What is a microchip? 

A microchip is a small electronic chip, around the size of a grain of rice, which is implanted under the dog's skin and contains a unique number that can be read by a scanner. 

The dog owner's contact details relating to each number are logged on a central database, so should the dog ever go missing or be stolen it can be scanned by the authorities and returned to his owner swiftly and safely.

It is vital that the owner takes responsibility for updating their details with the database should their circumstances change. 

How do I update my dog's microchip details? 

It is important to remember to keep your dog’s microchip details. If you move to a new house or change your phone number, you must contact your microchip database provider to let them know.

Every year, thousands of stray dogs are unable to be reunited with their owners because their tag and chip details are not up to date. Not only it is a legal requirement to ensure that your contact details are up-to-date, but the microchip is useless without them. 

It’s simple to update the details for your dog’s microchip; you can do it online, by telephone or by post – depending on which database your chip is registered to. Charges for updating your contact details will vary across microchip database providers.
