TL;DR — Pet Microchip Implant
Pet microchips are tiny permanent IDs — about the size of a grain of rice — that are implanted under your pet’s skin (between the shoulder blades). Each chip carries a unique identification number that links to your contact information in a microchip registry. If your pet is lost and scanned at a vet or shelter, the chip connects them back to you. Registration and keeping your info up to date are critical for recovery.
Key Points:
- What it is: A grain-sized RFID chip inserted under the skin; painless and quick, like a vaccination.
- How it works: Scanner activates the chip → transmits unique ID → registry matches it to owner info.
- Not a GPS: Chips don’t track location, they provide secure identification only.
- Placement: Standard injection between the shoulder blades for easy scanning.
- Why register: Without registration or updated contact info, the chip cannot reunite you with your pet.
- Peace of mind: A permanent backup ID that won’t fall off like collars or tags.
Collars and tags are still useful, but a registered microchip gives your pet a lifelong safety net.
What if your dog or cat went missing? Would someone know how to get them back to you? A microchip is a tiny form of identification that can help reunite a lost pet with its owner. When a pet is microchipped, it carries a unique identification number that connects to a registry with the owner’s contact information.
Microchip implantation is a quick procedure often done at a veterinarian, animal hospital, or through humane societies. Once the microchip is implanted, it must be registered with a microchip registry to ensure the microchip number can be traced. If the pet is found and brought to an animal shelter, a microchip scanner is used to detect the chip and display the ID number.
This number is then matched in the registry database to reach the pet’s owner and complete the pet recovery process. Without registration, even a universal scanner may not help if the microchip can’t be identified or linked to current contact details. Read on to learn how registering your pet’s microchip can offer peace of mind and help get your pet back.
What Is a Pet Microchip

A pet microchip is a tiny radio frequency identification (RFID) device, about the size of a grain of rice, used for permanent pet identification. The microchip can be implanted under the skin, typically between the shoulder blades, using a quick injection process. Each microchip contains a unique ID number that, when scanned by a shelter's scanner or a universal microchip reader, transmits the identification number to the scanner to help identify the pet and contact the pet owner.
How Does a Pet Microchip Work

A pet microchip works through a simple but effective radio frequency identification (RFID) system designed for permanent pet identification. It helps link a lost or stolen pet to its rightful owner by transmitting a unique ID number when scanned. This process is essential for shelters, veterinarians, and animal control officers to reunite pets with their families.
How the Microchipping System Works
- Implanting a Microchip: A veterinarian injects the microchip under the pet’s skin, usually at the back of the neck, using a syringe, similar to a vaccination.
- Microchips Used: These chips are tiny, passive RFID devices that do not require batteries and remain dormant until activated by a scanner.
- Scanner Activate the Chip: When a shelter's scanner or a universal microchip reader passes over the chip, it powers the device momentarily.
- Transmit Unique ID: The chip then transmits a unique ID number to the scanner.
- Displays the Number: The scanner displays this number, which is linked to the pet owner’s contact information in a microchip registry.
- Identification and Recovery: Shelters and humane societies across the country use this system to contact pet parents and help pets make it home.
Important Considerations
- The microchip may not work if it isn’t registered or if the pet owner forgets to update their contact details.
- Different microchip brands exist, but many scanners today are designed to read a universal microchip.
- A microchip is not a GPS device; it provides identification, not location tracking.
- Implanted microchips can’t fall off like a tag the pet is wearing, offering reliable backup if the pet is lost.
How Does a Pet Microchip Identification Help Identify Your Pet

Microchip identification helps ensure that a lost pet can be quickly and accurately matched with its owner. Unlike collars or information on the tag, a microchip is a permanent form of identification that stays with your pet for life. Microchips are tiny and offer a secure, reliable way to prove ownership, even if your pet has no visible ID.
How Microchip Identification Connects You to Your Pet
- Unique Microchip: Each microchip contains a unique identification number that is different for every pet.
- Chips Are Usually Inserted: The microchip is injected under the skin using a quick procedure, often performed by a veterinarian or animal hospital.
- Microchip Is Scanned: When a lost dog or new pet is found, a scanner often used at shelters activates the chip.
- Powered by the Scanner: The chip transmits the pet’s microchip number to the scanner display.
- Finder Uses the Registry: The finder uses the microchip registry to locate the pet’s owner, provided the microchip is registered.
Why Keeping Your Contact Information Updated Matters
- If you move or change phone numbers and forget to register the new details, the microchip cannot help identify the pet.
- Responsible pet owners must keep their contact information current to ensure a smooth reunion.
- The veterinary medical association and microchip manufacturers emphasize the importance of maintaining accurate registry data.
- Microchips work well even if pet doors or tags are lost or removed, as long as the microchip is registered.
Where is a Pet Microchip Injected Under the Skin

A pet microchip is injected under the skin at the back of the neck, specifically between the shoulder blades. This spot is standard because it's easy for veterinarians, shelters, and animal control officers to locate and scan. The microchip is about the size of a grain of rice and is inserted using a syringe, much like a vaccination.
Key points about microchip placement:
- Location: Injected between the shoulder blades (back of the neck).
- Procedure: Quick and minimally invasive, similar to a vaccination.
- Security: The chip stays in place under the skin and doesn’t move around easily.
- Detection: Easily scanned by a shelter’s scanner or universal reader.
- Effectiveness: Placement ensures consistent, reliable identification if a pet is found.
Why Registering Your Pet’s Microchip Brings Peace of Mind

Registering your pet’s microchip ensures that their unique identification number is linked to your up-to-date contact information in a national or global microchip registry. Without registration, a microchip, even if scanned, won’t lead to you as the pet’s owner, making recovery difficult. A registered microchip provides a dependable way for shelters, veterinarians, or animal control to contact you if your pet is lost or stolen.
Benefits of Registering Your Pet’s Microchip
- Direct Link to You: A registered microchip connects your pet’s microchip number to your name, phone number, and address.
- Recovery Assurance: If your pet is lost, scanned, and their chip is registered, the finder can contact you quickly.
- Covers Life Changes: Updating the registry if you move or change phone numbers ensures your contact info remains accurate.
- Protection Against Mix-Ups: Even if your pet is confused with a similar one or has no tag, the microchip provides a unique, permanent ID.
- Trusted System: Supported by the veterinary medical association and microchip manufacturers, the system is recognized and widely used.
Final Thoughts
Pet microchipping is a simple yet powerful way to protect your pet and ensure they can be identified if lost or stolen. The microchip, about the size of a grain of rice, carries a unique identification number that stays with your pet for life.
When scanned by a shelter or veterinarian, this number can connect your pet to you if it’s properly registered. Keeping your contact information up to date in a trusted microchip registry is crucial for the system to work.
Microchipping doesn’t replace collars or tags, but it adds a permanent, secure layer of identification. For every responsible pet owner, microchipping offers peace of mind and a reliable path home for your furry companion.
Frequently Asked Questions
What is a pet microchip, and how is it implanted under the skin at the back of the neck?
