Herding dog

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.

All herding behavior is modified predatory behavior. Through selective breeding, humans have been able to minimize the dog's natural inclination to treat cattle and sheep as prey while simultaneously maintaining the dog's hunting skills, thereby creating an effective herding dog.

Dogs can work other animals in a variety of ways. Some breeds, such as the Australian Cattle Dog, typically nip at the heels of animals (for this reason they are called heelers) and the Cardigan Welsh Corgi and the Pembroke Welsh Corgi were historically used in a similar fashion in the cattle droves that moved cattle from Wales to the Smithfield Meat Market in London but are rarely used for herding today.

Other breeds, notably the Border Collie, get in front of the animals and use what is called strong eye to stare down the animals; they are known as headers. The headers or fetching dogs keep in a group. They consistently go to the front or head of the animals to turn or stop the animal's movement. The heelers or driving dogs keep pushing the animals forward. Typically, they stay behind the herd. The Australian Kelpie and Australian Koolie use both these methods and also run along the backs of sheep so are said to head, heel, and back. Other types such as the Australian Shepherd, English Shepherd and Welsh Sheepdog are moderate to loose eyed, working more independently. The New Zealand Huntaway uses its loud, deep bark to muster mobs of sheep. Belgian Shepherds, German Shepherd Dogs and Briards are historically tending dogs, who act as a "living fence," guiding large flocks of sheep to graze while preventing them from eating valuable crops and wandering onto roads.
