Mini Boxer

The Miniature Boxer — also known as the Boston Boxer — is, as the name would suggest, a cross between the Boston Terrier and a Boxer. They’re generally a friendly and playful breed, and as long as they’re socialized, tend to get along well with all people — including children and other animals.

In this guide to the Miniature Boxer, you’ll discover:

  • The Miniature Boxer dog is a cross between a Boston Terrier and a Boxer
  • Appearance can vary, but typically these dogs look like a miniature version of a  boxer. 
  • Both parent breeds are high-energy, so these dogs need plenty of exercise. 
  • This crossbreed is fairly intelligent and easy to train — but can be stubborn. 


Miniature Boxer breed overview

This crossbreed tends to be most like the Boxer but can and does, of course, often get elements of their appearance and personality from the Boston Terrier, too. 

If you’re considering getting a puppy from a reputable breeder then you should expect to pay between $700 and $2000. The puppies that look the most like the Boxer often cost more than those that look more like the Boston Terrier. If you rescue a Mini Boxer then it’ll be much cheaper — around $150 to $500. 

You should be aware that some breeders are crossing other breeds such as the Pug and Fox Terrier or the Pug and Rat Terrier and calling them a Miniature Boxer when they don’t actually have Boxer in them at all. 

The Miniature Boxer lifespan is between 12 and 15 years, which is longer than the Boxer’s 10 to 12 years — smaller breeds generally live longer than larger types, good health permitting.



The last thing you want to think about is your Miniature Boxer having any health issues. But, it’s quick and easy to compare the best pet insurance plans from top providers and you’ll have peace of mind that they are covered should anything happen.

Miniature Boxer Breed History

The Miniature Boxer is thought to be a fairly new crossbreed — although some believe they  may have been being bred for much longer. They’ve become particularly popular in North America, but aren’t recognized by the American Kennel Club. 

The Boston Terrier, the state dog of Massachusetts, originated — unsurprisingly — in Boston. In the late 1800s ‘Judge’, a mix of an English Bulldog and white English terrier, was bred with a white female and these pups were the beginning of the Boston Terrier breed. It’s believed the French Bulldog was later used to reduce the size of the Boston Terrier. 

The Boston Terrier was recognized by the American Kennel Club in 1893. From 1905 to 1939 they were the most popular breed in America and they still maintain their popularity today.

The Boxer originated in Germany in the 19th and early 20th centuries and may have been a distant relative of the English Bulldog. Initially they were used for working, guarding and hunting.

Later, during both World Wars, the Boxer breed was utilized as messengers and carriers of supplies and ammunition. Soldiers returning from those wars brought these dogs back to the United States with them and their popularity soared. 

The American Kennel Club first recognized the Boxer breed in 1904.

Miniature Boxer Breed Appearance

If you were to look at a Miniature Boxer vs a Boxer, you’d see why the Boston Boxer is also known as the Miniature Boxer. While they may be a mix of both breeds a Mini Boxer is exactly what this crossbreed often looks like. Of course, they can take on the appearance and characteristics of one or both of the parent breeds. 

A full grown Miniature Boxer can weigh anywhere from 25 to 55 pounds and stand between 15 and 22 inches tall. They can have a small and compact body, or it may be more muscular and medium-sized. The head is broad, with a square face and blunt muzzle. They often have brown eyes (which may be protruding) and a black nose. 

Ears can be small and erect or long and floppy. The Mini Boxer’s coat is likely to be short, fine, and smooth. The colors tend to be brindle, fawn or black with white markings.

Miniature Boxer Breed Maintenance

Both breeds that form the Miniature Boxer shed a fairly minimal amount. This crossbreed will require regular brushing though. Use a firm bristle brush to remove loose hair and debris. They’ll only need a bath if they’ve rolled in something smelly. 

You should check their ears regularly and clean them out when necessary. Likewise, you’ll need to trim their nails when needed too. Brushing their teeth should be done as least two to three times a week, if not daily. 

Both parent breeds are high energy types and therefore your Mini Boxer needs plenty of exercise, including long daily walks — especially during their first six years. This crossbreed is known to wander so you may want to keep them on a leash. But, they do like to run, so fenced backyards or dog parks are a great way to allow them to stretch their legs. 

Be aware, this crossbreed has a low tolerance to heat and is prone to heat stroke - so you’ll have to be particularly careful exercising them on hot days. You should also be careful on very cold days, too. 

They can live in apartments, but it’s even more important to make sure they’re getting regular exercise.


Miniature Boxer health risks 

Miniature Boxers are prone to a number of health conditions. The ones you need to be particularly aware of, include: 

  • Degenerative Myelopathy 
  • Brachycephalic Syndrome 
  • Subaortic Stenosis 
  • Dilated Cardiomyopathy (DCM)

There’s also a chance of a Mini Boxer developing the following, although these are only relatively minor concerns: 

As there are a number of health conditions your Miniature Boxer can get, it’s important to have a good insurance policy. Browse and compare top pet insurance providers to find the best option for you and your dog. 

Degenerative Myelopathy 

Degenerative myelopathy is a type of spine degeneration. Symptoms of this type include inability to climb stairs or get into a vehicle, loss of balance and coordination as well as hind leg muscle loss. It’s a slow and painless deterioration of the spine. But, sadly, there is no cure — it’s important to visit your vet to ensure your dog has the best quality of life as it progresses. 

Brachycephalic Syndrome 

Brachycephalic syndrome is typical in brachycephalic breeds, which includes Boxers and Boston Terriers. It’s caused by deformities in the upper airways and can cause breathing difficulties and overheating. Symptoms include loud breathing, difficulty eating and difficulty coping with exercise. Surgery may be required. 

Subaortic Stenosis 

Subaortic stenosis is when the outlet underneath the aortic valve in the heart narrows. This means the heart has to work harder and, as a result, strain is put on the cardiovascular system. This is typical in Boxers and symptoms can include fainting, appearing weak and lethargy. It may be treated with medications but in some instances surgery could be required. 

Dilated Cardiomyopathy (DCM)

Dilated cardiomyopathy — or enlarged heart — is common in Boxers, particularly middle-aged males. It occurs when the heart muscle becomes thinner and is weakened. The symptoms vary but can include getting tired easily, struggling to exercise, regularly coughing or clearing their throat and panting excessively. There’s no cure but seeing your vet as soon as possible can help to slow the progression.



Feeding a Miniature Boxer — what’s the best diet?

Your Miniature Boxer will benefit from high-quality dry food that’s suitable for a medium sized dog, and relevant to their age. 

This breed has a healthy appetite but while you want to make sure you’re feeding them enough for their activity level, you don’t want to overfeed them. They can quickly become overweight. So, keep this in mind when it comes to giving them treats too. 

Miniature Boxer puppies should be fed three to four times a day, while adults can be fed just once or twice a day. 

Do you think you’re feeding your Miniature Boxer the best possible diet that’s both tasty and beneficial to their health? Take a look at the advice from our friends at Dog Food Advisor such as the best dog food for Boxers and the best dog food for Boston Terriers.

Miniature Boxer Temperament

Much like their appearance, the temperament of the Miniature Boxer can come from one of both of the parent breeds. This crossbreed is friendly, loving, gentle and affectionate — making them a perfect family pet. 

Social, playful and friendly, the Miniature Boxer loves people, children and other animals, including cats. You will need to make sure you socialize them, though. This breed is quite intelligent and easy to train but can be strong-willed so need to know who is in charge! 

While the Mini Boxer can be left alone, it shouldn’t be for long periods of time. They do, however, make an effective watchdog — alert as well as loyal and protective, which means they look out for their family and are likely to bark at strangers in the house. They can occasionally show signs of aggression in this situation so new introductions should be done slowly.
