Discovery Offers Potential Benefits for Dogs and their Owners
ROCKVILLE, Md., June 23 /PRNewswire/ -- 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.
"This exciting breakthrough, made possible by working with leaders in canine genetics, is helping us piece together the canine genome puzzle which will ultimately translate into potential benefit for dogs and their owners," said study co-author Paul G. Jones, PhD, a Mars Veterinary(TM) genetics researcher at the Waltham(R) Centre for Pet Nutrition -- part of Mars(R) Incorporated, a world leader in pet care that has been studying canine genetic science for the past eight years. "By applying this research approach, we may be able to decipher how genes contribute to physical or behavioral traits that affect many breeds."
Dogs originally derived from the wolf more than 15,000 years ago -- a
blink of the eye in evolutionary terms. Selective breeding produced dogs
with physical and behavioral traits that were well suited to the needs or
desires of their human owners, such as herding or hunting ability, coat
