The Complete Guide to Microchipping Your Pet
A microchip is the single most effective way to ensure your lost pet makes it home. Here's everything you need to know.
How Microchips Work
A microchip is a tiny radio-frequency identification (RFID) transponder about the size of a grain of rice. It's injected under the skin between the shoulder blades.
The chip contains a unique ID number — no GPS, no battery, no moving parts. When a scanner is passed over the chip, it transmits the ID number, which is linked to your contact information in a database.
It's not GPS tracking. A microchip doesn't track location. It identifies your pet when scanned by a vet or shelter.
The Procedure
- Duration: 10-15 seconds
- Pain level: Similar to a vaccination — a quick pinch
- Anaesthesia: Not required (often done during desexing surgery for convenience)
- Age: Can be done at any age; commonly at 8 weeks or at desexing
- Recovery: None needed. Your pet can resume normal activity immediately.
Why Every Pet Needs One
The Statistics
- Dogs without microchips are returned to owners 22% of the time
- Dogs WITH microchips are returned 52% of the time
- Cats without microchips: 2% return rate
- Cats WITH microchips: 38% return rate
Collars Fail
Collars and tags can fall off, be removed, or become unreadable. A microchip is permanent, internal, and tamper-proof.
Legal Requirements
Many jurisdictions now legally require microchipping. Check your local regulations.
Travel
International pet travel almost universally requires microchipping. Some countries require the chip before rabies vaccination.
Cost
- At a vet clinic: $40-$75 (includes chip, insertion, and database registration)
- At a shelter/rescue: Often included in adoption fee
- Community microchip events: $15-$30
After Microchipping: The Critical Step Most People Miss
Register the chip. A microchip is useless if your contact information isn't in the database.
- Ask your vet which database the chip is registered with
- Create an account on that database
- Enter your current phone number, address, and email
- Add a secondary contact (partner, family member)
- Update your details whenever you move or change phone numbers
This is the #1 reason microchipped pets aren't returned — outdated or missing registration information.
Common Myths
"It can cause cancer" — Extremely rare. The British Small Animal Veterinary Association found 2 cases out of 4 million chips.
"My pet never goes outside" — Doors get left open. Cats escape through windows. Natural disasters happen. Indoor-only pets need chips too.
"It hurts" — No more than a standard vaccination. Puppies and kittens tolerate it easily.
"It tracks my pet's location" — No. It's an ID chip, not GPS. For tracking, you need a GPS collar.
Checking Your Pet's Chip
Ask your vet to scan for the chip at every annual visit to confirm:
- The chip is still readable
- The chip hasn't migrated significantly
- Your registration is up to date
