A dog breed is a particular type of dog that was purposefully bred by humans to perform specific tasks, such as herding, hunting, and guarding. Dogs are the most variable mammal on Earth, with artificial selection producing upward of 360 globally recognized breeds. These breeds possess distinct traits related to morphology, which include body size and shape, tail phenotype, fur type, etc, but are only one species of dog. Their behavioral traits include guarding, herding, and hunting, and personality traits such as hyper-social behavior, boldness, and aggression. Most breeds were derived from small numbers of founders within the last 200 years. As a result of their adaptability to many environments and breedability for human needs, today dogs are the most abundant carnivore species and are dispersed around the world.
The American Kennel Club (AKC) is a registry of purebred dog pedigrees in the United States. In addition to maintaining its pedigree registry, this kennel club also promotes and sanctions events for purebred dogs, including the Westminster Kennel Club Dog Show, an annual event which predates the official forming of the AKC, the National Dog Show and the AKC National Championship. The AKC is a non-member partner with the Fédération Cynologique Internationale. The AKC recognizes 200 dog breeds, as of 2022.
A coonhound, colloquially a coon dog, is a type of scenthound, a member of the hound group. They are an American type of hunting dog developed for the hunting of raccoons and also for feral pigs, bobcats, cougars, and bears. There are six distinct breeds of coonhound.
The Bulldog is a British breed of dog of mastiff type. It may also be known as the English Bulldog or British Bulldog. It is a medium-sized, muscular dog of around 40–55 lb (18–25 kg). They have large heads with thick folds of skin around the face and shoulders and a relatively flat face with a protruding lower jaw. The breed has significant health issues as a consequence of breeding for its distinctive appearance, including brachycephaly, hip dysplasia, heat sensitivity, and skin infections. Due to concerns about their quality of life, breeding Bulldogs is illegal in Norway and the Netherlands.
The Staffordshire Bull Terrier, also called the Staffy or Stafford, is a purebred dog of small to medium size in the terrier group that originated in the northern parts of Birmingham and in the Black Country of Staffordshire, for which it is named. They descended from 19th-century bull terriers that were developed by crossing bulldogs with various terriers to create a generic type of dog generally known as bull and terriers. Staffords share the same ancestry with the modern Bull Terrier, although the two breeds developed along independent lines, and do not resemble each other. Modern Staffords more closely resemble the old type of bull terrier, and were first recognised as a purebred dog breed by The Kennel Club of Great Britain in 1935.
The Aidi is a dog breed native to the Atlas Mountains of North Africa and is used as a livestock guardian, protecting herds of sheep and goats. It is most commonly found in Morocco, which holds the standard under the Fédération Cynologique Internationale. The Aidi is also found in Algeria, Tunisia and Libya. It possesses hunting capabilities and good scenting ability. In Morocco, it is often paired in hunting with the Sloughi, which chases down prey that the Aidi has located by scent.
The Fédération Cynologique Internationale is the largest international federation of national kennel clubs and purebred registries. The FCI is based in Thuin, Belgium and has 98 members and contract partners.
Dog breeding is the practice of mating selected dogs with the intention of maintaining or producing specific qualities and characteristics. When dogs reproduce without such human intervention, their offspring's characteristics are determined by natural selection, while "dog breeding" refers specifically to the artificial selection of dogs, in which dogs are intentionally bred by their owners. Breeding relies on the science of genetics, hence a breeder who is knowledgeable on canine genetics, health, and the intended purpose of the dogs attempts to breed suitable dogs.
The American bulldog is a large, muscular breed of mastiff-type dog. Their ancestors were brought to the British North American colonies where they worked on small farms and ranches.
The Rat Terrier is an American dog breed with a background as a farm dog and hunting companion. They share much ancestry with the small hunting dogs known as feists. Common throughout family farms in the 1920s and 1930s, they are now recognized by the United (UKC) and American Kennel Clubs (AKC) and are considered a rare breed. Rat Terriers are an intelligent and active breed that can be kept both for pest control and as a family pet.
The United Kennel Club (UKC) is a kennel club founded in 1898 in the United States. In contrast with the American Kennel Club, which is non-profit and which only clubs can join, the United Kennel Club is a profit-making corporation, open to individuals.
Dog crossbreeds are dogs which have been intentionally bred from two or more recognized dog breeds. They are not dogs with no purebred ancestors, but are not otherwise recognised as breeds in their own right, and do not necessarily breed true.
The American Pit Bull Terrier (APBT) is a dog breed recognized by the United Kennel Club (UKC) and the American Dog Breeders Association (ADBA), but not the American Kennel Club (AKC). It is a medium-sized, short-haired dog, of a solid build, whose early ancestors came from England. When compared with the English Staffordshire Bull Terrier, the American Pit Bull Terrier is larger by margins of 6–8 inches (15–20 cm) in height and 25–35 pounds (11–16 kg) in weight. The American Pit Bull Terrier varies in size: males are normally about 18–21 inches (45–53 cm) in height and around 35–60 pounds (15–27 kg) in weight, while females are normally around 17–20 inches (43–50 cm) in height and 30–50 pounds (13–22 kg) in weight.
The Alaunt is an extinct type of dog which came in different forms, with the original possibly having existed in North Caucasus, Central Asia and Europe from ancient times.
The Old English Bulldog is an extinct breed of dog.
Bulldogs are a type of dog that were traditionally used for the blood sports of baiting and dog fighting, but today are kept for other purposes, including companion dogs, guard dogs and catch dogs. Bulldogs are typically stocky, powerful, square-built animals with large, strong, brachycephalic-type muzzles. "Bull" is a reference that originated in England that refers to the sport of bull-baiting, which was a national sport in England between the 13th and 18th century. It is believed that bulldogs were developed during the 16th century in the Elizabethan era from the larger mastiffs, as smaller, more compact dogs were better suited for baiting.
The Bavarian Mountain Hound is a breed of dog from Germany. As a scent hound, it has been used in Germany since the early 20th century to trail wounded game.
Bull and terrier was a common name for crossbreeds between bulldogs and terriers in the early 1800s. Other names included half-and-halfs and half-breds. It was a time in history when, for thousands of years, dogs were classified by use or function, unlike the modern pets of today that were bred to be conformation show dogs and family pets. Bull and terrier crosses were originally bred to function as fighting dogs for bull- and bear-baiting, and other popular blood sports during the Victorian era. The sport of bull baiting required a dog with attributes such as tenacity and courage, a wide frame with heavy bone, and a muscular, protruding jaw. By crossing bulldogs with various terriers from Ireland and Great Britain, breeders introduced "gameness and agility" into the hybrid mix.
The American Bully is a modern breed of dog that was developed as a companion dog, and originally standardized and recognized as a breed in 2004 by the American Bully Kennel Club (ABKC). Their published breed standard describes the dog as giving the "impression of great strength for its size". In 2008, the American Bully was recognized by the European Bully Kennel Club (EBKC), and on July 15, 2013, by the United Kennel Club (UKC). The UK Kennel Club, American Kennel Club, and International Canine Federation do not recognize the American Bully as a separate breed.
The Continental Bulldog, or Conti for short, is a newer dog breed created in Switzerland. It is officially recognized by the FCI since 2022.
