Microchips, collars and tags
The law says you must get your dog microchipped. Breeders must microchip puppies before they are sold at eight weeks.
If you sell or re-home your dog, or change address, you must update the details on the microchip database.
By law, you must ensure your dog wears a collar with the name and address of the owner inscribed on it, or on a plate or badge attached to it. A telephone number is optional but always advised.
