If your four legged friend takes pride in his appearance & appreciates the finer things in life then he'll love this unique I'm kind of a big deal name tag! If using as an ID tag in the UK the Control of Dogs Order 1992 states that any dog in a public place must wear a collar or engraved tag with the name & address (including postcode) of the owner. Your telephone number is optional but we would recommend this. The tag is 28mm in diameter & 2mm in width.
