SNIF Tags offer a small RFID chip that attaches to your dog's collar, where you can then log in to their online site and see your dog's activity level while you are away from home. While it doesn't provide any GPS locating, and certainly would not serve as a microchip for international pet transportation purposes, it does tell you when your dog is up walking around or lying down.One of the cooler features that it offers is the social networking tool -- dog owners can create profiles for their pets and if you bump into another pet with a SNIF Tag on out on a walk or in a dog park, it will show that the two tags "connected" on the two dogs' profiles.
