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.http://www.akc.org/dog-breeds/boxer/#standard "Get to Know the Boxer", 'The American Kennel Club', Retrieved 14 May 2014

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,http://www.akc.org/dog-breeds/boxer/ though, the boxer is now the 11th-most popular dog breed in the United States.

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 it must never be too light. The greatest value is placed on the muzzle in 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. 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 recognized by the breed standard determined 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. As of 2012, cropped ears are still more common in show dogs in Canada and the United States, 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,Sheila Schmutz: Boxer 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.

White Boxers Boxers with white markings covering more than one-third of their coat – conventionally called "white" Boxers – are neither albino nor rare; about 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 darker Boxers. The extreme piebald gene, which is responsible for white markings in Boxers, is linked to congenital sensorineural deafness in dogs. An estimated 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. A 1998 study of Boxers in the Netherlands showed that 17% of Boxer pups were euthanized because they were white. Previously, the American Boxer Club "unofficially recommended euthanasia for these animals." Reasons for euthanizing white pups include the view that selling a dog with "faults" is unethical, which is in stark contrast to the AKC preference for docked tails. Additionally there is the perception that white Boxers are at higher risk of ending up abandoned in rescues. Today, breeders are increasingly reluctant to euthanize healthy pups and may choose to neuter and place them in pet homes, instead.

Temperament

Boxers are a bright, energetic, and playful breed and tend to be very good with children. They are patient and spirited with children, but also protective, making them a popular choice for families. They are active, strong dogs that 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, an approach based on operant conditioning and behaviorism, which offers the dog an opportunity to think independently and problem-solve. In a survey of obedience trainers by Stanley Coren, summarized in his book The Intelligence of Dogs, Boxers were ranked at number 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 is not an aggressive or vicious breed. It is a guardian and can become very attached to its family. Like all dogs, it requires proper 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. Their patient, easy-going nature allows them to become great family dogs and do well around young children.

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, 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 breed was introduced to a wider audience and soon became a favorite as a companion, show dog, and guard dog.

Early genealogy

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 in 1896, which was the first event to have a class specific to Boxers.

The white female dog, 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 (particolored) female dog Meta von der Passage, which, even bearing little resemblance with the modern Boxer standard (early photographs depict 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 female dog:

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."
