The Australian Koolie breed has evolved on farms without structured breeding plans and standards from the mid 1800’s, into an elite working dog with a broad range of skills and abilities. They are physically and mentally able to work all day beside their human workmate, mustering sheep, droving cattle, loading trucks, whatever is necessary - thrilled to be able to help in any way possible. At the end of the day happy to curl up at his feet in camp, keep him company and an eye out for trouble. Because of the long history of good working dog being bred to good working dog and a diverse gene pool, they have few physical problems, are easy breeding and sound. Also due to the concentration on breeding for working ability they have evolved in a range of sizes, of coat colors, coat length and ear set, which has helped them adapt to the diverse range of jobs they take on. Ears are usually pricked but can be semi pricked or dropped. They are a medium size working breed with the occasional bigger dog and some small lighter dogs which all suite the different tasks they take on.
