Microchipping pets
Quick answer
UK dog owners must **microchip their dog by 8 weeks** and keep database details up to date. Cats are increasingly covered by UK law too. A microchip is not a GPS tracker — it identifies your pet when scanned by a vet or rescue centre.
Key takeaways
- Contact the UK database your chip is registered with — not the chip maker. Update phone numbers and address whenever you move. Out-of-date details are the main reason lost pets are not reunited.
- A trained veterinary professional or qualified implanter. The BVA recommends chips linked to a UK-compliant database and implanted under veterinary supervision.
