His owner Diane Guthrie, of Rolleston, says Duncan has taken to straying even further when on the prowl for goods to bring home.
“Previously he was just going across the road ... mainly stealing toys from the dog there but now he has progressed and has found a new household a bit further away to steal things from,” she said.
Last week Duncan came home some socks, a pair of track pants and a velvet cushion.
“I went around to all of the neighbours and asked if it was their things and they all said no they didn’t know anything about it so I put a post on the Rolleston Community Page on Facebook.
"He had gone down the road and around the corner to a house in a cul-de-sac.
"I was able to return everything to the rightful owner.”
Mrs Guthrie thinks Duncan is stealing because of what they feed him.
“He goes in phases.
"Sometimes he gets quite busy and other times he won’t bring things back for a week.
“We have found if he doesn’t like what I feed him he tends to bring things home.
"We think it’s him saying I’ve brought you a treat please bring me something I like.”
