easy for you to weigh your Japanese Spitz regularly without any trouble.
The scale that we recommend for weighing the Japanese Spitz is this high durability and affordable Greater Goods Digital Pet Scale. Click here to check out this scale on Amazon.
The second method is to use a bathroom scale to weigh yourself while holding your Japanese Spitz. Then use the same scale to weigh yourself without your Japanese Spitz. Then calculate your weight when holding your dog minus your weight when not holding your Japanese Spitz. This method is illustrated in the picture below.
However, note that this method of holding your dog on a scale is not very accurate, and it may be difficult for you to use this method to weigh your Japanese Spitz if your Japanese Spitz is very heavy or if your Japanese Spitz is the type that would not stay still while being held.
How Fast Do Japanese Spitzs Grow? Japanese Spitz Growth Rate
Starting from 3 months of age, Japanese Spitzs grow at a rate of 0.44 pounds per week (0.20 Kilograms per week) on average. Starting at 4 months, your Japanese Spitz will gain 0.36 pounds (0.16 Kilograms) every week on average.
At 5 months of age, your Japanese Spitz will grow at a rate of 0.30 pounds per week (0.13 Kilograms per week) on average. Then at 6 months, your Japanese Spitz will gain 0.24 pounds (0.11 Kilograms) every week on average.

| 3 Months | 0.44 | 0.20 |
| 4 Months | 0.36 | 0.16 |
| 5 Months | 0.30 | 0.13 |
| 6 Months | 0.24 | 0.11 |
| 7 Months | 0.19 | 0.09 |

Japanese Spitz Growth Stages
Your Japanese Spitz will go through a number of developmental stages on its journey to adulthood. Your Japanese Spitz`s growth pattern can be categorized into 6 distinct stages: Neonatal, Transitional, Socialization Period, Juvenile Period, Adolescent Period, and Maturity.
You can know the developmental stage of your Japanese Spitz based on how old your Japanese Spitz is.
1. Japanese Spitz Neonatal Period
Japanese Spitz Neonatal Period is from Birth to 2 weeks. During this stage, the Japanese Spitz puppy will be totally dependent on its mother. The Japanese Spitz puppy`s eyes will still be unopened with no sense of vision. The Japanese Spitz puppy will only have the senses of taste and touch
2. Japanese Spitz Transitional Period
Japanese Spitz Transitional Period is from 2 weeks to 3 weeks. During this stage, the Japanese Spitz puppy will continue to develop a better sense of hearing and taste. The puppy`s teeth will start coming through and its eyes will begin to open.
During this stage, the Japanese Spitz puppy begins to crawl forward and backward, begins to stand, begins to wag its tail. This is also the age where your puppy’s personality begins to develop.
3. Japanese Spitz Socialization Period
Japanese Spitz Socialization Period is from 3 weeks to 14 weeks. During this stage, the Japanese Spitz puppy will be able to fully use all of its senses (vision, smell, touch, hearing, taste), and the puppy will learn to survive without its mother.
Also during this stage, the Japanese Spitz puppy learns how to act like a dog (biting, chasing, barking, etc). The rapid learning and socialization of the puppy occur at this stage, and what the Japanese Spitz puppy learns in this stage will have a long-term effect on the puppy`s behavior as an adult.
4. Japanese Spitz Juvenile Period
Japanese Spitz Juvenile Period is from 3-4 Months to 5-14 months. During this stage, the Japanese Spitz puppies will attempt to clarify and resolve their boundaries. Their baby teeth start getting replaced by adult teeth.
5. Japanese Spitz Adolescent Period
Japanese Spitz Adolescent Period is from 5-14 Months to 2-3 Years. Japanese Spitzs go through social and sexual maturity during this stage.
6. Japanese Spitz Maturity Period
Japanese Spitz Maturity Period is from 1 year to 4 years. At this age, your Japanese Spitz will transition to full adulthood.

How to Tell If Your Japanese Spitz is Overweight
As mentioned earlier in this article, a very accurate way to know if your Japanese Spitz puppy is on its way to becoming overweight is by weighing your dog every week and recording its weight. This will show you the growth trajectory of your Japanese Spitz puppy. And a close look at your puppy`s growth trajectory will tell you if your Japanese Spitz puppy will be overweight or underweight. This method is relatively easy to use.
You can use our free online tool to track your Japanese Spitz puppy`s growth curve.
However, if you do not have a record of the weekly weights of your Japanese Spitz, and you want to tell if your dog is overweight, underweight, or of normal weight, then you can use a chart called the body condition chart shown below. This method requires some expertise to use, and it is further discussed below.
To tell your dog`s body condition, first, look at your dog closely and observe which of its bones and structures are sticking out or not sticking out from under its skin. Next, use your hands to feel for fat and bones over your dog. To know which bones to look and feel for, check out the body condition tool guide from the World Small Animal Veterinary Association and this guide. This exercise will tell you the body condition score for your dog.
Body condition scores are from a scale of 1 to 9. A score of 1, 2 or 3 means that a dog is too skinny. A score of 4 or 5 means that a dog is of ideal weight, and a score above 5 means that a dog is overweight.
Talk to your vet if your Japanese Spitz appears to be overweight. The vet might recommend reducing how much food to feed your Japanese Spitz.
Conclusion on Japanese Spitz Weight and Growth
In this article, we have provided you with the information, growth charts and growth calculators to help you tell how big your Japanese Spitz will get. These tools will also help tell if your Japanese Spitz is growing normally.
However, the best way to monitor and predict the growth of your Japanese Spitz is to measure and record your puppy Japanese Spitz`s weight every week.
Use our free Japanese Spitz weight tracker and calculator tool available here to track and predict your Japanese Spitz`s weight.
It is important that every Japanese Spitz owner monitors the growth of their Japanese Spitz for normal growth by checking the weight of their Japanese Spitz regularly. Regular weight monitoring will let you detect any abnormal growth very early before it is too late. We discussed how you can tell if your Japanese Spitz is growing normally from your Japanese Spitz`s weight history earlier in this article.
Abnormal growth in Japanese Spitz can be because of underlying disease (such are heart, hormonal, or bone problems) or because of overfeeding or underfeeding. All of the aforementioned reduce the Japanese Spitz lifespan and quality of life.
