Good article about microchips and all the confusion and how they really work. I use AKC for now, but may change to another chip if I find one that is an ISO and compatable with AKC scanners. So far my AKC scanner reads all chips from all manufactures. You can register your number on all the free sites and then pay for AKC if you wish. It's up to the owner to get the number to as many companies as possible. As far as I know all registry companies take all chips, no matter the maker.
A must read site for everything dogs, politics and about your so-called registry companies.
