If the microchip isn’t present in the usual area (Diagram A), or the most common areas of migration then the rest of the animal should be thoroughly scanned.
For a full body scan we first recommend scanning in a slow S shaped pattern down the back of the animal in a transverse direction (Diagram B), before repeating the action in the same pattern in a longitudinal direction on both sides of the animal (Diagrams C and D). If a microchip is still not found, then proceed to slowly scan the chest and abdomen also. Microchips have been documented to migrate to many different areas if implanted in an improper location; and anyone who is going to be using a microchip scanner must learn to scan properly and thoroughly.
Vets, rescues, dog wardens and any organisation which is likely to encounter stray animals or those leaving the country should use a universal microchip scanner to ensure they can identify any microchip the animal may have inserted. Older or foreign animals may not have a standard FDX-B microchip implanted.
Our Universal Scanner will read ALL microchip types suitable for use in animals - click here for more information. Please be aware that universal scanners have to scan across different frequencies, and so need enough time to ensure the scanner can cycle through the different frequencies needed to pick up some foreign and encrypted microchips.
This scanning technique can be modified to suit the species of animal being scanned, as long as scanning is carried out slowly, using a methodical pattern and with the scanner kept in contact with the animals coat.
