LOUISVILLE, KY. (WDRB) -- They can go from man's best friend to your worst enemy in a second.  WDRB's Gilbert Corsey received a rare look at how a police K-9 unit is trained.

"I spend more time with him than probably my family," says Kentucky State Police Trooper Seth Payne.  Fetch for him and his dog Ferro is unlike the game that you might play, because when the 2-year-old German Shepherd is unleashed, he's not bringing back a bone.

He's bringing back the bad guy.

"I always have a partner in the back with me at all times," Trooper Payne says.  Together the team from the Kentucky State Police Elizabethtown post tracked Jeddo Dye.

Police say on June 2nd, Dye took a sleeping 10-year-old girl deep into the woods and tried to rape and kill her while her parents were away.  "He was in a basically a thicket of briars," Payne says.

Ferro bit down hard and ruptured an artery in Dye's leg when he refused to come out, highlighting how important K-9 units are.

Three of the four K-9 handlers have tracked down murderers this year and caught them.  The KSP K-9 unit re-launched in 2003 and has grown to 26 dogs of four different breeds.

The team ends up being called out every day, whether helping search for narcotics, missing persons, or escapees from jail.  Each dog is specialized, some trained to sniff out drugs or explosives others to find and apprehend people.

WDRB News intern Parker Collins was placed in the suspect suit so he can explain what it's like to be on the other side of an apprehension.  "It kept turning me around," Collins said, "and I could feel it chomping down and pushing me.

Ferro goes from friend to foe in a flash -- training that for a 10-year old girl, made the difference between life and death.

Dye is charged with attempted rape and attempted murder and remains in the Kentucky State Reformatory.  The young girl is said to be in good condition.
