Greyhound

The Greyhound is a breed of sighthound that has been primarily bred for coursing game and racing, but with recent resurgence of popularity as a pedigree show dog and family pet. It is a gentle and intelligent breed. A combination of long, powerful legs, deep chest, flexible spine and slim build allow it to reach average race speeds of, or in excess of, 18 metres per second (59 feet per second) or 63 km/h.

Appearance
Males are usually 71 to 76 cm tall at the withers and weigh around 27 to 40 kg. Females tend to be smaller with shoulder heights ranging from 68 to 71 cm and weights from less than 27 to 34 kg. Greyhounds have very short hair, which is easy to maintain. There are approximately thirty recognized color forms, of which variations of white, brindle, fawn, black, red and blue (gray) can appear uniquely or in combination.

Anatomy
The key to the speed of a Greyhound can be found in its light but muscular build, largest heart, and highest percentage of fast-twitch muscle of any breed, the double suspension gallop and the extreme flexibility of the spine. "Double suspension rotary gallop" describes the fastest running gait of the Greyhound in which all four feet are free from the ground in two phases, contracted and extended, during each full stride.

Temperament
The Greyhound is not an aggressive dog, as some may believe due to muzzles worn during racing. Muzzles are worn to prevent injuries resulting from dogs nipping one another during - but more likely immediately after a race - when the 'hare' has disappeared out of sight and the dogs are no longer racing but still excited. The thin skin of the Greyhound can tear easily from a small nick from teeth so even a minor skirmish can result in stitches and time out from racing. Greyhounds with a high prey drive occasionally wear muzzles outside the racetrack; owners aware that their Greyhound has a high tendency to chase small prey will protect small prey by applying the muzzle.

Contrary to popular belief, adult Greyhounds do not need extended periods of daily exercise, as they are bred for sprinting rather than endurance. Greyhound puppies that have not been taught how to utilize their energy, however, can be hyperactive and destructive if not given an outlet, and they require more experienced handlers.

Greyhounds as pets
Greyhound owners and adoption groups consider Greyhounds to be wonderful pets.

Greyhounds are quiet, gentle, and loyal to owners. Generally, the Greyhound is not a barker. Occasionally, the dog may bark or 'roo.' They are very loving creatures, and they enjoy the company of their humans and other dogs. Whether a Greyhound enjoys the company of other small animals or cats depends on the individual dog's personality. Greyhounds will typically chase small animals; those lacking a high 'prey drive' will be able to coexist happily with toy dog breeds and/or cats.

Greyhounds live most happily as pets in quiet environments. They do well in families with children as long as the children are taught to properly treat a Greyhound. Greyhounds have a sensitive nature, and gentle commands work best as training methods.

They are pack-oriented dogs, which means that they will quickly adopt humans into their pack as alpha. Greyhounds occasionally develop separation anxiety when re-housed or when their owners have to leave them alone for a period of time. The addition of a second Greyhound often solves this problem.

Greyhounds are generally not barkers, which is beneficial in suburban environments, and they are usually as friendly to strangers as they are with their own family.

A very common misconception regarding Greyhounds is that they are hyperactive. In retired racing Greyhounds, this is usually not the case. Greyhounds can live comfortably as apartment dogs, as they do not require much space and sleep close to 18 hours per day. In fact, due to their calm temperament, Greyhounds can make better "apartment dogs" than smaller, more active breeds.

At some race tracks, Greyhounds are housed in crates for upwards of 20 hours per day, and most know of no other way of life than to remain in a crate the majority of the day. Crate training a retired greyhound in a home is therefore generally extremely easy.

Many Greyhound adoption groups recommend that owners keep their Greyhounds on a leash whenever outdoors, except in fully enclosed areas. This is due to their prey-drive, their speed, and the assertion that Greyhounds have no road sense. However a good run at least once a week is important especially for younger greyhounds and suitable areas can usually be found. Due to their size and strength, adoption groups recommend that fences be between 4 and 6 feet, to prevent them being able to jump.

Two online databases are available to search for all past and present registered purebred Greyhounds: Greyhound-Data.com and Rosnet2000.com Dogs can be searched by their Bertillon number, race name, or other attributes. Data includes photos, race statistics, and pedigree.

Coursing
The original primary use of Greyhounds, both in the British Isles and on the Continent of Europe, was in the coursing of deer. Later, they specialized in competition hare coursing. Some Greyhounds today are still used for coursing, although artificial lure sports like lure coursing and racing are far more common and popular.

However, many breeders of racing Greyhound argue that coursing is still important. This is the case particularly in Ireland, where many of the world’s leading breeders are based. A bloodline that has produced a champion on the live hare coursing field is often crossed with track lines in order to keep the early pace (i.e. speed over first 100 yards) that Greyhounds are renowned for prominent in the line. Many of the leading sprinters over 300 yards to 550 yards have bloodlines able to be traced back through Irish sires within a few generations that won events such as the Irish Coursing Derby or the Irish Cup. The majority of pure-bred Greyhounds are whelped in Ireland. Researching via Greyhound data websites will note coursing champions within a few generations in the pedigree of track racing champions.

Racing
Until the early twentieth century, Greyhounds were principally bred and trained for hunting and coursing. During the 1920s, modern Greyhound racing was introduced into the United States and England (Belle Vue Stadium, Manchester, July 1926), as well as Northern Ireland (Celtic Park (Belfast), April 1927) and the Republic of Ireland (Shelbourne Park, Dublin). The Greyhound holds the record for fastest recorded dog.

Aside from professional racing, many Greyhounds enjoy success on the amateur race track. Organizations like the Large Gazehound Racing Association (LGRA) and the National Oval Track Racing Association (NOTRA) provide opportunities for Greyhounds and other sighthound breeds to compete in amateur racing events all over the United States

Rescue/Adoption
Greyhounds make excellent pets. There is a common misconception that greyhounds require a lot of activity and running. They are actually quite docile, and spend most of their days relaxing on their favorite pillow. Since greyhounds spend most of their pre-adoption lives in a kennel, they are already crate trained. Greyhound rescue is a critical aspect of the career of a racing dog. Retired racers that do not find adoptive homes are usually put down.

Companion
Historically the Greyhound has since its first appearance as a hunting type and breed, enjoyed a specific degree of fame and definition in Western literature heraldry and art, as the most elegant or noble companion and hunter of the canine world. In modern times, the professional racing industry with its large numbers of track bred Greyhounds, as well as the international adoption programs aimed at rescuing and re-homing dogs surplus to the industry, have redefined the breed in their almost mutually dependent pursuit of its welfare, as a sporting dog that will supply friendly companionship in its retirement. Outside the racing industry and coursing community, the Kennel Clubs' registered breed still enjoys a modest following as a show dog and pet. There is an emerging pattern visible in recent years (2009–2010), of a significant decline in track betting and multiple track closures in the US, which will have consequences for the origin of future companion Greyhounds, and the re-homing of current ex-racers.

Health and physiology
Greyhounds are typically a healthy and long-lived breed, and hereditary illness is rare. Some Greyhounds have been known to develop esophageal achalasia, bloat (gastric torsion), and osteosarcoma. Because the Greyhound's lean physique makes it ill-suited to sleeping on hard surfaces, owners of companion Greyhounds generally provide soft bedding; without bedding, Greyhounds are prone to develop painful skin sores. The typical Greyhound lifespan is 10 to 13 years.

Due to the unique physiology and anatomy of Greyhounds, a veterinarian who understands the issues relevant to the breed is generally needed when the dogs need treatment, particularly when anaesthesia is required. Greyhounds cannot metabolize barbiturate-based anesthesia as other breeds can because they have lower amounts of oxidative enzymes in their livers. Greyhounds demonstrate unusual blood chemistry, which can be misread by veterinarians not familiar with the breed; this can result in an incorrect diagnosis.

Greyhounds are very sensitive to insecticides. Many vets do not recommend the use of flea collars or flea spray on Greyhounds unless it is a pyrethrin-based product. (See Dog fleas.) Products like Advantage, Frontline, Lufenuron, and Amitraz are safe for use on Greyhounds and are very effective in controlling fleas and ticks.

Greyhounds have higher levels of red blood cells than other breeds. Since red blood cells carry oxygen to the muscles, this higher level allows the hound to move larger quantities of oxygen faster from the lungs to the muscles. Greyhounds have lower levels of platelets than other breeds. Veterinary blood services often use Greyhounds as universal blood donors.

Greyhounds do not have undercoats and thus are less likely to trigger people's dog allergies (they are sometimes incorrectly referred to as "hypoallergenic"). The lack of an undercoat, coupled with a general lack of body fat, also makes Greyhounds more susceptible to extreme temperatures; because of this, they must be housed inside.

History
The breed's origin is romantically reputed to be connected to Ancient Egypt, where depictions of smooth-coated sighthound types have been found which are typical of saluki (Persian greyhound) or sloughi (tombs at Beni Hassan c. 2000 BC). However, analyses of DNA reported in 2004 suggest that the Greyhound is not closely related to these breeds, but is a close relative to herding dogs. Historical literature on the first sighthound in Europe (Arrian), the vertragus, the probable antecedent of the Greyhound, suggests that the origin is with the ancient Celts from Eastern Europe or Eurasia. All modern, pure-bred pedigree Greyhounds are derived from the Greyhound stock recorded and registered, firstly in the private 18th century, then public 19th century studbooks, which ultimately were registered with coursing, racing, and kennel club authorities of the United Kingdom.

Historically, these sighthounds were used primarily for hunting in the open where their keen eyesight is valuable. It is believed that they (or at least similarly named dogs) were introduced to the area now known as the United Kingdom in the 5th and 6th century BC from Celtic mainland Europe although the Picts and other hunter gatherer tribes of the northern area now known as Scotland were believed to have had large hounds similar to that of the deerhound before the 6th century BC.

The name "Greyhound" is generally believed to come from the Old English grighund. "Hund" is the antecedent of the modern "hound", but the meaning of "grig" is undetermined, other than in reference to dogs in Old English and Old Norse. Its origin does not appear to have any common root with the modern word "grey" for color, and indeed the Greyhound is seen with a wide variety of coat colors. It is known that in England during the medieval period, lords and royalty keen to own Greyhounds for sport, requested they be bred to color variants that made them easier to view and identify in pursuit of their quarry. The lighter colors, patch-like markings and white appeared in the breed that was once ordinarily grey in color. The Greyhound is the only dog mentioned by name in the Bible; many versions, including the King James version, name the Greyhound as one of the "four things stately" in the Proverbs. However, some newer biblical translations, including The New International Version, have changed this to strutting rooster, which appears to be an alternative translation of the Hebrew term mothen zarzir.

According to Pokorny the English name "Greyhound" does not mean "grey dog/hound", but simply "fair dog". Subsequent words have been derived from the Proto-Indo-European root *g'her- "shine, twinkle": English grey, Old High German gris "grey, old", Old Icelandic griss "piglet, pig", Old Icelandic gryja "to dawn", gryjandi "morning twilight", Old Irish grian "sun", Old Church Slavonic zorja "morning twilight, brightness". The common sense of these words is "to shine; bright".

In 1928, the very first winner of Best in Show at Crufts was Primeley Sceptre, a Greyhound owned by H. Whitley.

Greyhound Bus
The Greyhound Bus Lines bus company, in keeping with their logo which sports a racing Greyhound, occasionally airs television commercials starring a talking computer-generated Greyhound. The Greyhound in these commercial shorts is often noted for his dry, deadpan wit. In holiday season commercials, the Greyhound also sings about fare discounts, the song being set to a Christmas carol.
