Having your pet micro chipped, along with keeping the collar and tag information current, gives your pet the best chance of being identified and returned to you if he or she gets lost. Microchips are about the size of a large grain of rice. The technology used is based on a passive RFID (Radio Frequency Identification) technology. Lost pets that are brought into shelters or animal hospitals are always scanned for a microchip. Microchip implantation can be performed in our office quickly and without sedation.
