Register Online

The city's Dog License Program helps keep the community safe and healthy, and helps reunite lost pets with their guardians. Register online .

A dog license is required for all dogs over the age of four months, living within the city limits of Boulder . You must get a license within 30 days of acquisition of the dog, or within 30 days of moving to the city. All dogs are required to wear their city license tag on their collar or harness at all times.

To obtain a city dog license, your dog must be currently inoculated with a rabies vaccination. The first vaccination is required at the age of four months and needs to be updated every one or three years, depending on the type of vaccination given. Keeping your animals current on their vaccinations prevents the contraction and the spread of various diseases.

All City Dog Licenses are calendar year. Ex:1/1/20XX-12/31/20XX

*Only city of Boulder residents need to purchase a City of Boulder license* 

Purchase a Dog License

Dog guardians can purchase a license at local participating veterinary clinics or by mailing in the registration form located at the right of the page and addressing it to the address printed on the form. You may also register online using a credit card. You may be asked to upload current rabies vaccination documentation at time of renewal or registration. Images of rabies tags  do not count as documentation. Rabies certificates issued by a licensed veterinary clinic are the only accepted form of documentation.

Dog guardians can purchase a renewal dog license online . You may also print off the registration form and mail it in with accompanying paperwork and payment.

For dog guardians outside of the City of Boulder, please contact your local municipality for more information. For questions about the Dog License Program, please call 720-564-2006 or email [email protected] .
