Yup we do have the maker of the chip and the 15-digit identifier. The issue with changing the chip number, we will then need to re-do all vaccinations, blood tests, etc. Which will take 30-35 days, and she will have to stay in quarantine the entire time.
She was chipped by a company called partnerlab.ru which is an FDX-B ISO11784/85 134.2kHz chip, based in Russia. However, I can replace with a 125kHz chip once it is is ISO 11784/5 compliant.
