Greensboro, NC -- The Greensboro Police Department is hosting the National Police Bloodhound Association for the fourth consecutive year.
The department expects 30 bloodhounds, along with their handlers, to participate in the week-long event, which started Sunday.
The event includes classroom instruction, practical exercises, and a certification course.
Teams will be evaluated throughout the week by a certified trainer. They will also have to complete field work, a written exam and documentation of record keeping.
The certification only lasts a year.
The Greensboro Police Department has two bloodhound teams to help track lost or missing persons, as well as assist in criminal investigations.
Sgt. RL Walton and Canine Bocephus, or "Bo," (left) have been partners twice in their careers. Bo was donated to the department by a local family when he was 10 months old. He's now 4 years old and has helped locate missing persons, robbery suspects and one suicidal person.
Officer MP O'Hal and Elli-Mae (right) have been together since the spring of 2012. Ellie-Mae, also four, was donated by a wildlife officer when she was a puppy. Together, O'Hal and Ellie-Mae have found missing children, Alzheimer's patients, and several criminals.
