This isn t a Rambo style dog tag—even though Stallone would look cute with it on—this is a high-tech version of traditional dog tags. This tag is able to store a ton of information including: name, phone numbers, addresses, e-mail addresses, medical information, favorite dog food, etc. It even comes in a variety of colors to match whatever abomination of a sweater your dog is wearing against it's own will. This is available now for $39.95.
