It's a legal requirement for all dogs over the age of eight weeks to be microchipped
All dogs over the age of eight weeks must be microchipped and their registered details must be kept up to date. Microchipping your pet gives them the best chance of being identified and returned to you if they become lost or stolen.
Dogs Trust are currently offering free microchipping and advice on responsible dog ownership as a part of their community events programme.
Updating your dog's microchip
If you move or change your telephone number it is important to tell the microchip company so they can update their records. You will also need to arrange for the details on your dog's microchip to be changed if your dog is sold or given to a new owner.
Contact the vet or organisation that inserted the chip to update the details (please note that there may be a charge for this). If you don't know who microchipped your dog, a vet can check this for you.
