Reporting microchip failures
Microchips are reliable and safe, but they do occasionally fail to work.
From 24 February 2015 anyone who finds that an implanted microchip has failed or has moved from where it was implanted, or where a microchip has caused any abnormal reaction in the animal, must report it to the microchip adverse event reporting scheme run by the Veterinary Medicines Directorate. Pet owners or keepers can seek advice from their vets.
