Labrador Retriever

The Labrador Retriever (simply Labrador, or Lab for short) is one of several kinds of retriever, a type of gun dog. Even-tempered and well-behaved around young children and the elderly, Labradors are athletic and playful, and are the most popular breed of dog by registered ownership in Australia, Canada, New Zealand,the United Kingdom,and the United States (since 1991).A favorite assistance dog breed in these and other countries, Labradors are frequently trained to aid blindand autistic people, act as therapy dogs, and perform screening and detection work for law enforcement and other official agencies.

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.

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.

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. The Labrador retriever is actually from Newfoundland; exceptionally, the Newfoundland (dog) was created near the same time in Labrador. The two breeds' names and origins were mixed once moved into England and the Americas. The dog from Labrador became the large, long furred dog we see and know today, and the dog from Newfoundland became the Labrador.

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 first dog to appear on the cover of Life Magazine was a black Labrador Retriever called ‘Blind of Arden’ in the December, 12th, 1938 issue. 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 in 1899, and chocolate Labradors became more established in the 1930s., There is also a significant difference between show Labs, which tend to be short legged and very heavy, and field Labs which have a more functional and athletic build. Generally these two subtypes have different general features such as facial or body types.

Yellow (and similar 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 c. 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

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 standardised; 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. These dogs are also very good with children.
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.

Colour

The three primary colour varieties of the Labrador Retriever
Labrador Retrievers are registered in three colours: black (a solid black colour), yellow (anything from the colour that some breeders sell as white or cream to "fox-red"), and chocolate (medium to dark brown). Some dogs are sold as "silver" pure-bred Labradors, but purity of those bloodlines is currently under dispute. Major kennel clubs around the world allow Silver Labradors to be registered, but not as 'Silver'. The Kennel Club (England) requires that they be registered as 'Non-recognized'. The parent club for the Labrador Retriever in the USA (the LRC) states publicly that 'There is no genetic basis for the silver gene in Labradors'. Occasionally Labradors will exhibit small amounts of white on their chest, paws or tail, and rarely a purebred Lab will exhibit brindling (stripes) or tan points similar to a Rottweiler.These markings are a disqualification for show dogs but do not have any bearing on the dog's temperament or ability to be a good working or pet dog.
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 previouslyhave 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.
