The cephalic index or cranial index is a number obtained by taking the maximum width of the head of an organism, multiplying it by 100 and then dividing it by their maximum length. The index was once used to categorize human beings in the first half of the 20th century, but today it is used to categorize dogs and cats.
A hound is a type of hunting dog used by hunters to track or chase prey.
Scent hounds are a type of hound that primarily hunts by scent rather than sight. These breeds are hunting dogs and are generally regarded as having some of the most sensitive noses among dogs. Scent hounds specialize in following scent or smells. Most of them tend to have long, drooping ears and large nasal cavities to enhance smell sensitivity. They need to have relatively high endurance to be able to keep track of scent over long distances and rough terrain. It is believed that they were first bred by the Celts by crossbreeding mastiff-type dogs with sighthounds. The first established scent hounds were St. Hubert Hounds bred by monks in Belgium during the Middle Ages.
A retriever is a type of gun dog that retrieves game for a hunter. Generally gun dogs are divided into three major classifications: retrievers, flushing spaniels, and pointing breeds. Retrievers were bred primarily to retrieve birds or other prey and return them to the hunter without damage; retrievers are distinguished in that nonslip retrieval is their primary function. As a result, retriever breeds are bred for soft mouths and a great willingness to please, learn, and obey. A soft mouth refers to the willingness of the dog to carry game in its mouth without biting into it. "Hard mouth" is a serious fault in a hunting dog and is very difficult to correct. A hard-mouthed dog renders game unpresentable or at worst inedible.
A hunting dog is a canine that hunts with or for hunters. There are several different types of hunting dog developed for various tasks and purposes. The major categories of hunting dog include hounds, terriers, cur type dogs, and gun dogs. Further distinctions within these categories can be made, based upon the dog's skills and capabilities. They are usually larger and have a more sensitive smell than normal dogs.
The Pyrenean Sheepdog, the Chien de Berger des Pyrénées in French, is a small to medium-sized breed of herding dog from the Pyrenees Mountains region of France. It is found herding flocks of sheep throughout the Pyrenees alongside the much larger Pyrenean Mountain Dog which is kept as a flock guardian.
A cur was a dog breed used by cattle drovers in England. The breed is now extinct. In the United States, a short-haired dog used in hunting and herding is called "cur-tailed", or "cur" for short.
A bichon is a distinct type of toy dog; it is typically kept as a companion dog. Believed to be descended from the Barbet, it is believed the bichon-type dates to at least the 11th century; it was relatively common in 14th-century France, where they were kept as pets of the royalty and aristocracy. From France, these dogs spread throughout the courts of Europe, with dogs of very similar form being seen in a number of portraits of the upper classes of Germany, Portugal and Spain; from Europe, the type also spread to colonies in Africa and South America. The name "bichon" is believed to be a contraction of "barbichon", which means "little barbet".
The Pointer, sometimes called the English Pointer, is a medium-sized breed of pointing dog developed in England. Pointers are used to find game for hunters, and are considered by gundog enthusiasts to be one of the finest breeds of its type; however, unlike most other hunting breeds, its purpose is to point, not retrieve game.
The Grand Bleu de Gascogne is a breed of hounds of the scenthound type, originating in France and used for hunting in packs. Today's breed is the descendant of a very old type of large hunting dog, and is an important breed in the ancestry of many other hounds.
A natural bobtail is an animal's tail which due to a mutated gene grows unusually short or is missing completely. The genes for the shortened tail may be dominant or recessive.
Follicular dysplasia is a genetic disease of dogs causing alopecia, also called hair loss. It is caused by hair follicles that are misfunctioning due to structural abnormality. There are several types, some affecting only certain breeds. Diagnosis is achieved through a biopsy, and treatment is rarely successful. Certain breeds, such as the Mexican Hairless Dog and Chinese Crested Dog, are bred specifically for alopecia.
The Billy is a large scenthound originating from central western France.
The Kerry Beagle is the only extant scent hound breed native to Ireland.
The Himalayan Sheepdog, known locally by various names including the Bhote, Bangara or Gaddi Kutta, and sometimes called the Himalayan Mastiff, is a breed of livestock guardian dog from the Himalayas. The Himalayan Sheepdog is found in the Himalayan foothills from eastern Nepal to Kashmir. The breed is primarily used as a livestock guardian dog, protecting flocks of yak and sheep from various predators, and as a property guardian dog; unusually for a livestock guardian, the breed is also used to assist with herding. The Himalayan Sheepdog is also used to assist in hunting.
Dog types are broad categories of domestic dogs based on form, function, or style of work, lineage, or appearance. Some may be locally adapted dog types that may have the visual characteristics of a modern purebred dog. In contrast, modern dog breeds strictly adhere to long-established breed standards,[note 1] that began with documented foundation breeding stock sharing a common set of inheritable characteristics, developed by long-established, reputable kennel clubs that recognize the dog as a purebred.
The Tibetan Kyi Apso is a medium to large sized breed of livestock guardian dog originating from Tibet and the Himalayas. It is considered an ancient and rare landrace, similar in appearance and stature to its relative, the Tibetan Mastiff.
Bassets are a sub-type of scenthound deliberately bred with short legs, that are used for hunting where the hunters accompany the hunting hounds on foot.
