I don't know what it cost because we had it done while one was being spayed & the other was having teeth cleaned. Don't think it cost too much though. The gave us an envelope with the chip's number on it for registering. I logged into the chip manufacturer's webside, set up an account and entered the information on there, paid a small fee and that was it. I have the paperwork in a file for easy reference, but I think the payment is a one time thing. |
