Akitas generally take a bit longer to develop into their full adult size. This is typical for large breed dogs that need more time to grow than smaller-sized dogs do.

Most Akitas will reach close to their full size by the time they are approximately 10 months old. However, until they reach the age of two, they will continually gain weight. 

The size of your Akita really depends on their age and their lifestyle. The foods they eat and level of physical activity, play a major role in their weight and health at any given time.

Another way to check your Akita’s development is to look at their paws. If their paws still look too big next to the legs and body, then they most likely have a lot more growing to do as this is a characteristic of a puppy.

Looking at an Akita growth chart should give you a good idea about your dog’s expected weight.

Akita Growth Chart – What To Expect

When Do Akitas Stop Growing

Birth – 2 Weeks 

Akitas are born in a delicate state as they are can’t look after themselves. They depend on their mother for warmth comfort and nourishment. 

Newborn puppies require an optimal temperature to survive. They snuggle close to their mother, but they can’t walk yet because of their undeveloped muscles. The puppies need this time with their mothers so that they may grow.

3 Weeks – 12 Weeks 

Between 3-12 weeks, your Akita will go through many changes, as their muscles begin to get stronger. They are fully weaned at around 28-30 days old, and they have a full set of sharp teeth.

Most mothers would start weaning them soon enough on their own. 

4 Months – 9 Months 

During this period, the Akita pup will go through teething. At 6 months, the Akita female weighs on average between 50 pounds for the smallest dogs and 65 pounds for the largest dogs.

At 6 months, the Akita male weighs on average between 55 pounds for the smallest dogs and 70 pounds for the largest dogs.

10 Months – 18 Months 

This is an important stage. The heat cycle will last for about 21 days, and the females are fertile at this time, but it is not advised that she gives birth before two years of age.

Young dogs are not emotionally and physically ready to give birth because they have not finished their development.

It can be very dangerous for your Akita to get pregnant during this stage and if they are, there can be issues with the pregnancy, death of pups, and even birthing complications which can lead to organ failure as well as the death of the mother.


The Akita male and female will end its growth at 2 years. The common size of adult Akitas is approximately between 70 and 100 pounds for females and 100 to 130 pounds for males.

A full-grown Akita is usually compact and muscular, with commanding stature. Overall, they are well-balanced and tend to be longer than tall. Until they are two years old, many Akitas will continue to fill out their chests and gain muscle.

How Big Do Akitas Get

You probably already have a good idea about how big an Akita gets just by looking at a growth chart. But, there are some other tricks that you can use to get an idea of what you will expect as your dog gets bigger.

The easiest method is to look at your dog’s parents. Dogs often are similar in size to their parents, so if their size matters. You can also look at your puppy’s paws.

Dogs have to grow into their paws, so big paws mean the dog will be big. Finally, you can get a DNA test to see what the pup’s genetics has to say about his size.

American Akita vs. Japanese Akita 

There are two types of Akita dogs. There is the Japanese Akita and the American Akita. They will both grow to be around the same size, but they can have different coat colors.

The American Akita and the Japanese Akita Inu are two separate breeds that can be differentiated by color, body shape, size, and personality.

When it comes to height, Akita Inu females are around 23 to 25 inches and males are around 25 to 28 inches. For the weight, females are about 50 to 65 lb and males are 70 to 85 lb.

Akita Size Chart 

We spend a lot of time talking about how much an Akita puppy weighs, but we often leave out how tall an Akita is. On average, an adult male Akita is between 25 and 28 inches in height.

Meanwhile, an adult female Akita stands between 22 and 25 inches tall, showing that the height difference between the sexes is noticeable.

To measure your Akita’s height, have him stand on all four legs. Then measure from the high point on his back, known as the withers, down to the ground. This will give you your dog’s height.

Will Neutering/Spaying Affect My Akita’s Growth? 

If you have an Akita puppy and have no thoughts about breeding your puppy or taking him to dog shows, then you should be considering having your dog spayed or neutered.

It is a common and safe procedure that will prevent your dog from being or causing pregnancy and will also stop him from running off in search of a mate.

But, in more recent years, there has been a concern about how sterilizing your dog will affect his growth.

It turns out that in large breed dogs, early sterilization can cause a disruption in their joint growth, making them have mobility issues later in life. It is better to wait until your dog has finished growing before having the surgery performed.

How To Properly Weigh And Measure An Akita? 

If you are looking at the growth chart for an Akita and wondering how you can know how much your dog weighs, we have some suggestions for you.

The first thing to remember is that Akitas are not small dogs, so the way that you can weigh them is not always easy.

When your Akita is a puppy and you can still hold him, you can just use a common bathroom scale to get a weight. You should do it weekly. To use this method, you just weigh yourself, then weigh yourself again holding the puppy.

The difference in weights is your dog’s weight. When the dog gets bigger, you might need to take your dog to the vet for weight checks, unless you want to invest in a large scale for your house.

What Is An Akita’s Neck Size? 

When we are talking about a dog’s measurements, a dog’s neck size is the last thing anyone is thinking of.

But, it is still important that you take a measurement of your Akita’s neck. This is used most often to help you buy an appropriate collar for your dog.

The average size of an adult Akita’s neck is between 14 and 20 inches, but a puppy’s will naturally be smaller. You need to expect to replace a puppy’s collar at least once, if not twice. The more adjustable the collar, the longer the collar will last.

Akita Body Condition Score (BCS) 

When it comes to determining whether your dog is an appropriate weight, there is a handy scale that you can use. The scale is not based off of your dog’s breed or weight, but it is based on the look and feel of your dog.

The scale is called the Body Condition Score (BCS). The scale works from a 1 to 9 score, with 1 being the lowest and 9 being the highest.

1 refers to a dog that is emaciated, underweight, and very bony. A dog with a BCS of 1 is very unhealthy and needs to gain weight.

On the other end of things, you have a 9. A dog with a BCS of 9 is a dog that is overweight. You cannot see the dog’s waist, his sides are bulging out, and there is no way to see or feel his ribs.

The ideal BCS score for your Akita is a 5, which is where you cannot see a dog’s ribs, but you can feel them easily. You should also be able to see your dog’s waist if you are looking at him from above.

How To Help Your Akita Lose Weight If He Is Overweight 

If your dog does have a higher BCS, there are some things that you can do about it. It is ideal to avoid having your dog be overweight, but there are some things that you can do to help your dog out.

  • Cut down on treats. The first thing to do is to cut down on dog treats. If you have been giving your dog table scraps, it is time to stop. Your dog also does not need treats all of the time. These are just empty calories.
  • Bump up the exercise. The next thing to do is to bump up the amount of exercise your Akita is getting. If he is severely overweight, you need to do this slowly in order to prevent injuries. Don’t overdo it and exhaust your dog.
  • Look at his food. Finally, you should look at the food your dog gets. Is it healthy? Is it full of fillers? You might want to switch to a food that is full of protein and vitamins.

Factors That Affect Akita Puppy Growth

Akita Growth Factors


Genetic factors greatly affect an Akita’s growth. These hereditary factors determine the growth rate as well as other essential factors that add to their development.

For example, if both parents are large, then the offspring will be also. The fully grown dog will be approximately the average of the parents’ sizes. 


The type of nourishment given to your Akita puppy will affect his ability to grow. More nutritious food gives your dog all the nutrients that it needs to grow larger and stronger.

You may have to give supplements to your Akita for his health. These are in cases when your dog may be grossly underweight or malnourished to help them to grow to their average height and weight.

Physical Activity & Health

Akitas were bred to be hunters so if they don’t get enough exercise they will not be able to meet developmental milestones. Sufficient exercise is required to promote growth and allow bone density to be developed.

Your Akita will have healthy strong muscles when he is allowed to exercise regularly. It’s important not to overdo it because Akitas who exercise too much may suffer damage to the growth plates. This injury may inhibit their growth and cause them to be smaller than usual.

How Long Are Akitas Pregnant? 

For Akitas, the normal gestation period is about 58-63 days from conception, but this can vary by several days.

You should always check with a vet because conception is often difficult to pinpoint. This is because the sperm can survive for numerous days within the female, and eggs can remain fertile for up to 48 hours.

Therefore, the mating date is not an accurate measurement of gestation. This makes it difficult to determine the length of pregnancy without the assistance of a veterinarian.

Akitas are generally full-grown and ready to reproduce when they are at least two years old when they are bred for the first time. The suggested upper limit for breeding your Akita is the age of seven.

To protect your Akita’s health, there should be at least one year between successful mating sessions. Additionally, no Akita should be pregnant more than three times in her lifetime.

Female Akitas enter their heat cycle about once every six months. It lasts approximately three weeks or so. If your Akita is bred outside the 2-7 year time period, there can be issues with the pregnancy.

As your Akita gets older, she runs the risk of having health problems such as hip dysplasia, immune disorders or hypothyroidism that can complicate pregnancy causing loss of the pregnancy or extreme pain.

What If My Akita Is Not The Right Weight 

As a general average, female Akitas will weigh between 70 and 100 pounds while their male counterparts will weigh 100 to 130 pounds. They are a large breed dog that is especially lean and agile.

A significant part of his weight should be comprised of lean muscle. Therefore, Akitas is at a healthy weight and may seem leaner when compared to other breeds. 

Akitas have hearty appetites and will gain weight if their diet is not correctly controlled. You should focus more on proper diet and sufficient exercise to have a healthy dog. It is also good to consult your vet and Akita weight chart if you are unsure about his weight.
