Dog breed
The Rough Collie or Long-Haired Collie is a British breed of long-coated herding dog of medium to large size. It is identical to the Smooth Collie in all respects but the length of the coat. Dogs of both breeds were bred for herding sheep in Scotland. In the twenty-first century the Rough Collie is commonly kept as a companion dog, or may be bred for showing. The recognised coat colours are sable or merle in various shades, tri-coloured or colour-headed white.
The Rough Collie is similar in appearance to the smaller Shetland Sheepdog, but a genetic link between the two breeds is not established.
Appearance: Recognized colours include:
Sable and white, where the "sable" ranges from pale tan to a mahogany
Tricolour, which is primarily black edged in tan
Merle, Blue or Sable merle, which is mottled.
Health: While Rough Collies are generally resilient and healthy, there are some health problems that can affect the breed.
Collie eye anomaly (CEA), a genetic disease which causes improper development of the eye and possible blindness, is a common ailment in the breed. More rarely, Rough Collies can be affected by progressive retinal atrophy (PRA), another genetic disease in which bilateral degeneration of the retina results in progressive vision loss culminating in blindness. Through genetic testing and careful screening program it would be theoretically possible to eradicate both of these problems in purebred lines, however, certainly in the UK, the Kennel Club does not require these tests to be done either for registration or showing. CEA is so prevalent that elimination of affected dogs except through very slow and careful breeding decisions to avoid shrinking the gene pool more than absolutely necessary. Rough Collie puppies should be screened at an early age (6–8 weeks) by a certified veterinary ophthalmologist to check for CEA. PRA has a later onset and can be detected by DNA test, but is much less widespread (in the US) than CEA. (In the UK, PRA is more common.) Note, the UK Kennel Club "Accredited Breeder Scheme" requires eye tests and recommends the genetic test for this class of members.
Canine cyclic neutropenia is a cyclic blood disorder that is usually fatal to affected puppies. The disease is also referred to as "gray collie syndrome", due to affected puppies having a pale grey, pinkish/gray or beige colouring, none of which are normal Rough Collie colours. Puppies that survive through adulthood are plagued with immune disorders throughout their lives and rarely live more than three years. DNA testing can help detect carriers of the recessive gene that causes the disease.
Hip dysplasia: As with most of the larger breeds, hip dysplasia is a potential concern for Rough Collies. Although this disease appears to be "multigene", careful selection by many breeders is reducing this problem. The UK Kennel Club "Accredited Breeder Scheme" requires hip-scores this class of members, however, a very small proportion of UK registered puppies are bred under this scheme. Hip dysplasia is rare in collies compared to their closest relatives and other breeds of the same size.Rough Collies may carry a mutant Mdr1 gene that results in a sensitivity to ivermectin and related drugs. A screening test is used to determine if alternative medications are required. Overdoses from the proscribed medications can result in neurological impairment or even death, but preventative doses are usually safe. This faulty gene is present in several breeds, but is well known among collies.
In addition to these problems, all of which can be tested for, there are a number of problems which are thought to be genetic but for which no screening test exists. These include epilepsy, bloat, a tendency towards allergies, and thyroid disorders (primarily hypothyroidism.). Because no DNA tests exist for these disorders (and all can have causes other than genetic origins), breeders can only do their best to avoid producing them by removing affected dogs from the gene pool.
History: Both the Rough and the Smooth Collie descend from a localised variety of herding dog originating in Scotland and Wales. The Scottish variety was a large, strong, aggressive dog, bred to herd highland sheep. The Welsh variety was small and nimble, domesticated and friendly, and also herded goats. When the English saw these dogs at the Birmingham market, they interbred them with their own variety of sheepdogs, producing a mixture of short- and long-haired varieties. After the Industrial Revolution, dog ownership became fashionable, and these early collies were believed to have been crossed with the Borzoi (Russian Wolfhound) to get a more "noble" head (longer muzzle), which is today one of the true characteristics of the Rough Collie. It is not known conclusively if the Borzoi cross made it into the mainstream of the breed.
When Queen Victoria acquired a Rough Collie, after seeing one at Balmoral Castle, they were transformed into something of a fashion item. Continued breeding for show purposes drastically changed the appearance of the dogs; in the 1960s, it was a much taller dog than it is today (in the UK; in the US, the size standard has not been revised downward and dogs have remained between 24 and 26"). Earlier dogs were also more sturdy in build and reportedly capable of covering up to 100 miles in one day. In the UK the Rough Collie is no longer used for serious herding, having been replaced by the Border Collie, though in the United States and a number of European countries, there has been a resurgence in the use of the Collie as a working and performance dog.
The Collie Club of America is one of the oldest breed-specific clubs in existence in the United States (founded in 1886). The Collie Club in England dates from 1881.
