Dogs as herders

From Articlemuse

Have you ever been to a ranch and watched a dog work in harmony with its owner in gathering up the sheep or cattle or other animals? Most dogs have what is called a strong defensive drive, meaning that they protect their owners from harm or danger. This is the drive that comes into play when herding; they are actually acting as a protection by moving the animals back where they belong.

This particular trait is very important and useful when it comes to herding and ranching. Dogs not only keep animals in order, they also guide them to where they're supposed to be going. They are quicker and more nimble than men on horses and so can get to straying animals quicker.

Many who own ranches or farms of any sort will attest to how important these animals are and how they really could not do their job properly without them.
