Coat (dog)
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 Conformation show, 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 (dog), ...

Dog Coat Variation
The dog (''Canis familiaris'' or ''Canis lupus familiaris'') is a Domestication of vertebrates, domesticated descendant of the gray wolf. Also called the domestic dog, it was Selective breeding, selectively bred from a population of wolves during the Late Pleistocene by hunter-gatherers. The dog was the first species to be domesticated by humans, over 14,000 years ago and before the History of agriculture, development of agriculture. Due to their long association with humans, dogs have gained the ability to thrive on a starch-rich diet that would be inadequate for other Canidae, canids. Dogs have been bred for desired behaviors, sensory capabilities, and physical attributes. Dog breeds vary widely in shape, size, and color. They have the same number of bones (with the exception of the tail), powerful jaws that house around 42 teeth, and well-developed Dog sense of smell, senses of smell, hearing, and sight. Compared to humans, dogs possess a superior sense of smell and heari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Introgression
Introgression, also known as introgressive hybridization, in genetics is the transfer of genetic material from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species. Introgression is a long-term process, even when artificial; it may take many hybrid generations before significant backcrossing occurs. This process is distinct from most forms of gene flow in that it occurs between two populations of different species, rather than two populations of the same species. Introgression also differs from simple Hybridization (biology), hybridization. Simple hybridization results in a relatively even mixture; gene and allele frequencies in the first generation will be a uniform mix of two parental species, such as that observed in mules. Introgression, on the other hand, results in a complex, highly variable mixture of genes, and may only involve a minimal percentage of the donor genome. Definition Introgression or i ...

Cavalier King Charles Spaniel
The Cavalier King Charles Spaniel (CKCS) is a British list of dog breeds, breed of toy dog of spaniel type. Four colours are recognised: Blenheim (chestnut and white), Tricolor (dog), 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 of England, 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 h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. A research study has concluded that the Chow Chow dog breed originated from other indigenous dogs in central China about 8,300 years ago. The ancient breed evolved and manifests both morphological and physiological features, including its dark tongue, coat of fur, and stronger build. One Chinese legend mentions large war dogs from Central Asia that resembled black-tongued lions. One Chinese ruler was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irish Setter
The Irish Setter (, literally "red setter") is a setter, a breed of gundog, and family dog originating in Ireland. The term ''Irish Setter'' is commonly used to encompass the show-bred dog recognised by the American Kennel Club as well as the field-bred Red Setter recognised by the Field Dog Stud Book. Description Appearance The coat is moderately long, silky, and of a red or chestnut colour. It requires frequent brushing to maintain its condition and keep it mat-free. The undercoat is abundant in winter weather, and the top coat is fine. Their coats should also feather in places such as the tail, ears, chest, legs, and body. Irish Setters range in height from , males weigh and females . The FCI Breed Standard for the Irish Setter stipulates males stand tall, and females be tall. Irish Setters are deep chested dogs with small waists. An Irish Setter's life expectancy tends to be around 11 to 12 years. Temperament Irish Setters get along well with children and o ...

Australian Cattle Dog
The Australian Cattle Dog, or simply Cattle Dog, is a breed of herding dog developed in Australia for droving cattle over long distances across rough terrain. This breed is a medium-sized, short-Coat (dog), coated dog that occurs in two main colour forms. It has either red or black hair distributed fairly evenly through a white Coat (dog), coat, which gives the appearance of a "red" or "blue" dog. As with dogs from other working dog, 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 Heredity, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labrador Retrievers
The Labrador Retriever or simply Labrador or Lab is a British list of dog breeds, breed of water dog retriever gun dog. It was developed in the United Kingdom from St. John's water dogs imported from the Newfoundland Colony, colony of Newfoundland (now a Newfoundland and Labrador, province of Canada), and was named after the Labrador region of that colony. It is among the most commonly kept dogs in several countries, particularly in the Western world. Labradors are often friendly, energetic, and playful. It was bred as a sporting and hunting dog but is widely kept as a companion dog. Though content as a companion, these dogs are intelligent and require both physical and mental stimulation. It may also be trained as a guide dog, guide or assistance dog, or for rescue dog, rescue or therapy dog, therapy work. In the 1830s, the Alexander Home, 10th Earl of Home, 10th Earl of Home and his nephews, the Walter Montagu Douglas Scott, 5th Duke of Buccleuch, 5th Duke of Buccleuch and ...

Australian Kelpie
The Australian Kelpie, or simply Kelpie, is an Australia, Australian Herding dog, sheepdog capable of Muster (livestock), 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), 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 its working ability. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chesapeake Bay Retriever
The Chesapeake Bay Retriever is a large dog breed, breed of dog belonging to the retriever, Gun dog, gundog, and sporting Breed Groups (dog), 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 Anseriformes, waterfowl, pull fishing nets, and rescue Fisherman, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liver (color)
Liver is a color name for a kind of brown, first recorded as such in English language, English in 1686. It may refer to the color of the Liver, organ. In particular, Liver describes a dark brown color in the coats of dogs and horses. 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 dilute a dog's coat. The D locus dilutes black pigment ...

Dorsum (anatomy)
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...
