Hi Ally - the one I use is Medic Alert. Here is the link for their basic collection and if you scroll down to the middle, you'll see the dog tags. They have one in silver and one in black. Think they are $9.95. http://medicalert.org/home/HomeCatalog.aspx?Catalog=Standard I just like Medic Alert because they will keep all you info - Parents numbers, Emergency numbers, what meds you are on etc. I have never needed it, knock on wood, but I call every year to give them my updates etc. I'm sure if I'm alone, paramedics will know from the tag, my name and what I have and a phone number to get all medical and emergency info. Hope that is kinda what you are looking for. Good luck in the search!
