Dogs come in such a wide variety of shapes, sizes, and breeds, it s hard to believe that they all have a common ancestor the wolf! Told through the eyes of a lone wolf pup and the prehistoric boy he befriends, we see how the bond between our ancestors and these wild animals formerly enemies may have developed. Initially, the two species discovered that they each had the ability to provide the other with food, protection, and security. Over the years, the wolves that chose a life with humans became more domesticated, and varied in their talents, and were bred for specific traits such as hunting, herding, pulling, and rescuing. Today there are more breeds of dog than of any other animal, all thanks to the unbreakable friendship that s formed between dogs and humans.
