The Koolie (also known as the Australian Koolie or by the historic misnomer "German Coolie") is an Australian dog breed. The Koolie is a working or herding dog which has existed in Australia since the early 19th century when it was bred from imported British working dogs. Robert Kaleski, in an article on Cattle Dogs in the August 1903 issue of the Agricultural Gazette of New South Wales, describes the "Welsh heeler or merle, erroneously known as the German collie," as a "blue gray dog about the size and build of a smooth haired collie, generally with wall eyes." The British background predominated in the dogs that came to be associated with the "German collie" name. There is substantial variation in the Koolie population, as Koolies were bred to exhibit different characteristics in different regions. The breed is based on its ability to work rather than on its conformation. However, most Koolie breeders refer to the Koolie as a breed rather than as a type, and assert that it "breeds true", with various types or strains. The Koolie is a "herding dog", one which has a natural instinct to circle widely round sheep and bring them back to their owner. Koolies are known as silent, upright, working dogs. They are used for herding sheep and also for quiet careful work at close quarters at lambing time or for "shedding" (cutting out) sheep. With the demand for farming dogs no longer being what it was, the Koolie has proven its worth in many other fields where it is renowned for its sensitivity, athleticism and obedience, excelling in agility, tracking, therapy, disability & emotional support service, and as the ultimate outdoor & family companion, providing they are well trained.

The Koolie is as diverse as the country it originates from, Australia. In the north of Queensland and New South Wales they are tall, medium boned and agile, bred for mustering cattle over many miles. In New South Wales, they are thicker set and shorter to flush low lying cattle from the dense bush and gullies. In Victoria, one finds the smallest variety of the Koolie, primarily used for sheep. Koolies are bred to meet the needs of the stockman, grazier and farmer; all agile, all with the same ability to adapt to any situation, all with a strong willingness drive. Male Koolies stand between 17 and 20 inches (43 to 51 cm) tall at the shoulder, while females typically measure slightly smaller, ranging from 16 to 19 inches (41 to 48 cm). Most often, they are seen in the merle coat pattern, but can exhibit any combination of colour and coat lengths. The solid red or black Koolie are often mistaken for Kelpies, and some bi coloured Koolie have been taken for Border Collies by the general public. As all of these breeds share Collie ancestry, they resemble each other. Their ears are loose and rectangular, but when the dog concentrates, they will stand erect. The Koolie coat comes in a number of variants, short and smooth like the original Scottish blue merle Collies, long like the Border Collie, short like the working Kelpie,  and medium in size like the German Tiger.

The Koolie coat ranges from short/smooth (like that of the original blue merle Collies from Scotland), short (like a working Kelpie), medium and, not common, long (like the show Border Collie). Koolies are typically slightly longer than tall. The majority of owners prefer the short/smooth coats as they do not pick up grass seed, and are very easy to maintain, with the occasional swim to keep the coat glossy and free of parasites.

Koolie colours are classed as Solid or Merle. A Solid does not show any Merle pattern, and can come in any colour such as all one colour black, red, chocolate, cream, dilute red (lilac), dilute black (blue), with tan points, black & white, dilute & white or red & white, or "Tri" solid red or black, with white markings, normally with brown points. Any of these can then have the Merle pattern i. e. usually with large splashes of darker colourings of red/chocolate for red merles or black/grey for blue merles. Black Koolies will commonly have a black nose with black eyes, or tones of black including blue. Red or chocolate Koolies will commonly have a red or chocolate nose with brown eyes, or tones of brown, including yellow, and there can be combinations of both black or brown with the added blue eye/s. There are also dilute colours of slate/blue for black Koolies and lilac/fawn for red Koolies. Yellow/cream can also be displayed when the dog is homozygous recessive on the "E locus." This recessive red (also known as Australian Red in some breeds) is considered a masking gene in that it prevents the production of black coat pigment (base skin pigment remains unaffected). Because of this, it is considered a masking gene that prevents the expression of the merle gene (and some others). In 2019, many Koolie breeders took part in the research project to find a DNA test for the Merle gene, as it was believed many non Merle looking dogs could be genetically a Merle and therefore have issues when bred to a Merle. The breeding of two Merle dogs runs a high risk (in all breeds) of sight and hearing defects in the offspring. As a “solid” (dog not showing the Merle pattern) may still genetically be a Merle, it is vital to perform a full DNA Merle sequence test to determine the “lengths” of Merle in each dog so that the safest breeding practices are used.

Graziers, stockmen and dairy farmers across Australia since days long past have typically selected breeds which display the abilities required to meet their working needs. The temperament found in a Koolie is a culmination of these much sought after abilities. The optimal worker possesses a combination of working skills and bonding temperament. There are times when an uninitiated dog owner or a new enthusiast mistakes the Koolie as a shy, reserved or even a timid animal. The Koolie's temperament needs to be understood in proper context when one seeks an optimal match of skills and demeanour. Koolies are intelligent animals, and the most experienced handlers know well that they need guidance in training. A steady and supportive approach will be productive, proving the Koolie's adaptability in diverse situations when given time. Owners will be rewarded through the Koolie's diligence in varied roles such as in work situations, sporting activities, loyal service or the time honoured role of companionship. Known to be patient, temperate, dedicated, with a strong sense of willingness and devotion. They show an untiring enthusiasm for work and an admirable hardiness when the job or circumstance requires. Given their nature, it is paramount that pups are well trained for obedience and are given both mentally challenging goals as well as physical exercise.

The median longevity of Koolies is about 15 years, which is a typical lifespan for this breed. Koolies have a diverse but small gene pool and can suffer from the many genetic problems found in recognised breeds. Many of these problems have genetic tests currently available, but hip and elbow scoring is necessary to reduce the incidence of Hip and Elbow Dysplasia. The merle for which the Koolie is most recognised by can produce blind and/or deaf white pups, if 2 merles are bred together, so merle testing should be performed prior to breeding. The Australian Koolie Association is the only Koolie breed registry which has mandatory DNA breed ID testing before a dog of unverified breeding can be registered and also requires all stud dogs to be fully health screened by DNA & hip and elbow dysplasia tested.

In 2003, DNA testing carried out on 56 individual Koolie bloodlines from Australia by Dr. Mark Neff of the University of California at Davis in the USA cleared those bloodlines tested for the presence of the mutant gene mdr1 1, which causes malfunction in the canine multidrug resistance gene; Collie bloodlines were chosen to be tested because they showed a reaction, even death, to chemicals, such as Ivermectin, used in the treatment of intestinal parasites. In 2004, the Koolie Club of Australia in conjunction with Genetic Science Service of Australia launched the collection and processing of Koolie DNA. There are several common genetic disorders that are found in the breed but which can be easily managed with safe breeding practices thanks to simple testing. The Australian Koolie Association has distinct sections for both purebreds and part bred Koolies, whereas other registries do not make this distinction.

Koolies are much sought after in rural Australia, and interest is now being shown in America, Canada, Germany, Finland, New Zealand, Switzerland and Holland. According to Geoff Broughton, past president of the Koolie Club of Australia for 7 years, the Koolie will head (move to the front or head of the stock to push them back towards you), heel or drive, (push the stock from behind), cast (move out and around the stock), block (hold the stock or block them from in front, in three sheep trials this action is called the pick up) and back (literally jump onto the backs of their charges to herd them if necessary). Koolies have a reputation for being upright workers with a good eye, who can easily shift their focus from holding the group to casting around a flock or gathering breakaways. They are not known for having "sticky eyes" (focusing on the sheep in front only). Unlike other working breeds, which are noted for their crouched form or style and preference for either yard or field work, Koolies are at ease working in closed surroundings such as yards or trucks and being out in paddocks and droving. As well as working anything from ducks to bulls, like all dogs of their kind they will herd family members and children in the absence of other charges. Herding instincts and trainability can be measured at non competitive herding tests. Koolies exhibiting basic herding instincts can be trained to compete in stock dog trials.

The Koolie's ancestors were thought to be the smooth coated blue merle Collie (imported from Britain in the 19th century) and the Black and Tan Collie from the Highlands of Scotland (black and tan collies are not a breed); but dogs imported by early German settlers are believed to be descended from the "German Tiger", a European herding dog, however DNA evidence is yet to be found support this. DNA testing has found that the Australian Kelpie is the closest known relative. During the industrial era some bloodlines were influenced by Kelpie and Border Collie, as explained by one grazier in Western Australia, "You bred from the good workers which were around and Koolies were not always to be found, so you bred to the next best worker that was and this was either the Kelpie or Border depending on the region you lived and the stock you worked". Many be breeders still out cross both Kelpie and Border Collie lines, which are accepted practices with the Koolie breed registries. In 2000, the Koolie Club of Australia was formed to preserve and promote the Koolie breed. Later the Working Koolie Association & Australian Koolie Association were formed as well. None of these registries actively work towards bench standard recognition, feeling this would only be detrimental to the breeds working future. As of (2013), no bench standard exists. In 2004, the Koolie breed was recognised by the Australian Sporting Registrar, judges from the Australian National Kennel Council (ANKC) may judge Koolies in all ANKC sanctioned sporting trials. In the states of Victoria, New South Wales, and Queensland, registered Koolies may compete in, herding, obedience, tracking, jumping, gambles and dog agility events through registration on their State's Sporting Register as members of the Koolie Club of Australia or the Australian Koolie Association

In May 2006, the Stockdog Committee of the Australian Shepherd Club of America voted to accept the "Koolie/German Coolie" into their list of recognised and accepted herding breeds, admission was granted June 2006. In 2006, the American Herding Breed Association accepted the Australian Koolie onto their list of recognised and accepted breeds.
