This looks like any other ordinary dog tag, but there is a catch - it comes with 512MB of flash memory which you can use to store some information, although I would avoid having mission critical and personal information inside. Shaped after a doggie bone, each of these USB flash drives/dog tag hybrids come with a silicone texture that dogs go crazy over when chewing them. It retails for approximately $25 a pop after conversion. Looks like a good gift idea when you're dropping by a friend's apartment who happens to rear one of these four-legged creatures.
