The Boxer is a medium to large, short haired dog breed of mastiff type, developed in Germany. The coat is smooth and tight fitting; colors are fawn, brindled, or white, with or without white markings. Boxers are brachycephalic (they have broad, short skulls), have a square muzzle, mandibular prognathism (an underbite), very strong jaws, and a powerful bite ideal for hanging on to large prey. The Boxer was bred from the Old English Bulldog and the now extinct Bullenbeisser, which became extinct by crossbreeding rather than by a decadence of the breed. The Boxer is a member of both The Kennel Club and American Kennel Club (AKC) Working Group. The first Boxer club was founded in 1895, with Boxers being first exhibited in a dog show for St. Bernards in Munich the next year. Based on 2013 AKC statistics, Boxers held steady as the seventh most popular breed of dog in the United States for the fourth consecutive year. According to the AKC's website, though, the boxer is now the 11th most popular dog breed in the United States.

The head is the most distinctive feature of the Boxer. The breed standard dictates that it must be in perfect proportion to the body and above all it must never be too light. The greatest value is to be placed on the muzzle being of correct form and in absolute proportion to the skull. The length of the muzzle to the whole of the head should be a ratio of 1:3. Folds are always present from the root of the nose running downwards on both sides of the muzzle, and the tip of the nose should lie somewhat higher than the root of the muzzle. In addition, a Boxer should be slightly prognathous, i. e., the lower jaw should protrude beyond the upper jaw and bend slightly upwards in what is commonly called an underbite or "undershot bite". Boxers were originally a docked and cropped breed, and this is still done in some countries, but due to pressure from veterinary associations, animal rights groups, and the general public, both cropping of the ears and docking of the tail have been prohibited in many countries around the world, and is not recognised by the breed standard laid down by The Kennel Club of the UK. The American Kennel club still permits cropped ears. A line of naturally short tailed (bobtail) Boxers was developed in the United Kingdom in anticipation of a tail docking ban there; after several generations of controlled breeding, these dogs were accepted in the Kennel Club (UK) registry in 1998, and today representatives of the bobtail line can be found in many countries. In 2008, the Fédération Cynologique Internationale (FCI) added a "naturally stumpy tail" as a disqualifying fault in their breed standard, meaning those Boxers born with a bobtail can no longer be shown in FCI member countries. In the United States and Canada as of 2012, cropped ears are still more common in show dogs, though the practice of cosmetic cropping is currently opposed by the American Veterinary Medical Association. In March 2005, the AKC breed standard was changed to include a description of the uncropped ear, but to severely penalize an undocked tail. The tail of a boxer is typically docked before the cartilage is fully formed, from 3–5 days old. The procedure does not require any sutures when performed at this young age, and anesthesia is not used. The docking of the tail is not permitted under the breed standard of The Kennel Club UK.

The Boxer is a short haired breed, with a smooth coat that lies tight to the body. The recognized colors are fawn and brindle, called "flash", often extend onto the neck or face, and dogs that have these markings are known as "flashy". "Fawn" denotes a range of colors, the tones of which may be described variously as light tan or yellow, reddish tan, mahogany, or stag/deer red, and dark honey blonde. In the UK and Europe, fawn Boxers are typically rich in color and are often called "red". "Brindle" refers to a dog with black stripes on a fawn background. Some brindle Boxers are so heavily striped that they give the appearance of "reverse brindling", fawn stripes on a black body; these dogs are conventionally called "reverse brindles", but that is actually a misnomer—they are still fawn dogs with black stripes. In addition, the breed standards state that the fawn background must clearly contrast with or show through the brindling. The Boxer does not carry the gene for a solid black coat color, so purebred black Boxers do not exist. Boxers that appear black are actually heavily brindled, where the fawn color is completely sealed out by the black striping. These are often referred to as "sealed" Boxers, and are not an AKC recognized coloring.

The Boxer is a hunting mastiff developed in Germany in the late 19th century from the now extinct Bullenbeisser, a dog of English Mastiff descent, and Bulldogs brought in from Great Britain. In 1894, three Germans, Friedrich Robert, Elard König, and R. Höpner, decided to stabilize the breed and put it on exhibition at a dog show. This was done in Munich in 1896, and the year before they founded the first Boxer Club, the Deutscher Boxer Club. The club went on to publish the first Boxer breed standard in 1904, a detailed document that has not been changed much since. The breed was introduced to other parts of Europe in the late 19th century and to the United States around the turn of the 20th century. The AKC registered the first Boxer in 1904,]] Commented out until copyright issue over this image is resolved. If cleared of possible copyvio violations, can be uncommented. >

German citizen George Alt, a Munich resident, mated a brindle colored female dog imported from France named Flora with a local dog of unknown ancestry, known simply as "Boxer", resulting in a fawn and white male, named Lechner's Box after its owner. This dog was mated with his own dam, Flora, and one of his offspring was a female called Alt's Schecken. George Alt mated Schecken with a Bulldog named Dr. Toneissen's Tom to produce the historically significant dog Mühlbauer's Flocki. Flocki was the first Boxer to enter the German Stud Book after winning the aforementioned show for St. Bernards in Munich 1896, which was the first event to have a class specific for Boxers. John Wagner, in The Boxer (first published in 1939) said the following regarding this female dog:

Meta von der Passage played the most important role of the five original ancestors. Our great line of sires all trace directly back to this female. She was a substantially built, low to the ground, brindle and white particolor, lacking in underjaw and exceedingly lippy. As a producing female, few in any breed can match her record. She consistently whelped puppies of marvelous type and rare quality. Those of her offspring sired by Flock St. Salvator and Wotan dominate all present day pedigrees. Combined with Wotan and Mirzl children, they made the Boxer.

A 2024 UK study found a life expectancy of 11.3 years for the breed compared to an average of 12.7 for purebreeds and 12 for crossbreeds. Leading health issues to which Boxers are prone include cancers, heart conditions such as aortic stenosis and arrhythmogenic right ventricular cardiomyopathy (the so called "Boxer cardiomyopathy"), hypothyroidism, hip dysplasia, and degenerative myelopathy and epilepsy; other conditions that may be seen are gastric dilatation volvulus (also known as bloat), intestinal problems, and allergies (although these may be more related to diet than breed). Entropion, a malformation of the eyelid requiring surgical correction, is occasionally seen, and some lines have a tendency toward spondylosis deformans, a fusing of the spine, or dystocia. Other conditions that are less common but occur more often in Boxers than other breeds are histiocytic ulcerative colitis (sometimes called Boxer colitis), an invasive E. coli infection, and indolent corneal ulcers, often called Boxer eye ulcers. An emerging health concern among boxers is Boxer Juvenile Kidney Disease (JKD), where the kidneys do not develop normally during gestation and leads to chronic renal failure. JKD is most frequently diagnosed in dogs under the age of 3, and often much earlier than this in puppies before the age of 12 months. There is strong evidence to suggest JKD is an inherited condition in boxers with research being undertaken by the University of Ohio to determine the gene mutation, as well as other work separately by the UK Boxer Breeder Council. About 22% of puppies die before reaching seven weeks of age. Stillbirth is the most frequent cause of death, followed by infection. Mortality due to infection increases significantly with increases in inbreeding. Median lifespan was 10.25 years. Responsible breeders use available tests to screen their breeding stock before breeding, and in some cases throughout the life of the dog, in an attempt to minimize the occurrence of these diseases in future generations. As an athletic breed, proper exercise and conditioning is important for the continued health and longevity of the Boxer. While on a high calorie diet, owners should be thoughtful of the amount of treats given as this tends to cause obesity. Plaque can also be removed by crude fiber in kibble, which has a flexible structure that increases chewing time. Dry dog food is often coated with polyphosphates, which further reduces plaque buildup by preventing calcium production in saliva.
