Double Coat
The coat of the domestic dog refers to the hair that covers its body. Dogs demonstrate a wide range of coat colors, patterns, textures, and lengths. As with other mammals, a dog's fur has many uses, including thermoregulation and protection from cuts or scratches; furthermore, a dog's coat plays an important role in the showing of purebred dogs. Breed standards often include a detailed description of the nature and attributes of that breed's ideal coat. A dog's coat is composed of two layers: a top coat of stiff guard hairs that help repel water and shield from dirt, and an undercoat of soft down hairs, to serve as insulation. Dogs with both under coat and top coat are said to have a ''double coat''. Dogs with a ''single coat'' have a coat composed solely of guard hairs, with little or no downy undercoat. The terms fur and hair are often used interchangeably when describing a dog's coat, however in general, a double coat, like that of the Newfoundland and most livestock g ...

Dog Coat Variation
The dog (''Canis familiaris'' or ''Canis lupus familiaris'') is a domesticated descendant of the wolf. Also called the domestic dog, it is derived from the extinct Pleistocene wolf, and the modern wolf is the dog's nearest living relative. Dogs were the first species to be domesticated by hunter-gatherers over 15,000 years ago before the development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids. The dog has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. Dog breeds vary widely in shape, size, and color. They perform many roles for humans, such as hunting, herding, pulling loads, protection, assisting police and the military, companionship, therapy, and aiding disabled people. Over the millennia, dogs became uniquely adapted to human behavior, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ghost Population
A ghost population is a population that has been inferred through using statistical techniques. Population studies In 2004, it was proposed that maximum likelihood or Bayesian approaches that estimate the migration rates and population sizes using coalescent theory can use datasets which contain a population that has no data. This is referred to as a "ghost population". The manipulation allows exploration in the effects of missing populations on the estimation of population sizes and migration rates between two specific populations. The biases of the inferred population parameters depend on the magnitude of the migration rate from the unknown populations. The technique for deriving ghost populations attracted criticism because ghost populations were the result of statistical models, along with their limitations. Population genetics In 2012, DNA analysis and statistical techniques were used to infer that a now-extinct human population in northern Eurasia had interbred with both the ...

Basset Fauve De Bretagne
The Basset Fauve de Bretagne is a short-legged hunting breed of dog of the scent hound type, originally from Brittany, a historical duchy of France. Description Appearance The Basset Fauve de Bretagne is a smallish hound, built along the same lines as the Basset Hound, but lighter all through and longer in the leg. Wire-coated, the coat is very harsh to the touch, dense, red-wheaten or fawn. They measure 32 – 38 cm in height and weigh between 36 - 40 lbs but due to the historically controversial practice of registering mixed litters of Griffon and Basset Fauves, sometimes a litter of bassets will produce dogs with long legs. They have coarse, dense fur which may require stripping. Although their coat repels dirt and does not mat easily, they still require weekly combing and brushing. The hair on the ears is shorter, finer and darker than that on the coat. The ears just reach the end of the nose rather than trailing on the ground and should be pleated. They should have ...

Shiba Inu
The is a breed of hunting dog from Japan. A small-to-medium breed, it is the smallest of the six original and distinct spitz breeds of dog native to Japan. Its name literally translates to "firewood dog". A small, alert, and agile dog that copes very well with mountainous terrain and hiking trails, the Shiba Inu was originally bred for hunting. It looks similar to and is often mistaken for other Japanese dog breeds such as the Akita Inu or Hokkaido, but the Shiba Inu is a different breed with a distinct blood line, temperament, and smaller size than other Japanese dog breeds. Appearance The Shiba's frame is compact with well-developed muscles."Get to Know the Shiba Inu" , 'The American Kennel Club', retrieved 14 May 2014 The Shiba Inu is double coated, with the outer coat being stiff and str ...

Cavalier King Charles Spaniel
The Cavalier King Charles Spaniel is a British breed of toy dog of spaniel type. Four colours are recognised: Blenheim (chestnut and white), 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 Cavalier King Charles changed dramatically in the late seventeenth century, when it was inter-bred with flat-nosed breeds. Until the 1920s, it shared the same history as the smaller King Charles Spaniel. Breeders attempted to recreate what they considered to be the original configuration – a dog resembling Charles II's spaniel of the English Civil War period, when supporters of the king were known as Cavaliers. History During the early part of the 18th century, John Churchill, 1st Duke of Marlborough, kept red and white King Charles type spaniels for hunting. The duke recorded that they were able to keep up with a trotting horse. His estate was named Blenheim in honour of his victory ...

Chow Chow
The Chow Chow is a spitz-type of dog breed originally from northern China. The Chow Chow is a sturdily built dog, square in profile, with a broad skull and small, triangular, erect ears with rounded tips. The breed is known for a very dense double coat that is either smooth or rough. The fur is particularly thick in the neck area, giving it a distinctive ruff or mane appearance. The coat may be shaded/self-red, black, blue, cinnamon/fawn, or cream. History The Chow Chow has been identified as a basal breed that predates the emergence of the modern breeds in the 19th Century. One writer proposed that the Chow Chow originated in China 2,000 years ago or possibly originated in Arctic Asia 3,000 years ago which migrated to Mongolia, then to China. One Chinese legend mentions large war dogs from Central Asia that resembled black-tongued lions. One Chinese ruler was said to own 5,000 Chows. The Chinese also used Chows to pull dog sleds through swampy terrain, and this wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australian Cattle Dog
The Australian Cattle Dog (ACD), or simply Cattle Dog, is a breed of herding dog originally developed in Australia for droving cattle over long distances across rough terrain. This breed is a medium-sized, short- coated dog that occurs in two main colour forms. It has either red or black hair distributed fairly evenly through a white coat, which gives the appearance of a "red" or "blue" dog. As with dogs from other working breeds, the Australian Cattle Dog is energetic and intelligent with an independent streak. It responds well to structured training, particularly if it is interesting and challenging. It was originally bred to herd by biting, and is known to nip running children. It forms a strong attachment to its owners, and can be protective of them and their possessions. It is easy to groom and maintain, requiring little more than brushing during the shedding period. The most common health problems are deafness and progressive blindness (both hereditary conditions) and ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Kelpie
The Australian Kelpie, or simply Kelpie, is an Australian sheepdog capable of mustering and droving with little or no guidance. It is a medium-sized dog and comes in a variety of colours. The Kelpie has been exported throughout the world and is used to muster livestock, primarily sheep, cattle and goats. The breed has been separated into two distinct varieties: the Show (or Bench) Kelpie and the Working Kelpie. The Show Kelpie is seen at conformation dog shows in some countries and is selected for appearance rather than working instinct, while the Working Kelpie is bred for working ability rather than appearance. History The ancestors of most Kelpies were British dogs known loosely as collies (sometimes spelled colleys). These were mostly black, or very dark brown, dogs – hence the name collie, which has the same root as coal. (The official collie breeds were not formed until about 10 or 15 years after the Kelpie was established as a breed, and the first recognised Bord ...

Chesapeake Bay Retriever
The Chesapeake Bay Retriever is a large breed of dog belonging to the retriever, gundog, and sporting breed groups. The breed was developed in the United States Chesapeake Bay area during the 19th century. Historically used by local market hunters to retrieve waterfowl, pull fishing nets, and rescue fishermen, it is today primarily a family pet and hunting companion, known for a bright and happy disposition; courage; willingness to work; alertness; intelligence; love of water; and hunting capabilities. The Chesapeake is a medium- to large-sized dog similar in appearance to the Labrador Retriever, but with a wavy coat. Appearance Distinctive features include eyes that are very clear, of yellowish or amber hue, hindquarters as high or a trifle higher than the shoulders, and a double-coat that tends to wave on shoulders, neck, back, and loins. The waterproof coat feels slightly oily and is often associated with a slight musky odor. Three basic colors are generally seen in the br ...

Liver (color)
At right is displayed the color traditionally called liver. The first recorded use of ''liver'' as a color name in English was in 1686. Liver may also refer to a group of certain types of dark brown color in dogs and horses. Said nomenclature may also refer to the color of the organ. In dogs In dogs, the Liver color is caused by dilution of the eumelanin (black) pigment by the B locus. The gene that causes Liver is recessive, so a BB or Bb dog has normal black pigment. Only a bb dog is Liver. There are several different recessive b genes, but they all turn the coat brown. They are only distinguishable through genetic testing. Liver may also be called different names such as Brown, Chocolate, or Red. Red is a very misleading term, and should be avoided when referring to the color liver because it can be confused for phaeomelanin pigment. This second pigment is what colors all the "true red" or yellow parts of a dog. Liver dilution can also be combined with other genes that ...
