It is always a joy to watch puppies grow, especially fast-growing pups like Boxers. Boxers are not only cute dogs to raise but also great pets that can socialize, guard, and hunt.

But how do you know your Boxer dog is growing properly?

Just like other dog breeds, Boxers grow at different rates. If you want to become a parent of a new puppy, it’s important to research their weight, height, and temperament before rehoming.

Luckily, this guide has all the detailed Boxer charts that will serve as handy references you can follow with ease. These estimates can guide you on how big your dog can get.

Below is a detailed chart showing the ideal weight of male and female Boxer dogs depending on their age:

There are several factors that can help or stop your Boxer’s growth, and one of them is proper nutrition. 

Remember to give them food that can provide extra vitamins and minerals as well as a complete set of nutrients they need.

If your dog is drastically gaining or losing weight and is growing too fast or too slow, you better contact your local veterinarian because your pooch may be suffering from growth hormone deficiency.

Other than that, Boxers who grow slightly more or less than the estimated numbers on the chart are generally safe. These numbers are only estimates, and changes are only alarming when it is extreme.

However, take note that these apply to the standard Boxer. A miniature version of the Boxer exists, whose size may fall below the numbers given and follows a different set of standards for its ideal weight.

At What Age Are Boxer Dogs Fully Grown?

A Boxer puppy reaches its adult weight and height between 18 and 24 months old. Because Boxer dogs are medium-sized dogs, they need more time until their height and weight reach their full potential.

Do not panic if your Boxer hasn’t fully developed at the said age because every Boxer pup differs slightly. 

For instance, while male and female Boxers reach their full growth at the same time, some may grow slower than others.

Additionally, asking your trusted breeder about the puppy’s parent’s growth will give you a clear idea about how fast and big your Boxer puppy can get. 

If you are unable to get this information from your dog’s breeder, a DNA test is a good option to know more about its genetics.

How Big Do Full-Grown Boxer Dogs Get?

According to the American Kennel Club (AKC) breed standard, a fully grown male Boxer with a healthy weight is expected to grow around 23 to 25 inches tall and weigh an estimated 60 to 70 pounds.

On the other hand, an adult female Boxer may grow over 21.5 to 23.5 inches tall and weigh 55 to 65 pounds at 24 months of age. Boxer dogs go through several stages before they become adult dogs.

In terms of length, Boxers can range from 30 to 35 inches long, measured from the back of their hind legs up to the tip of their muzzle, parallel to the ground.

Even though most Boxers are medium-sized dogs, they can still grow from medium to large depending on their growth spur. The size of the puppy’s parents can also be a determining factor.

How Do I Know How Big My Boxer Dog Will Get?

A dog’s age is the primary factor in its growth, and dog owners often wonder if their Boxer puppy is growing normally. Aside from referring to the Boxer puppy growth chart, there are many ways to know how big your Boxer dog will get.

You can use a puppy growth calculator, also known as a growth predictor, to determine a dog’s approximate height and weight. These tools may be recommended, but their capabilities are limited.

Boxer puppies grow differently from each other; therefore, tracking their weight and height every week is more accurate. Because this method is more systematic, it gives you a clear view of your Boxer dog’s growth.

One method of measuring their growth is by looking at the Boxer’s paws. To do this, simply observe their paws to see if they look bigger than their legs and the rest of their bodies.

If they are, then we can presume that your Boxer is still maturing. Although there are many ways to observe their growth, it is highly recommended for dog owners to study the Boxer weight chart.

Another way to keep your Boxer dog’s weight in check is to use a Boxer body condition score system. This method is basically calculating body mass index (BMI) for pets.

As an experienced dog breeder, one of the simplest ways I use to predict how big a Boxer puppy may grow is to check both of its parents. Along with proper nutrition and care, genetics will dictate that the puppy’s size will fall within the same range as its parents.

Similarly, I also check the previous litters of the parents as it would be a good indication of the dog’s future size as well.

Keep in mind that Boxer growth takes time, and they would require extra care as they develop. Failure to monitor your Boxer’s growth trajectory may lead to sudden weight gain or weight loss.

Boxer Dog Growth and Development by Age (With Pictures)

The Boxer dog goes through different stages of growth, in which the first stages are not as drastic as the rest.

Boxer dogs can look quite skinny during the first weeks of their life. However, this is not a cause for alarm because this is a temporary phase of their growth, and their growth process will eventually speed up. This means that their bodies will also keep up.

It doesn’t matter whether you are looking for a male or female Boxer puppy because both genders go through the same development stages. They may differ in height and weight, but they have the same growth process.

8-Week-Old Boxer Dog

An 8-week-old male Boxer puppy weighs 16 to 20 pounds, while a female Boxer puppy will weigh around 11 to 17 pounds. They are visibly small in size, and they will continue to grow at a fast pace.

Boxer puppies still need to rely on their mother’s milk until they are two weeks old. A Boxer puppy is weaned around the fourth week. It is around this time that dog owners change their pet’s diet to solid dog food.

After reaching eight weeks of age, a Goldendoodle’s weight increases by approximately 300%, and you can observe significant gains in their weight, as well as an increase in their appetite and energy levels.

12-Week-Old Boxer Dog

A 12-week-old Boxer puppy grows rapidly at an average of two pounds every week. Expect the weight of your Boxer to increase by 1.75 pounds and weigh up to 22 to 26 pounds for both male and female Boxers.

At this stage, your Boxer dog is already gaining most of its awareness and is starting to explore his surroundings. It is a good time to start researching how much exercise your Boxer puppy needs to maintain good health.

Your Boxer dog must be well-adjusted to solid food at this age. Keep in mind that the quality of dog food you give your Boxer is important. Make sure you give them food that promotes a healthy coat and good muscular development. 

16-Week-Old Boxer Dog

At 16 weeks, your Boxer puppy’s weight should be between 35 and 41 pounds. Their height does not grow as rapidly as their weight, so it’s perfectly normal for them to be the same height at four months.

What’s important is that they gain more weight. This period allows your Boxer puppies to fully transition into adults. Aside from the weight gain, Boxers also become increasingly more curious and independent.

They should also be able to completely eat solid food and maintain this diet to increase puppy weight. Because they are a medium to large breed, they change their diet as early as 16 weeks for optimal growth. 

You may observe your Boxer puppy roam around and sniff random objects and even enjoy time alone. Four months is also a good time to assess what physical activity Boxers can do.

6-Month-Old Boxer Dog

A male Boxer puppy should weigh over 41 to 48 pounds at six months of age, while a female Boxer weighs about 39 to 44 pounds. Some sources claim that puppies generally reach 75% of their growth at six months.

However, this may not be true for all dogs. For Boxer dogs, six months marks the time when they reach approximately 17 to 19 inches tall for males and 16 to 18 inches tall for females.

At this age, your Boxer puppy should already become active and playful. They may need to engage in more physical activities such as obedience training, running, or playing frisbee to regulate their physical well-being.

When playing outside, be cautious of larger dogs in the vicinity because your 6-month-old Boxer is not large enough to interact with them, and they may get injured. Playing with smaller dog breeds is perfectly fine.

9-Month-Old Boxer Dog

At nine months old, male Boxers are expected to weigh 52 to 61 pounds, while females fall slightly lighter at 52 to 59 pounds. Note that the female Boxer can grow at a slightly different pace from the male Boxer.

A Boxer dog will double their weight as early as four months. So, if your Boxer is in its ninth month, expect more weight gain. This is the perfect time to strengthen their body build before they become adult Boxers.

12-Month-Old Boxer Dog (Fully Grown)

By the time your male Boxer dog is fully developed at 12 months old, it should weigh around 60 to 70 pounds, while a female Boxer dog weighs between 55 and 65 pounds. 

At 12 months, your Boxer is considered a full-grown Boxer, although some Boxers continue to grow until they are 18 months old. At this age, they should be able to develop properly and form a sturdy, muscular body.

Your Boxer should be able to do complex commands, have great stamina, and have healthy muscles.

When socializing your 1-year-old Boxer, be cautious because they might trample smaller breeds with their size. Ultimately, the food they intake greatly impacts the intensity of their growth.

Before you consider buying a Boxer puppy, it’s best to know how much it costs so you can carefully adjust your budget according to their needs.

Frequently Asked Questions

How Big Should a 6-Month-Old Boxer Dog Be?

The ideal weight for a 6-month-old male Boxer is around 41 to 48 pounds, while a female Boxer weighs between 39 and 44 pounds. Males are approximately 17 to 19 inches tall, while females are 16 to 18 inches tall.

How Does Neutering/Spaying Affect My Boxer’s Growth?

Spaying or neutering your Boxer dog may cause them to gain weight because this procedure slows down its metabolism. You might observe that your furry friend may get bulkier after being spayed or neutered.

The weight gain isn’t a cause for alarm, but it may be a good sign to switch up your Boxer’s exercise and diet plans. Spaying and neutering may affect their joints, especially since they are medium to large-sized dogs. 

Veterinarians urge dog owners to have their dogs spayed or neutered when they reach the right weight and their bones are fully developed. In most cases, it is at two years old when they reach their ideal adult weight.

What Weight Is Overweight for a Boxer?

A fully grown Boxer dog reaches its adult weight of 60 to 70 pounds for males and 55 to 65 pounds for females. If your Boxer weighs 10 pounds or more than the average, it is most likely overweight.

Helping your Boxer dog lose weight before it reaches obesity is something that needs to be considered.

It’s best to revisit the Boxer growth chart to assess how much weight they need to lose in order to maintain their standard adult size according to their age.

Your dog’s diet plays an important role in maintaining its ideal weight so that it won’t have to suffer the side effects of being overweight. Avoid giving too many treats as well that may add to their total caloric intake.

What Size Crate Does a Boxer Need?

Before you get a crate for your Boxer, it’s important to look at the average size of the Boxer breed. Like most dog breeds, male Boxers are larger than females.

Male Boxers grow 23 to 25 inches tall, and females grow between 21.5 and 23.5 inches. Look for a crate that is able to accommodate a large dog breed to ensure comfort and safety.

Crates that are at least 42 inches long, 28 inches wide, and 30 inches high can give enough space for your Boxer to toss around without bumping into the crate. Make sure there is enough space for them to lay comfortably too.

Final Thoughts

Monitoring a Boxer’s weight as it grows is undeniably tricky, but with the help of this Boxer growth chart, pet owners will surely find it easier to observe and adapt according to their Boxer’s growth stages.

When monitored properly, Boxer puppies grow strong, fit, and healthy. The right amount of food, exercise, rest, and play go hand in hand when taking care of a Boxer dog. 

To rely on the Boxer growth chart is good, but to get the best and most accurate results, you should consult a veterinarian about your pet’s ideal weight and height. Vets can give you information about how their lives can improve.
