I bought a dog from a shelter in IL a while back that came microchipped. I declined to fill out the form with my personal info.

If a collar and tag with my phone # & address have been sufficient for dogs for decades I see no reason to go all fancy and high-tech.

Depends on how much you love your dog. My dog was microchipped when she was a puppy - the number is sent to this outfit that has my name, phone number, email address, backup person .... that's all that's needed. You do the same thing when presenting a check ...

And she's worth it
