It is compulsory for dogs to be fitted with a microchip by the time they are 8 weeks old. You are responsible for keeping your dogs microchip information up to date.

You should ask for proof a microchip has been fitted before buying a puppy or dog. You can ask to see any of the following as proof:

  • microchip certificate
  •  vet records
  •  pet passport

You must make sure the microchip details are updated once you have bought a puppy or dog.


We strongly recommend the microchipping of all pet cats as a permanent method of identification. This is often the only way we are able to find owners of cats that have been brought to us after straying or being involved in an accident.

How do microchips work?

  1. The microchips used are about the size of a grain of rice. They contain a unique identity code.
  2. The chips can be implanted under the skin by a vet or a veterinary nurse in the same way that a vaccination is given. Pets do not need a sedative or anaesthetic to have a microchip implanted.
  3. A scanner is used to detect the microchip (quite like the way the barcodes are read at supermarket checkouts)
  4. The owner’s details, including contact phone numbers, are recorded on a secure database matching the microchip number of the pet. The database is accessible 24 hours a day.
  5. The details of the scanned chip are checked against the database and the registered owner of the pet can then be contacted.

Scanners are routinely used by veterinary surgeries, dog wardens and rescue organisations such as the RSPCA all over the country.

Microchipping is included free of charge for all cats and dogs on our Pet Care Plan discount scheme.
