Tiana Vignola's beloved pooch Louie went missing from a house in Oakdale in August 2019.
A boy in Port Jefferson found Louie in the road on Tuesday.
A good Samaritan couple took the dog from the boy and brought Louie to Save a Pet Animal Shelter in Port Jefferson Station.
They scanned him for a microchip and up came Vignola's number.
Vignola, of Southampton, says Louie appears to be in great health and is happy to be home.
