Hey, they're pack animals so it would only make sense man's best friend gets a social network too. The SNIF tag is a wireless doo-dad that clips onto Fido's collar. As he/she passes by other SNIF enabled dogs, they exchange data and record each other's presence. Everything uploads to an online site where your dog's SNIF profile exists.
More info on how SNIF tag came to be after the jump.
