Dwarfing
Dwarfing is a process in which a breed of animals or cultivar of plants is changed to become significantly smaller than standard members of their species. The effect can be induced through human intervention or non-human processes, and can include genetic, nutritional or hormonal means. Used most specifically, dwarfing includes pathogenic changes in the structure of an organism (for example, the bulldog, a genetically achondroplastic dog breed), in contrast to non-pathogenic proportional reduction in stature (such as the whippet, a small sighthound dog breed). Animals In animals, including humans, dwarfism has been described in several ways. Shortened stature can result from growth hormone deficiency, starvation, portal systemic shunts, renal disease, hypothyroidism diabetes mellitus and other conditions. Any of these conditions can be established in a population through genetic engineering, selective breeding, or insular dwarfism, or some combination of the above. Dwarfing ca ...

Breed
A breed is a specific group of domestic animals having homogeneous appearance (phenotype), homogeneous behavior, and/or other characteristics that distinguish it from other organisms of the same species. In literature, there exist several slightly deviating definitions. Breeds are formed through genetic isolation and either natural adaptation to the environment or selective breeding, or a combination of the two. Despite the centrality of the idea of "breeds" to animal husbandry and agriculture, no single, scientifically accepted definition of the term exists. A breed is therefore not an objective or biologically verifiable classification but is instead a term of art amongst groups of breeders who share a consensus around what qualities make some members of a given species members of a nameable subset. Another point of view is that a breed is consistent enough in type to be logically grouped together and when mated within the group produce the same type. When bred together, ind ...

Miniature Pinscher
The Miniature Pinscher, also known as the Zwergpinscher and Mini Pin, is a small breed of dog of the pinscher type originating in Germany. The breed's earliest ancestors may have included the German Pinscher mixed with Italian greyhounds and dachshunds. Historical artifacts and paintings place the Miniature Pinscher as a very old breed, but factual documentation began less than 200 years ago, leaving its actual origins to debate. Many historians and those who have researched the background of the breed agree that this heritage is most likely correct, adding the shorthaired German Pinscher to the family tree. The international kennel club, the Fédération Cynologique Internationale, lists the Miniature Pinscher in Group 2, Section 1.1 ''Pinscher'', along with the Doberman pinscher, Dobermann, the German Pinscher, the Austrian Pinscher, and the other Toy Pinscher, the Affenpinscher. Other kennel clubs list the Miniature Pinscher in the Toy Group or Companion Group. Etymology The m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whippet
The Whippet is a dog breed of medium size. It is a sighthound breed that originated in England, descended from the Greyhound. Whippets today still strongly resemble a smaller Greyhound. Part of the hound group, Whippets have relatively few health problems other than arrhythmia. Whippets also participate in dog sports such as lure coursing, agility, dock diving and flyball. The name is derived from an early 17th-century word, now obsolete, meaning "to move briskly". There has been continuity in describing Greyhound-types of different sizes: large, medium and small, recorded in hunting manuals and works on natural history from the Middle Ages. Edward of Norwich, 2nd Duke of York confirmed in his early 15th-century translation and additions to the original late 14th-century French '' Livre de chasse'' the advantage of maintaining the great, the middle, and the small size of greyhound for different sorts of game. The English physician and academic John Caius refers in his 16th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chihuahua (dog)
The Chihuahua or es, Chihuahueño, italic=no is a Mexican breed of toy dog. It is named for the Mexican state of Chihuahua and is among the smallest of all dog breeds. It is usually kept as a companion animal or for showing. History DNA studies suggest that native American dogs entered North America from Siberia roughly 10,000 years ago, and were then isolated for some 9000 years until the arrival of the first Europeans; these pre-contact dogs exhibited a unique genetic signature that is now almost gone. A study based on sequencing of ancient dog genomes, published in 2020, suggests that this pre-colonial ancestry survives in two Mexican breeds, to the extent of about 4% in the Chihuahua (and some 3% in the Xoloitzcuintli). Colonial records refer to small, nearly hairless dogs at the beginning of the nineteenth century; one claims that sixteenth-century conquistadores found them plentiful in the region later known as Chihuahua.

Mini Satin
The Mini is a small, two-door, four-seat car, developed as ADO15, and produced by the British Motor Corporation (BMC) and its successors, from 1959 through 2000. Minus a brief hiatus, original Minis were built for four decades and sold during six, from the last year of the 1950s into the last year of the 20th century, over a single generation, as fastbacks, estates, and convertibles. The original Mini is considered an icon of 1960s British popular culture. Its space-saving transverse engine and front-wheel drive layout – allowing 80% of the area of the car's floorpan to be used for passengers and luggage – influenced a generation of car makers. In 1999, the Mini was voted the second-most influential Car of the Century, car of the 20th century, behind the Ford Model T, and ahead of the Citroën DS and Volkswagen Beetle.

Mini Rex
Mini Rex is a breed of domestic rabbit that was created in 1984 in Florida by the late Monna Berryhill of Texas. The Rex mutation, derived in France in the 19th century, is recessive and causes the hair to protrude outwards from the body, instead of lying flat, and the guard hairs to be shortened to the length of the undercoat. The small size, plush coat and friendly personalities of Mini Rex rabbits make them one of the most popular rabbit breeds in the United States. They were first recognized by the American Rabbit Breeders Association (ARBA) in 1988, and have been very popular with exhibitors ever since. They weigh from 3.5 to 4 pounds when fully grown. They are short and rather close coupled. The ideal length of fur is 5/8 inch, and the fur has a lustrous appearance, good body, and a plush-like effect which offers a distinct springy resistance to the touch. The Mini Rex Standard For competitions, a Mini Rex should have a well-rounded back, with well-developed and fille ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Netherland Dwarf
The Netherland Dwarf is a breed of domestic rabbit that originated in the Netherlands. Weighing , the Netherland Dwarf is one of the smallest rabbit breeds. Its popularity as a pet or show rabbit may stem from its neotenic appearance. The Netherland Dwarf is recognised by both the American Rabbit Breeders Association (ARBA) and the British Rabbit Council (BRC). The Netherland Dwarf is often confused with the Polish breed of rabbit, but the latter has longer ears, a non-brachycephalic head and less cobbiness. History The Netherland Dwarf breed was first produced in the Netherlands in the early 20th century. Small Polish rabbits were bred with smaller wild rabbits; after several generations the resulting animal was a very small domestic rabbit available in a wide variety of colours and patterns. Netherland Dwarfs were first imported into the United Kingdom in 1948. In the 1960s and 1970s the United States imported its first Netherland Dwarf rabbits. The breed was accepted b ...

Holland Lop
Holland Lop is a breed of rabbit that was recognized by the American Rabbit Breeders Association (ARBA) in 1979 and by the Netherlands' Governing Rabbit Council in 1984. The Holland Lop, with a maximum weight of (as stipulated by ARBA), is one of the smallest lop-eared breeds. Holland Lops are one of the most popular rabbit breeds in the United States and the United Kingdom. They were first bred by Dutch breeder Adrian de Cock, as a hybrid of the French Lop and the Netherland Dwarf. Holland Lops are miniature rabbits that only weigh from about 2 to 4 pounds. They are muscular in relation to their compact frame, and have a wide variety of coat colours. Their lopped ears are one of their most distinctive features. History The history of Holland Lops began with Dutch breeder Adrian de Kock from Tilburg, Netherlands. Holland Lops were acknowledged by the American Rabbit Breed Association (ARBA) in 1979 and made known to the public in 1980. When Adrian de Cock realized that Fre ...
