Hairless Dog
A hairless dog is a dog with a Genetics, genetic disposition for hairlessness and hair loss. There are two known types of genetic hairlessness, a Dominant gene, dominant and a recessive type. The dominant type is caused by ectodermal dysplasia as a result of a mutation in the ''FOXI3'' autosomal gene. Dominant genes Dogs with dominant genes for hairlessness can pass their attributes to their offspring in natural conditions; that is, not under the control of humans. Therefore, it is possible that, in some parts of the world, groups of hairless dogs came into existence without human Selective breeding, intervention. Later in history, people developed these groups into recognized breeds. Worldwide recognized breeds at this time are the Chinese Crested Dog, the Xoloitzcuintle (Mexican Hairless Dog), the Peruvian Hairless Dog, Peruvian Inca Orchid. The Argentine Pila, the Hairless Khala from Bolivia, and the Ecuadorian Hairless Dog are not registered hairless dog breeds. Other bree ...

Argentine Pila
The Argentine Pila or is an Argentine breed of hairless dog. It was recognised by the Asociación Canina Argentina in 2007. It forms part of the large group of South American hairless breeds and types, but is distinct from other modern breeds such as the Chinese Crested, the Peruvian Hairless and the Xoloitzcuintle. It is generally dark-skinned, or light-skinned with dark spots. It is estimated that approximately 1,700 of these dogs are in Argentina, predominantly in the Salta province Salta () is a Provinces of Argentina, province of Argentina, located in the northwest of the country.

Dog Anatomy
Dog anatomy comprises the anatomical study of the visible parts of the body of a dog, domestic dog. Details of structures vary tremendously from dog breed, breed to breed, more than in any other animal species, wild or domesticated, as dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier that stood only at the shoulder, in length along the head and body, and weighed only . The heaviest dog was an English Mastiff named Zorba (dog), Zorba, which weighed . The tallest known adult dog is a Great Dane that stands at the shoulder. Anatomy Muscles The following is a list of the muscles in the dog, along with their origin, insertion, action and innervation. Extrinsic muscles of the thoracic limb and related structures: Descending superficial pectoral: originates on the first sternebrae and inserts on the greater tubercle of the humerus. It both adducts the limb and also prevents the limb from being abducted during weight bearing. It i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jonangi
The Jonangi, also known as Jonangi Jagilam or Kolleti Jagilam is an Indian dog breed, mostly found in the separated state of Andhra Pradesh, some parts of Karnataka, and all along the east coast from West Bengal to Tamil Nadu. It was once abundantly found in and around Kolleru Lake in West Godavari and Krishna Districts of Andhra Pradesh. This dog has very short, smooth hair. It is used as a hunting and herding dog by people who have this breed. The Jonangi is not recognized by major kennel clubs in India, but this breed is locally shown at beach festivals in Andhra Pradesh. Temperament The Jonangi is a one-person or one-family dog. It is an agile dog, with long strides that can cover very large distances. While a few dogs exhibit nervousness, most Jonangis make excellent working partners, guarding large farms and even houses. They are known to coexist with farm animals such as poultry, goats, sheep and cattle. Jonangis are known for digging decently sized ditches to l ...

American Hairless Terrier
The American Hairless Terrier is a breed of companion dog from the United States that was developed from naturally hairless Rat Terriers. History In 1972, a completely hairless bitch pup was whelped in a litter of purebred Rat Terriers and adopted by Willie and Edwin Scott of Louisiana. Named Josephine, the bitch conformed to the Rat Terrier type in every way except for her coat, so the Scotts bred her. Her first litter produced another hairless bitch pup, Gypsy. Neither bitch whelped another hairless pup in multiple litters until, in 1981 at the age of nine, Josephine produced two more hairless pups, a dog and a bitch. In 1983 the dog, Snoopy, was mated to his hairless sisters and many more hairless pups were whelped, establishing the foundation stock for the new breed. Originally registered as a hairless variety of Rat Terriers, eventually the Scotts adopted a different breed name for their unique line and established a separate breed club, the American Hairless Terrier Associati ...

Conformation Show
A dog show is an animal show; it is an event where dogs are exhibited. A conformation show, also referred to as a '' breed show'', is a kind of dog show in which a judge, familiar with a specific dog breed, evaluates individual purebred dogs for how well the dogs ''conform'' to the established breed type for their breed, as described in a breed's individual breed standard. Dog shows can be in the means of evaluating dogs for breeding purposes. A conformation championship from a recognised national kennel club is generally considered as an indication of merit. Many breeders consider championships a prerequisite for breeding. Some critics argue that the shows can encourage selective breeding of traits and lower genetic diversity. The first modern conformation dog show was held in Newcastle Town Hall in Newcastle upon Tyne, England, in June 1859. Judging A conformation dog show is not a comparison of one dog to another but a comparison of each dog to a judge's mental imag ...

Heterozygous
Zygosity (the noun, zygote, is from the Greek "yoked," from "yoke") () is the degree to which both copies of a chromosome or gene have the same genetic sequence. In other words, it is the degree of similarity of the alleles in an organism. Most eukaryotes have two matching sets of chromosomes; that is, they are diploid. Diploid organisms have the same locus (genetics), loci on each of their two sets of homologous chromosomes except that the sequences at these loci may differ between the two chromosomes in a matching pair and that a few chromosomes may be mismatched as part of a chromosomal Sex-determination system#Chromosomal determination, sex-determination system. If both alleles of a diploid organism are the same, the organism is #Homozygous, homozygous at that locus. If they are different, the organism is #Heterozygous, heterozygous at that locus. If one allele is missing, it is #Hemizygous, hemizygous, and, if both alleles are missing, it is #Nullizygous, nullizygous. The ...

Abyssinian Sand Terrier
African hairless dogs, also known as Abyssinian sand terriers and African sand dogs among many other names, were hairless dogs from Africa. It is unknown if any examples still exist. This "breed" of dog is known for being “semi-wild”, meaning they tend to follow rather than live with the cattle breeders; though they occasionally serve as valuable companions on hunting trips. The many names of this “breed” include the words Egyptian, Abyssinian, and Zulu, which simply suggests that the genes for hairlessness have appeared independently in multiple areas of the continent as a cooling system in high heat. A number of early European accounts from Africa mention a small hairless dog. It was described as fast moving with a short, sharp bark, and it was said to be either sandy-coloured or blue-black. Contemporary reports indicated that it may or may not have had a crest of stiff hair on its head and a tuft of hair on its tail, although photographs of it fail to show any hair. Thr ...

Peruvian Hairless Dog
The Peruvian Hairless Dog or is a Peruvian breed of hairless dog. It is the only living breed of dog indigenous to Peru. As in other hairless breeds, coated examples can also occur. In hairless examples the skin may be any one of a wide variety of colors, with or without limited unpigmented areas, usually the legs, tail or chest; any hairs may be of any colour. In coated dogs, the coat may be of any colour but merle. Hairless dogs are associated with the Andean civilizations. The modern breed is recognized as a part of the national cultural heritage. Naming The dog has been known by many names, among them ''Allqu'' (in Inca times), , , (which may derive from , 'woman', rather than indicating a Chinese origin), , , , and . History The Peruvian Hairless Dog is often perceived to be an Incan dog because it is known to have been kept during the Inca Empire (the Spaniards classified them as one of the six different breeds of dogs in the empire), and they were also kept ...

Xoloitzcuintle
The Xoloitzcuintle (or Xoloitzquintle, Xoloitzcuintli, or Xolo) is one of several breeds of hairless dog. It is found in standard, intermediate, and miniature sizes. The Xolo also comes in a coated variety, totally covered in fur. Coated and hairless can be born in the same litter as a result of the same combination of genes. The hairless variant is known as the Perro pelón mexicano or Mexican hairless dog. It is characterized by its wrinkles and dental abnormalities. In Nahuatl, from which its name originates, it is ''xōlōitzcuintli'' (singular) and ''xōlōitzcuintin'' (plural).''Nahuatl Dictionary.'' (1997). Wired Humanities Project. University of Oregon.
