Breeders in England, Scotland and Wales must ensure puppies are microchipped and registered with an approved microchip database by the time the puppies are 8 weeks old (prior to going to the new owner).

What does this mean for you?

  • Dogs must be recorded on a database in the name of the keeper – this is defined as the person with whom the dog normally resides.
  • DEFRA recognise that some welfare organisations record themselves as the ‘owner/keeper’. However, if the dog has been rehomed, they expect the record to be updated to the person with whom the dog normally resides.

Scanning Guidance

Before scanning an animal, check that the scanner is working and that you know the correct orientation of the make of scanner being used to maximise the likelihood of detection in the microchip.

The microchip scanner should be passed slowly over the surface of the animal, moving the scanner in an “S” shaped pattern over the dorsum of the animal.

Scanning should begin and concentrate over the standard implantation site in the UK, which is midway between the shoulder blades (this should take 10-20 seconds). If no chip is detected, rotate the scanner 90 degrees and rescan the animal.

If the microchip is not detected here, you should scan down the left side of the neck (the standard implantation side in Europe) then down the back, on the sides, over the shoulders and down to the elbows.

If a microchip is still not detected where there is evidence that a microchip has been implanted the following should be considered:

  • Scan other areas of the body to see if the microchip has migrated. Start at the pet’s head, and slowly scan side-to-side all the way to the pet’s tail. Then, slowly scan down the pet’s leg, across its neck, along and under its chest and behind its front legs.
  • Change the orientation of the scanner and rescan the animal.
  • Rescan the animal with a different scanner.
