The remarkable surge in genetic technology has now allowed us to look at dogs and dog breeds in a whole new way. We can not only determine the wild canine ancestral species from which our dogs were domesticated, but we can also determine a timeline which allows us to see how close any given breed is to the ancient primitive wolf from which our dogs evolved. We do this through something which is called a cladogram analysis of dog genes. A cladogram is a sort of evolutionary family tree, with various branches representing breeds of dogs or species of canines.
