3. Microchipping

In April 2016 it became compulsory for all dogs to be microchipped. Dogs older than 8 weeks old and uncertified working dogs, must be microchipped if they've not already been done from that date.

The keeper of any dog which has not been microchipped may be served a notice requiring the dog to be microchipped. Where the keepers details are registered incorrectly, they may also be served a notice requiring the dog to be microchipped, or that their details are updated correctly. This must be done within 21 days. Failure to comply with the notice could result in the dog being microchipped without the consent of, and chargeable to, the keeper and/or a fine of up to £500 on conviction.


Microchips are the size of a grain of rice. They're implanted under the skin of a dog by injection, usually within the scruff of the neck. The keepers contact details are then recorded against the number of the microchip and are stored on a national database.

If a dog strays and is seized by the council, the dog is scanned for the microchip to help identify the keeper and advise them that the dog has been found. It's important to make sure that contact details are up to date with the relevant microchipping company.

The Dogs Trust offers free microchipping nationwide. Please visit the Chip My Dog website or telephone 0330 123 0334 to find your nearest participating microchipping location.

The Dog Warden Service does not offer free microchipping. Details of any upcoming microchipping events will be advertised accordingly.
