What makes a pointer point, a sheep dog herd, and a retriever retrieve? Why do Yorkshire terriers live longer than Great Danes? And how can a tiny Chihuahua possibly be related to a Great Dane?

Dogs vary in size, shape, color, coat length and behavior more than any other animal and until now, this variance has largely been unexplained. Now, scientists have developed a method to identify the genetic basis for this diversity that may have far-reaching benefits for dogs and their owners.

In the cover story of tomorrow’s edition of the science journal Genetics, research reveals locations in a dog’s DNA that contain genes that scientists believe contribute to differences in body and skull shape, weight, fur color and length — and possibly even behavior, trainability and longevity.
