Getting a microchip put in your dog is a quick, in-office procedure done by a veterinarian. It takes only a few seconds, requires no anesthesia, and costs between $38 and $87 at most vet clinics. The chip itself is about the size of a grain of rice and sits just under the skin between your dog’s shoulder blades.
What Happens During the Procedure
Before anything touches your dog, the vet or technician scans the microchip while it’s still sealed in its sterile package. This confirms the identification number on the chip matches the number printed on the package barcode. It’s a simple quality check, but an important one.
Your dog will be positioned either standing or lying on their stomach. The vet pulls up the loose skin between the shoulder blades, then inserts the needle and injects the chip under the skin. The needle is slightly larger than what’s used for a standard vaccine, but the process feels similar to a routine shot. Most dogs barely react. After the chip is placed, the vet scans your dog’s body to verify the chip is reading correctly and sitting in the right spot.
The whole thing, from scanning the package to confirming placement, takes under a minute. No stitches, no sedation, no recovery period. You can schedule it during a regular wellness visit, and many vets offer it alongside vaccinations or spay/neuter appointments.
How Much It Costs
The national average runs about $48, though prices range from $38 to $87 depending on your location and the clinic. Some animal shelters and rescue organizations offer microchipping at reduced rates, sometimes as low as $20. Many shelters microchip dogs before adoption, so if you recently adopted, your dog may already have one.
Registering the Chip Is the Step Most People Miss
The microchip itself is just a tiny transponder with a unique ID number. It doesn’t do anything useful until that number is linked to your contact information in a registry database. This is the step that matters most, and it’s the one owners most often skip or forget about.
Some veterinary offices register the chip for you at the time of implantation. Others don’t. Ask your vet directly whether they’ve registered it, and if so, which registry they used. There are dozens of microchip registries, and knowing which one holds your information is essential.
If you need to register it yourself, you’ll create an online account with the microchip company and enter your dog’s details: name, breed, age, color, and any medical issues. You’ll also add your own name, phone number, email, home address, and the contact information for a backup person like a family member. Including your vet’s contact info is also a good idea. Keep this information current. If you move or change phone numbers, updating the registry takes only a few minutes and could be the difference between getting your dog back or not.
If you’re unsure whether your dog is already chipped, or you’ve lost track of the microchip number, any vet clinic can scan your dog for free. The American Animal Hospital Association also offers a free online lookup tool where you can type in a microchip number and find out which registry it’s connected to.
Why Microchipping Works
Collars and tags fall off. Microchips don’t. A national study from Ohio State University found that when microchipped pets arrived at shelters, owners were located in nearly 73% of cases. For dogs specifically, the return-to-owner rate was two and a half times higher for microchipped dogs compared to dogs without chips.
The chip operates on a 134.2 kHz radio frequency, which is the international standard. It has no battery and no GPS. It sits dormant under the skin until a scanner passes over it, at which point it transmits the ID number. Shelters, vet offices, and animal control agencies all carry compatible scanners. When a lost dog is found and scanned, the number pulls up the owner’s contact details from the registry.
Safety and Side Effects
Microchipping is one of the safest routine procedures in veterinary medicine. The British Small Animal Veterinary Association has tracked adverse reactions since 1996 and recorded only 391 incidents out of more than four million microchipped animals. That’s a complication rate well below 0.01%.
The most common issue is minor soreness at the injection site, similar to what you’d expect after any shot. A small bump may form temporarily. In rare cases, a chip can migrate from its original position between the shoulder blades to somewhere else under the skin. This doesn’t usually cause problems, but it’s why vets scan the entire body rather than just one spot when checking for a chip. Insertion into the spinal canal has been documented, but it is extremely rare.
Can You Do It Yourself?
Microchip kits are sold online, and technically the equipment is available to anyone. But this is not a DIY project worth attempting. The needle is large, the placement needs to be precise, and improper insertion carries real risks, from infection to chip migration to the rare but serious possibility of hitting the spinal canal. A veterinarian knows the correct depth, angle, and anatomical landmarks. Given that the entire procedure costs less than $50 at most clinics and takes seconds to perform, there’s no practical reason to do it at home.
What to Do After Your Dog Is Chipped
Check the injection site for a day or two. A tiny bump or mild tenderness is normal and typically resolves on its own. Avoid vigorous scratching or rough play around the area for the first 24 hours.
The more important follow-up is administrative. Confirm with your vet that the chip was registered and note which registry was used. Log into the registry account within the first week to verify all your details are correct. Set a reminder to update the registry any time your contact information changes. A microchip with outdated phone numbers is almost as useless as no microchip at all.
