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.
The Manx cat is a breed of domestic cat originating on the Isle of Man, with a mutation that shortens the tail. Many Manx have a small stub of a tail, but Manx cats are best known as being entirely tailless; this is the most distinguishing characteristic of the breed, along with elongated hind legs and a rounded head. Manx cats come in all coat colours and patterns, though all-white specimens are rare, and the coat range of the original stock was more limited. Long-haired variants are sometimes considered a separate breed, the Cymric.
The Cymric is a Canadian cat breed. Some cat registries consider the Cymric a semi-long-haired variety of the Manx breed, rather than a separate breed. Except for the length of fur, in all other respects, the two varieties are the same, and kittens of either sort may appear in the same litter. The name comes from Cymru, the indigenous Welsh name of Wales, even though the breed is not associated with Wales. The name may have been chosen to provide a "Celtic" sounding moniker for the breed. While the breed's Manx bloodline originated from the Isle of Man, the long-haired variant is claimed to have been developed by Canada. The breed is called the Longhair Manx or a similar name by some registries.
The American Bobtail is an uncommon breed of domestic cat which was developed in the late 1960s. It is most notable for its stubby "bobbed" tail about one-third to one-half the length of a normal cat's tail. This is the result of a cat body type genetic mutation affecting the tail development, similar to that of a Manx cat. The breed is not related to other short-tailed breeds, such as the Cymric cat, or the Japanese Bobtail or Kurilian Bobtail, despite the similar name and physical type—the breeding programs are entirely unrelated, and the genetic mutation causing the bobbed tail are known to be different, as the mutation causing the American Bobtail's short tail is dominant; comparatively, the Japanese Bobtail, for example, has a tail mutation that is recessive.
The Japanese Bobtail is a breed of domestic cat with an unusual bobtail more closely resembling the tail of a rabbit than that of other cats. The breed was first developed in Japan, and registered officially in the 1960s. The breed has been known in Japan for centuries, and it frequently appears in traditional folklore and art. Japanese Bobtails are believed to be derived from domestic and feral populations of kinked-tailed cats widespread throughout Southeast Asia and southern China.
A sheep dog or sheepdog is generally a dog or breed of dogs historically used in connection with the raising of sheep. These include livestock guardian dogs used to guard sheep and other livestock and herding dogs used to move, manage and control sheep and other livestock.
The Welsh Corgi is a small type of herding dog that originated in Wales. The name corgi is derived from the Welsh words cor and ci, meaning "dwarf" and "dog", respectively.
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, brindled, or white, with or without white markings. Boxers are brachycephalic, have a square muzzle, mandibular prognathism, 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.
The Cardigan Welsh corgi is one of two different varieties of livestock-herding dog breeds known as Welsh corgis, with the other being the Pembroke Welsh corgi. It is one of the oldest breeds of the British Isles. Cardigan Welsh corgis are known to be an extremely loyal and trainable dog breed, naturally attuned to herding many different animals, from poultry and waterfowl to large livestock such as sheep and cattle. They are also versatile and can live in a variety of settings.
The Pembroke Welsh Corgi is a cattle herding dog breed that originated in Pembrokeshire, Wales. It is one of two breeds known as a Welsh Corgi, the other being the Cardigan Welsh Corgi. Pembroke Welsh Corgis descended from the Spitz family of dogs.
Docking is the removal of portions of an animal's tail. While docking and bobbing are more commonly used to refer to removal of the tail, the term cropping is used in reference to the ears. Tail docking occurs in one of two ways. The first involves constricting the blood supply to the tail with a rubber ligature for a few days until the tail falls off. The second involves the severance of the tail with surgical scissors or a scalpel. The length to which tails are docked varies by breed, and is often specified in the breed standard.
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.
A Schnauzer is a dog breed type that originated in Germany from the 14th to 16th centuries. The term comes from the German word for "snout" and means colloquially "moustache", or "whiskered snout", because of the dog's distinctively bearded snout. Initially it was called Wire-Haired Pinscher, while Schnauzer was adopted in 1879.
Canine terminology in this article refers only to dog terminology, specialized terms describing the characteristics of various external parts of the domestic dog, as well as terms for structure, movement, and temperament. This terminology is not typically used for any of the wild species or subspecies of wild wolves, foxes, coyotes, dholes, jackals or the basal caninae. Dog terminology is often specific to each breed or type of dog. Breed standards use this terminology in the description of the ideal external appearance of each breed, although similar characteristics may be described with different terms in different breeds.
The Dobermann is a German breed of medium-large domestic dog of pinscher type. It was originally bred in Thuringia in about 1890 by Louis Dobermann, a tax collector. It has a long muzzle and – ideally – an even and graceful gait. The ears were traditionally cropped and the tail docked, practices which are now illegal in many countries.
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 Armant is a breed of herding dog from Egypt. The breed is not well known outside of Egypt but is used extensively within Egypt as both a herding dog and a guard dog.
The Kurilian Bobtail is a cat breed originating from the Russian Kuril Islands, as well as Sakhalin Island and the Kamchatka peninsula of Russia. Short- or long-haired, it has a semi-cobby body type and a distinct short, fluffy tail. The back is slightly arched with hind legs longer than the front, similar to those of the Manx. The breed is also called the Kuril Islands Bobtail, Kuril Bobtail and Curilsk Bobtail, and may be referred to without "Bobtail". It is sometimes also spelled Kurilean. The original short-haired variant is a natural breed, known on the islands for over 200 years. As selectively bred pets, they have been popular in USSR and to some extent other parts of Europe, especially for their rodent-hunting abilities, since the middle of the 20th century, but remained rare in North America as of 2011.
