Labrador Retriever




The Labrador Retriever (also Labrador, Labby or Lab for short), is one of several kinds of retriever, a type of gun dog. The Labrador is considered the most popular breed of dog (by registered ownership) in the world, and is by a large margin the most popular breed by registration in the United States (since 1991) the United Kingdom, Poland, and several other countries. It is also 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. They are exceptionally affable, gentle, intelligent, energetic and good natured, and Labradors are generally considered good companions for people of all ages (including a high level of patience and tolerance for children,making them both excellent companions and working dogs. Although somewhat boisterous if untrained, Labrador Retrievers respond well to praise and positive attention, and are considerably "food and fun" oriented. These dogs are loyal and good with little children. They may be used in shows. With training, the Labrador is one of the most dependable, obedient and multi-talented breeds in the world.
Appearance

Labradors are relatively large, with males typically weighing 30–36 kg (65–80 lb) and females 25–32 kg (55–70 lb). Labs weighing close to or over 100 lbs are considered
obese or having a major fault under American Kennel Club standards, although some labs weigh significantly more. Their coats are short and smooth, and they possess a straight, powerful tail often likened to that of an otter. 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 English (typically "show" or "bench") and the American (typically "working" or "field") lines differ. Today, "English" and "American" lines exist in both the United Kingdom and in North America. In general, however, in the United Kingdom, Labs tend to be bred as medium-sized dogs, shorter and stockier with fuller faces and a slightly calmer nature than their American counterparts, which are regionally often bred as taller, lighter-built dogs. 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. Other "local minor variants" may also exist in some areas.
The breed tends to
shed hair twice annually, or regularly throughout the year in temperate climates. Some labs shed a lot; however, individual labs vary. Labrador hair is usually fairly short and straight, and the tail quite broad and strong. The otter-like tail and webbed toes of the Labrador Retriever make them excellent swimmers. Their interwoven coat is also relatively waterproof, providing more assistance for swimming. The tail acts as a rudder for changing direction.
Colour

There are three recognised colours for Labs: black (a solid black colour), yellow (anything from light cream to gold to "fox-red"), and chocolate (medium to dark brown). There are no such things as silver or golden Labradors, a common mistake for the Yellow variant. There is also a black-and-tan coat type, but this coat colour is the least popular as it renders the Labrador un-showable except in the UK.
Puppies of all colours can potentially occur in the same
litter. Colour is determined primarily by two genes. The first gene (the B locus) determines the density of the coat's pigment granules: dense granules result in a black coat, sparse ones give a chocolate coat. The second (E) locus determines whether the pigment is produced at all. A dog with the recessive e allele will produce little pigment and will be yellow regardless of its genotype at the B locus. Variations in numerous other genes control the subtler details of the coat's colouration, which in yellow Labs varies from white to light gold to a fox red. Chocolate and black Labs' noses will match the coat colour
Temperament

Labradors are a well-balanced, friendly and versatile breed, adaptable to a wide range of functions as well as making very good pets. As a rule they are not excessively prone to being territorial, pining, insecure, aggressive, destructive, hypersensitive, or other difficult traits which sometimes manifest in a variety of breeds, and as the name suggests, they are excellent retrievers. As an extension of this, they 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.

Labs, like other dogs, may often tend to dig like this 3 month old and are generally very friendly with other dogs, like this German Shepherd.
Labradors have a reputation as a very mellow breed and an excellent family dog (including 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 puppyish energy, often mislabeled as being
hyperactive. Because of their enthusiasm, leash-training early on is suggested to prevent pulling when full-grown. Labs often enjoy retrieving a ball endlessly and other forms of activity (such as agility, frisbee, or flyball). They are considerably "food and fun" oriented, very trainable, and open-minded to new things, and thrive on human attention, affection and interaction, of which they find it difficult to get enough. Reflecting their retrieving bloodlines, almost every Lab loves playing in water or swimming.

This sociable labrador pup has become acquainted with a kitten.
Although they will sometimes
bark at noise, especially a degree of "alarm barking" when there is noise from unseen sources, Labs are not on the whole noisy or territorial, and 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.

The steady temperament of Labs and their ability to learn make them an ideal breed for search and rescue, detection, and therapy work. Their primary working role in the field continues to be that of a hunting retriever.
Health and well-being

Many dogs, including Labs such as this ten year old, show distinct whitening of the coat as they grow older; especially around the muzzle.
Labrador pups should not be brought home before they are 7–10 weeks old. Their life expectancy is generally
12 to 13 years or a few years longer with good medical care and proper feeding, and it is a healthy breed with relatively few major problems. Notable issues related to health and wellbeing include:

Inherited disorders
Labs 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.
Labs also suffer from the risk of knee problems. A
luxating patella is a common occurrence in the knee where the leg is often bow shaped.
Eye problems are also possible in some Labs, 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.
There is a small incidence of other conditions, such as
autoimmune diseases and deafness in labs, either congenitally or later in life.

Golden Retriever


The Golden Retriever is a breed of dog, historically developed as a gundog to retrieve shot waterfowl and upland game during hunting. As such they were bred to have a soft mouth to retrieve game undamaged and an instinctive love of water. Their intelligence and versatility sees them employed in a variety of roles including illegal drug detection, search and rescue, as hunting dogs and as guide dogs. Its friendly, eager-to-please and patient demeanor has also made it one of the most popular family dogs (by registration) in the world today.
Appearance

British type

Some variation exists between the British type Golden Retrievers prevalent throughout Europe and Australia, and those of American lines and these differences are reflected in the breed standards. This type is bigger-boned, shorter, with a more square head and or muzzle and are generally slightly heavier. Males should be between 56–61 cm (22–24 inch) at the withers and females slightly shorter at between 51–56 cm (20–22 inch). 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 American line dogs tend to be set further apart than those of British lines and can appear to be slanted and triangular in shape by comparison. 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 America lines white is an unacceptable colour in the show ring. The British KC standard is used in all countries with the exceptions of the US and Canada. Some breeders of this type in America may import their dogs to improve bloodlines.

American type

The ideal Golden is athletic, and well balanced. It is a symmetrical, and active dog. An American Golden is less stocky and lankier than a British. A male should stand from 22–24 inch (58–61 cm) in height at the shoulders, and females should be 21.5–22.5 inch (55–57 cm) at the shoulders. The males weigh 60–80 lb and the females weigh 55–70 lb. The coat is dense and water repellent, in various shades of lustrous gold, with moderate feathering. Excessive length, lightness, or darkness is undesirable. The gait should be free, smooth, powerful, and well-coordinated. They originated in Scotland during the late nineteenth century and were a mix of the Tweed Water Spaniel, which is now extinct, and the Wavy-Coated Retriever.
Field line Golden Retrievers tend to be smaller and have a less dense coat than their conformation line counterparts. And usually, they are darker in color.

Golden Retrievers vary widely in coat

The coat is dense and waterproof, and may be straight or moderately wavy. It usually lies flat against the belly. 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 color up to a judge's discretion when competing in conformation shows. Therefore, "pure white" and "red" are unacceptable colors for the Golden coat. The Kennel Club (UK) also permits cream as an acceptable coat color. Judges may also disallow Goldens with pink noses, or those lacking pigment. The Golden's coat can also be of a mahogany color, 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 darker colouration at the tips of the ears may indicate a darker adult color. 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

Most Goldens need plenty of exercise, such as dog agility.

Golden Retrievers were bred to retrieve from the water.
The temperament of the Golden Retriever is a hallmark of the breed and is described in the standard as "kindly, friendly and confident". 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.
As the name suggests, the Golden Retriever loves to retrieve. Whether the object is a thrown stick,
tennis ball, or flying disc, retrieving can keep a dog of this breed occupied and entertained for hours, particularly if water is also involved. Goldens might also pick up and "retrieve" any object that is near to them upon their masters' arrival, all of this lending to their retriever name.[citation needed]
Goldens are also noted for their intelligence, and can learn up to roughly 240 commands, words and phrases. 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 demeanor 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 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. In fact, the first AKC Obedience Trial Champion was a Golden Retriever. They are also very competitive in agility and other performance events. Harsh training methods are unnecessary, and that Golden Retrievers respond 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 its adopted even though it may not have been pregnant or nursing recently.

Care

Golden Retrievers are moderately active dogs, and require a reasonable amount of exercise each day, although exercise needs may vary depending on the individual dog and its age. They are a breed that is prone to obesity, and as such the average Golden Retriever should never be treated like a small dog, or sedentary house pet. Some dogs may be too active to be easily exercised by elderly owners.
Goldens should be groomed at least once a week, and every day during heavy shedding. Their coats shed somewhat during the year, but are known to "blow coat" twice a year when they shed profusely. They also need to have their ears cleaned regularly, or otherwise an ear infection might occur. While shedding is unavoidable with Golden Retrievers, frequent grooming (daily to weekly) lessens the amount of hair shed by the animal. Severe
shedding resulting in bald patches can be indicative of stress or sickness in a Golden Retriever.
Golden Retrievers are very attached to their owners. Leaving them alone in a room can cause the dog to become very sad and distressed. They have a need to always have something in their mouth, and like to carry things around. They are great athletes and must be walked daily, or they will become restless and anxious. This makes them an ideal family pet.

History

The Golden Retriever breed was originally developed in Scotland and England at "Guisachan" near Glen Affric, the highland estate of Sir Dudley Marjoribanks (pronounced "MarĘ’banks"), later Baron Tweedmouth. For many years, there was controversy over which breeds were originally crossed. In 1952, the publication of Majoribanks' 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 Golden Retriever to fill this role.

Goldens excel at retrieving in water

The original cross was of a yellow-colored Retriever, Nous, with a Tweed Water Spaniel female dog, Belle.[citation needed] The Tweed Water Spaniel is now extinct but was then common in the border country. Majoribanks 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-colored 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 Majoribanks' 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 Majoribanks' goals.
Golden Retrievers were first accepted for registration by the
The Kennel Club of England in 1903, as Flat Coats - Golden. They were first exhibited in 1908, and in 1911 were recognized 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 Honorable Archie Majoribanks 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 recognized the breed in 1925, and in 1938 the Golden Retriever Club of America was formed.

Health

The median life span for Golden Retrievers is approximately 10 to 12 years. They do very well in small living areas at least 500 sq. feet. While the breed is recognized for its vitality, many retrievers are susceptible to specific ailments. A responsible breeder will proactively minimize the risk of illness by having the health of dogs in breeding pairs professionally assessed and selected on the basis of complementary traits.
Breeding Golden Retrievers can be profitable for
puppy mills and backyard breeders. As a result of careless breeding for profit, Goldens are prone to genetic disorders and other diseases. Hip dysplasia is very common in the breed; when buying a puppy in the US the parents should be examined by the OFA or by PennHIP for hip disease.

Common diseases

Cancer, the most common being hemangiosarcoma, followed by lymphosarcoma, mast cell tumor, and osteosarcoma. Cancer was the cause of death for 61.8% of Goldens according to a 1998 health study conducted by the Golden Retriever Club of America, making it the breed's biggest killer.
Hip and elbow dysplasia.
Eye diseases, including
cataracts (the most common eye disease in Goldens), progressive retinal atrophy, glaucoma, distichiasis, entropion, corneal dystrophy and retinal dysplasia
Heart , especially
subvalvular aortic stenosis and cardiomyopathy are major problems in this breed.
Joint diseases, including
patella luxation, osteochondritis, panosteitis, and cruciate ligament rupture
Skin diseases, with
allergies (often leading to acute moist dermatitis or "hot spots"), particularly flea allergies, being most common. Others include seborrhea, sebaceous adenitis, and lick granuloma.
Haemophilia

Other diseases

The Golden Retriever's eagerness to please has made them consistent, top performers in the
obedience and agility rings. Plus with their excellent swimming ability they are great at dock jumping. Their natural retrieving ability also sees them excel in flyball and field trials.
Rescue efforts

Because of the prevalence and prominence of the breed, high demand results in many Goldens being abandoned each year by owners who can no longer care for them. Puppy mills are another source of orphan Golden Retrievers. These dogs, often old or in need of medical support, may end up in animal shelters.
In response to the numbers of orphan Goldens, volunteer organizations work to rescue, care for, and adopt abandoned Golden Retrievers. These
rescue groups usually accept dogs from owners and establish agreements with local animal shelters to ensure that dogs will be transferred to their care rather than euthanized. Once rescued, Golden Retrievers are placed in foster homes until a permanent home is found. It is common for rescue groups to screen prospective adopters to ensure that they are capable of providing a good home for the dog. Golden retriever rescue groups have utilized the world wide web to raise funds and advertise rescued Goldens to adopters. The Golden Retriever Club of America has a permanent standing committee, the National Rescue Committee.
