Microchip does not match the registration on the database!

Thought this might be of interest, this dog was missing and has now been reunited but very worrying comment by the owner re microchip.
 Thank you very much to the person that found her. A word of warning, her Micro chip which had been professionally inserted by a vet practice did not correspond to the dog. The chip she has is correct (scanned by our sheep scanner) but relates to a dog in KENT. So not a lot of use had she been stolen and identified elsewhere!
