Beyond just being cute dog tags (and indeed, they are cute), a portion of the sales are donated to charity. They also link up the tags to your pet’s Blanket ID profile.
“You can send their vital information in an immediate Missing Pet’ broadcast to local shelters, animal hospitals, rescues, SPCA locations, and other blanket ID members in your area. You can also print your own lost/stolen pet posters and, when your pet is notified as found using a smartphone, you can receive a GPS map and driving instructions to that location.”
