Golden Retriever


The Golden Retriever is a medium-sized breed of dog. They were historically developed as gundogs to retrieve shot waterfowl such as ducks and upland game birds during hunting and shooting parties. As such, they were bred to have a soft mouth to retrieve game undamaged and have an instinctive love of water. The golden retriever has a dense inner coat that provides it with adequate warmth. The outer coat is sleek and water repellent, and lies flat against the body. The official colour of the breed is the varying shades of gold that are most often seen. These dogs are well suited to suburban or country environments. They need lots of outdoor exercise but should be kept fenced in because of their instincts as hunting dogs.
The breed's intelligence and versatility suit the dogs well for a variety of roles including guide dog for the blind, hearing dog for deaf people, hunting dog, illegal drug detector, and search and rescue participant. Because of their loyal and gentle temperament, golden retrievers are also popular family pets.
Golden Retrievers possess a friendly, eager-to-please demeanour, and are the fifth most popular family dog breed (by registration) in the United States, the fifth most popular in Australia, and the eighth most popular in the United Kingdom. 

History
Golden Retrievers were bred to retrieve
The Golden Retriever has its roots in Scotland. In the mid eighteenth century, wildfowl hunting was very popular among the rich. Scotland was covered with ponds and rivers, so a dog was needed that could retrieve from water as well as land. So, early retrievers were crossed with the best of water spaniels giving birth to the dog we know as the Golden Retriever The Golden Retriever was first developed in Scotland at "Guisachan" near Glen Affric, the highland estate of Sir Dudley Marjoribanks later Baron Tweedmouth. For many years, there was controversy over which breeds were originally crossed. In 1952, the publication of Marjoribanks' breeding records from 1835 to 1890 dispelled the myth concerning the purchase of a whole troupe of Russian sheepdogs from a visiting circus.
Improvements in guns during the 1800s resulted in more fowl being downed during hunts at greater distances and over increasingly difficult terrain. This led to more birds being lost in the field. Because of this improvement in firearms, a need for a specialist retriever arose as training setter and pointer breeds in retrieval was found to be ineffective. Thus work began on the breeding of the dog to fill this much needed role.
The original cross was of a yellow-coloured Retriever, Nous, with a Tweed Water Spaniel female dog, Belle. The Tweed Water Spaniel is now extinct but was then common in the border country. Marjoribanks had purchased Nous in 1865 from an unregistered litter of otherwise black wavy-coated retriever pups. In 1868, this cross produced a litter that included four pups; these four became the basis of a breeding program which included the Irish Setter, the sandy-coloured Bloodhound, the St. John's Water Dog of Newfoundland, and two more wavy-coated black Retrievers. The bloodline was also inbred and selected for trueness to Marjoribanks' idea of the ultimate hunting dog. His vision included a more vigorous and powerful dog than previous retrievers, one that would still be gentle and trainable. Russian sheepdogs are not mentioned in these records, nor are any other working dog breeds. The ancestry of the Golden Retriever is all sporting dogs, in line with Marjoribanks' goals. The Golden Retriever was active and powerful and had a gentle mouth for retrieving game on hunts.
Golden Retrievers were first accepted for registration by The Kennel Club of England in 1903, as Flat Coats – Golden. They were first exhibited in 1908, and in 1911 were recognised as a breed described as Retriever (Golden and Yellow). In 1913, the Golden Retriever Club was founded. The breed name was officially changed to Golden Retriever in 1920
The Honourable Archie Marjoribanks took a Golden Retriever to Canada in 1881, and registered Lady with the American Kennel Club (AKC) in 1894. These are the first records of the breed in these two countries. The breed was first registered in Canada in 1927, and the Golden Retriever Club of Ontario, now the Golden Retriever Club of Canada, was formed in 1958. The co-founders of the GRCC were Cliff Drysdale, an Englishman who had brought over an English Golden and Jutta Baker, daughter in law of Louis Baker who owned Northland Kennels, possibly Canada's first kennel dedicated to Goldens. The AKC recognised the breed in 1925, and in 1938 the Golden Retriever Club of America was formed.
There are also organisations other than clubs dedicated to golden retrievers, such as breed specific adoption sites.
In July 2006, The Golden Retriever Club of Scotland organised a gathering of Golden Retriever enthusiasts at the ancestral home of Guisachan House. A photograph was taken by photographer Lynn Kipps to commemorate the occasion. It captures 188 Golden Retrievers and therefore holds the record for most Golden Retrievers captured in one image.

Appearance
British type
British-type Golden Retriever
Some variations do exist between the British type Golden Retrievers prevalent throughout Europe and Australia, and those of American lines and these differences are reflected in the breed standard. The muzzle of the British type of dog is wider and shorter, and its forehead is blockier. It has shorter legs, with a slightly deeper chest, and shorter tail. Its features make it generally heavier than the American type. Males should be between 56–61 cm (22–24 inches) at the withers and females slightly shorter at between 51–56 cm (20–22 inches). Their weight, however, is not specified in the UK standard. The KC standard calls for a level topline and straight hindquarters without the slight rear angulation found in American lines. The eyes of the European type are noted for their roundness and darkness as contrasted with the triangular or slanted composition of their American counterparts. A Golden Retriever of British breeding can have a coat colour of any shade of gold or cream; however, red or mahogany are not permissible colours. Originally cream was not an acceptable colour in the UK standard; however, by 1936 the standard was revised to include cream. It was felt this exclusion was a mistake as the original "yellow" retrievers of the 19th century were lighter in colour than the then current standard permitted. As with American lines, white is an unacceptable colour in the show ring. The British KC standard is used in all countries with the exceptions of the USA and Canada. Some breeders of this type in America may import their dogs to improve the temperament and health noted in those bloodlines . Golden Retrievers have a muscular body with great endurance built for hunting.

American type
American Golden Retriever
An American Golden is lankier and less stocky than a British Type. A male should stand 22–24 inches (56–61 cm) in height at the shoulders, and females should be 20–22 inches (51–56 cm). The coat is dense and water repellent, in various shades of lustrous gold, with moderate feathering. The gait should be free, smooth, powerful, and well-coordinated. 

Canadian type
As with American Golden Retrievers, Canadians are often taller and leaner than their British counterparts. However, Canadian retrievers differ in the density and colour of their coats, which are commonly thinner and darker than those of Americans.

Coat and colour
Golden Retrievers vary widely in colour.
As indicated by their name, their coat comes in light golden colours to dark golden colours. They have two different types of hair on their coat. The topcoat is water-resistant and slightly wavy. It sheds in small amounts throughout the year. The undercoat is soft and keeps the retriever cool in summer and warm in winter. The undercoat sheds in the spring and fall. It usually lies flat against the belly. Golden Retrievers have mild feathering on the back of their forelegs and heaver feathering on the front of their neck, back of their thighs and the bottom of their tails. The American Kennel Club (AKC) standard states that the coat is a "rich, lustrous golden of various shades", disallowing coats that are extremely light or extremely dark. This leaves the outer ranges of coat colour up to a judge's discretion when competing in conformation shows. Therefore, "pure white" and "red" are unacceptable colours like black . The Kennel Club (UK) also permits cream as an acceptable coat colour. Judges may also disallow Goldens with pink noses, or those lacking pigment. The Golden's coat can also be of a mahogany colour, referred to as "redheads", although this is not accepted in the British show ring. As a Golden grows older, its coat can become darker or lighter, along with a noticeable whitening of the fur on and around the muzzle. Puppy coats are usually much lighter than their adult coats, but a puppy with a darker colouration at the tips of the ears may indicate a darker adult colour. A golden's coat should never be too long, as this may prove to be a disservice to them in the field, especially when retrieving game. 

Temperament

The temperament of the Golden Retriever is a hallmark of the breed and is described in the standard as "kindly, friendly and confident". Golden Retrievers are great family pets and get along great with children. They are not "one man dogs" and are generally equally amiable with both strangers and those familiar to them. Their trusting, gentle disposition therefore makes them a poor guard dog. Any form of unprovoked aggression or hostility towards either people, dogs or other animals, whether in the show ring or community, is completely unacceptable in a Golden Retriever and is not in keeping with the character of the breed and as such is considered a serious fault. Nor should a Golden Retriever be unduly timid or nervous. The typical Golden Retriever is calm, naturally intelligent and biddable, with an exceptional eagerness to please.

Most Goldens are high energy and need plenty of exercise, such as dog agility.

Golden Retrievers are also noted for their intelligence, it ranks fourth in Stanley Coren's The Intelligence of Dogs following the Border Collie, Poodle, and German Shepherd Dog, being one of the brightest dogs ranked by obedience command trainability. These dogs are also renowned for their patience with children.
By the time they reach maturity however, Goldens will have become active and fun-loving animals with the exceptionally patient demeanour befitting a dog bred to sit quietly for hours in a hunting blind. Adult Golden Retrievers love to work, and have a keen ability to focus on a given task. They will seemingly work until they collapse, so care should be taken to avoid overworking them.
Other characteristics related to their hunting heritage are a size suited for scrambling in and out of boats and an inordinate love for water. Golden Retrievers are exceptionally trainable—due to their intelligence, athleticism and desire to please their handlers—and generally excel in obedience trials. They are also very competitive in agility and other performance events. Harsh training methods are unnecessary as Golden Retrievers often respond very well to positive and upbeat training styles.
Golden Retrievers are compatible with children and adults and are good with other dogs, cats and most livestock. Golden Retrievers are particularly valued for their high level of sociability towards people, calmness, and willingness to learn. Because of this, they are commonly used as guide dogs, mobility assistance dogs, and search and rescue dogs. They are friendly and tend to learn tricks easily.
They are also known to become excellent surrogate mothers to different species. Kittens and even tiger cubs from zoos are well taken care of by golden retrievers. In some cases, a retriever may produce milk for her adopted even though she may not have been pregnant or nursing recently.

Health

The average life span for a Golden Retriever is 11 to 11½ years. Golden Retrievers are susceptible to specific ailments. A responsible breeder will proactively minimise the risk of illness by having the health of dogs in breeding pairs professionally assessed and selected on the basis of complementary traits. They should be taken to the vet for yearly checkups.
Golden retrievers are known to have genetic disorders and other diseases. Hip dysplasia is common in the breed; when buying a puppy, the pedigree should be known and be examined by the OFA or by PennHIP for hip disease. Obesity is also common in the breed because Golden Retrievers love to eat. Puppies should eat about 3 cups of food a day and adults 3-5 cups. This depends on the food and how active the dog is.

Labrador Retriever


   The Labrador Retriever (also Labrador, or Lab for short) is one of several kinds of retriever, a type of gun dog. A breed characteristic is webbed paws for swimming, useful for the breed's original purpose of retrieving fishing nets. The Labrador is the most popular breed of dog by registered ownership in Canada, the United Kingdom, and the United States (since 1991). It is also one of the most popular assistance dog breeds in Australia, Canada, the United Kingdom and the United States and many other countries, as well as being widely used by police and other official bodies for their detection and working abilities. Typically, Labradors are athletic and love to swim, play catch and retrieve games, are good with young children, elderly, and for protection.

History
Nell – A St. John's Water Dog circa 1856
The modern Labrador's ancestors originated on the island of Newfoundland, now part of the province of Newfoundland and Labrador, Canada. The founding breed of the Labrador was the St. John's Water Dog, a breed that emerged through ad-hoc breedings by early settlers of the island in the 16th century. The forebears of the St. John's Dog are not known, but were likely a random-bred mix of English, Irish, and Portuguese working breeds. The Newfoundland (known then as the Greater Newfoundland) is likely a result of the St. John's Dog breeding with mastiffs brought to the island by the generations of Portuguese fishermen who had been fishing offshore since the 16th century. The smaller short-coated St. John's Dog (also known then as the Lesser Newfoundland) was used for retrieval and pulling in nets from the water. These smaller dogs were the forebears of the Labrador Retriever. The white chest, feet, chin, and muzzle - known as tuxedo markings - characteristic of the St. John's Dog often appear in modern Lab mixes, and will occasionally manifest in Labradors as a small white spot on the chest (known as a medallion) or stray white hairs on the feet or muzzle.
The St. John's area of Newfoundland was settled mainly by the English and Irish. Local fishermen originally used the St. John's dog to assist in carrying ropes between boats, towing dories, and helping to retrieve fishnets in the water. The Labrador's loyalty and hard working behaviour were valuable assets for fishermen.
A number of St. John's Dogs were brought back to the Poole area of England in the early 19th century, then the hub of the Newfoundland fishing trade, by the gentry, and became prized as sporting and waterfowl hunting dogs. A few kennels breeding these grew up in England; at the same time a combination of sheep protection policy (Newfoundland) and rabies quarantine (England) led to their gradual demise in their country of origin.

A surviving picture of Buccleuch Avon (b.1885), a foundational dog of many modern Labrador lineages.
The first and second Earls of Malmesbury, who bred for duck shooting on his estate, and the 5th and 6th Dukes of Buccleuch, and youngest son Lord George William Montagu-Douglas-Scott, were instrumental in developing and establishing the modern Labrador breed in 19th century England. The dogs Avon ("Buccleuch Avon") and Ned given by Malmesbury to assist the Duke of Buccleuch's breeding program in the 1880s are considered the ancestors of modern Labradors.
The first St. John's dog was said to be brought to England around 1820; however, the breed's reputation had spread to England long before. There is a story that the Earl of Malmesbury saw a St. John's Dog on a fishing boat and immediately made arrangements with traders to have some of these dogs exported to England. These ancestors of the first labradors so impressed the Earl with their skill and ability for retrieving anything within the water and on shore that he devoted his entire kennel to developing and stabilising the breed.

Early descriptions
Several early descriptions of the St. John's Water Dog exist. In 1822, explorer W.E. Cormack crossed the island of Newfoundland by foot. In his journal he wrote "The dogs are admirably trained as retrievers in fowling, and are otherwise useful.....The smooth or short haired dog is preferred because in frosty weather the long haired kind become encumbered with ice on coming out of the water."
Another early report by a Colonel Hawker described the dog as "by far the best for any kind of shooting. He is generally black and no bigger than a Pointer, very fine in legs, with short, smooth hair and does not carry his tail so much curled as the other; is extremely quick, running, swimming and fighting....and their sense of smell is hardly to be credited...."
In his book Excursions In and About Newfoundland During the Years 1839 and 1840, the geologist Joseph Beete Jukes describes the St. John's Water Dog. "A thin, short-haired, black dog came off-shore to us to-day. The animal was of a breed very different from what we understand by the term Newfoundland dog in England. He had a thin, tapering snout, a long thin tail, and rather thin, but powerful legs, with a lank body, – the hair short and smooth." wrote Jukes. "These are the most abundant dogs in the country...They are no means handsome, but are generally more intelligent and useful than the others...I observed he once or twice put his foot in the water and paddled it about. This foot was white, and Harvey said he did it to "toil" or entice the fish. The whole proceeding struck me as remarkable, more especially as they said he had never been taught anything of the kind."

Name
The foundational breed of what is now the Labrador Retriever was known as the St. John's Water Dog, St. John's Dog, or Lesser Newfoundland. When the dogs were later brought to England, they were named after the geographic area known as "the Labrador" or simply Labrador to distinguish them from the larger Newfoundland breed, even though the breed was from the more southern Avalon Peninsula.

Historical landmarks
The first written reference to the breed was in 1814 ("Instructions to Young Sportsmen" by Colonel Peter Hawker), the first painting in 1823 ("Cora. A Labrador Bitch" by Edwin Landseer), and the first photograph in 1856 (the Earl of Home's dog "Nell", described both as a Labrador and a St. Johns dog). By 1870 the name Labrador Retriever became common in England. The first yellow Labrador on record was born in 1899 (Ben of Hyde, kennels of Major C.J. Radclyffe), and the breed was recognised by The Kennel Club in 1903. The first American Kennel Club (AKC) registration was in 1917. The chocolate Labrador emerged in the 1930s, although liver spotted pups were documented being born at the Buccleuch kennels in 1892. The St. John's dog survived until the early 1980s, the last two individuals being photographed in old age around 1981.

History of subtypes
Yellow and chocolate pups, would occasionally appear (although often culled), until finally gaining acceptance in the 20th century.
The first recognised yellow Labrador was Ben of Hyde, born 1899, and chocolate Labradors became more established in the 1930s.

Yellow (and related shades)
In the early years of the breed through to the mid-20th century, Labradors of a shade we would now call "yellow" were in fact a dark, almost butterscotch, colour (visible in early yellow Labrador photographs). The shade was known as "Golden" until required to be changed by the UK Kennel Club, on the grounds that "Gold" was not actually a colour. Over the 20th century a preference for far lighter shades of yellow through to cream prevailed, until today most yellow Labradors are of this shade. Also fawn has been a common colour in the yellow lab variety.
Interest in the darker shades of gold and fox red were re-established by English breeders in the 1980s, and three dogs were instrumental in this change: Balrion King Frost (black, born approx. 1976) who consistently sired "very dark yellow" offspring and is credited as having "the biggest influence in the re-development of the fox red shade",and his great-grandson, the likewise famous Wynfaul Tabasco (b.1986), described as "the father of the modern fox red Labrador", and the only modern fox red Show Champion in the UK. Other dogs, such as Red Alert and Scrimshaw Placido Flamingo, are also credited with passing on the genes into more than one renowned bloodline.
Chocolate labradors
Jack Vanderwyk traces the origins of all Chocolate labradors listed on the LabradorNet database (some 34,000 Labrador dogs of all shades) to eight original bloodlines. However, the shade was not seen as a distinct colour until the 20th century; before then according to Vanderwyk, such dogs can be traced but were not registered. A degree of crossbreeding with Flatcoat or Chesapeake Bay retrievers was also documented in the early 20th century, prior to recognition. Chocolate labradors were also well established in the early 20th century at the kennels of the Earl of Feversham, and Lady Ward of Chiltonfoliat.
The bloodlines as traced by Vanderwyk each lead back to three black labradors in the 1880s—Buccleuch Avon (m), and his sire and dam, Malmesbury Tramp (m), and Malmesbury June (f). Morningtown Tobla is also named as an important intermediary, and according to the studbook of Buccleuch Kennels, the chocolates in this kennel came through FTW Peter of Faskally (1908).

Description
A black Labrador from English stock.
Appearance
Labradors are relatively large, with males typically weighing 29 to 41 kg (64 to 90 lb) and females 25 to 32 kg (55 to 71 lb). Labradors weighing close to or over 100 lb (45 kg) are considered obese or having a major fault under American Kennel Club standards, although some Labradors weigh significantly more. The majority of the characteristics of this breed, with the exception of colour, are the result of breeding to produce a working retriever.
As with some other breeds, the Conformation (typically "English", "show" or "bench") and the Field (typically "American" or "working") lines differ, although both lines are bred in both countries. In general, however, Conformation Labradors tend to be bred as medium-sized dogs, shorter and stockier with fuller faces and a slightly calmer nature than their Field counterparts, which are often bred as taller, lighter-framed dogs, with slightly less broad faces and a slightly longer nose; however Field Labradors should still be proportional and fit within AKC standards. With field Labradors, excessively long noses, thin heads, long legs and lanky frames are not considered standard. These two types are informal and not codified or standardized; no distinction is made by the AKC or other kennel clubs, but the two types come from different breeding lines. Australian stock also exists; though not seen in the west, they are common in Asia.
The breed tends to shed hair twice annually, or regularly throughout the year in temperate climates. Some Labradors shed considerably; however, individual Labradors vary. Labrador hair is usually fairly short and straight, and the tail quite broad and strong. The webbed toes of the Labrador Retriever make them excellent swimmers. The webbing between their toes can also serve as a "snowshoe" in colder climates and keep snow from balling up between their toes- a condition that can be painful to other breeds with hair between the toes. Their interwoven coat is also relatively waterproof, providing more assistance for swimming.

Official breed standards
There is a great deal of variety among Labradors. The following characteristics are typical of the conformation show bred (bench-bred) lines of this breed in the United States, and are based on the AKC standard. Significant differences between UK and US standards are noted.
Size: Labradors are a relatively large breed. They should be as long from the withers to the base of the tail as they are from the floor to the withers. Males should stand 22.5 to 24.5 inches (57 to 62 cm) tall at the withers and weigh 65 to 80 lb (29 to 36 kg). Females should stand 21.5 to 23.5 inches (55 to 60 cm) and weigh 55 to 70 lb (25 to 32 kg). By comparison under UK Kennel Club standards, height should be 22 to 22.5 inches (56 to 57 cm) for males, and 21.5 to 22 inches (55 to 56 cm) for females.
Coat: The Lab's coat should be short and dense, but not wiry. The coat is described as 'water-resistant' or more accurately 'water-repellent' so that the dog does not get cold when taking to water in the winter. That means that the dog naturally has a slightly dry, oily coat. Acceptable colours are black, yellow (ranging from ivory or creme to fox red), and chocolate.
Head: The head should be broad with a pronounced stop and slightly pronounced brow. The eyes should be kind and expressive. Appropriate eye colours are brown and hazel. The lining around the eyes should be black. The ears should hang close to the head and are set slightly above the eyes.
Jaws: The jaws should be strong and powerful. The muzzle should be of medium length, and should not be too tapered. The jaws should hang slightly and curve gracefully back.
Body: The body should be strong and muscular with a level top line.
The tail and coat are designated "distinctive [or distinguishing] features" of the Labrador by both the Kennel Club and AKC. The AKC adds that "true Labrador Retriever temperament is as much a hallmark of the breed as the 'otter' tail."

Colour
The three primary color varieties of the Labrador Retriever
Labrador Retrievers are registered in three colours: black (a solid black colour), yellow (anything from light cream to "fox-red"), and chocolate (medium to dark brown). Some Labrador retrievers can have markings such as white patches on their chest and other areas, but most commonly they are one solid color.
Puppies of all colours can potentially occur in the same litter. Colour is determined primarily by three genes. The first gene (the B locus) determines the density of the coat's eumelanin pigment granules, if that pigment is allowed: dense granules result in a black coat, sparse ones give a chocolate coat. The second (E) locus determines whether the eumelanin is produced at all. A dog with the recessive e allele will produce only phaeomelanin pigment and will be yellow regardless of its genotype at the B locus. The genes known about previously have had their number increased by the introduction of the K locus, where the dominant "black" allele KB is now known to reside. Black or chocolate Labradors therefore must have the KB allele. Yellow Labradors are determined at the E locus, so the K locus is irrelevant in determining their colour. Variations in numerous other genes control the subtler details of the coat's colouration, which in yellow Labradors varies from white to light gold to a fox red. Chocolate and black Labradors' noses will match the coat colour.
According to a 2011 study, 13 out of 245 Labradors studied were heterozygous for the M264V mutation responsible for the melanistic mask, and one was homozygous. Within the breed, this trait is not visible.

Nose and skin pigmentation
Because Labrador colouration is controlled by multiple genes, it is possible for recessive genes to emerge some generations later and also there can sometimes be unexpected pigmentation effects to different parts of the body. Pigmentation effects appear in regard to yellow Labradors, and sometimes chocolate, and hence the majority of this section covers pigmentation within the yellow Labrador. The most common places where pigmentation is visible are the nose, lips, gums, feet, tail, and the rims of the eyes, which may be black, brown, light yellow-brown ("liver", caused by having two genes for chocolate), or several other colours. A Labrador can carry genes for a different color, for example a black Labrador can carry recessive chocolate and yellow genes, and a yellow Labrador can carry recessive genes for the other two colors. DNA testing can reveal some aspects of these. Less common pigmentations (other than pink) are a fault, not a disqualification, and hence such dogs are still permitted to be shown. The intensity of black pigment on yellow Labradors is controlled by a separate gene independent of the fur coloring. Yellow Labradors usually have black noses, which may gradually turn pink with age (called "snow nose" or "winter nose"). This is due to a reduction in the enzyme tyrosinase which indirectly controls the production of melanin, a dark coloring. Tyrosinase is temperature dependent—hence light colouration can be seasonal, due to cold weather—and is less produced with increasing age two years old onwards. As a result, the nose color of most yellow Labradors becomes a somewhat pink shade as they grow older.
A colouration known as "Dudley" is also possible. Dudleys are variously defined as yellow Labradors which have unpigmented (pink) noses (LRC), yellow with liver/chocolate pigmentation (AKC), or "flesh coloured" in addition to having the same colour around the rims of the eye, rather than having black or dark brown pigmentation. A yellow Labrador with brown or chocolate pigmentation, for example, a brown or chocolate nose, is not necessarily a Dudley, though according to the AKC's current standard it would be if it has chocolate rims around the eyes (or more accurately of the genotype eebb). Breed standards for Labradors considers a true Dudley to be a disqualifying feature in a conformation show Lab, such as one with a thoroughly pink nose or one lacking in any pigment along with flesh coloured rims around the eyes. True Dudleys are extremely rare.
Breeding in order to correct pigmentation often lacks dependability. Because colour is determined by many genes, some of which are recessive, crossbreeding a pigmentation non-standard yellow Labrador to a black Labrador may not correct the matter or prevent future generations carrying the same recessive genes. For similar reasons, crossbreeding chocolate to yellow Labradors is also often avoided.

Show and field lines
Head and muzzle appearance: American or field (left), and English or show (right), showing the shorter muzzle length, more solid appearance head, and "pronounced" stop of the latter.
There are significant differences between field and trial-bred (sometimes referred to as "American") and show-bred (or "English") lines of Labradors, arising as a result of specialised breeding. Dogs bred for hunting and field-trial work are selected first for working ability, where dogs bred to compete in conformation shows are selected for their conformation to the standards and characteristics sought by judges in the show ring.
While individual dogs may vary, in general show-bred Labradors are heavier built, slightly shorter-bodied, and have a thicker coat and tail. Field Labradors are generally longer legged, lighter, and more lithe in build. In the head, show Labradors tend to have broader heads, better defined stops, and more powerful necks, while field Labradors have lighter and slightly narrower heads with longer muzzles. Field-bred Labradors are commonly higher energy and more high-strung compared to the Labrador bred for conformation showing, and as a consequence may be more suited to working relationships than being a "family pet".Some breeders, especially those specialising in the field type, feel that breed shows do not adequately recognise their type of dog, leading to occasional debate regarding officially splitting the breed into subtypes.
In the United States, the AKC and the Labrador's breed club have set the breed standard to accommodate the field-bred Labrador somewhat. For instance, the AKC withers-height standards allow conformation dogs to be slightly taller than the equivalent British standard. However, dual champions, or dogs that excel in both the field and the show ring, are becoming more unusual.

Temperament

The AKC describes the Labrador's temperament as a kind, outgoing and tractable nature. Labradors' sense of smell allows them to hone in on almost any scent and follow the path of its origin. They generally stay on the scent until they find it. Labradors instinctively enjoy holding objects and even hands or arms in their mouths, which they can do with great gentleness (a Labrador can carry an egg in its mouth without breaking it). They are also known to have a very soft feel to the mouth, as a result of being bred to retrieve game such as waterfowl. They are prone to chewing objects (though they can be trained out of this behavior). The Labrador Retriever's coat repels water to some extent, thus facilitating the extensive use of the dog in waterfowl hunting.

Labradors have a reputation as a very even-tempered breed and an excellent family dog. This includes a good reputation with children of all ages and other animals. But some lines (particularly those that have continued to be bred specifically for their skills at working in the field rather than for their appearance) are particularly fast and athletic. Their fun-loving boisterousness and lack of fear may require training and firm handling at times to ensure it does not get out of hand—an uncontrolled adult can be quite problematic. Females may be slightly more independent than males. Labradors mature at around three years of age; before this time they can have a significant degree of puppy-like energy, often mislabelled as being hyperactive. Because of their enthusiasm, leash-training early on is suggested to prevent pulling when full-grown. Labradors often enjoy retrieving a ball endlessly and other forms of activity (such as agility, frisbee, or flyball).
Although they will sometimes bark at noise, especially noise from an unseen source ("alarm barking"), Labradors are usually not noisyor territorial. They are often very easygoing and trusting with strangers, and therefore are not usually suitable as guard dogs.
Labradors have a well-known reputation for appetite, and some individuals may be highly indiscriminate, eating digestible and non-food objects alike. They are persuasive and persistent in requesting food. For this reason, the Labrador owner must carefully control his/her dog's food intake to avoid obesity and its associated health problems (see below).
The steady temperament of Labradors and their ability to learn make them an ideal breed for search and rescue, detection, and therapy work. They are a very intelligent breed. They are ranked # 7 in Stanley Coren's The Intelligence of Dogs. The AKC describes the breed as an ideal family and sporting dog. Their primary working role in the field continues to be that of a hunting retriever.

They do not typically jump high fences or dig. Because of their personalities, some Labradors climb and/or jump for their own amusement. As a breed they are highly intelligent and capable of intense single-mindedness and focus if motivated or their interest is caught. Therefore, with the right conditions and stimuli, a bored Labrador could "turn into an escape artist par excellence".
Labradors as a breed are curious, exploratory and love company, following both people and interesting scents for food, attention and novelty value. In this way, they can often "vanish" or otherwise become separated from their owners with little fanfare. They are also popular dogs if found, and at times may be stolen. Because of this a number of dog clubs and rescue organizations (including the UK's Kennel Club) consider it good practice that Labradors be microchipped, with the owner's name and address also on their collar and tags.

Use as working dogs
Labradors are an intelligent breed with a good work ethic and generally good temperaments (breed statistics show that 92.3% of Labradors who were tested passed the American Temperament Test) Common working roles for Labradors include: hunting, tracking and detection (they have a great sense of smell which helps when working in these areas), disabled-assistance, carting, and therapy work. Approximately 60–70% of all guide dogs in Canada are Labradors; other common breeds are Golden Retrievers and German Shepherd Dogs.
Labradors are powerful and indefatigable swimmers noted for their ability to tolerate the coldest of water for extended periods of time. Their ability to work quietly alongside hunters while watching for birds to fall from the sky, marking where they land, and then using their outstanding nose to find and retrieve dead or wounded birds has made them the king of waterfowl retrievers.

They are also used for pointing and flushing and make excellent upland game hunting partners.
The high intelligence, initiative and self-direction of Labradors in working roles is exemplified by dogs such as Endal, who during a 2001 emergency placed an unconscious human being in the recovery position, retrieved his mobile phone from beneath the car, fetched a blanket and covered him, barked at nearby dwellings for assistance, and then ran to a nearby hotel to obtain help. A number of Labradors have also been taught to assist their owner in removing money and credit cards from ATMs with prior training.
The breed is used in water rescue/lifesaving. It continues in that role today, along with the Leonberger, Newfoundland and Golden Retriever dogs; they are used at the Italian School of Canine Lifeguard

Health
Many dogs, including Labradors such as this twelve year old, show distinct whitening of the coat as they grow older; especially around the muzzle.
Labrador pups generally are not brought to the home before they are 8 weeks old. Their life expectancy is generally 10 to 12 years, and it is a healthy breed with relatively few major problems. Notable issues related to health and well-being include:
Inherited disorders
Labradors are somewhat prone to hip and elbow dysplasia, especially the larger dogs, though not as much as some other breeds. Hip scores are recommended before breeding and often joint supplements are recommended.
Labradors also suffer from the risk of knee problems. A luxating patella is a common occurrence in the knee where the knee dislocates and goes back into place.
Eye problems are also possible in some Labradors, particularly progressive retinal atrophy, cataracts, corneal dystrophy and retinal dysplasia. Dogs which are intended to be bred should be examined by a veterinary ophthalmologist for an eye score.
Hereditary myopathy, a rare inherited disorder that causes a deficiency in type II muscle fibre. Symptoms include a short stilted gait or "bunny hopping," and in rare cases ventroflexion of the neck accompanied by a kyphotic posture.
There is a small incidence of other conditions, such as autoimmune diseases and deafness in Labradors, either congenitally or later in life.
Labradors often suffer from exercise induced collapse, a syndrome that causes hyperthermia, weakness, collapse, and disorientation after short bouts of exercise.

Obesity
Labradors like to eat and without adequate exercise, can become obese. Laziness also contributes to this. Obesity is a serious condition, and can be considered the number one nutritional problem with dogs. A study shows that at least 25% of dogs in the United States are overweight. Therefore Labradors must be properly exercised and stimulated. A healthy Labrador can do swimming wind sprints for two hours, and should keep a very slight hourglass waist and be fit and light, rather than fat or heavy-set. When they are fat, they usually develop hip dysplasia or other joint problems and get diabetes. Osteoarthritis is common in older, especially overweight, Labradors. A 14 year study covering 48 dogs by food manufacturer Purina showed that Labradors fed to maintain a lean body shape outlived those fed freely, by around two years, emphasizing the importance of not over-feeding. 


Appearance around the world
In the United States, the breed gained wider recognition following a 1928 American Kennel Gazette article, "Meet the Labrador Retriever". Before this time, the AKC had only registered 23 Labradors in the country, in part because US and UK hunting styles had different requirements. Labradors acquired popularity as hunting dogs during the 1920s and especially after World War II, as they gained recognition as combining some of the best traits of the two favourite United States breeds as both game finders and water dogs.
Outside North America and Western Europe, the Labrador arrived later. For example, the Russian Retriever Club traces the arrival of Labradors to the late 1960s, as household pets of diplomats and others in the foreign ministry.  The establishment of the breed in the Commonwealth of Independent States (former USSR) was initially hindered by the relatively small numbers of Labradors and great distances involved, leading to difficulty establishing breedings and bloodlines; at the start of the 1980s, home-born dogs were still regularly supplemented by further imports from overseas. Difficulties such as these initially led to Labradors being tacitly cross-bred to other types of retriever. In the 1990s, improved access to overseas shows and bloodlines is said to have helped this situation become regularised.

Pomeranian

History
The Pomeranian (often known as a Pom, or more humorously, Pom Pom) is a breed of dog of the Spitz type, named for the Pomerania region in Central Europe (today part of eastern Germany and northern Poland). Classed as a toy dog breed because of its small size, the Pomeranian is descended from the larger Spitz type dogs, specifically the German Spitz. It has been determined by the Fédération Cynologique Internationale to be part of the German Spitz breed, and in many countries, they are known as the Zwergspitz (~Dwarf Spitz).
The breed has been made popular by a number of royal owners since the 17th century. Queen Victoria owned a particularly small Pomeranian and consequently the smaller variety became universally popular. During Queen Victoria's lifetime alone, the size of the breed decreased by 50%. Overall, the Pomeranian is a sturdy, healthy dog. The most common health issue is Luxating patella. Tracheal collapse can also be an issue. More rarely, the breed can suffer from a skin condition colloquially known as "black skin disease", or alopecia ex. This is a genetic disease which causes the dog's skin to turn black and lose all or most of its hair. The breed is currently among the top 15 most popular in the USA, and the current fashion for small dogs has increased their popularity worldwide.


Description

Pomeranians are small dogs weighing 1.9–3.5 kilograms (4.2–7.7 lb) and standing 5.0–11 inches (13–28 cm) high at the withers. They are compact but sturdy dogs with an abundant textured coat with a highly plumed tail set high and flat. The top coat forms a ruff of hair on the neck and back, and they also have a fringe of feathery hair on the hindquarters.
 The earliest examples of the breed were white or occasionally black, Queen Victoria adopted a small red Pomeranian in 1888, which caused that color to become fashionable by the end of the 19th century. In modern times, the Pomeranian comes in the widest variety of colors of any dog breed, including white, black, brown, red, orange, cream, blue, sable, black and tan, brown and tan, spotted, brindle, plus combinations of those colors. The most common colors are orange, black or cream/white.
The merle Pomeranian is a recent color developed by breeders. It is a combination of a solid base color with lighter blue/grey patch which gives a mottled effect. The most common base colors for the effect are red/brown or black, although it can also appear with other colors. Combinations such as brindle merle or liver merle are not accepted in the breed standard. In addition, the eye, nose and paw pad colors are different in merles, changing parts of the eye to blue and the color on the nose and paw pads to become mottled pink and black.
Pomeranians have a thick double coat, and while grooming is not difficult, breeders recommend that it is done daily because of the thickness of the coat and the constant shedding. The outer coat is long, straight, and harsh in texture while the undercoat is soft, thick and short. The coat knots and tangles easily, particularly when the undercoat is being shed, which happens twice a year.


Behavior
Pomeranians are typically a very friendly and lively breed of dog. They love to be around their owners and are known to be protective of them. They bond quickly with their owners, and can suffer from separation anxiety if not trained to spend time alone. Pomeranians are alert and aware of changes in their environment and barking at new stimuli can develop into a habit of barking excessively in any situation. They are somewhat defensive of their territory and will thus bark when they encounter any outside noises. Pomeranians are intelligent dogs, respond well to training, and can be very successful in getting what they want from their owners.

Shih Tzu

Description
The Shih Tzu; Mandarin is a breed of dog weighing 4–7.25 kilograms (8.8–16.0 lb) with long silky hair. The breed originated in China and is among the earliest breeds. Shih Tzu were officially recognized by the American Kennel Club in 1969. The name is both singular and plural.
A small dog with a short muzzle and large deep dark eyes, with a soft long, double coat, the Shih Tzu stands no more than 26.7 cm (1012 in.) at the withers and with an ideal weight of 4.5 to 7.3 kg (10 to 16 lbs). Drop ears are covered with long fur, and the heavily furred tail is carried curled over the back. The coat may be of any color, although a blaze of white on the forehead and tail-tip is frequently seen. The Shih Tzu is slightly longer than tall, and dogs ideally should carry themselves "with distinctly arrogant carriage." A very noticeable feature is the underbite, which is required in the breed standard. The traditional long silky glossy coat that reaches the floor requires daily brushing to avoid tangles. Because of their long coat and fast growing hair, regular grooming is necessary which may be a costly expense and should be considered when looking at this breed. Often the coat is clipped short to simplify care, in a "puppy clip". For conformation showing, the coat must be left in its natural state, although trimming for neatness around the feet and anus is allowed.


History
DNA analysis placed the ancestors of today's Shih Tzu breed in the group of "ancient" breeds indicating "close genetic relationship to wolves". Ludvic von Schulmuth studied the skeletal remains of dogs found in human settlements as long as ten thousand years ago. Von Schulmuth created a genealogical tree of Tibetan dogs that shows the "Gobi Desert Kitchen Midden Dog", a scavenger, evolved into the "Small Soft-Coated Drop-Eared Hunting Dog who would fight lions in packs " which evolved into the Tibetan Spaniel, Pekingese, and Japanese Chin. Another branch coming down from the "Kitchen Midden Dog" gave rise to the Papillon and Long-haired Chihuahua and yet another "Kitchen Midden Dog" branch to the Pug and Shih Tzu. The Shih Tzu was almost completely wiped out during the Chinese Revolution. Seven males and seven females were saved, and today, all shih tzus can be traced back to one of these dogs.
There are various theories of the origins of today's breed. Theories relate that it stemmed from a cross between Pekingese and a Tibetan dog called the Lhasa Apso; that the Chinese court received a pair as a gift during the Tang Dynasty (618–907 AD); and that they were introduced from Tibet to China in the mid-18th century (Qing Dynasty. Dogs during that time were selectively bred and seen in Chinese paintings. The first dogs of the breed were imported into Europe (England and Norway) in 1930, and were classified by the Kennel Club as "Apsos". The first European standard for the breed was written in England in 1935 by the Shih Tzu Club, and the dogs were recategorised as Shih Tzu. The breed spread throughout Europe, and was brought to the United States after World War II, when returning members of the US military brought back dogs from Europe. The Shih Tzu was recognised by the American Kennel Club in 1969 in the Toy Group. The breed is now recognised by all of the major kennel clubs in the English-speaking world, It is also recognised by the Fédération Cynologique Internationale for international competition in Companion and Toy Dog Group.


Names and etymology
Shih Tzu (literally "Lion Dog"), is the Chinese name rendered according to the Wade-Giles system of romanization in use when the breed was first introduced in America; the Chinese pronunciation is approximately shirr-tsə. The name translates as Lion Dog, so named because the dog was bred to resemble "the lion as depicted in traditional oriental art," such as the Chinese guardian lions. The Shih Tzu is also often known as the "Xi Shi quan", based on the name of Xi Shi, regarded as one of the most beautiful woman of ancient China, and, less often, the Chrysanthemum Dog, a nickname coined in England in the 1930s. The dog may also be called the Tibetan Lion Dog, but whether or not the breed should be referred to as a Tibetan or Chinese breed is a source of argument, the absolute answer to which "may never be known".
