Miniature Boxer Dog Breed

White & Black Miniature Boxer
  • Other names:
  • Mini Boxer
  • Boxer / Boston Terrier

Pronunciation: [mi-nee—ah chur box-ur]

Contrary to the name, a Miniature Boxer is not a purebred but produced by crossbreeding a Boxer and a Boston Terrier. This recently conceived crossbreed is becoming somewhat popular. Miniature Boxers not only look a lot like purebred Boxers but tend to have a lot of the Boxer's temperament and other characteristics. Boston Terriers are preferred for producing Mini-Boxers because Terriers tend to not influence the genetic inheritance save for the smaller size. If you want to adopt a Miniature Boxer, you would do very well to learn as much as you can about the Boxer so that you will be prepared for this extremely energetic, greatly devoted and wonderfully task-driven dog. (Be sure to know a bit about the Boston Terrier too, of course!)

The purebred parents of the Miniature Boxer come from two different groups. The American Kennel Club (AKC) puts the Boxer in the Working Group and the Boston Terrier in the Non-Sporting Group. The Boxer, however, tends to be genetically dominant in this hybrid dog. They can perform keen watchdog duties but only light guard duties, are great at protecting the kids, and love being a companion to people in need of one. These qualities make this versatile mixed breed a great dog for first-time families and solitary persons alike.

Miniature Boxer Breed Description

Miniature Boxers are not purebred Boxers, but they tend to basically be smaller versions of Boxers. The Boxer's temperament almost always prevails because Boston Terriers are a breed that usually allows the other parent breed to dominate genetically save for the down-sizing aspect. This Miniature Boxer information can be supplemented by visiting both parent breed pages.

The intelligence of the Miniature Boxer is both boon and bane: if handled well — early, consistent and proper training — then this hybrid's intelligence will be a boon. Failing to manage this hybrid dog's desire to learn, explore and chase will definitely result in things being chewed, items being destroyed and a growing aggression toward people, other pets and most other animals. Be sure to be responsible for your Miniature Boxer and her intelligence will reward both of you!

Miniature Boxers are great dogs because they can be trained with moderate effort and gets along well with kids. This mixed breed is playful, energetic and loyal, but they are also great watch dogs; if a dire threat emerges, they will often do what they can to be all the guard dog they can be. They love to be alongside their loved ones as much as possible too.

Although they are good hybrid dogs for first-time families and solitary people, they do require a great amount of exercise. While small in size, Miniature Boxers love to run and play almost endlessly, and their strength and stamina will surprise you.

Miniature Boxer Coloring

Miniature Boxer hybrids are produced from crossbreeding Boxers and Boston Terriers. (They should not be confused with Dwarf Boxers, as these are purebreds with a gene problem that results in abnormal bone growth.) The coat colors are few, as both Boxers and Boston Terriers have but a handful of colors between them that are recognized by the American Kennel Club (AKC). Boxers have a base coat of fawn and can have a pattern of brindle whereas Boston Terriers have five colors considered standard. Finally, many backyard breeders (BYBs) will claim to have "rare" colors of Boston Terriers, but this "comeback" of coat colors is highly controversial as the AKC ruled them out in 1900.

The colors that a Miniature Boxer hybrid may be are:
Any combination of the above colors
(They usually have lighter or white markings on the chest.)

Miniature Boxer Size

Fully grown Mini Boxers tend to be about 15 to 22 inches in height and weigh from 20 to 55 pounds. Those that are properly crossbred, so to speak, are Boxers crossed with a Boston Terrier so as to retain the Boxer look albeit in a smaller size.

Of course, Miniature Boxer size may be much smaller if the breeder has been working on multiple generations of cross-breeding, but as this hybrid has reportedly been around only since about 2010, that is highly unlikely. There are also Dwarf Boxers that have a genetic defect which results in malformed bones, so if the Boxer parent is already very small, you should certainly look into this.

Average Adult Height

15-22 in
*Height is measured in inches from the front paws to the top of the shoulder while the dog is standing on all four legs.

Average Adult Weight

Miniature Boxer Temperament

The Miniature Boxer is produced from two very disparate parent breeds: the Boxer and the Boston Terrier. Just as the Boxer's physical characteristics will almost certainly dominate the puppies produced when crossed with a Boston Terrier, so too should the temperament tend to dominate. (Unfortunately, this mixed breed has been around since only about 2010, there is very little else definitively known about the temperament of the Boxer / Boston Terrier mix.) Purebred Boxers are highly intelligent, rather headstrong and extremely protective of their loved ones. They usually give chase to small animals, can be overly protective of their loved ones and are rather highly active; these potential personality issues can be mitigated with early training, wide socialization (at home, on walks and in parks) and a lot of exercise.

While the basic Miniature Boxer temperament is generally alright for first-time families, failing to be responsible for your puppy can result in shyness around strangers, dominating the household and destructive behavior. They do play well with kids, however, and are great watchdogs as well as are extremely devoted. It's best to learn a lot about purebred Boxers as well as spend at least some time researching Boston Terriers so you can best understand the possible temperament of your Miniature Boxer. It's even better to meet the parents; doing so will help you to understand the possible temperament that your Mini-Boxer hybrid dog may inherit.

Miniature Boxer Health

The Miniature Boxer is one of those hybrids that tends to not mitigate the many health concerns that the two parent breeds bring to the figurative table. This crossbreed has been around only since about 2010, so the doctor is still out, so to speak, on a firm diagnosis. There are many personal reports that allege serious ailments regarding the heart, thyroid and joint problems — among a host of other issues. The biggest concern, however, is cancer, and that requires a lot of responsibility should this develop in your companion.

Visit the parent breed pages (Boxer and Boston Terrier) for a list of common health issues-- some of which can potentially be passed down to your Mini. Kept healthy, happy and well-exercised, you should expect your Miniature Boxer to live from 12 to 15 years.
