About 20 bloodhounds from across the country are in the Triad this week working to earn certification. Dogs and their handlers are receiving training from the National Police Bloodhound Association. Greensboro K-9 officer J.D. Fraser works with four-legged partner Ellie Mae. She is trained to assist in missing person searches. Officer Fraser says the re-certification process hones Ellie Mae's skills and gives credibility to the practice.
