Dog breed · German Empire
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 or brindled, 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.
Temperament: The character of the Boxer is of the greatest importance and demands the most solicitous attention. He is renowned from olden times for his great love and faithfulness to his master and household. He is harmless in the family, but can be distrustful of strangers, bright and friendly of temperament at play, but brave and determined when aroused. His intelligence and willing tractability, his modesty and cleanliness make him a highly desirable family dog and cheerful companion. He is the soul of honesty and loyalty, and is never false or treacherous even in his old age.

Characteristics
Appearance: 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 some 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.
Coat And Colors: The Boxer is a short-haired breed, with a smooth coat that lies tight to the body. The recognized colors are fawn and brindle, frequently with a white underbelly and white on the feet. These white markings, 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.
Health: 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. A 2024 Italian study found a life expectancy of 9 years for the breed compared to 10 years overall. A 2005 Swedish study of insurance data found 50% of Boxers died by the age of 10, higher than the overall rate of 35% of dogs dying by the age of 10.
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.
According to a UK Kennel Club health survey, cancer accounts for 38.5% of Boxer deaths, followed by old age (21.5%), cardiac (6.9%) and gastrointestinal (6.9%) related issues. The breed is particularly predisposed to mast cell tumours, a cancer of the immune system. 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.
History: 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. The Bullenbeisser had been working as a hunting dog for centuries, employed in the pursuit of bear, wild boar, and deer. Its task was to seize the prey and hold it until the hunters arrived. In later years, faster dogs were favored and a smaller Bullenbeisser was bred in Brabant, in northern Belgium. The Brabanter Bullenbeisser is generally accepted as being a direct ancestor of today's Boxer.
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, and recognized the first Boxer champion, Dampf vom Dom, in 1915. During World War I, the Boxer was co-opted for military work, acting as a valuable messenger dog, pack carrier, attack dog, and guard dog. The Boxer did not become popular around the world until after World War II. Taken home by returning soldiers, the dog was introduced to a wider audience and soon became a favorite as a companion, a show dog, and a guard dog.
