If you post of a forum you tend to get people's opinions whether you asked or wanted them or not I'm afraid!
I am guessing the reason a vet won't remove it is because they believe the risk in removing it is greater than the risk of leaving it where it is, and therefore it goes against their code of conduct to remove it. Removing would mean risk of infection, cause pain to the animal etc. The only way you may find a vet to do it would be to ring round, but it is doubtful they would remove it, I am afraid.
If you feel there is a problem with the microchip being in, then why have it because it suited your purpose at the time? (eg. travelling abroad so felt it was needed?) But now you feel it is such a problem/danger that you would like it removed?
I appreciate the recent scare mongering re microchips has some owners worried, and I am the last person to do anything that isn't neede dmedically to my dogs (no routine vaccs, no feedign commercial processed foods etc) but mine are all microchipped, despite the fact I am as sure as I ever could be that they will never be needed. To me, the risk from a microchip is smaller than the risk of my beloved pet getting lost and never returned to me.
