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 Dorsetshire. 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 colors, 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 in the fifth edition of his book Introductions to Young Sportsman, published in 1846.
The first photograph of the breed was taken in 1857 (the Earl of Home's dog "Nell", described both as a Labrador and a St. John's water 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 recognized by the Kennel Club in 1903. The first American Kennel Club (AKC) registration was in 1917. The Liver (now typically called Chocolate) Labrador emerged in the late 1800s, with liver-colored pups documented 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 12 December 1938 issue.
Behavior
This king of retrievers is highly active, agile, confident, and tenacious. Sometimes called the "pointer of retrievers", he has a remarkably keen nose and is an excellent swimmer. He can retrieve all sorts of game on land and in the water. With his vast visual memory, he can recall the locations of several fallen birds. A tenacious tracker, he is a good bloodhound on the trail of wounded large game. Very even-tempered and never aggressive, he has a delightful personality that makes him a wonderful pet. He needs firm and gentle training.
He does not like being left alone. He needs lots of exercise to curb his restlessness. He must be brushed two to three times per week and combed during shedding season.
Function
Labrador Retrievers have proven to have a high success rate at becoming guide dogs. A study was recently done on how well four different breeds (Labrador Retriever, Golden Retriever, Labrador Retriever/Golden Retriever Mix, and German Shepherds) trained to become guide dogs. In this experiment, German Shepherds had the highest chance of not completing it. Labrador Retrievers and Labrador Retriever/Golden Retriever Mix 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.
Labradors are powerful and determined 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 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. 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
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. They 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. Labradors like to eat, and without proper 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. 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. Obesity can exacerbate conditions such as hip dysplasia and joint problems, and can lead to secondary diseases, including diabetes. Osteoarthritis is common in older, especially overweight, Labradors. Labradors should be walked twice a day for at least half an hour.
