Just getting your pet microchipped is not enough.
You must make sure it is REGISTERED and that you continue to update your contact info!
Rescues adopted from a rescue organization or a shelter often are microchipped when they are adopted. And SOME of those adoptive organizations register the pet with them as a back-up. Not all do so. As the owner you need to be sure that you register YOUR info as well. So when you move or change a phone number be sure you update your info.
Check out this recent story for an example of what can happen when info isn’t updated.
This story ended happily, but not all do.
