Beginning in 2020 we have launched a new dog licensing program in partnership with DocuPet. DocuPet’s licensing program includes a FREE Lost Pet Service, the ability to upgrade to a designer tag of your choice, and personalization options.

Pet owners will now be able to choose between two different sizes of licenses to best fit their dog. The small size will be approximately the size of a nickel, while the larger size will be approximately the size of a toonie.

Licenses expire 365 days after the date of purchase.

Your DocuPet tag(s) can be used for multiple years until needing replacement, however each dog(s) licence will need to be renewed annually.

Please keep the 2019 tag on your dog(s) until the 2020 tag arrives, up to 10 business days after renewal.
