A Woodstock family, who had given up hope they’d ever see their beloved dog again after he went missing six months ago, now has him back thanks to social media.

Danny and Diana Prince were heartbroken when their 9-year-old golden lab-mix Duncan escaped during a thunderstorm on March 9. After searching for days, they were contacted by Lara Shaw from Angels Among Us Pet Rescue offering to help. Besides putting up signs and trail cams, she took to searching missing pet pages on social media and last week spotted a post that looked like Duncan.

“I kept zooming in and I saw the collar and it was red on the side; and I tagged Danny and Diana and I said I think that it’s worth a shot to go up there because I think it looks like Duncan,” Shaw tells WSB’s Sandra Parrish.

The couple traveled to the poster’s home in Canton, some eight miles away, with McDonald’s hamburgers in hand.

“We all of the sudden saw a tan-colored animal and we kept calling for his name… And he came up and ate the hamburgers and then came to us. We realized when he was responding to his name—it was Duncan,” says Diana.

Duncan had lost nearly half his body weight—going from around 75 pounds down to 40. But otherwise, he was healthy.

Danny wonders what path he would have taken to end up in Canton.

“We’re not for sure if he followed the highway through the woods. Just the place where he was at, was not what we were expecting,” he says.

Shaw says eight miles isn’t that unusual and, in fact, has seen a dog travel up to 35 miles away before being found.

Diana says it’s a lesson in using the resources you have and never giving up.

“Sometimes it’s easier emotionally just to write it off and be done. That’s what we did, and we ended up being proved wrong. They can still be out there. Just keep trying and keep looking for them,” she says.

Shaw hopes the message gives others with missing pets hope.

She is currently working the case of another missing dog, Bailey, who disappeared from her Cobb County home last month after her owner died unexpectedly. A dedicated group of friends, including Shaw, is continuing the search for her.
