Border Collie

Health

Lifespan
The natural life span of the Border Collie is between 9 years to 17 years, with an average lifespan of twelve years. The median longevities of breeds of similar size are usually 12 to 13 years.
Leading causes of death were cancer (23.6%), old age (17.9%) and cerebral vascular afflictions (9.4%).

Common health problems
Hip dysplasia, Collie eye anomaly (CEA), and epilepsy are considered the primary genetic diseases of concern in the breed at this time. CEA is a congenital, inherited eye disease involving the retina, choroid, and sclera that sometimes affects Border Collies. In Border Collies, it is generally a mild disease and rarely significantly impairs vision. There is now a DNA test available for CEA and, through its use, breeders can ensure that they will not produce affected pups. There are different types of hip testing available including OFA (Orthopedic Foundation for Animals) and PennHip. Radiographs are taken and sent to these organizations to determine a dog's hip and elbow quality.

Elbow dysplasia or osteochondritis, deafness, and hypothyroidism may also occur in the breed. Dogs homozygous for the merle gene are likely to have eye and/or hearing problems.

Neuronal ceroid lipofuscinosis (NCL) is a rare but serious disease that is limited to show Border Collies. NCL results in severe neurological impairment and early death; afflicted dogs rarely survive beyond two years of age. The mutation causing the form of the disease found in Border Collies was identified by Scott Melville in the laboratory of Dr. Alan Wilton of the School of Biotechnology and Biomolecular Sciences, University of New South Wales. There is no treatment or cure, but a DNA test is now available to detect carriers as well as affected dogs.

Trapped neutrophil syndrome (TNS) is an inherited autosomal recessive disease which results in mature neutrophils being unable to migrate from the bone marrow into the blood stream. Puppies affected with this disease usually succumb to infection. Because TNS is an immune deficiency, the puppies can present a variety of symptoms depending upon the type of opportunistic infections they contract; as a result, TNS has largely gone undiagnosed in the past. Once thought to be rare, TNS is now believed to be responsible for many cases of "fading puppies". The mutation responsible for TNS is also only found in show dogs, and was identified by Jeremy Shearman in the laboratory of Dr. Alan Wilton of the School of Biotechnology and Biomolecular Sciences, University of New South Wales. There is no cure, but a DNA test is now available to detect carriers as well as affected dogs.

History

Origins
The Border Collie is descended from droving and gathering breeds originating on the Scottish-English and Welsh-English borders, including the Cumberland Sheepdog. Mention of the "Collie" or "Colley" type first appeared toward the end of the nineteenth century. Many of the best Border Collies today can be traced back to a dog known as Old Hemp. Old Hemp, a tri-color dog, was born September 1893 and died May 1901. He was bred by Adam Telfer from Roy, a black and tan dog, and Meg, a black-coated, strong-eyed bitch. Hemp was a quiet, powerful dog that sheep responded to easily. Many shepherds used him for stud and Hemp's working style became the Border Collie style.

Wiston Cap is the dog that the International Sheep Dog Society (ISDS) badge portrays in the characteristic Border Collie herding pose. He was a popular stud dog in the history of the breed, and his bloodline can be seen in most bloodlines of the modern day collie. Bred by W. S. Hetherington and trained and handled by John Richardson, Cap was a biddable and good-natured dog. His bloodlines all trace back to the early registered dogs of the stud book, and to J. M. Wilson's Cap, whose occurs sixteen times within seven generations in his pedigree. Wiston Cap sired three Supreme Champions and is grand-sire of three others, one of whom was E. W. Edwards' Bill, who won the championship twice.

These dogs were traditionally known simply as "collies," but terms like working collie, old-fashioned collie, and farm collie have also been applied to them. It was in 1915 that James Reid, Secretary of the International Sheep Dog Society in the United Kingdom, first used the term "Border Collie" to distinguish those dogs registered by the ISDS from the Kennel Club's "Collie," which originally came from the same working stock but had developed a different, standardized appearance following its introduction to the show ring in 1860.
