Our dog has an ISO standard microchip implanted in Hungary according to this page:
This transponder has a country code according to ISO 3166 from Hungary, the manufacturer is "Felixcan S.L." and the product is granted as injectable. The transponder is ISO conform.
In 2013 she had a rabies vaccination in Hungary, and this is visible in the hungarian database. After we moved with her to the UK. This year we are travelling again so she got a vaccination in the UK on the 1st of February. We got the stamp in her passport, and have been told that the microchip has been updated. Now I am trying to check the public online databases and I don't see the recent update. From here I found out that every country has its own database(s). UK has the Petlog, that one knows nothing about our microchip. This very nice page queries almost all local databases, and it finds nothing, although tells the UK database has some communication issues.
At the UK clinic we had the rabies vaccination I could only talk to the receptionist so far, and she could not help. I am worried and want to be sure that we can cross the border with no problem. What is the best way to find this out? Also this brings up a more generic question: how this whole system works? If the Vet inputs data, where it will be recorded, how these databases exchange data between each other, how the international database Europetnet collects the data, and how often? And how the border authorities check the database?
