Sighthound
Sighthounds, also called gazehounds, are a Dog type, type of dog, hounds that hunt primarily by sight and speed, rather than by scent and endurance as scent hounds do. Appearance These dogs specialize in pursuing prey, keeping it in sight, and overpowering it by their great speed and agility. They must be able to detect motion quickly, so they have keen vision. Sighthounds must be able to capture fast, agile prey such as deer, and hares, so they have a very flexible back and long legs for a long stride, a deep chest to support an unusually (compared to other dogs) large heart, very efficient lungs for both Anaerobic exercise, anaerobic and Aerobic exercise, aerobic sprints, and a lean, wiry body to keep their weight at a minimum. Sighthounds have unique anatomical and physiological features likely due to intentional selection for hunting by speed and sight; laboratory studies have established reference intervals for hematology and serum biochemical profiles in sighthounds, some ...

Lure Coursing
Lure coursing is a sport for dogs that involves chasing a mechanically operated lure. Competition is typically limited to dogs of purebred sighthound breeds. The AKC has a pass/fail trial for all breeds called the Coursing Ability Test (CAT) and a timed 100 yard dash called Fast CAT where the dog's speed is converted to points. Lure course In lure coursing, dogs chase an artificial lure across a field, following a pattern that is meant to simulate live coursing. A typical lure course in the United States is between long. In Europe, as well as the rest of the world, the course length can be over 1000 meters, and often incorporates some obstacles or jumps. The course must have a minimum number of turns in order to simulate prey (the jack-rabbit or hare) changing direction in a chase. The fields can be fenced or not. If a dog is lure focused they will typically follow the lure from start to finish and not run off course. Dogs with some considerable lure experience, termed "lur ...

Saluki Dog Breed
The Saluki, also known as the Persian Greyhound, is a standardised breed developed from sighthounds – dogs that hunt primarily by sight rather than scent – that was once used by nomadic tribes to run down game animals. The dog was originally bred in the Fertile Crescent. The modern breed is typically deep-chested and long-legged, and similar dogs appear in medieval and ancient art. The breed is most closely related to the Afghan hound, a basal breed that predates the emergence of modern breeds in the 19th century, and the Saluki has been purebred both in the Middle East, including by royalty, since at least that era, and in the West (especially in Britain and Germany) since the 1840s (with breed standards established in the West and the Middle East around the 1920s–1930s), though as a free-breeding landrace, similar dogs are common as feral animals in the Middle East. A related standardised breed is the north African Sloughi. Name The origins of the name of the breed ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lurcher
A lurcher is a cross-bred dog resulting from mating a Greyhound or other sighthound with a dog of another type, commonly a herding dog or a terrier. The lurcher was for hundreds of years strongly associated with poaching; in modern times it is kept as a hunting dog or companion dog. History ''Lurcher'' is an old English term for a cross-bred dog - specifically the result of mating a sighthound with a dog of another type, typically a working breed. The term 'lurcher' was first used with this meaning in 1668; it is considered to be derived from the verb 'lurch', apparently a variant form of 'lurk', and meaning 'lurk' or 'steal'. In England from 1389, the right to keep a dog of any kind used in hunting - specifically stated in the Act of Parliament: ''None shall hunt but they which have sufficient living'' in the Anglo-Norman and English of the time: ''null leverer, ne lerce, nautre chien pur chacer'translated as, no "''Greyhound, Hound nor other Dog to hunt;'' – wa ...

Hound
A hound is a type of hunting dog used by hunters to track or chase prey. Description Hounds can be contrasted with gun dogs that assist hunters by identifying prey and/or recovering shot quarry. The hound breeds were the first hunting dogs. They have either a powerful sense of smell, great speed, or both. There are three types of hound, with several breeds type: * Sighthounds (also called ''gazehounds'') follow prey predominantly by speed, keeping it in sight. These dogs are fast and assist hunters in catching game: fox, hare, deer, and elk. * Scenthounds follow prey or others (like missing people) by tracking its scent. These dogs have endurance, but are not fast runners. * The remaining breeds of hound follow their prey using both sight and scent. They are difficult to classify, as they are neither strictly sighthounds nor strictly scenthounds. List of hound breeds * Afghan Hound * Africanis * Alpine Dachsbracke * American Foxhound * American Leopard Hound * Andalusian H ...

Longdog
A long dog (also long-dog or longdog) is any dog of sighthound type, whether pure-bred or not. It is usually a cross-breed between two sighthounds of different breeds, one of which is usually a Greyhound It is distinct from the lurcher, which is a cross between a sighthound and a working dog, usually a terrier or herding dog. And it is larger than a Feist, which is an American cross.Long dog , in: '''', online edition. Oxford: . Accessed May 2021. .

Afghan Hound
The Afghan Hound is a hound that is distinguished by its thick, fine, silky coat and its tail with a ring curl at the end. The breed is selectively bred for its unique features in the cold mountains of Afghanistan. Its local name is ( ps, تاژي سپی) or ( prs, سگ تازی). Other names for this breed are Tāzī, Balkh Hound, Baluchi Hound, Barakzai Hound, Shalgar Hound, Kabul Hound, Galanday Hound or sometimes incorrectly African Hound. They have the ability to run and turn well. History The Afghan Hound has been identified as a basal breed that predates the emergence of the modern breeds in the 19th century. It is most closely related to the Saluki. Connections with other types and breeds from the same area may provide clues to the history. A name for a desert coursing Afghan hound, Tazi (Sag-e-Tazi), suggests a shared ancestry with the very similar Tasy breed from the Caspian Sea area of Russia and Turkmenistan. Other types or breeds of similar appearance are the Ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scent Hound
Franz Rudolf Frisching in the uniform of an officer of the Bernese Huntsmen Corps with his Berner Laufhund, painted by Jean Preudhomme in 1785 Scent hounds (or scenthounds) are a Dog type, type of hound that primarily hunts by scent rather than visual perception, sight. These breeds are hunting dogs and are generally regarded as having some of the most sensitive noses among dogs. Scent hounds specialize in following scent or smells. Most of them tend to have long, drooping ears and large nasal cavities to enhance smell sensitivity. They relatively need to have high endurance to be able to keep track of scent over long distances and rough terrain. It is believed that they were originally bred by the Celts. Description Hounds are hunting dogs that either hunt by following the scent of a game animal (''scent hounds'') or by following the animal by sight (sighthounds). There are many breeds in the ''scent hound type'', and scent hounds may do other work as well, so exactly which b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coursing
Coursing by humans is the pursuit of game or other animals by dogs—chiefly greyhounds and other sighthounds—catching their prey by speed, running by sight, but not by scent. Coursing was a common hunting technique, practised by the nobility, the landed and wealthy, as well as by commoners with sighthounds and lurchers. In its oldest recorded form in the Western world, as described by Arrian, it was a sport practised by all levels of society, which remained the case until Carolingian period forest law appropriated hunting grounds, or commons, for the king, the nobility, and other land owners. It then became a formalised competition, specifically on hare in Britain, practised under rules, the ''Laws of the Leash''. As a zoological term, it refers to predation by running down prey over long distances, as opposed to stalking, in which a stealthy approach is followed by a short burst of sprinting.

Dog Racing
Greyhound racing is an organized, competitive sport in which greyhounds are raced around a track. There are two forms of greyhound racing, track racing (normally around an oval track) and coursing; the latter is now banned in most countries. Track racing uses an artificial lure (usually a form of windsock) that travels ahead of the greyhounds on a rail until the greyhounds cross the finish line. As with horse racing, greyhound races often allow the public to bet on the outcome. In many countries, greyhound racing is purely amateur and solely for enjoyment. In other countries, particularly Australia, Ireland, the United Kingdom, and the United States, greyhound racing is similar to horse racing in that it is part of the gambling industry. Animal rights and animal welfare groups have been critical of the welfare of greyhounds in the commercial racing industry for many years which has contributed to the reforms of the industries in recent years. A greyhound adoption movement spea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retinal Ganglion Cell
A retinal ganglion cell (RGC) is a type of neuron located near the inner surface (the ganglion cell layer) of the retina of the human eye, eye. It receives visual information from photoreceptor cell, photoreceptors via two intermediate neuron types: Bipolar cell of the retina, bipolar cells and retina amacrine cells. Retina amacrine cells, particularly narrow field cells, are important for creating functional subunits within the ganglion cell layer and making it so that ganglion cells can observe a small dot moving a small distance. Retinal ganglion cells collectively transmit image-forming and non-image forming visual information from the retina in the form of action potential to several regions in the thalamus, hypothalamus, and mesencephalon, or midbrain. Retinal ganglion cells vary significantly in terms of their size, connections, and responses to visual stimulation but they all share the defining property of having a long axon that extends into the brain. These axons form th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hunting
Hunting is the human activity, human practice of seeking, pursuing, capturing, or killing wildlife or feral animals. The most common reasons for humans to hunt are to harvest food (i.e. meat) and useful animal products (fur/hide (skin), hide, bone/tusks, horn (anatomy), horn/antler, etc.), for recreation/taxidermy (see trophy hunting), to remove predators dangerous to humans or domestic animals (e.g. wolf hunting), to pest control, eliminate pest (organism), pests and nuisance animals that damage crops/livestock/poultry or zoonosis, spread diseases (see varmint hunting, varminting), for trade/tourism (see safari), or for conservation biology, ecological conservation against overpopulation and invasive species. Recreationally hunted species are generally referred to as the ''game (food), game'', and are usually mammals and birds. A person participating in a hunt is a hunter or (less commonly) huntsman; a natural area used for hunting is called a game reserve; an experienced hun ...
