Dogs are a domesticated sub-species of the wolf. A carnivorous animal. When you get bit you will know it. These creatures are members of the Canidae family of the order carnivora used for both feral and pet varieties. Everything I have read shows that the domesticated dog has been one of the most widely kept working and companion animals in human history. Saw somewhere there was even a Keeshound with the three wise men.

Our domestication of wolves, most think the gray wolf took place around 15,000 years ago somewhere in the central Asia region. Dogs quickly became everywhere across most cultures of the world. With the resulting domestication process, dogs have developed a sophisticated intelligence that includes unparalleled social cognition, along with a theory of mind that is important to their interaction with humans. Just love it when you come home and they wag there tails until they are silly. Their social skills have helped dogs to perform in protection of humans, hunting, animal herding and currently assisting handicapped individuals.
