Keep in mind; most of us train dogs for our recreational purposes such as hunting or just to have a well behaved dog. Some train them for jobs such as search and detection, but hundreds of years ago, most dogs were trained because people relied on their assistance. Herders found that dogs could save them a lot of extra work; they could be used to warn people of other animals or potential assailants. We are living in an age where for most of us, dogs are pets and we just like to have them around. In many places of the world, dogs are a vital necessity.
