Microchips placed in dogs are small passive radio emitters about the size of a grain of rice that are injected under the skin above the shoulder blades. Each microchip has a unique number, and that number is registered on an official central database along with a description of that dog, the owner's name, address, and contact phone numbers. [1]

When a scanner is passed over the microchip, that unique number is picked up and displayed on the scanner. Knowing if a dog has a microchip is especially helpful if you find a stray dog and need to trace the owner. [3]

Checking if a Dog Is Microchipped
The best way to tell if a dog is microchipped is to take them to a vet or animal shelter to get scanned. You can also check the dog’s collar to see if it says they’re microchipped. Or, feel for a firm, rice-sized object between the dog’s neck and shoulder blades.
Steps
-
Look for a tag on the dog's collar. If the dog is wearing a collar take a look to see if it has a specific tag that says the dog is microchipped. Microchips are made by different manufacturers, and these companies usually issue a metal tags to place on the dog's collar to alert interested parties that the dog is chipped. [4] X Research source
- The tag is supplied in part to let anyone that finds a dog know that it is chipped in order to scan them but it is also a visual deterrent to potential thieves thinking of stealing the dog, since the dog has permanent ID as belonging to someone else.

- If the dog does not have an official ID tag on their collar, look for a bespoke collar tag bearing wording such as "I am microchipped" or "microchipped." Know that this is not the same as a tag engraved with the dog's name and phone number. The purpose of this tag is purely to alert the finder that the dog is chipped and should be scanned. This type of tag usually does not carry personal details.
-
Feel for the microchip. If the dog has lost their collar or there is no tag on the collar, try gently feeling for the presence of the microchip. The microchip is encased in a perspex coat that is the size and shape of a grain of rice. Microchips are injected under the skin in the loose skin of the neck at the centerline between the shoulder blades. Therefore this is the ideal place to start feeling.

- Run your fingertips over the skin between the shoulder blades and neck. Apply gentle pressure to see if you can detect a firm rice-grain sized object just under the skin. Microchips do bed in, which means they can migrate slightly from the original implant site.
- To reduce the chance of missing a microchip, work in a methodical manner working up and down between shoulder and head and then left to right working side to side from the shoulders up the neck until every inch is covered.
- This is not a foolproof method. If you can't feel a chip it does not mean the dog is definitely not chipped because the chip may be present but have shifted location or is embedded too deeply to feel.

Get a definitive answer by getting the dog scanned. Even if the dog doesn't have a tag that says it has a chip and you don't feel one, it's best to scan the dog to find out. It is worth scanning for a microchip if you are trying to get the contact details of a lost dog's owner. [7] X Expert Source Ray Spragley, DVM
Veterinarian Expert Interview. 29 June 2021.Diane Morgan, Pet Care and Animal Welfare AuthorTo determine if a dog is microchipped, a simple scan by a veterinarian or animal shelter can reveal the presence of a chip. About the size of a grain of rice, microchips are typically implanted between the shoulder blades. While physical detection is possible, it is unreliable since chips may migrate. Therefore, scanning is the most effective identification method for microchipped dogs, providing lost pets the best chance at reunification with owners.
-
X-ray the dog. Microchips show up on x-ray. While this is not routinely used as a method to check if a chip is present, in cases where a chip was implanted and has stopped working, taking a radiograph of the dog is a quick and easy way to check the chip is still in place but not working.

Check the scanner. First, the operator needs to check that the scanner is working by pressing the 'on' button and passing the sensor over a test chip. If the scanner bleeps and displays a number it is working. If the batteries are dead the display will either remain blank or display a message "low battery."
- If the scanner is working but has not scanned a microchip after a set period of time it displays the message "no chip found."
-
Scan the dog's shoulders. Turn on the scanner and hold it one inch above the skin. Move the scanner in up and down sweeps from the shoulder to neck and then from side to side. When the scanner activates, make a note of the number.
-
Check other places on the dog's body. If no chip is found with a methodical scanning pattern over the shoulders, don't give up. Pass the scanner over the remainder of the body. This includes under the sternum and around the armpits, just in case it has migrated to an unusual location.

Tips
- Microchip scanning can be done at most veterinary clinics. If you have found a stray dog, take it to a local veterinarian to get scanned.Thanks
- Microchips are also a great way of proving ownership. Your veterinarian or an animal welfare officer can implant the chip and put your information into the database. This process means the pet is officially registered with your details. The database then issues the owner a certificate, which has a copy of the details and a password. Thus, the only person capable of changing the registered details is the owner in possession of a valid password. This means that if your dog is stolen and then spotted by the police, the results of scanning the microchip can prove that you own that animal.Thanks

Article Summary

To tell if a dog is microchipped, gently feel the dog’s skin between its shoulder blades and its neck. See if you can feel a small, hard object about the size of a grain of rice just beneath the skin. If so, the dog is microchipped. If you can’t feel a chip, however, the dog may still have one. The chip may have shifted location or have become embedded too deeply to feel. In this case, you will need to use a microchip scanner to locate the chip. For tips from our veterinary reviewer on using a microchip scanner, read on!
