The Control of Dogs Order 1992 legally requires that any dog in a public place must wear a collar with the name and address (including postcode) of the owner inscribed on it, or engraved on a tag attached to the collar. The telephone number of the owner is optional. Fines of up to £5000 can be incurred if your dog does not wear an identification tag.
