Every Friesian horse entered into the FPS Foal Book since 1997 has received an electronic identification code, or microchip. This chip is injected into the upper left neck, approximately mid way between the withers and the poll, usually when the horse is a foal, and has just been inspected and accepted into the Foal Book. (This has recently changed in the US, so that Foals are microchipped by a private vet before the Inspection.) This electronic ID code is recorded on the horse’s registration certificate. The implanted chip can be read by certain microchip readers,available through most veterinarians and the FHANA office, though a different reader is needed for European and North American microchips. These chips ensure the correct identity of each horse, especially useful in a breed which display very similar coloration and other physical characteristics.
