Sighthound
Sighthounds, also called gazehounds, are a 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 and 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 of which are shared by all sighthounds an ...

Depth Perception
Depth perception is the ability to perceive distance to objects in the world using the visual system and visual perception. It is a major factor in perceiving the world in three dimensions. Depth perception happens primarily due to stereopsis and accommodation of the eye. Depth sensation is the corresponding term for non-human animals, since although it is known that they can sense the distance of an object, it is not known whether they perceive it in the same way that humans do. Depth perception arises from a variety of depth cues. These are typically classified into binocular cues and monocular cues. Binocular cues are based on the receipt of sensory information in three dimensions from both eyes and monocular cues can be observed with just one eye. Binocular cues include retinal disparity, which exploits parallax and vergence. Stereopsis is made possible with binocular vision. Monocular cues include relative size (distant objects subtend smaller visual angles than near obj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
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.

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 ...

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 ...

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.

Cynegeticus
''Cynegeticus'' ( grc-gre, Κυνηγετικός, ''Kynegetikos'' "related to hunting" from κυνηγέω "I hunt"), is a treatise by the ancient Greek philosopher and military leader Xenophon, usually translated as "On Hunting" or "Hunting with Dogs." It is one of the four works by Xenophon on arts or skills (each ends with -ikos/-icus). The other three are: '' Hipparchicus'' ("The Skilled Cavalry Commander") '' Peri Hippikes'' ("On Horsemanship"), ''Oeconomicus'' ("On Estate Management"). Synopsis Chapter 1 Xenophon begins discussing the importance of hunting and how the gods Apollo and Artemis bestowed game and hounds upon Chiron the gentle centaur who used hunting to teach twenty-one heroes.

Arrian
Arrian of Nicomedia (; Greek: ''Arrianos''; la, Lucius Flavius Arrianus; ) was a Greek historian, public servant, military commander and philosopher of the Roman period. ''The Anabasis of Alexander'' by Arrian is considered the best source on the campaigns of Alexander the Great. Scholars have generally preferred Arrian to other extant primary sources; though this attitude is beginning to change in light of modern studies into Arrian's method. Arrian's life Arrian was born in Nicomedia (present-day İzmit), the provincial capital of Bithynia. Cassius Dio called him Flavius Arrianus Nicomediensis. In respect of his birth date, sources provide similar dates for his birth; within a few years prior to 90, 89, and 85–90 AD. The line of reasoning for dates belonging to 85–90 AD is from the fact of Arrian being made a consul around 130 AD, and the usual age for this, during this period, being forty-two years of age.
