The New Zealand Heading Dog is a New Zealand breed of working and herding dog derived from the Border Collie. The dogs are sturdy, long-legged and even-haired, and use their visual prowess, intelligence and quick movement to control sheep. They are generally black and white in colour, but may also be tan.
