A family from Bristol have been reunited with their pet Staffordshire Bull Terrier after a friend spotted him for sale on Facebook.
Cotton was taken from the family home four years ago during a burglary.
Speaking to the BBC, owner Joanna Martin described the moment she saw the dog again: "I called his name and he just got over-excited, he was bouncing everywhere. I burst into tears."
A woman has now been arrested on suspicion of handling stolen goods.
