A stray dog just a day from being euthanized was rescued and is now fighting crime.Looking at Sadie now, you’d never know how close she came to meeting her end. Sadie was at the Clermont County Humane Society and her time was running out when the Cincinnati Lab Rescue stepped in and gave her a new life.“I remember her coming into our care as a very depressed and sad dog but we knew that she was going to have another purpose in life,” Erin Skie, executive director for Cincinnati Lab Rescue told WLWT’s Erik Zarnitz.After rehabilitating Sadie, the volunteers at Cincinnati Lab Rescue noticed that Sadie had an intense focus, or perhaps more of a borderline craze, for tennis balls. As it turns out, that was a perfect personality trait for an opening on the force.Doug Eldridge worked as a drug dog handler and police officer at CVG for over 20 years.While retired, he still gets called up when a dog with the right stuff comes along.“When we are looking for dogs to train for the program, we are looking for a really high-drive ball-crazy dog. And just to watch her... she is so funny, because immediately when she comes out of the car she wants to go to work,” Eldridge said. “The whole idea of finding narcotics, from a dogs perspective is, ‘It's a game, it's fun.’ It's like hide and seek, ‘It's out there, my job is to find it and get rewarded in the process.’”Sadie is now a passive response dog. She pulls her handler, then sits to show that she’s found something illegal.When Sadie isn't working, she can usually be found playing with her ball or relaxing with her new family.
