Sighthounds (also called gazehounds ) are a type of hound dog that hunts primarily by sight and speed, unlike scent hounds , which rely on scent and endurance.
90-477: 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
180-413: 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

All male deer have antlers , with the exception of the water deer , in which males have long tusk-like canines that reach below the lower jaw. Females generally lack antlers, though female reindeer bear antlers smaller and less branched than those of the males. Occasionally females in other species may develop antlers, especially in telemetacarpal deer such as European roe deer, red deer, white-tailed deer and mule deer and less often in plesiometacarpal deer. A study of antlered female white-tailed deer noted that antlers tend to be small and malformed, and are shed frequently around

Next is the Grand Excellent Championship which may be awarded to dogs who accumulate 100 points and have won at least one Best in the show. Region is not a factor in determining points for a win in Canada—the point schedule is the same across the country. In Colombia , dog shows are maintained and organised by the Association Colombian Kennel Club (Asociacion Club Canino Colombiano) . Their conformation shows follow

Antler development begins from the pedicel, a bony structure that appears on the top of the skull by the time the animal is a year old. The pedicel gives rise to a spiky antler the following year, that is replaced by a branched antler in
720-481: A comparison of each dog to a judge's mental image of the ideal breed type as outlined in the individual breed's breed standard . Dog show judges attempt to identify dogs who epitomise the published standards for each breed. Some judgments must be subjective. As an example, what exactly entails a "full coat" or a "cheerful attitude", descriptions found in breed standards, can be learned different. Judges are generally certified to judge one or several breeds, usually in

In New Zealand, deer are thought to be important as vectors picking up M. bovis in areas where brushtail possums Trichosurus vulpecula are infected, and transferring it to previously uninfected possums when their carcasses are scavenged elsewhere. The white-tailed deer Odocoileus virginianus has been confirmed as

Sighthounds such as the Saluki/Sloughi type (both named after the Seleucid Empire ) may have existed for at least 5,000 years, with the earliest presumed sighthound remains of a male with a shoulder height around 54 cm, compared to
990-429: 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 and some of which may be unique to one breed. The typical sighthound type has

Wolves and other wild dogs are dolichocephalic or mesaticephalic , but some domestic dogs have become brachycephalic (short-headed) due to artificial selection by humans over the course of 12,000 years. Dolichocephalic dogs have a wider field of vision but smaller overlap between
1170-555: A nearly complete skeleton of Diacodexis discovered in 1982 gave rise to speculation that this ancestor could be closer to the non-ruminants than the ruminants. Andromeryx is another prominent prehistoric ruminant, but appears to be closer to the tragulids . The formation of the Himalayas and the Alps brought about significant geographic changes. This was the chief reason behind the extensive diversification of deer-like forms and
1260-543: A result of acclimatisation society releases in the 19th century, Australia has six introduced species of deer that have established sustainable wild populations. They are fallow deer, red deer, sambar, hog deer, rusa , and chital. Red deer were introduced into New Zealand in 1851 from English and Scottish stock. Many have been domesticated in deer farms since the late 1960s and are common farm animals there now. Seven other species of deer were introduced into New Zealand but none are as widespread as red deer. Deer constitute
1350-490: A smaller form, but a combination of anthropogenic and climatic pressures is now thought to be the most likely culprit. Meanwhile, the moose and reindeer radiated into North America from Siberia. Deer constitute the artiodactyl family Cervidae. This family was first described by German zoologist Georg August Goldfuss in Handbuch der Zoologie (1820). Three subfamilies were recognised: Capreolinae (first described by
1440-783: A wide variety of vegetation. The teeth of deer are adapted to feeding on vegetation, and like other ruminants, they lack upper incisors , instead having a tough pad at the front of their upper jaw. Deer are browsers , and feed primarily on foliage of grasses , sedges , forbs , shrubs and trees , secondarily on lichens in northern latitudes during winter. They have small, unspecialized stomachs by ruminant standards, and high nutrition requirements. Rather than eating and digesting vast quantities of low-grade fibrous food as, for example, sheep and cattle do, deer select easily digestible shoots, young leaves, fresh grasses, soft twigs, fruit, fungi , and lichens . The low-fibered food, after minimal fermentation and shredding, passes rapidly through
1530-499: A wild animal of any kind. Cognates of Old English dēor in other dead Germanic languages have the general sense of animal , such as Old High German tior , Old Norse djur or dȳr , Gothic dius , Old Saxon dier , and Old Frisian diar . This general sense gave way to the modern English sense by the end of the Middle English period, around 1500. All modern Germanic languages save English and Scots retain

While often associated with forests, many deer are ecotone species that live in transitional areas between forests and thickets (for cover) and prairie and savanna (open space). The majority of large deer species inhabit temperate mixed deciduous forest, mountain mixed coniferous forest, tropical seasonal/dry forest, and savanna habitats around
1800-602: 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. A conformation dog show is not a comparison of one dog to another but
1890-452: Is only slightly taller and heavier. Sexual dimorphism is quite pronounced – in most species males tend to be larger than females, and, except for the reindeer, only males have antlers. Coat colour generally varies between red and brown, though it can be as dark as chocolate brown in the tufted deer or have a grayish tinge as in elk. Different species of brocket deer vary from gray to reddish brown in coat colour. Several species such as

A male usually leaves and never sees his mother again, but females sometimes come back with their own fawns and form small herds. In some areas of the UK, deer (especially fallow deer due to their gregarious behaviour ) have been implicated as a possible reservoir for transmission of bovine tuberculosis ,

The elk stands 1.4–2 metres (4 ft 7 in – 6 ft 7 in) at the shoulder and weighs 240–450 kilograms (530–990 lb). The northern pudu is the smallest deer in the world; it reaches merely 32–35 centimetres ( 12 + 1 ⁄ 2 –14 in) at the shoulder and weighs 3.3–6 kilograms ( 7 + 1 ⁄ 4 – 13 + 1 ⁄ 4 lb). The southern pudu

In August 2008, BBC1 televised a documentary film titled Pedigree Dogs Exposed , which investigated the subject of health issues affecting pedigree dogs in the United Kingdom, with a particular emphasis on dogs bred for showing. The programme provoked criticisms of kennel clubs. Following

Another extinct species of deer, Megaceroides algericus , was present in North Africa until 6000 years ago. Fallow deer have been introduced to South Africa . Small species of brocket deer and pudús of Central and South America , and muntjacs of Asia generally occupy dense forests and are less often seen in open spaces, with

The tribes Capreolini and Rangiferini appeared around 4–7 Mya. Around 5 Mya, the rangiferina † Bretzia and † Eocoileus were the first cervids to reach North America. This implies the Bering Strait could be crossed during
2610-957: The Sami people of Finland and Scandinavia, the Tungusic peoples, Mongolians, and Turkic peoples of Southern Siberia, Northern Mongolia, and the Ussuri Region have also taken to raising semi-domesticated herds of Asian caribou. The highest concentration of large deer species in the tropics occurs in Southern Asia in India's Indo-Gangetic Plain Region and Nepal 's Terai Region. These fertile plains consist of tropical seasonal moist deciduous, dry deciduous forests, and both dry and wet savannas that are home to chital , hog deer , barasingha , Indian sambar , and Indian muntjac . Grazing species such as
2700-532: The Tethys Ocean disappeared to give way to vast stretches of grassland; these provided the deer with abundant protein-rich vegetation that led to the development of ornamental antlers and allowed populations to flourish and colonise areas. As antlers had become pronounced, the canines were either lost or became poorly represented (as in elk), probably because diet was no longer browse -dominated and antlers were better display organs. In muntjac and tufted deer,

Cervidae is divided into subfamilies Cervinae (which includes, among others, muntjac , elk (wapiti), red deer , and fallow deer ) and Capreolinae (which includes, among others reindeer (caribou), white-tailed deer , roe deer , and moose ). Male deer of almost all species (except the water deer ), as well as female reindeer, grow and shed new antlers each year. These antlers are bony extensions of

The tribe Muntiacini made its appearance as † Muntiacus leilaoensis around 7–8 Mya; The early muntjacs varied in size–as small as hares or as large as fallow deer. They had tusks for fighting and antlers for defence. Capreolinae followed soon after; Alceini appeared 6.4–8.4 Mya. Around this period,

Some deer, such as those on the island of Rùm , do consume meat when it is available. Nearly all deer have a facial gland in front of each eye. The gland contains a strongly scented pheromone , used to mark its home range. Bucks of a wide range of species open these glands wide when angry or excited. All deer have

Mountain slope habitats vary from moist coniferous/mixed forested habitats to dry subalpine/pine forests with alpine meadows higher up. The foothills and river valleys between the mountain ranges provide a mosaic of cropland and deciduous parklands. The rare woodland caribou have
3330-511: The Cervidae, are believed to have evolved from Diacodexis , the earliest known artiodactyl (even-toed ungulate), 50–55 Mya in the Eocene. Diacodexis , nearly the size of a rabbit , featured the talus bone characteristic of all modern even-toed ungulates . This ancestor and its relatives occurred throughout North America and Eurasia, but were on the decline by at least 46 Mya. Analysis of

Population genomic analysis proposes that true sighthounds originated independently from native dogs and were comprehensively admixed among breeds, supporting the multiple origins hypothesis of sighthounds. Although today most sighthounds are kept primarily as pets , some of them may have been bred for as many as thousands of years to detect movement of prey, then chase, capture, and kill it primarily by speed. They thrive on physical activity. Some have mellow personalities, others are watchful or even hostile towards strangers, but

The Anglo-Irish naturalist Victor Brooke suggested in 1878 that deer could be bifurcated into two classes on the according to
3600-773: The European Dremotherium ; these sabre-toothed animals are believed to have been the direct ancestors of all modern antlered deer, though they themselves lacked antlers. Another contemporaneous form was the four-horned protoceratid Protoceras , that was replaced by Syndyoceras in the Miocene; these animals were unique in having a horn on the nose. Late Eocene fossils dated approximately 35 million years ago, which were found in North America, show that Syndyoceras had bony skull outgrowths that resembled non-deciduous antlers. Fossil evidence suggests that

Present-day fallow deer populations in Europe are a result of historic man-made introductions of this species, first to the Mediterranean regions of Europe, then eventually to the rest of Europe. They were initially park animals that later escaped and reestablished themselves in the wild. Historically, Europe's deer species shared their deciduous forest habitat with other herbivores, such as

Many national parks and protected reserves in Europe have populations of red deer, roe deer , and fallow deer. These species have long been associated with the continent of Europe, but also inhabit Asia Minor , the Caucasus Mountains , and Northwestern Iran . "European" fallow deer historically lived over much of Europe during

Asian caribou occupy the northern fringes of this region along the Sino-Russian border. Deer such as the sika deer, Thorold's deer , Central Asian red deer , and elk have historically been farmed for their antlers by Han Chinese , Turkic peoples , Tungusic peoples , Mongolians , and Koreans . Like
3960-407: The alimentary canal. The deer require a large amount of minerals such as calcium and phosphate in order to support antler growth, and this further necessitates a nutrient-rich diet. There are some reports of deer engaging in carnivorous activity, such as eating dead alewives along lakeshores or depredating the nests of northern bobwhites . Nearly all cervids are so-called uniparental species:
4050-618: The antlers as well as the canines are small. The tragulids have long canines to this day. With the onset of the Pliocene , the global climate became cooler. A fall in the sea-level led to massive glaciation; consequently, grasslands abounded in nutritious forage. Thus a new spurt in deer populations ensued. The oldest member of Cervini, † Cervocerus novorossiae , appeared around the transition from Miocene to Pliocene (4.2–6 Mya) in Eurasia; cervine fossils from early Pliocene to as late as
4140-875: The antlers create grooves that allow another male's antlers to lock into place. This allows the males to wrestle without risking injury to the face. Antlers are correlated to an individual's position in the social hierarchy and its behaviour. For instance, the heavier the antlers, the higher the individual's status in the social hierarchy, and the greater the delay in shedding the antlers; males with larger antlers tend to be more aggressive and dominant over others. Antlers can be an honest signal of genetic quality; males with larger antlers relative to body size tend to have increased resistance to pathogens and higher reproductive capacity. In elk in Yellowstone National Park , antlers also provide protection against predation by wolves . Homology of tines, that is,
4230-503: The basis of diploid number of chromosomes in the late 20th century has been flawed by several inconsistencies. In 1987, the zoologists Colin Groves and Peter Grubb identified three subfamilies: Cervinae, Hydropotinae and Odocoileinae; they noted that the hydropotines lack antlers, and the other two subfamilies differ in their skeletal morphology. They reverted from this classification in 2000. Molecular phylogenetic analyses since
4320-692: The branching structure of antlers among species, have been discussed before the 1900s. Recently, a new method to describe the branching structure of antlers and determining homology of tines was developed. Most deer bear 32 teeth; the corresponding dental formula is: 0.0.3.3 3.1.3.3 . The elk and the reindeer may be exceptions, as they may retain their upper canines and thus have 34 teeth (dental formula: 0.1.3.3 3.1.3.3 ). The Chinese water deer, tufted deer, and muntjac have enlarged upper canine teeth forming sharp tusks, while other species often lack upper canines altogether. The cheek teeth of deer have crescent ridges of enamel, which enable them to grind

They stated that they will impose a ban on breeding between dogs that are closely related and will impose greater monitoring to prevent unhealthy dogs from being entered. A bench show
4500-405: The chital, the fallow deer and the sika deer feature white spots on a brown coat. Coat of reindeer shows notable geographical variation. Deer undergo two moults in a year; for instance, in red deer the red, thin-haired summer coat is gradually replaced by the dense, greyish brown winter coat in autumn, which in turn gives way to the summer coat in the following spring. Moulting is affected by

Dicrocerus featured single-forked antlers that were shed regularly. Stephanocemas had more developed and diffuse ("crowned") antlers. Procervulus ( Palaeomerycidae ) also had antlers that were not shed. Contemporary forms such as

Eventually, with the development of antlers, the tusks as well as the upper incisors disappeared. Thus, evolution of deer took nearly 30 million years. Biologist Valerius Geist suggests evolution to have occurred in stages. There are not many prominent fossils to trace this evolution, but only fragments of skeletons and antlers that might be easily confused with false antlers of non-cervid species.

The early Pleistocene cervid † Eucladoceros was comparable in size to the modern elk. † Megaloceros (Pliocene–Pleistocene) featured the Irish elk ( M. giganteus ), one of the largest known cervids . The Irish elk reached 2 metres ( 6 + 1 ⁄ 2 ft) at the shoulder and had heavy antlers that spanned 3.6 metres (11 ft 10 in) from tip to tip. These large animals were traditionally thought to have faced extinction due to conflict between sexual selection for large antlers and body and natural selection for

Apart from coursing and hunting , various dog sports are practiced with purebred sighthounds, and sometimes with lurchers and longdogs . Such sports include racing , lure coursing , and other events. A number of breeds or types of dogs which do not hunt solely by speed and sight, as well as a number of non-hunting breeds, are currently being recognized as sighthounds, either formally or informally by kennel clubs, or lure and live coursing clubs. These include: When competing in conformation shows , most Anglophone kennel clubs , including

For many types of deer in modern English usage, the male is a buck and the female a doe , but the terms vary with dialect, and according to the size of the species. The male red deer is a stag , while for other large species the male is a bull , the female a cow , as in cattle. In older usage,
6300-413: The most restricted range living at higher altitudes in the subalpine meadows and alpine tundra areas of some of the mountain ranges. Elk and mule deer both migrate between the alpine meadows and lower coniferous forests and tend to be most common in this region. Elk also inhabit river valley bottomlands, which they share with White-tailed deer. The White-tailed deer have recently expanded their range within
6390-444: The number of dogs competing and the area where the show is held. At least two wins must be a set of three or more points ("majors") under two different judges; at least one additional win under a third judge is also required. The rules for the United Kennel Club (UKC) use a different points system. A championship requires a combination of points and competition wins. Points are awarded at breed level for each win; for example, winning
6480-540: The others are optional. In some cases, one or more of these classes may be divided by color, height, weight, or coat type. A dog can earn extra points during these awards, depending on the number of dogs of its sex and the Champions that were competing against it. In the American Kennel Club, a dog needs 15 points to become a Champion, with each win gaining anywhere from zero to five points depending on
6570-649: The possible exception of the Indian muntjac . There are also several species of deer that are highly specialized and live almost exclusively in mountains, grasslands, swamps, and "wet" savannas, or riparian corridors surrounded by deserts . Some deer have a circumpolar distribution in both North America and Eurasia . Examples include the caribou that live in Arctic tundra and taiga (boreal forests) and moose that inhabit taiga and adjacent areas. Huemul deer ( taruca and Chilean huemul ) of South America 's Andes fill
6660-402: The right spot and never really find it." Deer appear to be immune to this parasite; it passes through the digestive system and is excreted in the feces. The parasite is not screened by the moose intestine, and passes into the brain where damage is done that is externally apparent, both in behaviour and in gait. Deer, elk and moose in North America may suffer from chronic wasting disease , which
6750-658: The rules of the International Federation of Kennel Clubs. ( Fédération Cynologique Internationale ) . According to the ACCC, only purebred dogs recognised by the FCI are allowed to participate. Purebreds of Colombian origin must be registered with the ACCC, and therefore they must hold an LOC number (Number in the Colombian Book of Origins). In the United Kingdom, the international championship show Crufts
6840-638: The same group , but a few "all-breed" judges can judge a large number of breeds. Dogs compete at dog shows to earn points or certification towards championship titles. The Kennel Club (UK) system, which is also used by the Australian National Kennel Council and in other countries, is considered the most difficult to earn a title under. Fédération Cynologique Internationale sponsors international shows that differ from other shows in that dogs first receive individual written descriptions of positive and negative qualities from
6930-417: The second most diverse family of artiodactyla after bovids. Though of a similar build, deer are strongly distinguished from antelopes by their antlers , which are temporary and regularly regrown unlike the permanent horns of bovids. Characteristics typical of deer include long, powerful legs, a diminutive tail and long ears. Deer exhibit a broad variation in physical proportions. The largest extant deer
7020-467: The selection of breeding dogs based solely upon appearance, which is seen by some as detrimental to working qualities and, at worst, as a promotion of eugenics . The shows have been criticized for encouraging breeding of traits that are harmful to the dogs; for example, the Pekingese dog who won at Britain's most prestigious dog show in 2003 had to be photographed while lying on an icepack after winning
7110-661: The show because the dog could not breathe well enough to efficiently cool his own overheated body. Breeding selective traits reduces genetic diversity , which can create some health problems in dogs. In the United States, some working dog breed organisations, such as the American Border Collie Association and the Jack Russell Terrier Club of America , have tried to fight to keep their breeds from being recognised by
7200-501: The skull and are often used for combat between males. The musk deer ( Moschidae ) of Asia and chevrotains ( Tragulidae ) of tropical African and Asian forests are separate families that are also in the ruminant clade Ruminantia ; they are not especially closely related to Cervidae. Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology , religion, and literature throughout history, as well as in heraldry , such as red deer that appear in
7290-524: The sole maintenance host in the Michigan outbreak of bovine tuberculosis which remains a significant barrier to the US nationwide eradication of the disease in livestock. Moose and deer can carry rabies . Docile moose may suffer from brain worm , a helminth which drills holes through the brain in its search for a suitable place to lay its eggs. A government biologist states that "They move around looking for
7380-574: The third year. This process of losing a set of antlers to develop a larger and more branched set continues for the rest of the life. The antlers emerge as soft tissues (known as velvet antlers ) and progressively harden into bony structures (known as hard antlers), following mineralisation and blockage of blood vessels in the tissue, from the tip to the base. Antlers might be one of the most exaggerated male secondary sexual characteristics , and are intended primarily for reproductive success through sexual selection and for combat. The tines (forks) on
7470-541: The time of parturition. The fallow deer and the various subspecies of the reindeer have the largest as well as the heaviest antlers, both in absolute terms as well as in proportion to body mass (an average of eight grams per kilogram of body mass); the tufted deer, on the other hand, has the smallest antlers of all deer, while the pudú has the lightest antlers with respect to body mass (0.6 g per kilogram of body mass). The structure of antlers show considerable variation; while fallow deer and elk antlers are palmate (with
7560-456: The various Asian rhinoceros species, various antelope species (such as nilgai , four-horned antelope , blackbuck , and Indian gazelle in India), and wild oxen (such as wild Asian water buffalo , gaur , banteng , and kouprey ). One way that different herbivores can survive together in a given area is for each species to have different food preferences, although there may be some overlap. As
7650-512: The world. Clearing open areas within forests to some extent may actually benefit deer populations by exposing the understory and allowing the types of grasses, weeds, and herbs to grow that deer like to eat. Access to adjacent croplands may also benefit deer. Adequate forest or brush cover must still be provided for populations to grow and thrive. Deer are widely distributed, with indigenous representatives in all continents except Antarctica and Australia , though Africa has only one native deer,
7740-547: The young, known in most species as fawns, are only cared for by the mother, most often called a doe. A doe generally has one or two fawns at a time (triplets, while not unknown, are uncommon). Mating season typically begins in later August and lasts until December. Some species mate until early March. The gestation period is anywhere up to ten months for the European roe deer. Most fawns are born with their fur covered with white spots, though in many species they lose these spots by
7830-524: Was first held in 1891. Since its centenary year in 1991, the show has officially been recognised as the world's largest and most prestigious dog show by Guinness World Records , with a total of 22,991 dogs being exhibited that year. 22,964 dogs were exhibited in 2008, 27 short of the previous record. The World Dog Show is sponsored by the Fédération Cynologique Internationale for international championships in conformation and other dog sports . The location rotates between member countries. The 2008 show

The Westminster Kennel Club Dog Show is an all-breed conformation show, historically held in the New York City area. It is one of a handful of benched shows in the United States. It is often compared to the World Dog Show ; the World Dog Show is considered a bit more valuable reputation-wise. Some critics state that conformation shows lead to
8010-513: Was identified at a Colorado laboratory in the 1960s and is believed to be a prion disease. Out of an abundance of caution hunters are advised to avoid contact with specified risk material (SRM) such as the brain, spinal column or lymph nodes. Deboning the meat when butchering and sanitizing the knives and other tools used to butcher are amongst other government recommendations. Deer are believed to have evolved from antlerless, tusked ancestors that resembled modern duikers and diminutive deer in
8100-474: Was once primarily tropical seasonal moist deciduous forest and wet savanna that hosted populations of hog deer, the now-extinct Schomburgk's deer , Eld's deer , Indian sambar, and Indian muntjac. Both the hog deer and Eld's deer are rare, whereas Indian sambar and Indian muntjac thrive in protected national parks, such as Khao Yai . Many of these South Asian and Southeast Asian deer species also share their habitat with other herbivores , such as Asian elephants ,
