Humans and dogs have been the closest friends for thousands and thousands of years. When humans still lived in caves, scientists speculated that wolves that had stayed closer to the caves were rewarded with food scraps. With the passing of the eons, even the wolves benefited the humans; his sense of smell and hearing woke the sleeping humans of any threatening lion or Sabertooth tiger trying to sneak in. Soon the wolves began to help their human friends during the hunt.
