The dogs are sturdy, long-legged and even-haired, and use their visual prowess, intelligence and quick movement to control sheep.

[2] They were also bred to have less of an instinct to lie down than a Border Collie, standing still on their feet to make them more visible to the shepherd at long distance in the native tussock, and to run longer distances, and in some lines to be larger and more "hard nosed" to deal more easily with cattle.

These types of dogs are specifically bred and trained to work in farms to circle sheep and cattle.

They work with a strong eye, barking and nipping is discouraged in trials, but some will when more pressure is needed.

[citation needed] The breed requires an agrarian environment and are generally not intended to be kept as house pets.
