Understanding how to check a dog's microchip for migration and functionality is a critical step for any owner who wants to ensure their pet can be identified if they ever go missing. While you cannot see the chip itself, verifying that it is present, in the correct location, and readable by a standard scanner provides long-term peace of mind. This process does not replace professional veterinary care, and if you ever suspect a scanner is not detecting a chip that you know is present, you must contact your local vets to perform a more thorough examination.
Where should a dog's microchip be located?
A properly placed microchip should be located just under the skin in the area between the shoulder blades at the base of the dog's neck. When you or a professional scan for the chip, the scanner should be moved slowly in a circular motion around this area to detect the transponder's signal. If a chip has migrated, it may be found further down the back, near the shoulder, or even occasionally in the neck area. While migration is not typically dangerous for the dog, it can make the chip harder for a shelter or clinic to locate during an emergency, which is why periodic checks are recommended.
How do I check if a microchip is still functioning?
To check if a microchip is still functioning, you need access to a universal microchip scanner, which most veterinary clinics and animal control facilities use. You should bring your dog in for a routine check-up and specifically ask the staff to scan the animal to confirm the chip is active and transmitting a clear identification number. If the scanner fails to pick up a signal, it could mean the chip has failed, it has migrated to a difficult-to-reach area, or there is interference from a collar or metal tag. A professional can help you troubleshoot these issues and determine if a new chip is necessary.
What should I look for when verifying microchip registration?
Checking the functionality of the hardware is only half the battle; you must also ensure the information linked to that chip is accurate and current. Once the scanner reads the unique ID number, you must enter this code into the relevant pet recovery database to see what contact information appears. Verify that your current phone number, email address, and home address are all up to date. If you recently moved or changed your service provider, your old details might be listed, rendering the chip ineffective in a recovery scenario. This is a simple administrative task that you can perform through the manufacturer's website using your registration documents.
When should I have my dog's microchip checked?
You should have your dog's microchip checked at least once a year, preferably during an annual wellness exam. It is also wise to have it scanned whenever you visit a clinic for other reasons, such as vaccinations or routine care, to ensure nothing has changed. If you have recently adopted a dog or purchased a pet from one of the listings, verify the chip status as soon as possible to ensure the records are transferred into your name. Never assume a chip is working just because it was implanted years ago; hardware can occasionally fail, and confirming its status is a small effort for a significant safety benefit.
What if the microchip is not detected?
If a scanner fails to detect a chip, do not panic, as there are several reasons why this might happen. The scanner may simply be incompatible with the specific frequency of the chip, or the chip may have migrated to an area the scanner did not cover. If a professional scan confirms that the chip is truly non-functional or missing, you will need to discuss the option of having a new one implanted. This is a very standard, safe procedure that provides a new, working identification link for your pet. Always keep your physical paperwork in a safe place so you have the original microchip ID number as a reference for your records.
