Koolies are herding dogs that have existed in Australia since the early 1800's. Despite this history, the Koolie is not currently recognized by any kennel club.
  
     Koolies are medium dogs that vary in coat type and color. Their coat is smooth and either short or medium in length, rarely even longer coats occur. Colors range from merle, red, or black, and often are either tri or bicolor. Large amount of white fur is undesirable, and blue eyes are preferred. Koolies resemble a cross between a Border Collie and a Kelpie, dogs they share a common "collie" ancestry with.
   
    It is believed that the Koolie has descended from the same Collie type dogs that were used to originate the Australian Cattle Dog. Many believe the Koolie has existed for longer than the ACD. They have never been recognized as a breed, simply because it was, and is, a working dog. Breeders had no desire to have them bred for looks instead of talents. It was not until the breed became more scarce that the need arose for a breeding registry. In 2000 the Koolie Club of Australia was formed, helping to meet that need and to ensure the Koolie will not meet with extinction.
  
     The Koolie is first and foremost a working farm dog. Farmers and stockmen have selected breeds to help them with their tasks. The temperament found in these dogs is exactly what these farmers have sought after, having working abilities and bonding well with their owners. Koolies are intelligent animals and experienced handlers know they need guidance and praise for their qualities to show through. They show diligence in varied roles and are patient, dedicated, and show a strong willingness for devotion. Koolies do well with children and other pets, although some individuals can be dominating.
  
     Koolies have very few health problems. Dogs with excessive white coloring may experience hearing and sight problems due to a recessive gene. Koolies can live 15 years and beyond.
