The New Zealand Heading Dog is a working and herding dog that uses its visual prowess, intelligence and quick movement to control sheep. Bred from Border Collies, Heading Dogs are a sturdy, long-legged and even-haired breed. They are generally black and white in color, but may also be tan. New Zealand Heading Dogs are very aware of their surroundings and are able to adapt to quick movements that are in their line of sight, suiting their shepherding requirements, and are able to run long distances day after day. 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. They are medium to large dogs with smooth, straight hair.
