If you start with a group of dogs that are bred as a working population of herding dogs, and you establish a breed from them, you will have a population of dogs that are more likely to have herding type behaviors.
A herding dog, also known as a stock dog or working dog, is a type of pastoral dog that either has been trained in herding or belongs to breeds developed for herding. Their ability to be trained to act on the sound of a whistle or word of command is renowned throughout the world. Collies are recommended as herding dogs.
