A Successful First Mission
According to a Fox News report, an Arapahoe County Sheriff's K-9 named Rex located a missing 7-year-old girl in just 12 minutes during his first-ever tracking mission.
The Colorado child had been separated from her mom for more than two hours. The mom called the police and, thankfully, Deputy John Gray and Rex, a black Labrador, responded to the call. Once Rex was brought in, things moved quickly.
After being given the girl's shoes to pick up her scent, Rex immediately got to work and didn't waste any time following the trail. Just 12 minutes later, he led Deputy Gray to a nearby backyard where the girl was hiding.
Trained for Multiple Jobs
Rex completed his tracking training just last year, and this mission marked his first real-world test in the field. Safe to say, he passed.
But Rex's skills don't stop at tracking. He's also trained in explosives detection and therapy work, and that well-rounded training proved especially valuable in this case.
After locating the young girl-and earning a well-deserved toy reward from his handler-Rex seamlessly tapped into his training as a therapy dog, offering comfort when the girl asked to pet him. Instead of simply ending the search, he stayed by her side, providing quiet support when she needed it most.
Daily Training Makes This Possible
Moments like this are the result of lots of hard work from both Rex and his handlers.
Deputy Gray says that Rex trains every single day. For tracking, that training typically includes:
- Scent work: Learning to identify and follow a specific human scent from an item (like clothing or shoes)
- Search patterns: Practicing how to track across different terrains (grass, pavement, neighborhoods)
- Obedience and control: Responding immediately to handler commands, even in high-stress situations
- Distraction training: Staying on task despite noises, people or other animals
- Scenario-based drills: Simulating real-life searches so the dog is prepared for actual missions
All of this is practiced regularly to keep their skills sharp and reliable when it matters most.
That consistent training paid off in a big way during this first mission, and it likely made all the difference in bringing the young girl home safely.
