From the 6 April 2016 all dogs in England must be microchipped.

After this date, any owners of dogs found by the police or local authorities without a microchip will be given a short period to comply with the microchipping law. If they do not, they may face a fine of up to £500.

In collaboration with the Microchip Trade Association (MTA) the Veterinary Medicines Directorate (VMD) set up a monitoring scheme to oversee reports of potential adverse events following microchipping.

The VMD does not regulate the animal microchip market, but in view of its existing reporting scheme for veterinary medicines and the need for impartiality, the VMD has taken on this role.

Information covered includes:

  • what adverse events might be seen following microchipping
  • how to report a suspected adverse event involving a microchip
  • why microchips are used
  • how a microchip works
  • who is running this scheme and its purpose
