For years, owners have been able to get dogs tested to prove they are the offspring of parents that breeders said they were. In the new testing, DNA markers that help tell breeds apart are checked against the thousands of DNA samples to find out Fido's ancestry.
A new test unveiled late last month by Virginia-based Mars Veterinary uses DNA from blood samples taken by veterinarians and sent to a lab in Lincoln. Within four to six weeks the genetic puzzle is solved for the dogs' owners.
The method can test for 134 of the 157 dog breeds recognized by the American Kennel Club. The company plans to have data for all the breeds by the end of this year, said Paul Jones, a scientist in England who led the method's development.
