Former Spice Girl Emma Bunton made an emotional plea and offered a reward for the safe return of her "beloved" chocolate brown Labrador after the dog went missing.
Phoebe, described as a "gentle" dog who is microchipped, went missing on Monday during a walk on Hadley Wood Common in north London.
Bunton has appealed to her Twitter followers for help finding her pet and said she was "in bits" after the dog's disappearance.
