The dog owners were strolling with Toby, their new Labrador retriever mix, near railroad tracks in Elk River when a train horn suddenly blasted.
The sound startled the skittish rescue dog. He jerked the retractable leash from their hands and "took off like a little rocket," said owner Jen Lehman, who trailed him for the next day and a half without success.
While posting Toby's description online, Lehman and her partner learned about the Retrievers, a Twin Cities-based nonprofit dedicated to helping owners find their lost dogs free of charge.
They completed a form and got a call from Natalie Wicker, a Retrievers case manager from Hugo. The search continued for another month, guided by Wicker, until a terrified Toby was captured during a late-night stakeout.
"This was all foreign territory to us," Lehman said. "[The Retrievers] were absolutely unbelievable."
The nonprofit was started in spring of 2014 by four longtime volunteers with a dog rescue organization. The group became experts in what to do when a pet ran away, but realized the public didn't know how to respond when it happened, said Devon Thomas Treadwell, a founder.
"You can be so helpful if you're prepared," Treadwell said.
In their first year, the Retrievers took on 200 cases. By sharing advice and using high-tech tools, they found the lost dogs in about two-thirds of cases, Treadwell said.
