Your dog has a microchip, a tag on the collar and a folder of paperwork. Does that mean everything is in place if they go missing?

Possibly—but only if the records behind that identification lead to someone who can be reached. A chip number in a drawer, an expired municipal licence or a tag carrying an old phone number can leave a gap you may not discover until you need it.

This guide explains how dog licences, microchips and visible identification work together, what to check when bringing a dog home, and which details to update when life changes.

Municipal examples and fees were checked on September 27, 2026. Requirements depend on where you live; use your local authority’s current instructions for your address.

Dog identification: what each part actually does

The BC SPCA’s identification guidance explains the value of combining visible identification with permanent ID linked to current records. One method can help when another is unavailable.

Do all dogs in Canada need a licence?

Start with the authority responsible for animal services where your dog lives. Do not assume a rule you remember from another town applies at your new address.

The municipal examples below show why checking matters. Fees, age thresholds, renewals and transfer processes can differ. These examples are not a complete list of Canadian requirements.

For your own location, confirm when registration is due, what supporting documents are needed, whether the tag must be worn, and how renewals work. Ask about any applicable assistance or concession rather than assuming you qualify.

If your address is outside a city boundary, contact the township, regional authority or community office responsible for animal services. The nearest city’s licence page may not cover your home.

A microchip is an identifier, not GPS

The BC Pet Registry explains that a microchip uses radio-frequency identification and is read when scanned. It cannot show your dog’s location on a map.

That distinction changes what you should expect if your dog disappears. A chip can help identify a dog after someone finds and scans them. It does not send you an alert simply because your dog has left the yard.

Think through the handoff: a clinic or shelter reads the number, the relevant registration is located, and someone uses the contact information on file. Your practical responsibility is to make sure that information is useful.

“Microchipped” and “registered to me” are separate checks

A dog may arrive already chipped by a breeder, clinic or adoption organization. Ask who completed the registration and whether any transfer step remains for you.

Get the number and registry details in writing. Sign in or contact the registry to confirm your information. If you cannot find the paperwork, ask your veterinarian to scan the dog and help you identify the next step.

Do not book another implant simply because you do not know the existing number. First establish what identification your dog already has.

What if I know the number but not the registry?

The AAHA microchip registry lookup tool can help identify participating registries associated with a chip number. It is a lookup service, not a place to register your dog or edit your contact information. Follow up with the registry itself.

If a lookup does not resolve the question, ask the implanting clinic, breeder or adoption organization for assistance. Keep the question open until you have confirmed a usable record, rather than assuming a saved number is enough.

Your new-dog paperwork handover

Whether you are bringing home a puppy or an adult dog, make identification part of the handover conversation.

1. Obtain the microchip number and registry details, if the dog is chipped.

2. Ask whether registration is complete, pending or still associated with a previous contact.

3. Complete the registry’s transfer process where required, and save confirmation.

4. Check your local dog-licensing requirements and complete the appropriate application.

5. Arrange visible identification carrying a current contact number.

6. Keep a clear recent photograph and copies of the relevant records together.

Pedigree paperwork, a veterinary account, a municipal licence and a microchip registry should each be checked for its own purpose. Do not assume that completing one organization’s form updates all the others.

Where a breeder or adoption organization remains an additional contact under an agreed arrangement, clarify how the record works and who will be called. The important practical question is whether someone can reach you promptly.

Make a visible tag useful

Choose lettering you can read easily and inspect the attachment regularly. Check the phone number character by character before ordering.

A mobile number you answer while away from home is useful. Consider a secondary contact, with that person’s agreement. If you choose a QR tag, test the public page yourself and review what personal information it displays.

You can make your own privacy choices without making the tag difficult to use. The purpose is to give a finder a workable route to you. Keep private documents and complete registry records off public social posts.

Check the tag again when you replace a collar or harness. It is easy to move the walking equipment and leave the identification behind.

Visible ID does not replace secure equipment or supervision. It is one part of your preparation if those precautions fail.

Moving house: update every relevant record

Put dog identification on the same moving checklist as utilities and mail. Make a separate entry for each organization so you can mark it complete.

• Microchip registry: address, phone numbers, email and backup contacts.

• Municipal licensing account: new address and any required change of jurisdiction.

• Visible tag: any contact number that has changed.

• Veterinary clinic, insurer and regular caregivers: the information each needs.

Ask the new licensing authority whether it offers a transfer arrangement or requires a new application. Vancouver, for example, lists an $8 transfer process for a valid licence from another municipality, retaining its existing expiry date. That is a specific local process, not a nationwide rule.

Keep confirmation emails until you have checked the updated records. Changing the address at your clinic does not establish that your municipal or registry account has also changed.

Changing phone numbers deserves the same attention

You may keep the same home for years and still become unreachable through an old number. Before giving up a phone number or email account, review your dog’s identification records.

Also revisit backup contacts. A person who has moved overseas or no longer knows your dog may no longer be the best choice.

Travelling or leaving your dog with a caregiver

Before a trip, confirm that the contact number on your dog’s tag will work where you are going. Check your account access before you are away from familiar devices.

Give a sitter or boarding provider a concise emergency information sheet with your contact details, a backup person, your veterinary clinic and relevant identification information. Explain who to contact if you cannot be reached.

For a temporary stay, ask the destination authority about any local requirements that apply. Identification is also separate from travel-entry documentation; a licence or microchip alone should not be treated as proof that all travel requirements are satisfied.

If you use a tracker, test it before departure and make its charging routine part of the packing plan. Follow the manufacturer’s instructions for the specific device.

For help with the next step, prepare for a sitter or boarding stay.

If your dog goes missing

Begin local reporting promptly. Contact the animal services agency and shelters serving the area where the dog disappeared, and notify nearby veterinary clinics. Let the microchip registry know and confirm your contact information.

Share a clear recent photo, the last-seen location and time, and a contact number. Monitor local found-pet listings as well as posting your own notice. Keep a record of sightings so that you can pass on accurate information.

The BC SPCA’s lost-animal guide outlines reporting, searching and updating identification information. Use the organizations serving the actual search area; the relevant shelter may not be the one nearest your home.

Once your dog is home, close the reports you opened and update public notices. Review how the escape happened and whether every part of the identification process worked as expected.

When someone claims to have found your dog, verify the details before sending money or sharing sensitive information. Ask for a current photograph or arrange confirmation through the clinic or shelter they name, using that organization’s independently verified contact details.

A ten-minute identification review

Set a recurring reminder tied to your licence renewal or another date you will remember. Work through these checks:

• Read the physical tag and confirm the number still works.

• Inspect the tag attachment and walking equipment.

• Open the microchip registry account and review the contact details.

• Check the municipal licence status and next renewal date.

• Confirm that your backup contact is still available.

• Save a recent, clear photograph showing your dog’s distinguishing features.

• Make sure another household member knows where the records are kept.

This small administrative habit is easier to manage before you are dealing with a missing dog.

Common questions about licences and microchips

Does a microchip replace a dog licence?

Do not assume so. The cities discussed here require licensing separately. Calgary’s exception about wearing a tag illustrates why the licence requirement and tag-wearing rule must be checked as different questions.

Can I update my address by changing the information on the chip?

The useful update is to the registry record associated with the chip number. Contact the registry or use its account system; your municipal record may need a separate update.

Does a chip guarantee that my dog will be returned?

No identification method guarantees a reunion. A registered chip with current contact information gives a finder or animal-care organization another way to identify your dog and reach you.

What if my dog already has a tattoo?

Ask the issuing clinic how to keep its records current and whether the tattoo remains readable. Discuss permanent identification options with your veterinarian rather than assuming an older marking is still traceable.

Should I post the microchip number publicly?

Provide it to the registry, animal services, veterinary clinics and other appropriate organizations handling the report. A public missing-dog notice can focus on a photograph, location, description and contact number without publishing your full identification paperwork.
