The Kelpie is an Australian sheep dog successful at mustering and droving with little or no command guidance. They are medium-sized dogs and come in a variety of colors. Kelpies have been exported throughout the world and are used to muster livestock, primarily sheep, cattle, goats, and poultry. The breed has been separated into two distinct varieties: the show or bench Kelpie and the working Kelpie. The show Kelpie is seen at conformation dog shows in some countries and is selected for appearance rather than working instinct. Working Kelpies are bred for working ability rather than appearance. However, the Kelpie breed is often identified by a facial expression similar to a human smile.
