The human-canine connection represents a unique interspecies bond. Since the domestication of dogs from their wolf ancestors between 11,000 and 16,000 years ago, dogs have had a major impact on our development as a species. They have played a wide variety of roles in our lives, acting as guide dogs, sled dogs, hunting dogs, herding dogs, drug dogs, rescue dogs, therapy dogs- you name it.
