Yes, microchips can occasionally migrate from the original implantation site within the pet's body, typically moving only a short distance. This migration can occur if the microchip is not implanted correctly or if the pet's activity causes it to shift. Migration is generally rare when the chip is placed correctly between the shoulder blades. While migration might complicate locating the chip with a scanner, it does not affect the microchip's functionality; the chip will still operate and transmit the identification number when scanned.
