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, skull shape, tail phenotype, fur type, body shape, and coat colour. However, there is 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 Pomeranian is a breed of dog of the Spitz type that is named for the Pomerania region in north-west Poland and north-east Germany in Central Europe. Classed as a toy dog breed because of its small size, the Pomeranian is descended from larger Spitz-type dogs, specifically the German Spitz.
The Papillon, also called the Continental Toy Spaniel, is a breed of dog, of the spaniel type. One of the oldest of the toy spaniels, it derives its name from its characteristic butterfly-like look of the long and fringed hair on the ears. A Papillon with dropped ears is called a Phalene.
The Cavalier King Charles Spaniel (CKCS) is a British breed of toy dog of spaniel type. Four colours are recognised: Blenheim, tricolour (black/white/tan), black and tan, and ruby; the coat is smooth and silky. The lifespan is usually between eight and twelve years.
The Goldendoodle is a designer dog created by crossbreeding a Golden Retriever and a Poodle. First widely bred in the 1990s, they are bred in three different sizes—each corresponding to the size of Poodle used as a parent.
A labradoodle is a crossbreed dog created by crossing a Labrador Retriever and a Standard or Miniature Poodle. Labradoodles were intended to be a good choice for people with canine dander allergies.
The cockapoo, also known as a cockerpoo, is a dog crossbreed bred from the Cocker Spaniel and the Poodle, most commonly the Miniature Poodle.
The Australian Shepherd is a breed of herding dog from the United States. The name of the breed is technically a misnomer, as it was developed in California in the 19th century. It is believed to have its origins in sheepdog breeds from northwest Spain, as well as collies imported, alongside sheep, from Australia and New Zealand; the breed reportedly took its name from this trade. Originally used solely as a herding dog, the Australian Shepherd has become one of the most popular companion dog breeds in North America.
The Parson Russell Terrier is a breed of small white terrier that was the original Fox Terrier of the 18th century. The breed is named after the Reverend Jack Russell, credited with the creation of this type of dog. It is the recognised conformation show variety of the Jack Russell Terrier and was first recognised in 1990 in the United Kingdom as the Parson Jack Russell Terrier. In America, it was first recognised as the Jack Russell Terrier in 1997. The name was changed to its current form in 1999 in the UK and by 2008 all international kennel clubs recognised it under the new name.
A mongrel, mutt, or mixed-breed dog is a dog that does not belong to one officially recognized breed, including those that result from intentional breeding. Although the term mixed-breed dog is sometimes preferred, many mongrels have no known purebred ancestors.
A spaniel is a type of gun dog. Spaniels were especially bred to flush game out of denser brush. By the late 17th century, spaniels had been specialized into water and land breeds. The extinct English Water Spaniel was used to retrieve water fowl shot down with arrows. Land spaniels were setting spaniels—those that crept forward and pointed their game, allowing hunters to ensnare them with nets, and springing spaniels—those that sprang pheasants and partridges for hunting with falcons, rabbits and smaller mammals such as rats and mice for hunting with greyhounds. During the 17th century, the role of the spaniel dramatically changed as Englishmen began hunting with flintlocks for wing shooting. Charles Goodall and Julia Gasow (1984) write that spaniels were "transformed from untrained, wild beaters, to smooth, polished gun dogs."
Gun dogs or bird dogs are types of hunting dogs developed to assist hunters in finding and retrieving game, typically various fowls that are shot down on the flight. The term hunting dog is broad and includes all breeds and skills of hunting canines, but "gun dogs" refers to canines that are trained to work alongside a loud firearm while hunting or retrieving game. Gun dogs are divided into three main categories: pointers and retrievers, setters and spaniels, and water dogs.
The English Cocker Spaniel is a breed of gun dog. It is noteworthy for producing one of the most varied numbers of pups in a litter among all dog breeds. The English Cocker Spaniel is an active, good-natured, sporting dog standing well up at the withers and compactly built. There are "field" or "working" cockers and "house" cockers. It is one of several varieties of spaniel and is the foundation of its American cousin, the American Cocker Spaniel. The English Cocker is closer to the working-dog form of the Field Spaniel and the English Springer Spaniel. English Cocker Spaniels are also known as the "Merry Spaniel" due to their constantly wagging tail.
Dog crossbreeds, sometimes called designer dogs, 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.
A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. Crossbreeding, sometimes called "designer crossbreeding", is the process of breeding such an organism. While crossbreeding is used to maintain health and viability of organisms, irresponsible crossbreeding can also produce organisms of inferior quality or dilute a purebred gene pool to the point of extinction of a given breed of organism.
The Old English Sheepdog is a large breed of dog that emerged in England from early types of herding dog. Obsolete names for the breed include Shepherd's Dog and bob-tailed sheep-dog. The nickname Bob-tail originates from how dogs of the breed traditionally had their tails docked. Old English Sheepdogs can grow very long coats with fur covering the face and eyes and do not shed unless brushed.
The Australian Silky Terrier or simply Silky Terrier is a small breed of dog of the terrier dog type. The breed was developed in Australia, although the ancestral types and breeds were from Great Britain. It is closely related to the Australian Terrier and the Yorkshire Terrier. The breed is called the Silky Terrier in North America, but is called the Australian Silky Terrier in its country of origin and in the rest of the world.
The English Miniature Bull Terrier is a breed with origins in the extinct English White Terrier, the Dalmatian and the Bulldog. The first existence is documented in 1872 in The Dogs of British Island.
The Japanese Spitz is a small to medium breed of dog of the Spitz type. There are varying standards around the world as to the ideal size of the breed, but they are always larger than their smaller cousins, the Pomeranian. They were developed in Japan in the 1920s and 1930s by breeding a number of other Spitz type dog breeds together. They are recognized by the vast majority of the major kennel clubs, except the American Kennel Club due to it being of similar appearance to the white Pomeranian, American Eskimo Dog and Samoyed. While they are a relatively new breed, they are becoming widely popular due to their favorable temperament and other features.
