Microchipping Dogs: Cost, Process & Why It Matters
Start here
A microchip is a rice-grain-sized ID implanted under your dog's skin that carries a unique number a shelter or vet can scan. It's the most reliable way to get a lost dog home, because — unlike a collar tag — it can't fall off. The chip only works if you register it and keep your contact details current, so the number links back to you.
What a microchip actually is
A microchip is a tiny passive transponder, about the size of a grain of rice, that a vet places under the loose skin between your dog's shoulder blades. It has no battery and no GPS — it does nothing until a scanner passes over it, at which point it transmits a unique identification number. That number is the key: entered into a pet-recovery database, it links to your name and phone number.
It's important to understand what a chip is not. It will not track your dog's location or tell you where a lost dog wandered. It's an ID, not a locator. Its whole value is that it's permanent and can't be lost the way a collar or tag can.
The implant process
Microchipping is a routine, in-and-out procedure. The vet loads a pre-sterilized chip into a hypodermic applicator and injects it under the skin — it feels much like a regular vaccination, a quick pinch, and most dogs barely react. No anesthesia is needed, though many owners choose to have it done during a spay/neuter surgery when the dog is already under.
- Who does it: a veterinarian, and many shelters and some pet clinics.
- Age: puppies can be chipped from a few weeks old; there's no upper age limit.
- Aftercare: none, really — no stitches, no recovery time.
Registration is the step that matters
A chip that isn't registered — or is registered to an old phone number — can't bring your dog home. The most common reason microchips fail to reunite pets is outdated owner information, not the chip itself.
After the chip is implanted, you must enroll its number in a pet-recovery database and enter your current contact details. When you move or change your phone number, update the registry. If you adopt a dog that's already chipped, transfer the registration into your name — don't assume the shelter did it. You can confirm a chip's details by looking up the number through the AAHA Universal Pet Microchip Lookup tool online.
What it costs
Microchipping is one of the cheapest forms of insurance you'll ever buy for a dog. Costs vary by region and provider:
| Item | Typical cost |
|---|---|
| Chip implant at a vet | Roughly $25–$60, often a one-time fee |
| Low-cost clinic or shelter | Sometimes free or heavily discounted |
| Database registration | Free to a small one-time or annual fee, depending on registry |
There are no ongoing costs for the chip itself; it's designed to last your dog's lifetime.
Chips, tags, and everyday ID
A microchip is a backstop, not a replacement for a collar and tag. A visible tag with your phone number lets any neighbor return your dog immediately, without a trip to a scanner. Think of it as two layers: the tag for the quick, friendly reunion, and the chip for when the collar is gone.
Practical take: Chip your dog, register the chip, keep a collar tag on, and set a reminder to verify your registry details once a year. Those four steps cover the vast majority of lost-dog scenarios.
Keeping the details where you can find them
The information that gets a lost dog home — the chip number, the registry it's enrolled in, your current contact details — is easy to forget until the moment you desperately need it. Keeping it recorded alongside your dog's vaccination dates and medical history means it's one tap away in an emergency, and it's simple to check that everything is still current. Logging it once, and revisiting it after a move or a new phone, turns a good intention into a reliable safety net.
Keep your dog's chip number where you'll actually find it
Tavi stores your dog's microchip number, registry, vaccination records and medical history in one place — so if your dog ever goes missing, the details a shelter needs are one tap away instead of buried in a drawer. Free for your first pet.
Frequently asked questions
Does microchipping hurt a dog?
It feels like a routine vaccination — a quick pinch as the chip is injected under the skin between the shoulder blades. No anesthesia is needed and most dogs barely react. There's no recovery time or aftercare.
Can a microchip track my lost dog's location?
No. A microchip is an ID, not a GPS device. It has no battery and does nothing until a scanner reads its number. To reunite you with a lost dog, someone has to find the dog and scan the chip, then look up your registered contact details.
How long does a dog microchip last?
A microchip is designed to last your dog's entire life. It's a passive device with no battery to run down or replace. The only maintenance is keeping your contact information current in the registry.
What happens if I move or change my phone number?
You must update your details with the microchip registry. An out-of-date phone number is the most common reason a chip fails to reunite a lost dog with its owner. Verifying your registration once a year is a good habit.
Is a microchip enough, or does my dog still need a collar tag?
Your dog should have both. A visible collar tag lets a neighbor return your dog immediately without needing a scanner, while the microchip is the permanent backup for when the collar comes off. Use them together as two layers of ID.
