Labrador Retriever

History

The Labrador breed dates back to at least the 1830s, when St. John's water dogs bred by European settlers in Newfoundland were first introduced to Britain from ships trading between Canada and Poole in Dorset. These were then bred with British hunting dogs to create what became known as the Labrador Retriever. Its early patrons included the Earl of Malmesbury, the Duke of Buccleuch, the Earl of Home, and Sir John Scott. Early writers have confused the Labrador with the much larger Newfoundland and the Lesser Newfoundland, with Charles St. John even referring to the Lesser Newfoundland as the Newfoundland. Colonel Peter Hawker describes the first Labrador as being not larger than an English Pointer, more often black than other colours, long in its head and nose with a deep chest, fine legs, and short and smooth coat, and did not carry its tail as highly as the Newfoundland. Hawker distinguishes the Newfoundland from both the "proper Labrador" and St. John's breed of these dogs

By 1870 the name Labrador Retriever had become common in England. The liver (now usually called chocolate) Labrador emerged in the late 1800s, with liver-coloured pups documented at the Buccleuch kennels in 1892; the first yellow Labrador on record was born in 1899 (Ben of Hyde, kennels of Major C.J. Radclyffe). The breed was recognised by the Kennel Club in 1903. The first American Kennel Club (AKC) registration was in 1917.

Characteristics

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 American Kennel Club standard.{{cite web | access-date = 13 September 2007}} Significant differences between UK and US standards are noted.

• Size: Labradors are a medium-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. The AKC standard includes an ideal weight for dogs of 55 - and for bitches as 55 -. The guidelines for height vary between the AKC, which gives 21.5 to for dogs and 21.5 to for bitches, The Kennel Club which advises that dogs should be 56 to with bitches between 55 and, and the FCI which quotes a range of 56 to for dogs with bitches ideal at 54 to.
• Coat: The Labrador Retriever's coat should be short and dense, but not wiry. The coat is water-resistant, so the dog does not get cold when taking to the water in the winter. That means that the dog naturally has a slightly dry, oily coat. Acceptable colours are black, yellow, and chocolate.
• Head: The head should be broad with slightly pronounced eyebrows. 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 be 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 have a powerful and muscular build.

The tail and coat are designated "distinctive [or distinguishing] features" of the Labrador by both the Kennel Club and AKC. The AKC adds that the "true Labrador Retriever temperament is as much a hallmark of the breed as the 'otter' tail."

Colour

Main article: Labrador Retriever coat colour genetics

Labradors are registered in three colours: Solid black, yellow (anything from creamy white to fox-red), and chocolate (medium to dark brown; originally called "liver"). |access-date=10 January 2015 |archive-url=https://web.archive.org/web/20150110200738/http://www.thekennelclub.org.uk/services/public/breed/colours.aspx?id=2048 |archive-date=10 January 2015

Puppies of all colours can occur in the same litter. Coat colour is determined primarily by three genes, called MC1R, Agouti, and CBD103. If a dog carries wild type alleles at all three loci, the dog will have a yellow coat. If a dog has a loss-of-function mutation at MC1R, it will also have a yellow coat, regardless of the genotypes at the other two loci. Dogs carrying wild-type alleles for MC1R and Agouti, together with the black allele of CBD103, will have a black coat. "Production of yellow versus black pigment in dogs is controlled by three genes: MC1R, Agouti, and CBD103. Dogs carrying wild-type alleles for all three genes have a yellow coat resulting from Agouti antagonism of MC1R signaling in melanocytes (yellow Great Dane, top). Dogs carrying a loss-of-function mutation at MC1R have a yellow coat, regardless of their genotype at Agouti or CBD103 (yellow Labrador retriever, middle). Dogs carrying wild-type alleles for MC1R and Agouti, together with the dominant black allele of CBD103 (KB) have a black coat resulting from the interaction between a β-defensin and MC1R (black Curly Coated Retriever,

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 this breed, the trait cannot be determined simply by appearance.

Show and field lines

As a result of specialised breeding, there are significant differences between field and trial-bred and show-bred lines of Labradors. In the United States, the former are sometimes mistakenly referred to as "American" and the latter as "English." In fact, both field and show types are bred in both countries and all Labrador Retrievers are descended from British lines.

Health

Labrador Retrievers have a predisposition to chronic hepatitis. One UK study found a 4.14 odds ratio. Some studies report a predilection for Labrador Retriever bitches. The reason for the predilection is unknown. Ideas proposed include it being hereditary or environmental. The Labrador Retriever also shows a predisposition to other hepatobiliary diseases, including: reactive hepatitis, nodular hyperplasia, and gall bladder disease.

A UK study found the breed's average life expectancy to be 13.1 years. A joint study by the Royal Veterinary College study and The University of Sydney, concluded that chocolate-coloured Labradors have a shorter average life expectancy than other colours of Labrador (by about 10%) and are more likely to suffer some health problems. A 2024 Italian study found a life expectancy of 11 years for the breed compared to 10 years overall. A 2005 Swedish study of insurance data found that 25% of Labrador Retrievers died by the age of 10, less than the overall rate of 35% of dogs dying by the age of 10.

Labradors are somewhat prone to hip and elbow dysplasia,{{cite web |access-date=14 September 2007 |archive-url=https://web.archive.org/web/20070927174957/http://www.upei.ca/~cidd/breeds/labradorretriever2.htm |archive-date=27 September 2007

The Labrador Retriever is one of the more commonly affected breeds for progressive rod-cone degeneration. An autosomal recessive mutation in the PRCD gene is responsible for the condition in the breed.

Roles

Labrador Retrievers have proven to have a high success rate at becoming guide dogs. A study published in 2006, tested the suitability of four different breeds (Labrador Retriever, Golden Retriever, Labrador Retriever/Golden Retriever Mix, and German Shepherds) as guide dogs. In this experiment, German Shepherds had the highest chance of not completing it. Labrador Retrievers and the Labrador Retriever/Golden Retriever Crossbreeds had the highest success rate. However, German Shepherds and Golden Retrievers had a higher success rate after going through longer training than the training required for Labrador Retrievers.

The Labrador Retriever is a gun dog bred to retrieve on land and water. As a dog specially bred for water retrieving, the Labrador has developed various traits for this job. For retrieving the Labrador Retriever has a soft mouth, a trait that allows it to carry game and waterfowl without damaging it. And for swimming, the Labrador is aided by fully webbed paws, an otter-like tail, and a waterproof coat.

The high intelligence, initiative and self-direction of Labradors in working roles is exemplified by dogs such as Endal, who was trained to, if need be, put his human who uses a wheelchair in the recovery position, cover him with a blanket, and activate an emergency phone.{{cite news | archive-url=https://web.archive.org/web/20130517024250/http://archives.cnn.com/2000/HEALTH/08/10/super.dog/index.html | archive-date=17 May 2013 | access-date = 28 February 2007 }}

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.

In war

Labradors have been used as war dogs.

• World War II: Labradors were trained for tasks such as bomb detection and handling dangerous situations.
• Vietnam War: Labradors served as tracker dogs, alerting handlers to snipers, tripwires, and weapons caches. Their training enabled them to locate injured enemies, missing personnel, or enemy positions.
• Modern military use: Labradors continue to serve in roles such as bomb detection and search and rescue operations. Their calm demeanor and adaptability make them suitable for various military tasks.

Demography

Main article: List of most popular dog breeds

The Labrador is an exceptionally popular dog. As of 2006, it was widely considered the most popular breed in the world, and it is the most popular dog by ownership in Canada, New Zealand and the United Kingdom. In 2006, in both the United Kingdom and the United States, there were well over twice as many registered Labradors as the next most popular breed. If the comparison is limited to dog breeds of a similar size, then there are around 3–5 times as many Labradors registered in both countries as the next most popular breeds, the German shepherd dog and Golden retriever.

Labs are the most popular breed of assistance dog in the United States, Australia, and many other countries, as well as being widely used by police and other official bodies for their detection and working abilities. Approximately 60–70% of all guide dogs in the United States are Labradors.

In 2022, Labrador Retrievers were the second most popular breed in the United States. In 2020, the Labrador was the most popular registered dog breed in New Zealand.

Seven out of the thirteen "outstanding gundogs" of the Australian National Kennel Council's 2000–2005 appointees to its 'hall of fame' are Labradors. | access-date = 13 September 2007 | archive-url = https://web.archive.org/web/20070919113122/http://www.ankc.aust.com/hall_of_fame.html | archive-date = 19 September 2007
