Common Questions


No, currently it is only compulsory to have your dog MicroChipped. If your dog is over 8 weeks of age then it must be MicroChipped and registered on a compliant UK MicroChip Database.

Firstly, it's really important that you do update the details to ensure that we can always contact you if your pet is found.

Secondly, there is more than one database in the UK for MicroChipped pets. For this reason it is advisable to have your pet's MicroChip number to hand before contacting us regarding your pet as it will enable us to help you more easily.

For a change of address you may update via the telephone, online and in writing.

A change of keeper will only be accepted in writing for security reason. We have procedures in place to ensure that a transfer is legitimate and to try and prevent transfers when a pet is missing or has been stolen. Even if you do not have contact with the previous keeper, we will be able to handle this once the application form is received.

The MicroChip database is an integral part of helping to reunite lost and stolen pets, alongside the microchip identification products (the pet microchips & scanners).

24 hrs a day, 365 days a year our database service is there to help reunite lost pets - trained personnel, online services, SMS services and mobile apps all provide this dedicated service.

As well as providing this service for pet owners the MicroChip database also works alongside veterinary practices, rescue centres, animal wardens and microchip implanters.

There is a cost in providing, maintaining and developing the database service which we operate, particularly manning the database 24 hours a day.

You might be surprised to learn that we receive no government funding for providing this service.

The price paid at the time of having the MicroChip implanted is for paying to have it implanted and for the MicroChip itself. Only a very small proportion of this money is used by the database service.

It is also important to remember that we want to provide a database service for the entirity of your pet's life and not just this year or the next - the charges we make help to ensure this happens.

We understand that some pet owners will need to update details more frequently than others which is why we offer the option to upgrade to PETtrac Plus - for more details click here.

The AVID MicroChip is a tiny computer chip which has an identification number programmed into it. The chip is encased in a strong bio-compatible glass, and is small enough to fit into a hypodermic needle. Once the chip has been implanted, the unique number can identify your pet throughout their life once registered on the PETtrac Database. The MicroChip is covered in an anti-migratory coating to help prevent the MicroChip moving.

A special scanner is used to send a radio signal through the skin of the animal to read the chip. The animal feels nothing as the scanner is passed over him and the chip is read. The MicroChip number is then relayed to the scanner where it is displayed.

No, the MicroChips are not GPS tracking devices. They are scanned with a special handheld scanner. The MicroChip number is displayed on the scanner and the authorised authorities use these number to identify you and your pet.

Currently, the technology does not exist to manufacture an implantable GPS pet MicroChip but there are devices which will attach to your pet's collar to provide this service.

Your pet does not need a collar tag to say that they are MicroChipped, but many pet owners like to have them as it alerts a member of the public who finds your pet that they should be taken to be scanned.

For dogs it is a legal requirement for them to wear a collar tag under the Control of Dogs Order (1992). For more information on the engraved brass collar tags we offer which also state that a pet is microchipped please click here.
