Does microchipping hurt dogs?

Microchip implantation is a quick, minimally invasive procedure, similar to a routine vaccination. Most dogs react no more than they would to a standard shot. No anesthesia is required and the procedure takes less than a minute.

How much does it cost to microchip a dog?

Microchipping typically costs between $25-60 at most veterinary clinics. Some shelters and rescue organizations offer microchipping at reduced cost or for free during adoption events. It is a one-time cost for lifetime identification.

Do I need to register my dog's microchip?

Yes - this is the most critical step that many owners miss. The chip itself contains only a number. Your contact information must be registered in a microchip database separately. Without registration, a found chip cannot be traced back to you.

What if my contact information changes after microchipping?

Update your microchip registry immediately whenever your phone number, address, or ownership changes. An unregistered or outdated microchip is nearly useless. Use the AAHA Universal Pet Microchip Lookup tool to confirm your chip is findable and your information is current.

How to Microchip Your Dog: Everything You Need to Know

Q: Can a microchip replace an ID tag?

No - a microchip requires a scanner to read and provides no visible indication that your dog is identified. An ID tag is immediately visible and accessible to anyone who finds your dog without any special equipment. The best approach is to use both: a microchip as a permanent backup and a QR tag for immediate identification.

Veterinarian scanning a dog for a microchip – Dog Safety & ID | Doggo Dream Shop

A microchip is one of the most permanent and reliable forms of identification you can give your dog. Unlike a collar or tag that can fall off or be removed, a microchip stays with your dog for life. But microchipping is only effective if done correctly — and many pet owners don't realize that registration is a separate, critical step that's often skipped.

This guide covers everything you need to know about microchipping your dog. For a complete dog ID strategy, visit our Dog Safety & ID Guides hub.

What Is a Dog Microchip?

A microchip is a tiny radio-frequency identification (RFID) device — roughly the size of a grain of rice — implanted under your dog's skin, typically between the shoulder blades. It contains a unique identification number that can be read by a universal scanner.

When a lost dog is brought to a shelter, veterinary clinic, or animal control facility, staff scan for a microchip. If one is found, they look up the ID number in a microchip registry to find the owner's contact information. According to the ASPCA, microchipped dogs are more than twice as likely to be returned to their owners as non-microchipped dogs.

How Is a Microchip Implanted?

Microchip implantation is a quick, minimally invasive procedure performed by a veterinarian or trained technician. A needle injects the chip under the skin — no anesthesia required. Most dogs react no more than they would to a routine vaccination. The procedure typically takes less than a minute and costs between $25–60 at most veterinary clinics.

The Critical Step Most Owners Miss: Registration

This is where many microchips fail. The chip itself contains only a number — it has no GPS capability and stores no personal information. Your contact details must be registered in a microchip database separately, and kept current.

Steps to complete registration:

Get your chip number — your vet will provide this after implantation; it's typically 15 digits
Choose a registry — major US registries include PetLink, HomeAgain, Found Animals, and the ASPCA's registry
Register your information — include your name, address, phone number, and a secondary contact
Update when anything changes — a new phone number, address, or owner means updating the registry immediately
Check your registration — use the AAHA Universal Pet Microchip Lookup tool to confirm your chip is findable across registries

Microchip vs. QR Pet ID Tag: Which Is Better?

Both — and they serve different purposes. A microchip is a permanent backup that works even if your dog loses their collar. A QR pet ID tag is immediately visible and accessible to anyone who finds your dog, without needing a scanner.

Microchip: permanent, scanner required, no visible indicator, works even without collar
QR tag: immediately visible, scannable by any smartphone, links to full digital profile with medical info and multiple contacts, no scanner required

The strongest ID strategy combines both: a QR pet ID tag for immediate identification by anyone who finds your dog, and a microchip as a permanent backup that can't be lost or removed. Make sure your dog also wears a well-fitted collar — see our Best Dog Collars for Training guide for collar selection guidance. For rescue dogs specifically, see our guide on QR Pet ID Tags for Rescue Dogs.

According to the AKC

The American Kennel Club recommends microchipping all dogs regardless of lifestyle — even dogs that are always indoors or on leash. Accidents happen, doors get left open, and disasters can separate dogs from their owners in ways no one anticipates. A microchip is a one-time procedure that provides lifetime protection.
