The Shetland Sheepdog , also known as Sheltie , is a sheepdog breed derived from the Shetland Islands. The original name of this breed is Shetland Collie, but when this caused controversy among Rough Collie breeders at the time, the name of the breed officially changed to Shetland Sheepdog . This hardworking little dog is smart, vocal, passionate and willing to please. They are very loyal to their owners and are often referred to as "shadows" because of their attachment to the family. This breed was officially recognized by The Kennel Club in 1909.
Like Shetland and Shetland sheep, Shetland Sheepdog is a strong but small breed, evolving to flourish in the midst of the harsh and harsh conditions of its harsh islands. While Sheltie still excels at grazing, today is also raised as a farm dog and a family pet.
The origin of Shetland Sheepdog is unclear but Sheltie is not a direct descendant of Collie. Instead, Sheltie is descended from a small specimen from Collie Scotland and King Charles Spaniel. They were originally small mixed dogs, often only about 8 inches tall 12 inches high on the shoulders, and it is thought that the original Shetland shepherd dogs were of the Spitz type, and crossed with Collies from mainland England. At the beginning of the 20th century, James Loggie added a small Collie Rough to the captivity, and helped establish what would become modern Shetland sheepdog.

Histori
Unlike many miniature breeds that resemble their larger counterparts, this breed is not developed only by selectively selecting Rough Collie for smaller and smaller sizes. Shetland's original shepherd dog is Spitz's dog, probably similar to modern Icelandic dogs. The dog was crossed with a land work horn brought to the islands, and then after being brought to England, it was broadly crossed with Rough Collie, and other descendants including some or all of the extinct Greenland Yakults, King Charles Spaniel (not Cavalier), Pomeranian, and maybe Border Collie. Shetland's original spitz-type shepherd dog is now extinct, has been replaced to be accompanied there by Border Collie. Shetland Sheepdog in its modern form has never been used as a working dog in Shetland, and ironically it is unusual there.
When the breed was originally introduced breeders called their Shetland Collies, which angered Rough Collie breeders, so the name was changed to Shetland Sheepdog. During the early 20th century (until the 1940s), additional crosses were made for Rough Collies to help retain the desired Rough Collie type - in fact, the first AKC Sheltie champion dam was the rugged Collie race.
The year 1909 marks Sheltie's initial recognition by the English Kennel Club, with Sheltie first listed being a woman named Badenock Rose. The first Sheltie enrolled by the American Kennel Club was "Lord Scott" in 1911.

Description
Sheltie's general appearance is a miniature Rough Collie. They are small dogs, double plated, work, agile and sturdy. Blue merle Shelties may have blue eyes or one brown eye and one blue eye, but others have dark eyes. Their expression should be vigilance with a gentle and sometimes protected nature. They are often very good with children. They lowered their tails low, only raised when alert and never carried away in the back. They are a very loyal type, sometimes protected by strangers but should not be ashamed or show clad according to the standard of breeding AKC.
Coat and color
Shelties have a double layer, which means they have two layers of feathers that make up their coats. The long, rugged guard hair rests on a thick, soft bottom layer. Hair water repellent guard, while undercoat provides relief from high and low temperatures.
The English Kennel Club describes three different colors: "tricolor, blue merle, and sable (ranging from golden through mahogany), characterized by varying amounts of white and/or chocolate." Basically, however, the blue merle dog is a dog that is genetically black, both black, white, and brown (tricolor). In the event ring, the blue star may have blue eyes; all other colors must have brown eyes.
Basic base color
- Sable Ã, - Sable is dominant over other colors. Probably pure for a sable or possibly tri-factored or bi-factored (carrying one sable gene and one tricolor or bicolour gene). "Tri-factored" sable and "shaded" sable are not interchangeable terms. A shaded dog (one with many black layers in a sable mantle) may or may not be worried or double-factor.
- Tricolor Ã, - black, white, and brown. Tricolor is more dominant than bi-black, and may carry a factor for bicolour.
- Bi-black - black and white. Bi-black is recessive. A Sheltie bi-black carries two bi-black genes; thus any dog ​​with a bi-black parent always bi-factored the color of his own mantle.
' Modified 'coat colors
Any color above may also have color modification genes. The color modification gene is the incorporation and white factorization. Merling melts the base color (sable, tricolor, or bi-black) which causes black dog hair to show a mixture of black, white, and gray hair, often with black spots.
- Blue merle - blue, white and brown. A tricolor with a merling gene. May have blue eyes.
- Blue-blue - blue and white. A bi-black with a merling gene. May have blue eyes.
- Sable merle - faded or dappled and white. Often born with dark brown dotted layers above lighter chocolates, they are usually present as faded or lighter faded or may appear as washed-up blue. Excess Sable is displayed on the breed's ring as a weasel; Therefore, blue eyes are the main mistake in AKC. Blue eyes are not blamed in the melodious version of the UKC.
Factoring in white affects the whiteness of dogs. It is difficult to say, without really breeding, whether a dog is white or not, although dogs with white skin that climb onto the stifle (the front of the hind legs) are usually considered white. Breeding two white dogs can produce white-headed color - Shelties with colored head (sable, tricolor, bi-black, or blue or sable merle) and white body. For dogs showing off, dogs that are more than 50 percent white are subject to heavy sanctions and therefore are not shown on breeding rings; they are normal in every other way.
Double merles , the product of breeding two merle Shelties together, has a very high incidence of deafness or blindness.
There have been reports of Sheltie, but many Sheltie fans agree that the cross on that particular Sheltie ancestor can produce dappled. Unacceptable colors in the event ring are rusty blue or black. The color may not fade, there are no striking white spots, and the color should not be more than 50 percent white.
Height and weight
Shelties usually weigh about 5-11 kilograms (11-24 pounds). In general, men are taller and heavier than women. The height range received may vary depending on the country and the standard used. In the United States and Canada, the breed standard states that men and women can be between 33-41 cm (13-16 inches), all other standards (Australia, New Zealand and the UK) assign men: 37Ã, cm Ã,  ± 2à , ½ cm, female: 35.5 cm  ± 2Ã,½ cm except FCI that determines females: 36Ã, cm  ± 2Ã,½ cm on the shoulder (wilt); however, some shelters can be found outside this range but not considered to actually represent breeds. Variations can be found in the litter, and the height (in the range of 40-50 cm) is above the breed standard in some lines.
Ear
In order to comply with breed standards, the Shelties ear has to bend slightly or "tip", this contributes to "the proper Sheltie expression". The ears have a third of the top to one quarter of the ear. If the dog's ear is not bent (referred to as ear prick), some owners hold it in the correct position for several weeks to several months. Wide-set (too far between) the ear is also not the desired trait, also the ears with the tip too low (referred to as the ear 'hound').
Caring
Shelties have a double layer, and often release a lot of time, no matter the season. Topcoat consists of long, straight, waterproof hair, which provides protection from cold and elements. The undercoats are short, hairy and very dense and help keep the dog warm. Mats can usually be found behind the ears, beneath the elbows on each front foot, and in hairy fur on the hind leg ("skirt"), as well as around the collar (if worn). The coat is usually spilled twice a year, often in spring and autumn. Women will also drip just before or right after delivery. Male shelties are technically fewer than females but their feathers are constantly released. Shaving these dogs is very bad for their skin and some do not regrow a large amount of hair after being shaved, a condition known as alopecia. Spay or castrate can change the texture of the mantle, making it softer, more vulnerable to webbing and even more. Shelties spill clumps that can be pulled or brushed out of the main coat, not individual hair. This makes them easier to tidy and clean up after than many smooth-haired dogs, leaving behind the loose feathers in their space.
Temperament
Shelties have a high level of intelligence. According to Dr. Stanley Coren, an expert in animal intelligence, Shetland shepherd dog is one of the brightest dogs, ranked sixth out of 132 breeds tested. His research found that the average Sheltie could understand the new command in less than five repetitions and would obey the command when it was first given 95% time or better.
Health
For the most part, Shelties are athletic and healthy. Like Rough Collie, there is a tendency toward malformations and inherited eye diseases. Each puppy must have eyes examined by a qualified animal eye doctor. Some lines may be susceptible to hypothyroidism, epilepsy, hip dysplasia, or skin allergies.
Shetland Sheepdogs has four times the risk of other dogs developing transitional cell carcinoma, bladder cancer.
Dermatomyositis can occur at the age of 4 to 6 months, and is often misdiagnosed by a general practice veterinarian as sarcoptic or demodectic mange. This disease manifests as alopecia at the top of the head, supra and suborbital areas and forearms and tail ends. If the disease progresses to its more destructive shape, it can affect the autonomic nervous system and the dog may have to be switched off. The disease is transmitted genetically and recessively, with breeders not having a clear methodology for screening unless a clear bloodline record. An in-tissue biopsy is needed to diagnose dermatomyositis definitively. Assessment of end-stage dermatomyositis is observed to be difficult or inability to swallow, even water.
Von Willebrand's disease is a congenital bleeding disorder. In Shelties, the affected dogs as a general rule can not live and do not live long. Sheltie carries type III von Willebrands, which is the heaviest of the three levels. There is a DNA test developed to find von Willebrands in Shelties. This can be done at any age, and it will give you three results: affected, carriers or unaffected. Shelties can also suffer from hypothyroidism, which is a less functioning thyroid gland. It is an autoimmune disease in which the immune system attacks the thyroid gland. Clinical symptoms include hair loss or lack of mantle, overweight, and lethargy.
Although small breeds typically do not suffer too severe from hip dysplasia, it has been identified in Shelties. Hip dysplasia occurs when the head of the femur and acetabulum do not fit together properly, often causing pain or imbalance. Hip dysplasia is considered genetic. Many breeders will have their dog's hips examined and certified by the Orthopedic Foundation for Animals.
Eyes
The two basic forms of eye disease that are inherited/defective in Shelties are Collie (CEA) eye anomalies and progressive retinal atrophy (PRA).
Collie eye anomaly: An autosomal recessive inherited trait that results in incomplete closure of embryonic fissures; seen almost exclusively in Collies, Border Collies and Shetland Sheepdogs. CEA can be detected in young puppies by an animal eye doctor. This disease involves the retina. It is always bilateral although the severity may be different (not equal) between the eyes. Other accompanying defects (anomaly of the eye) may be misplaced to show more severe manifestations of CEA. CEA is present at birth and although it can not be cured, it does not develop. CEA signs in the shelties are small, or deep eyes. That is, the severity of the disease at birth will not change throughout the life of the dog. CEA is judged to be similar to the way the hip.
CEA is genetic, inheritance is autosomal recessive, this means that even a dog that shows no phenotypic signs of the condition can be a carrier. Breeders should actively try to breed this disease by breeding only with dogs that have "clear" eyes or very low score eyes. A CEA score that is considered too high to breed may still be low enough to not affect the life of the dog. These dogs live happily and healthily as pets but should not be used for breeding. The recent development of DNA testing for CEA makes control of the disease much more likely because more breeders are taking advantage of the test.
PRA can be detected at any time but usually does not appear until the dog is about two years old. Feed dogs should be tested for genotypes for this condition before breeding and only "clear" animals should be used for breeding. PRA can occur in most dog breeds including mixed breeds. In most breeds, this is also an autosomal recessive condition, but has been found in other breeds to be autosomal dominant and sex-related in others. As the name implies, it is a progressive disease that will eventually result in total blindness. Like the CEA, the affected dog should not be raised but this dog can live happily as a pet. Currently there is no treatment for any good disease, but because both diseases (CEA and PRA) are hereditary it is possible to eliminate them using selective breeding.
Breeding
Like all dogs, Shelties should be screened for innate genetic disease before breeding. Both men and women should be tested for thyroid problems, Von Willebrands disease and brucellosis, as well as having hip rays and eyes cleaned by relevant national authorities.
Color breeding is also a problem for many beginner breeders. Certain color combinations can produce unwanted or potentially harmful results, such as the blue marriage merle to the blue merle, which can produce so-called "double merle", more likely to suffer deafness or blindness. Sable and white marriage to blue merle can result in merle sable, which is undesirable for show rings. A tri-color that is pure-to-sable (a sable and white that can produce only sable and other white), will produce only sable and white, but they will be tri-factored sable and whites (meaning they have -gene. ) There are many more breeding examples for color, so good breeders will examine color genetics before breeding. There are many different genes that contribute to different Sheltie colors, including bi genes, merling genes, sable genes, and tricolor genes.
MDR1 gene mutation
According to the College of Veterinary Medicine at Washington State University, Shetland Sheepdog, and many other herding breeds, have a risk of being born with MDR1 Gene Mutation, with about 15 percent of affected individuals. Cross-breeds are also affected. The dogs that carry Mdr1-1 share a common ancestor who experienced remarkable evolutionary success, after genetically contributing to at least nine different breeds of dogs. Because of this genetic mutation, the affected dog may exhibit sensitivity or adverse reactions to many drugs, including Acepromazine, Butorphanol, Doxorubicin, Erythromycin, Ivermectin, Loperamide, Milbemycin, Moxidectin, Rifampin, Selamectin, Vinblastine, and Vincristine.
Work life
As the name implies, Shelties can and have been used as shepherd dogs and still participate in experimental sheep dogs to this day. Shepherd dogs carry cattle from one place to another by causing fear-flocking behavior and flight. The instinct for shepherding is primarily the result of breeding. No amount of training can replace this trait.
Shelties can also be a good therapy dog ​​for those who need comfort during difficult times like natural disasters or severe illness. These breeds are rarely aggressive and tend to be good with children and are handled by them.
Activity
In their size group, this breed dominates dog agility, compliance, showmanship, flyball, tracking, and herding. Instinct and training ability can be measured in uncompetitive grazing tests. Shelties that demonstrate basic shepherding instincts can be trained to compete in trials.
