Bedlington Terrier

The Bedlington Terrier is a breed of small dog named after the mining town of Bedlington, Northumberland in North East England. Originally bred to hunt vermin in mines, the Bedlington Terrier has since been used in dog racing, numerous dog sports, as well as in conformation shows and as a companion dog. It is closely related to the Dandie Dinmont Terrier, Whippet and Otterhound.

It is described as a very versatile yet contradictory dog, being both good with children and "fit to kill any other dog of his weight". They have powerful swimming skills, comparable to those of water dogs such as the Newfoundland, and are noted for being very quick and having high endurance. Bedlingtons are noted for their similarity in appearance to lambs. The dogs have blue, liver or sandy colouration, all three of which may have tan points. Their fur forms a distinctive top knot on the dog's head.

Originally known as the Rothbury or Rodbury Terrier, the name Bedlington Terrier was not applied to the breed until 1825, but some dogs have pedigrees that can be traced back as far as 1782. The first dog shows with a class for Bedlington Terriers was held in 1870 at Bedlington. Bedlington Terriers shown at early shows were frequently dyed to improve the look of their fur. In 1948, a Bedlington Terrier known as Rock Ridge Night Rocket won best in show at the Westminster Kennel Club Dog Show. The breed has a high instance of copper toxicosis, but with the exception of eye problems, it is mostly free from health complaints.

Description

Appearance

The Bedlington Terrier has been described as resembling a lamb. It has also been compared to a miniature version of the Scottish Deerhound. George Shields stated that exceedingly well-bred dogs possess the spirit of a thoroughbred racehorse.

The dogs have blue, liver or sandy colouration, all three of which may have tan points. Bedlingtons carry what is known as the greying gene, a dominant trait carried on the G locus. This gene causes puppies born with black or dark brown fur to lighten to grey or liver with age. The fur of the Bedlington creates a shape on the top of the dog's head known as a topknot. Although most modern breed standards call for the dog's topknot to be lighter than its body, when the breed was first being formed there was at least one prominent breeder, Mr. Pickett, who believed that the topknot should be darker, not lighter.

The dog's coat has been described as shaggy, hard, and rugged in style and it has also been described as linty in texture, giving the breed the nickname of "linty-haired terrier". Its coat is made up of a combination of hard and soft hairs. It is extremely difficult to maintain a "show clip", even for professionals, and grooming can be quite expensive.  Dogs in what is referred to as show clip, or groomed for the show ring, cannot have fur that stands out more than 1 inch (2.5 centimetres) from their body, and the coat must have a "crisp" texture. If grooming is not performed regularly, the coat's condition rapidly deteriorates. For that reason, most Bedlingtons that are kept strictly as pets keep a lower maintenance "pet groom" style. Bedlington Terriers have been referred to as a nonshedding hypoallergenic breed.

The head of the dog must be rounded in shape with no stop. Their eyes are almond-shaped and small, and the lips are close-fitting and lack flews. The back must be arched, and the body should be slightly longer in length than in height. Although 16.5 inches (42 cm) is the preferred height for male dogs, a range from 16 to 17.5 inches (41 to 44 cm) is allowed; for females, the preferred height is 15.5 inches (39 cm) and the acceptable range is from 15 to 16.5 inches (38 to 42 cm). Both genders must weigh between 17 and 23 pounds (7.7 and 10.4 kg). They possess a light, springy gait.

Temperament

Bedlingtons are sharp and plucky. Their bark has been called hound-like and has been compared to the firing of a machine gun.[4] Fast dogs with high endurance, the Bedlington Terrier is just as quick in water as it is on land, and their swimming speed rivals that of the Newfoundland. Bedlington Terriers "have pace enough to keep up with the ordinary speed of a horse." Because of the Whippet in their lineage, they have a tendency to bolt. Their versatility has been praised, with some dogs willing to " a house-dog, a gun-dog, a rat-dog, a badger-dog, or, if needed,  bolt a fox..."

They are also known for their intelligence and tenacity when it comes to taking on vermin. Bedlingtons are quite fond of fighting, and are prone to jealousy when around other dogs. One man stated that "this dog was about fit to kill any other dog of his weight" and compared him to the fighting dogs used in dog fighting. They have also been used in pit fighting.

However, both the AKC and the ASPCA call the breed "mild" and "gentle" and recommends it as being good with children. PetFinder says the breed is soft in temperament, companionable, demonstrative, loyal, and a quiet housedog. Although the breed may chase small animals outside, it is accepting of them inside. Playful and cheerful, the breed can be high-strung and excitable, and is prone to being headstrong. The New Zealand Kennel Club warns against keeping them with dogs that have dominant personalities, "as once challenged they are terrifying fighters, despite their gentle appearance", but otherwise the breed is good with other dogs.

Some breeders, notably George Newcombe, have argued that the working ability and courage of the Bedlington terrier has declined since it began being bred for show. Poodle may have been introduced into the breed to make the coat easier to groom and maintain. George Newcombe of the Working Bedlington Terrier Club said that "the pure  could no longer be considered a serious working breed" and proceeded to cross his dogs with Lakeland Terriers in an attempt to bring back the Bedlington's working qualities.

Health

Longevity

Median longevity of Bedlington Terriers, based on two recent UK surveys, is about 13.5 years, which is longer than for purebred dogs in general and longer than most breeds similar in size. The longest-lived of 48 deceased dogs in a 2004 UK Kennel Club survey was 18.4 years. Leading causes of death among Bedlington Terriers in the UK were old age (23%), urologic (15%), and hepatic (12.5%). The leading "hepatic" cause of death was copper toxicosis. Dogs that died of liver diseases usually died at a younger age than dogs dying of most other causes.

Bedlington Terrier owners in the UK reported that the most common health issues among living dogs were reproductive, heart murmur, and eye problems such as epiphora, retinal dysplasia, and cataracts. Bedlingtons seem to be more prone to these eye diseases than other breeds. They also have a high incidence of kidney problems. Copper toxicosis occurred among about 5% of living dogs. Inbreeding is a concern, as some dogs " been bred in and in to a damaging extent."  Reputable breeders will conduct DNA testing of all litters and will not allow pups who carry the copper toxicosis gene to be bred, a practice which has significantly reduced the incidence of this disease in the breed. Excepting these problems, Bedlingtons are generally a very healthy breed.

Copper toxicosis

Copper toxicosis, also known as copper storage disease and copper overload syndrome, is an autosomal recessive disease that is characterized by an accumulation of copper in the liver. It is closely related to Wilson's disease in humans. Bedlington Terriers are more prone to copper toxicosis than most other dog breeds. West Highland White Terriers, Skye Terriers, and Doberman Pinschers are also prone to copper storage disease. Bedlington Terriers are the only breed of dog in which haemolysis has been reported, but there have been no reports of neurological involvement in any dog breed. Studies have shown that in Bedlingtons, the disease is caused by a defective metallothionein that causes cell lysosomes to become saturated with copper. This causes the cell to store copper in the nucleus. There are three varieties of the disease: the Asymptomatic Form occurs when copper accumulates but there are no clinical symptoms of the disorder; the Fulminating Form which is seen mostly in young dogs, causes death in two to three days, and is thought to be caused by stress; and the Chronic Form, which is characterized by an extended period of time in which liver disease slowly causes the death of the dog. Bedlingtons also have a tendency to accumulate iron in the liver, but not nearly to the extent that they accumulate copper.
