How to Disable a Canine Microchip

By Jen Davis

Microchips are implanted under the skin of animals, primarily dogs, in order to identify the owner of a dog in the event that it is lost or stolen. Many veterinary clinics and virtually all animal shelters are equipped with microchip scanners that enable them to access the microchipped animal's owner information. Microchips are commonly placed in animals adopted from shelters and may also be placed in purebred puppies by the breeders. Microchips are intended to be permanent when they are placed in a dog. The only way to disable a microchip in a dog is to completely remove it from the animal.

Locate the microchip. You can do this by taking your dog to your vet and having it scanned. Note that different chips require different scanners; if your veterinarian does not have the proper brand of scanner, he may not be able to find the chip and you may have to try several animal shelters or clinics before you find a scanner that can.

Schedule an appointment with your veterinarian specifically to evaluate the microchip's location to give you an idea of how invasive or difficult the surgery will be to remove the microchip. You veterinarian may opt to perform some additional procedures, such as taking an x-ray of the microchip, to determine exactly what will be entailed in the surgical removal.

Schedule the surgery to remove the microchip. Follow any pre-surgical guidelines that are provided by your veterinarian.

Have your veterinarian remove the microchip from your animal. If you still wish to disable the microchip after it has been removed from your dog, smash it with a heavy item, such as a hammer. This will effectively disable the microchip.
