My wife and I have decided to get Vinnie microchipped, unfortunately we decided to do this after someone took our femail corgi...

A very hard lessen learned.  I've been reading online and there is a lot of information all of which doesn't really tell you much.  Do I call my vet and just use whatever Chip he deals with?  or do I investigate which one is better than the other?  It seems like there are several chip companies and the possiblity of your chip not being read by some chip readers....

I'd love to put a GPS tracking chip in him, but it seems that technology is not yet available, which I cannot believe there isn't anything out there like that for the general public.

I'm new to this forum and wasn't sure exactly where to ask the question so hopefully I didn't put this in the wrong place.
