The short answer
A microchip is a permanent ID implanted under the skin, but it only reunites you with a lost dog if the chip's registry has your current contact details. Ask your vet to scan the chip at every visit and update the registry whenever you move or change phone numbers.
How chips work
A chip the size of a grain of rice stores a unique number. Shelters and clinics scan it and look up the owner in the chip company's registry. It is not a GPS tracker.
Keep it working
- Register the chip in your name when you bring your puppy home
- Update the registry after every move or phone change
- Ask your vet to scan the chip at annual checkups
- Use an ISO 11784/11785 (15-digit) chip if you may travel internationally
- Record the chip number in your dog's PawTrace passport
Chips and city licences
A microchip does not replace a municipal dog licence where one is required. Many cities offer lower licence fees for microchipped dogs.
Frequently asked questions
Is microchipping mandatory in Canada?
There's no national requirement, but some municipalities and provinces require or encourage it, and most shelters and good breeders chip every dog before rehoming.
How do I find out which registry my dog's chip uses?
Ask any vet or shelter to scan the chip, then search the number on the manufacturer's website or a universal chip lookup.
