Daisy the Cocker Spaniel was taken in 2016 after thieves took her and three other dogs from the garden kennels they were housed in.
One of the dogs was killed after being hit by a car as it tried to escape and the two others have never been located, despite searches.
Officers were alerted that someone had tried to update her microchip details, with the new owners unaware that Daisy was stolen.
Daisy was reunited with her family and “she recognised them immediately and stuck to them like glue!”.
