I would also like to know this! We never were even asked if we wanted to buy a micro chip for Sully.
Do they work? I know that Yorkies are often stolen out of yards and re-sold (that's why they're INdoor dogs and we protect Sully big time!)
We are still considering getting one for Sully, if he is not too old, but only if it is worth the money we will pay to do it! |
