Overview: A Few Fun Facts About the Boxer

If you’re thinking of bringing home a Boxer, then you’ll be happy to know these dogs are friendly and gentle.

A good place to start looking into your Boxer’s growth is the American Kennel Club (AKC). According to their breed standard for Boxers, your male doggo will grow to be about 23 to 25 inches (58.4 to 63.5 cm) tall and weigh between 60 and 70 pounds (27.2 to 31.7 kg).

If you have a female Boxer, they may grow to be 21.5 to 23.5 inches (54.6 to 59.6 cm) tall and weigh 55 to 65 pounds (24.9 to 29.4 kg).

There are a few ways for you to estimate whether or not your Boxer is still growing. One way is your dog’s age. Most Boxer pups continue to grow until they are between 18 and 24 months old.

Another way is to look at your pup’s paws. If your Boxer’s paws are still fairly big and don’t seem proportionate to their body yet, then chances are they’re still growing. Dogs will grow into their paws over time.

Finally, if you got your pooch from a breeder, then you can contact them. The breeder should give you an estimated time frame based on the puppy’s parents’ growth. Of course, if you didn’t get it from a breeder, you could always do a DNA test.

How much should an average Boxer weigh?

When a Boxer puppy is born, it should weigh between 2.5 and 3.2 pounds (1.2 to 1.4 kg).

As an adult, your male Boxer dog should weigh between 60 and 70 pounds (27.2 to 31.7 kg). Female Boxers should weigh between 55 and 65 pounds (24.9 to 29.4 kg).

Things You Should Know About Your Boxer’s growth

Your dog’s growth is more than your pooch getting taller and gaining weight. Many factors are involved. For your doggo to maintain a healthy lifestyle, monitoring their growth and weight is a good idea. 

How can you tell how big a Boxer will get?

Within the first six months of age, your Boxer will grow rapidly. You can tell how big your pooch may get by looking at their paws and head.

For example, your furry friend may look disproportionate for a while. However, some parts of their body will catch up to the rest within a few months or even a few weeks.

Is your Boxer at a healthy weight?

You can typically tell whether or not your Boxer is at a healthy weight by their ribs.

For instance, if you can’t feel their ribs, they may be overweight. But, on the other hand, if you can feel and see their ribs, they may be underweight.

Always check with your vet to be on the safe side.

What are some Boxer dog body shape changes?

Boxer puppies grow in height faster than their weight gain. So, if your pooch looks a little round, that’s normal. When this dog breed matures and becomes an adult, they will have a wide chest. But, overall, Boxer is strong and lean.

Factors that Can Impact How Big Your Boxer Dog Will Be and How Fast They Will Grow

Every dog is different, so your pup’s growth may slightly differ from another Boxer’s growth. In addition, different factors are involved when it comes to impacting how your dog grows. So, let’s talk about a few of them.


Genetics plays a huge role in your Boxer dog’s growth. As a dog owner, you should ask for the information of your puppy’s parents and grandparents. In addition, reputable breeders should have this information.

Based on how the parents and grandparents grew, you’ll have an estimated idea of how big and tall your pup will get.


Your Boxer’s diet plays another important role in your dog’s growth. The nutrition you feed your pooch can help or hinder their growth.

For example, if you feed them dog food with unhealthy fillers and lots of fat, they may become obese, thus hurting their growth and overall health.

Will neutering or spaying your Boxer affect their growth?

Spaying or neutering your Boxer has more pros than cons. It prevents unwanted pregnancy, keeps unwanted behavior at may causing your pooch to mature a bit faster, and it’s good for their overall health and well-being.

While this process does not affect your Boxer’s growth in any way, it could affect their growth plates in their joints. So, it’s recommended to spay or neuter your Boxer when they are two years old.

Health issues that can influence a Boxer puppy’s growth

Unfortunately, Boxers may have some health problems that can affect them.

For example, some health conditions may include hip dyslexia, bloat, acne, arthritis, and cancer.

The best way to ensure your pooch remains healthy is to work together with your veterinarian. Take your dog to regular vet appointments at least once per year for an annual check-up.

In addition, talk to your vet about the type of dog food and exercise your Boxer should be getting. If your doggo is overweight or underweight, the vet will be able to help.

Finally, properly groom your doggo. Keeping your Boxer’s coat, skin, and teeth clean will keep them in good shape.

Physical activity

Boxers need plenty of room to run around and stretch their legs. However, they love to play and enjoy a round of fetch with you in a fenced-in yard.

They wouldn’t mind a good walk or jog, either. Just be sure to wait until their bones and joints are fully developed before taking them for jogs or hikes. Otherwise, they could have joint issues later in life.

Dangers of stunted or accelerated growth

If your Boxer is a little bigger or small than the others of its breed, that may not necessarily be a bad thing. However, some issues can occur.

For example, your pooch may be smaller due to a growth hormone deficiency. This controls the growth rate in dogs, their bone and teeth development and maintains a healthy coat.

This deficiency could mean the pituitary gland didn’t develop properly, there’s an infection in the pituitary gland, cysts are on the gland, or there’s a tumor.

Dwarfism could also be the reason. This affects the dog’s size and proportion. In other words, their bones don’t grow to the expected size. However, this isn’t as common in Boxers as in other breeds, such as Beagles.

When do Boxers stop growing?

Since Boxers are medium to large breed, they’ll take a little longer to grow than small dog breeds. You can expect your Boxer to be fully grown and stop growing between 18 and 24 months of age.
