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

Coat and colors

, often 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 color, 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, so a dog that is too heavily brindled may be disqualified by the breed standard.

White Boxers

Boxers with white markings covering more than one-third of their coat – conventionally called "white" Boxers – are neither albino nor rare; approximately 20–25% of all Boxers born are white. Genetically, these dogs are either fawn or brindle, with excessive white markings overlying the base coat color. Like fair-skinned humans, white Boxers have a higher risk of sunburn and associated skin cancers than colored Boxers. The extreme piebald gene, which is responsible for white markings in Boxers, is linked to congenital sensorineural deafness in dogs. It is estimated that about 18% of white Boxers are deaf in one or both ears, though Boxer rescue organizations see about double that number. In the past, breeders often euthanized

 white puppies at birth; today, most breeders place white puppies in pet homes with spay/neuter agreements. White Boxers are disqualified from conformation showing by the breed standard, although in 2010, the German Boxer Club opened up an exhibition-only conformation class for white Boxers. They are prohibited from breeding by every national Boxer club in the world, but can compete in non-conformation events such as obedience and agility, and like their colored counterparts do quite well as service and therapy dogs.

Temperament

Boxers are a bright, energetic and playful breed and tend to be very good with children. They are active, strong dogs and require adequate exercise to prevent boredom-associated behaviors such as chewing, digging, or licking. Boxers have earned a slight reputation of being "headstrong," which can be related to inappropriate obedience training. Owing to their intelligence and working breed characteristics, training based on corrections often has limited usefulness. Boxers, like other animals, typically respond better to positive reinforcement techniques such as clicker training

, ranked Boxers at #48 – average working/obedience intelligence. Many who have worked with Boxers disagree quite strongly with Coren's survey results, and maintain that a skilled trainer who uses reward-based methods will find Boxers have far above-average intelligence and working ability.

The Boxer by nature is not an aggressive or vicious breed but, when provoked, is a formidable guardian of any family or home and, like all dogs, requires socialization. Boxers are generally patient with smaller dogs and puppies, but difficulties with larger adult dogs, especially those of the same sex, may occur. Boxers are generally more comfortable with companionship, in either human or canine form.

Early genealogy

The German citizen George Alt, a Munich resident, mated a brindle-colored bitch 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 its offspring was a bitch 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. Bernard

s in Munich 1895, which was the first event to have a class specific for Boxers.

The white bitch Ch. Blanka von Angertor, Flocki's sister, was even more influential when mated with Piccolo von Angertor (Lechner's Box grandson) to produce the predominantly white (parti-colored) bitch Meta von der Passage, which, even bearing little resemblance with the modern Boxer standard (early photographs depicts her as too long, weak-backed and down-faced), is considered the mother of the breed. John Wagner, in The Boxer (first published in 1939) said the following regarding this bitch:

Breed name

The name "Boxer" is supposedly derived from the breed's tendency to play by standing on its hind legs and "boxing

" with its front paws. According to Andrew H. Brace's Pet owner's guide to the Boxer, this theory is the least plausible explanation. He claims "it's unlikely that a nation so permeated with nationalism would give to one of its most famous breeds a name so obviously anglicised".
German linguistic and historical evidence find the earliest written source for the word Boxer in the 18th century, where it is found in a text in the Deutsches Fremdwörterbuch (The German Dictionary of Foreign Words), which cites an author named Musäus of 1782 writing "daß er aus Furcht vor dem großen Baxer Salmonet ... sich auf einige Tage in ein geräumiges Packfaß ... absentiret hatte". At that time the spelling "baxer" equalled "boxer". Both the verb (boxen [English "to box, to punch, to jab"]) and the noun (Boxer) were common German words as early as the late 18th century. The term Boxl, also written Buxn or Buchsen in the Bavarian dialect, means "short (leather) trousers" or "underwear". The very similar-sounding term Boxerl, also from the Bavarian dialect, is an endearing term for Boxer. More in line with historical facts, Brace states that there exist many other theories to explain the origin of the breed name, from which he favors the one claiming the smaller Bullenbeisser

 of that word.

In the same vein runs a theory based on the fact that there were a group of dogs known as Bierboxer in Munich by the time of the breed's development. These dogs were the result from mixes of Bullenbeisser and other similar breeds. Bier (beer) probably refers to the Biergarten, the typical Munich beergarden, an open-air restaurant where people used to take their dogs along. The nickname "Deutscher Boxer" was derived from bierboxer and Boxer could also be a corruption of the former or a contraction of the latter.

A passage from the book "The Complete Boxer" by Milo G Denlinger states:

, which is evidence that "Boxer" was commonly used as a dog name by the early 19th century, before the establishment of the breed by the end of that same century.

The name of the breed could also be simply due to the names of the very first known specimens of the breed (Lechner's Box, for instance).

. Other conditions that are less common but occur more often in Boxers than other breeds are hystiocytic ulcerative colitis (sometimes called Boxer colitis), an invasive E. coli infection, and indolent corneal ulcers, often called Boxer eye ulcers.

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. Average age of death was 9 years and 8 months. 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. Care must be taken not to over-exercise young dogs, as this may damage growing bones; however once mature Boxers can be excellent jogging or running companions. Because of their brachycephalic head, they do not do well with high heat or humidity, and common sense should prevail when exercising a Boxer in these conditions.
