While dogs were the first animal to be domesticated, its origins as a species remains a mystery beyond their ancestry from wild wolves. We also know the early human relationship was as hunting partner and protector. Fast forward to today and dogs are thoroughly domesticated and have taken their place by the hearth of millions of homes while keeping us safe and in many places still helping with the hunt and protecting livestock. For most of us, however, a dog is a loyal companion who returns our affection freely and forever.
